Parallel Plate Interceptor Design Diagram
The parallel plate interceptor (PPI) is the early form of a plate coalescer. The basic design of parallel plate interceptor is a series of plates installed parallel to the longitudinal axis of an API separator as shown in figure above. … Continue reading
SP Pack Separator
The SP Pack separator is developed by Paragon Engineering Services, this separator creates turbulent flow by forcing the water to flow through a serpentine pipe path. The path is correctly size to create a correct turbulence to cause coalescence but … Continue reading
Dissolved Gas Flotation Unit
Dissolved gas unit allows the water and gas saturation in a contactor. A typical Dissolved gas unit works on 20 to 40 psig contact pressure, more gas can be saturated in higher pressure. The water is taken from the treated … Continue reading
Increasing Retention Time to Create Larger Water Droplet
A small increase in water droplet diameter will increase the settling rate since water droplet is squared in the settling equation. The water droplet size will increase within a retention time in the coalescing section, adding a heat input will … Continue reading
Gravity Separation Velocity Calculation
The gravity force is commonly used in oil treating equipment to separate the water from the oil in continues phase; the water droplet tends to separate from the oil since it’s heavier than the oil. The separation speed is limited … Continue reading
Oil Treating System Design Consideration
Crude oil outputted from production separator may contain some water. The water is removed from crude oil through an oil treating process. There are factors to consider designing the oil treating system. Some major factors are: 1. Emulsion tightness. 2. … Continue reading
