中文摘要：

为了研究原油装船过程中油气回收技术发展现状,综合国内外应用现状和相关排放法规,分析了对国内原油装船过程中油气回收技术研究的必要性,指出大处理量、高含硫量是目前岸上油气回收处理装置需要克服的难点。装船过程中油气浓度是变化的,其中后20%装船过程的油气浓度波动剧烈。国外在油气回收技术领域的研究探索已有50年的历史,拥有油品码头油气回收一系列比较成熟的技术。当前原油油气回收主要采用燃烧法、吸收法、吸附法、冷凝法及其组合工艺,其中以吸附-吸收法、冷凝-吸收法最为常用,膜分离法不适宜使用。（图4,表6,参17）

英文摘要：

To understand the status of oil and gas recovery in the shipment of crude oil, the applications of the technique and relevant emission regulations in China and abroad are coalesced to judge the necessity of research thereof. It is revealed that large processing capacity and high sulfur content are challenges for onshore oil and gas recovery device. Concentration of oil and gas changes in shipment, and even violently in last 20% of the shipment process. In foreign countries, the research and exploration of oil and gas recovery were initiated 50 years ago, where a series of mature technologies have emerged for oil and gas recovery in oil terminals. Oil and gas are recovered in crude oil shipment by combustion, absorption, adsorption, condensation and the combination thereof. The adsorption-absorption and condensation-absorption are the most commonly used, while the membrane separation is unsuitable.
