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

Gas Dehydration Methods

Before gas can be sold the gas need to be dehydrated from its water content. This efforts need to be done to prevents hydrates and water vapor. The water vapor in gas line could create corrosion problems. There are many … Continue reading

Lease Automatic Custody Transfer (LACT) Working Principle

As we can see on the schematic, the first stage of Lease Automatic Custody Transfer (LACT) system is a strainer/gas eliminator. The strainer is needed to remove the gas from crude so it wouldn’t damage the meter. The crude then will … Continue reading
