试析天然气液化工艺的对比及应用

Analysis and Application of Natural Gas Liquefaction Process

天然气具有无色、无味、无污染、无腐蚀性的特点,被誉为地球上最干净的化石能源。油气田开采出来的天然气经过脱水、脱酸性气体,去除杂质,并经过一连串压缩冷却以后,变成液体,存储在低温储存罐中,因此,被广泛应用在化工、家庭、发电厂等各个领域。文章主要对天然气液化净化、液化循环工艺,通过对两者比较,找到各自的优势,希望能进一步提升天然气液化工艺。

Natural gas is colorless, tasteless, non-polluting, non-corrosive characteristics, known as the earth＇s most clean fossil energy.Oil and gas fields are naturally dehydrated, deacidified, remove impurities, and after a series of compression cooling,into a liquid,stored in low-temperature storage tank,it is widely used in chemical,home,power plants and other fields.By comparing the natural gas liquefaction purification and liquefaction recycling process,the paper found their respective advantages, and hoped to further improve the natural gas liquefaction process.
