Natural Gas Dehydration Modeling Using Liquid Absorbents to Maintain Continuous Oil Production in Gas Lift Operation in Secondary Recovery of an Oil Reservoir

At present, crude oil is considered as the most important and common raw material in the world economy. The stop ofcrude oil production for any reason will lead to many economic problems damages. Gas injection in to a well isrequired for the secondary extraction from an oil reservoir. The whole oil production process depends on gas lift or gasinjection. Crude oil extraction is improbable in case no gas is injected. The major problem in gas injection into wells isthe presence of humidity in gas. Humidity may frost the casing chock valves of wells, which close the aperturecompletely. Temperature drop occurs due to the considerable pressure drop in the aperture. Aperture obstruction stopscrude oil extraction from a well and damages the turbine of compressors. Therefore, we have to control humiditycontent in the injected gas and apply dehydration systems to prevent continuous crude oil production.Design and Modeling of natural gas dehydration by liquid absorbent TEG, (three ethylene glycol),to maintaincontinuous oil production in GAS LIFT operation in secondary recovery of an oil reservoir and lean TEG regeneration,was prepared.
