摘要:

随着我国经济快速发展,对天然气这种清洁能源的需求不断增长,天然气工业逐渐步入新的发展期。离子液体技术、膜分离、生物脱硫等前沿技术的研究为天然气脱硫技术拓展了新的途径,推动现有技术朝着环保化、精细化、科技化方向发展。随着老气井的增产作业及新气田的开发,原料气气质变化趋向复杂化。为满足国家日益严格的环保标准及国家对能源的战略需求,迫切需要对天然气净化技术的研究方向及发展进行更深入的思考并开展技术攻关。

Abstract:

With the rapid economic development in China,the growing demand for natural gas as a clean energy,natural gas industry has gradually been going into the period of development.Many frontier technologies,such as ionic liquid technology,membrane separation,biological desulfurization,exploit a new way for the existing gas desulfurization technology,and promote existing technology development to the direction of environmental protection,refinement,science and technicalization.However,with the stimulation of the old gas well and development of the new gas fields,the variation of the raw gas components tends to be complicated.To meet the stricter environment standards and energy strategic demands of China,it is urgent to take into deep consideration about research direction and development of natural gas purification technology and strive to make technological breakthrough.
