Research status of oil and gas recovery in the crude oil shipment

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.
