Steam Reboilers: Ensuring Optimal Performance through Proper Balance Line Sizing
Steam reboilers are a fundamental component in the distillation process within petroleum refineries and petrochemical plants. They play a pivotal role in transferring heat to the bottom of a distillation column, which is essential for the separation process. The balance between the condensate vessel and the reboiler is critical for efficient operation.
Why Balance is Important: The balance line between the condensate vessel and the reboiler ensures that the liquid level in the reboiler remains constant, preventing issues such as flooding or dry-out conditions. Flooding can lead to reduced heat transfer efficiency and potential damage to equipment, while dry-out conditions can cause overheating and tube failure.
The Role of a 1–2-inch Balance Line: A 1–2-inch balance line is often sufficient for maintaining this delicate balance. It allows the condensate to flow back into the reboiler as it condenses, maintaining a steady level and ensuring that the reboiler can operate continuously without interruption.
Impact of Balance Line Sizing on Reboiler Operation
| Balance Line Diameter (inches) | Potential Impact on Operation |
|---|---|
| Less than 1 | Increased risk of reboiler dry-out due to insufficient return flow |
| 1–2 | Optimal range for continuous and stable operation |
| Greater than 2 | Potential for flooding if the return flow exceeds evaporation rate |
The proper sizing and placement of a balance line are crucial for the successful operation of steam reboilers. It ensures the stability of the distillation process, maximizes heat transfer efficiency, and minimizes the risk of equipment damage. Operators must carefully consider the design and operation parameters to maintain the delicate balance required for optimal reboiler performance.

Electrochemical direct-air capture of CO2 also produces freshwater from brine
A new electrochemical technology for direct-air capture (DAC) of atmospheric CO2 can also produce freshwater from brackish water or brine waste from desalination or wastewater treatment facilities. The technology, developed by Capture6, a cleantech company based in Berkeley, California, splits the salt content of the water into acid and base solutions, which are then used to capture CO2 from the air and produce valuable byproducts.
The process is based on electrodialysis, a membrane-based separation technique that uses an electric potential to drive ions across selective membranes. By applying a voltage across a stack of alternating anion-exchange and cation-exchange membranes, the salt water is separated into two streams: one with a high pH (base) and one with a low pH (acid). The base stream is then sprayed over a gas diffusion electrode, where it reacts with CO2 from the air to form bicarbonate ions. The acid stream is used to regenerate the base stream by removing the bicarbonate ions and releasing CO2, which can be compressed and stored or utilized in various applications. The remaining water in both streams is purified and recovered as freshwater.
The advantages of this electrochemical DAC technology are its low energy consumption, scalability, and compatibility with renewable energy sources. According to Capture6, the technology can capture CO2 at a cost of $50 per ton, while producing up to 75% of freshwater from the salt water input. The technology can also generate other valuable products, such as calcium carbonate for concrete, lithium salts for batteries, and hydrogen gas for fuel cells.
Capture6 is currently testing its technology at a pilot facility in California, in partnership with Palmdale Water District. The facility uses brine waste from a reverse osmosis desalination plant as the salt water input, and aims to demonstrate the feasibility and performance of the electrochemical DAC process. Capture6 plans to scale up its technology and deploy it in various locations, such as coastal areas, islands, and arid regions, where water scarcity and carbon emissions are major challenges.
The Future of Carbon Capture and Storage with Carbonate Fuel Cells
ExxonMobil affiliate Esso Nederland B.V. (Rotterdam, the Netherlands; www.esso.nl) is planning to build a pilot plant at its Rotterdam manufacturing complex to generate performance and operability data for a modular carbon-capture and storage (CCS) technology based on carbonate fuel cells.
The pilot plant, which is expected to be operational by late 2024, will test the feasibility of using carbonate fuel cells to capture CO2 from flue gas streams of natural gas-fired power plants and industrial facilities. The project is part of a joint development agreement between ExxonMobil and FuelCell Energy, Inc. (Danbury, Conn.; www.fuelcellenergy.com), a leading developer of carbonate fuel cell technology.
What are carbonate fuel cells and how do they work?
Carbonate fuel cells are a type of high-temperature fuel cells that use a molten mixture of salts, such as lithium, sodium, and potassium carbonate, as the electrolyte. The electrolyte conducts carbonate ions (CO32-) from the cathode to the anode, where they react with hydrogen and carbon monoxide from the fuel to produce water, carbon dioxide, and electricity. The fuel can be derived from natural gas, biogas, coal, or other sources. The carbon dioxide produced at the anode can be separated and compressed for transportation and storage, while the excess heat and electricity can be used for power generation or other purposes.
