Description
合成ガス流は、主として一酸化炭素及び水素を含む気体流である。合成ガス流は、例えば天然ガス、炭層メタン、留出油、及び残油などの炭化水素の部分酸化又は水蒸気改質によるか、或いは石炭又はコークスのような固体化石燃料のガス化によって製造される。合成ガスの製造に関する一般的な説明に関しては、"The Shell Middle Distillate Synthesis Process, Petroleum Review, 1990年4月, pp.204-209", Maarten van der Burgtらを参照されたい。
−初期圧力及び初期温度の気体流を与え;
−気体流を圧縮し;
−圧縮した気体流を冷却し、ここで圧縮及び冷却した気体流は気体流中のCO2が少なくとも部分的に液相に転化する増加した圧力及び低下した温度を有し;そして
圧縮及び冷却した気体流から液相を分離して、出口圧力の液相流及び気相流を与える;
工程を含み;
液相流の出口圧力が気体流の初期圧力と比較して上昇している;
合成ガス流又は燃焼排ガス流からCO2を分離する方法を提供する。
他の形態によれば、本発明は、
−初期圧力及び初期温度を有する気体流を圧縮するための圧縮器;
−圧縮した気体流を冷却する(ここで、圧縮及び冷却した気体流は気体流中のCO2が少なくとも部分的に液相に転化する圧力及び温度を有する)ための少なくとも1つの冷却装置;及び
−圧縮及び冷却した合成ガス流を出口圧力において液相流及び気相流中に分離するための分離器;
を含み、
液相流の出口圧力は気体流の初期圧力と比べて増加している;
CO2を含む気体流からCO2を分離するためのシステムを提供する。
液相流120は、場合によっては圧縮した気体流を更に冷却するための第2の熱交換器110(図1)又は第1の熱交換器(図2)に送ることができる。
他の態様(図4)においては、熱交換器108及び110に代えて多重流熱交換器109を用いることができる。
として公式化することができる。
液相生成物流は、約90〜98モル%のCO2、<5モル%のH2、及び/又は<1モル%のCOを含むようにすることができる。
本発明の上記記載の幾つかの態様は非限定的であると意図される。特許請求の範囲内においてその多くの修正を想到することができる。
