LNG Plant

Introduction to LNG Processes  The refrigeration and liquefaction sections of any LNG project are very costly items of equipment. A number of cycles have been developed to achieve the low temperatures required. Brief descriptions of a small number of process routes will be give. Some twelve countries were operating by 2003. The cycles employed are the […]

Dehydration

Natural Gas Dehydration Part.1

Definition of Natural Gas Dehydration  the removal of water from natural gas by lowering the dew point temperature of the natural gas    Objective: To prepare natural gas for sale, its undesirable components (water, H2S and CO2) must be removed. Most natural gas contains substantial amounts of water vapor due to the presence of connate […]

dehydration

Natural Gas Dehydration Part.2

PROCESS DESCRIPTION OF GAS DEHYDRATION The principle of glycol dehydration is contacting a natural gas stream with a hygroscopic liquid which has a greater affinity for the water vapor than does the gas. Contactor pressure is subject to economic evaluation usually influenced by water removal duty, required water dewpoint, vessel diameter and wall thickness. After […]