The advantages of carbonate fuel cells include high efficiency, low emissions, fuel flexibility, and scalability. Carbonate fuel cells can achieve efficiencies of up to 60%, compared to 37–42% for conventional power plants. They also have lower emissions of nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter, as well as lower water consumption. Carbonate fuel cells can use a variety of fuels, including natural gas, biogas, coal gas, and hydrogen, without the need for external reforming. They can also be configured in modular units that can be easily installed and expanded.
How can carbonate fuel cells be used for carbon capture?
Carbonate fuel cells can be used for carbon capture in two ways: direct fuel cell carbon capture and exhaust gas carbon capture.
- Direct fuel cell carbon capture: In this method, the fuel cell itself acts as a carbon capture device, as it produces a concentrated stream of CO2 at the anode that can be easily separated and stored. This method can be applied to any fuel cell system that uses carbon-containing fuels, such as natural gas, biogas, or coal gas. The advantage of this method is that it does not require any additional equipment or energy for carbon capture, and it can also increase the power output and efficiency of the fuel cell system by reducing the parasitic load of CO2 removal.
- Exhaust gas carbon capture: In this method, the fuel cell is used to capture CO2 from the exhaust gas of another power plant or industrial facility. The exhaust gas, which contains about 8–15% CO2 by volume, is fed to the cathode of the fuel cell, where it reacts with oxygen and carbonate ions to produce water and CO2. The CO2 is then transferred to the anode, where it can be separated and stored. The advantage of this method is that it can be retrofitted to existing power plants and industrial facilities, and it can also generate additional electricity from the fuel cell.
| Method | Fuel cell system | Carbon capture device | CO2 concentration | Power output | Efficiency |
|---|---|---|---|---|---|
| Direct fuel cell carbon capture | Any fuel cell system that uses carbon-containing fuels | Fuel cell anode | High (90–100%) | Increased | Increased |
| Exhaust gas carbon capture | Fuel cell system that uses hydrogen or other non-carbon fuels | Fuel cell cathode | High (90–100%) | Additional | Slightly decreased |
What are the benefits and challenges of carbonate fuel cell carbon capture?
Carbonate fuel cell carbon capture has several benefits over conventional carbon capture methods, such as amine scrubbing or membrane separation. These benefits include:
- Higher efficiency: Carbonate fuel cell carbon capture can reduce the energy penalty of carbon capture by generating electricity from the fuel cell, while conventional methods consume energy for CO2 separation and compression. According to a study by the US Department of Energy, carbonate fuel cell carbon capture can increase the net efficiency of a natural gas power plant from 49.9% to 55.3%, while amine scrubbing can decrease it to 40.4%
- Lower cost: Carbonate fuel cell carbon capture can reduce the cost of carbon capture by avoiding the need for expensive solvents, membranes, or other materials, as well as reducing the size and complexity of the carbon capture equipment. According to a study by ExxonMobil and FuelCell Energy, carbonate fuel cell carbon capture can reduce the cost of carbon capture by up to 67%, compared to amine scrubbing
- Lower emissions: Carbonate fuel cell carbon capture can reduce the emissions of other pollutants, such as NOx, SOx, and particulate matter, by using a cleaner and more efficient fuel cell system, while conventional methods may increase the emissions of these pollutants due to the increased fuel consumption and flue gas recirculation. According to a study by the US Department of Energy, carbonate fuel cell carbon capture can reduce the NOx emissions of a natural gas power plant by 98%, compared to amine scrubbing
However, carbonate fuel cell carbon capture also faces some challenges that need to be overcome before it can be widely deployed. These challenges include:
- Durability: Carbonate fuel cells operate at high temperatures (600–700 °C) and use corrosive electrolytes, which can accelerate the degradation and corrosion of the fuel cell components and materials, decreasing the cell life and performance. Scientists are currently exploring corrosion-resistant materials and fuel cell designs that can increase the durability and reliability of the fuel cell system
- Scalability: Carbonate fuel cells need to be scaled up to match the large volumes of CO2 produced by power plants and industrial facilities, which can pose technical and economic challenges. Scientists are currently developing modular and flexible fuel cell systems that can be easily installed and integrated with existing facilities
- Regulation: Carbonate fuel cell carbon capture needs to comply with the regulatory and legal frameworks for carbon capture and storage, which can vary by region and country. These frameworks need to address the issues of CO2 transportation, storage, monitoring, verification, and liability, as well as the incentives and policies for carbon capture and storage deployment
What are the current and future prospects of carbonate fuel cell carbon capture?
