摘要
介绍了国内炼厂干气的综合利用现状,提出了一种利用炼厂干气提取轻烃和氢气的新工艺:采用变压吸附和精制生产技术同时生产乙烷/乙烯浓缩气和氢气。将该工艺应用于国内某生产能力5.0 Mt/a的炼油厂,并进行经济性评价。通过优化利用资源,解决了多余的炼厂气烧锅炉或放空的问题,具有较好的经济效益和社会效益。
The current status of utilization of refinery dry gas in China is introduced. A process using refinery dry gas for light hydrocarbon and hydrogen production is developed. The concentrated gas of ethane/ethane and hydrogen is separated by adopting pressure swing adsorption （PSA） and purification technology. The new technology is applied in a refinery with production capacity of 5.0 Mt/a, and the economic evaluation is conducted. The problems of redundant dry gas for firing boiler or emitting into the air can be ultimately resolved by the comprehensive utilization process, and good economic and social benefits are achieved.
