摘要
文章介绍 1999年 1月建成投运的 2× 10 4m3 /d“陕北气田液化天然气示范工程”是发展我国LNG工业的先导工程 ,也是我国第一座小型LNG工业化装置。该装置的主要特点是 :①采用天然气膨胀制冷循环 ;②采用低温甲醇洗和分子筛干燥联合进行原料气净化 ;③采用气波制冷机和透平膨胀机联合进行低温制冷 ;④采用燃气机作为循环压缩机的动力源 ;⑤利用燃气发动机的尾气作为加热分子筛再生气的热源。本装置设备全部国产化。该装置的成功投运为我国在边远油气田上利用天然气生产LNG提供了经验。
As the 'LNG demonstrating project in North Shannxi gas field', the natural gas liquefying device with a deliverability of 20 × 103m3/d, which was built up and went into operation in January 1999, is the guiding project of developing LNG industry in China and is the first small LNG industrialized device in China. The major characteristics of the device are: 1. to make use of natural gas expanding refrigeration recycle; 2. to purify material gas by both low temperature methanol washing and molecular sieve drying; 3. to get cryogenic refrigeration by gas wave machine and turbin expanding motor; 4. to take advantage of gas engine as the power of recycle gas compressor; and 5. to make use of the exhaust gas of gas engine as the thermal source of heating molecular sieve regeneration gas. All the units of the device are made in China and this device's being successfully put into operation has provided experience for producing LNG by use of the natural gas exploited from the remote oil and gas fields in China.
