Large air separation plant 40000m3/h, This plant adopts molecular sieve system to adsorb CO2, C2H2, moisture and CnHm in air to pre-purify air, by use of air booster compressor, to pressurize some of purified feed air by two sections, pressurized air to warm up high pressure liquid oxygen in high pressure coil heat exchanger to ambient temperature and delivere out off cold box to coal gasification, some pressurizrd air by first section is drawn from middle part of coil heat exchanger and expanded in medium pressure expander then led into lower column, other part of pressurized air by second section is drawn from cold end of coil heat exchanger and led into lower column after throttling, un-pressurized feed air is cooled by return gas in plate fin heat exchanger and led into lower column.

产品描述：采用常温分子筛空气预净化系统吸附空气中的CO2、C2H2、水份和一些碳氢化合物，使用单独的空气增压压缩机将部分净化后的原料空气分为两段增压，增压后的空气在高压绕管式换热器中将经液氧泵加压的高压液氧汽化并复热至常温送出冷箱直接供煤气化工序使用，第一段增压后的空气，部分从绕管式换热器中部抽出经电机制动的中压透平膨胀机膨胀后送入下塔，另一部分经第二段增压后从绕管换热器的冷端抽出节流后送入下塔，未经增压的原料空气在板翅式换热器中被低压返流气体冷却后进入下塔。
