利用二氧化碳资源提高气田开发效益

Use CO_2 Resource to Increase Gas Field Development Benefit

酸性气田开发中应该考虑如何充分利用CO2以提高综合经济效益。CO2可应用于食品、焊接、消防、农业、油气开采、清洗、化工生产等许多行业。我国CO2消费市场潜力很大,高酸性气田巨量的CO2资源若是妥善利用,可产生良好的社会和经济效益。此外,“CO2排放权交易”所潜含的巨大的经济效益也不容忽视。在分析CO2利用项目的技术经济可行性的基础上,通过利用方案对比,建议采用MEA提浓+液化处理的工艺同时生产3×104t食品级和5×104t工业级液体CO2。

How to use the CO2 to increase the profit of sour gas field is worthy consideration. CO2 can be used in many fields, such as food, welding, fire fighting, agriculture , development of oil and gas, cleaning, chemical engineering and so on. At home, the consuming market of CO2 has high potentiality, if the huge amount of CO2 in highly sour gas field can be used efficiently, that will produce good benefit of society and economy. In addition, the tremendous economic benefit resulting from the ' CO2 emission right exchange' shouldn't be ignored. Through the schemes comparing , the suggestion is using MEA (concentrating) + liquefaction to produce 3×104 t liquid CO2(for food) and 5 × 104 t liquid CO2 (for industry).
