| Abstract: | Dehydration and desulphurization methods for LNG raw gas were studied. TEG dehydration,solid desiccant dehydration and molecular sieve dehydration were compared, advantages and disadvantages of physical desulfurization were analyzed. Goal is to avoid the freezing of water and hydrocarbon that may plug equipment and pipelines at low temperatures, increase heat value of natural gas to meet air quality standards, ensure that natural gas liquefaction plant can normally run under cold conditions, avoid corrosion of corrosive impurities to pipes and equipment. |