Carbonate fuel cell carbon capture is still in the early stages of development and demonstration, but it has shown promising results and potential for commercialization. Some of the current and future projects and initiatives involving carbonate fuel cell carbon capture are:
- The pilot plant at Rotterdam: This project, which is a collaboration between ExxonMobil and FuelCell Energy, aims to build and operate a 10-MW pilot plant that will use carbonate fuel cells to capture CO2 from the flue gas of a natural gas-fired power plant at the Rotterdam manufacturing complex. The project will test the performance and operability of the fuel cell system, as well as the integration with the existing power plant and the CO2 transportation and storage infrastructure. The project is expected to be operational by late 2024 and will capture up to 100,000 metric tons of CO2 per year
- The Southern Company project: This project, which is funded by the US Department of Energy, aims to demonstrate the feasibility and economics of using carbonate fuel cells to capture CO2 from the exhaust gas of a coal-fired power plant. The project will use a 2.7-MW fuel cell system provided by FuelCell Energy to capture up to 70% of the CO2 from a slipstream of the flue gas of a 770-MW power plant operated by Southern Company in Alabama. The project is expected to be completed by 2023 and will capture up to 10,000 metric tons of CO2 per year
- The Carbon Capture Coalition: This is a coalition of more than 80 companies, organizations, and associations that support the development and deployment of carbon capture and storage technologies in the US. The coalition advocates for policies and incentives that can accelerate the commercialization and adoption of carbon capture and storage, including carbonate fuel cell carbon capture. The coalition also facilitates the collaboration and communication among the stakeholders and the public on the benefits and challenges of carbon capture and storage
Carbonate fuel cell carbon capture is an innovative and promising technology that can offer a viable solution for reducing CO2 emissions from power plants and industrial facilities, while also generating additional electricity and reducing other pollutants. The technology has the potential to play a significant role in the transition to a low-carbon economy and the mitigation of climate change. However, the technology also faces some technical, economic, and regulatory hurdles that need to be overcome before it can be widely deployed. Therefore, more research, development, demonstration, and collaboration are needed to advance and commercialize carbonate fuel cell carbon capture.
A novel forward osmosis approach for organic solvent dehydration in pharmaceutical manufacturing
Organic solvents are widely used in the pharmaceutical industry for various purposes, such as dissolving active ingredients, performing reactions, purifying synthesis products, and enhancing the bioavailability of orally administered drugs. However, these solvents often need to be dehydrated to achieve the desired results, especially for processes such as crystallization. The conventional methods for dehydration, such as vacuum distillation, require the application of heat and pressure, which are not only time- and energy-consuming, but may also have negative effects on the quality and stability of the pharmaceutical intermediates, especially those that are sensitive to heat.
To overcome these challenges, researchers at Asahi Kasei Corp. (Düsseldorf, Germany and Tokyo, Japan; www.asahi-kasei.com) have developed a novel membrane-based system that dehydrates organic solvents without heat or pressure. The system is based on the phenomenon of forward osmosis, in which a liquid moves through a semipermeable membrane due to concentration differences. The system consists of a hollow-fiber membrane module and a draw solution that are suitable for organic solvents used in pharmaceutical manufacturing.
The membrane module contains polymer membranes that are selectively permeable to water, but not to the organic solvents or the pharmaceutical intermediates. The draw solution is a concentrated solution that creates a high osmotic pressure across the membrane, driving the water from the organic solvent to the draw solution side. The draw solution is then regenerated by removing the water and recycled back to the system.
The advantages of this membrane system are manifold. First, it can dehydrate organic solvents below 1,000 ppm without applying heat or pressure, thereby minimizing the impact on heat-sensitive pharmaceutical intermediates. Second, it can handle a variety of organic solvents, including alcohols, ethers, esters, and hydrocarbons, as well as highly soluble liquids, such as tetrahydrofuran (THF), toluene, or methanol. Third, it can shorten the process time and reduce the energy consumption compared to vacuum distillation. Fourth, it can prevent the loss of pharmaceutical intermediates, as they are retained on the organic solvent side of the membrane.
The following table summarizes the main features and benefits of the membrane system compared to vacuum distillation:
| Feature | Vacuum distillation | Membrane system |
|---|---|---|
| Dehydration method | Heat and pressure | Forward osmosis |
| Water content in organic solvent | < 1,000 ppm | < 1,000 ppm |
| Impact on heat-sensitive intermediates | High | Low |
| Solvent compatibility | Limited | Wide |
| Process time | Long | Short |
| Energy consumption | High | Low |
| Loss of intermediates | Possible | None |
The membrane system is currently undergoing practical verification in collaboration with Ono Pharmaceutical Co., Ltd., one of the largest pharmaceutical companies in Japan. The commercialization of the system is targeted for 2027. The system is expected to contribute to the optimization of manufacturing processes and the improvement of product quality in the pharmaceutical industry.
