China National Offshore Oil Co., Ltd. Zhanjiang Branch of the Wenchang oil field well transform existing technology in space is relatively small, production and processing and living quarters module high concentration of FPSO (floating production storage and offloading unit) has successfully built a LPG (liquefied petroleum gas) Recovery, recycling and reuse of resources and technical means to apply the scale to a new level.

since October 2006 has been put into production, the project recycled about 100,000 cubic meters per year of LPG and condensate.

On this basis, Zhanjiang Branch to continue to broaden our thinking, in order to find more associated gas solution: the East end of the flash tower transformation can reduce the burning of natural gas per day nearly 1 million cubic meters of natural gas annual savings 3 million cubic meters; After three years of study, WZ 12-1 oil field was started in September this year, associated natural gas re-injection into the formation, this can not only enhance oil recovery in the future can also be angry with the nearby oil fields collection storage, into a large underground tanks to be comprehensive utilization of associated gas; WZ terminal naphtha treatment plant utilization of natural gas, liquefied petroleum gas recycled 150 cubic meters per day, 200 cubic meters of condensate per days for the gas to local firms can also be nearly 25 million cubic meters.

WZ a new oil field operation area of the de-butane tower of light hydrocarbon recovery unit condenser effect of heat transfer deterioration, making part of the liquefied gas in the form of venting gas to the torch. To solve this problem, if we adopt the cut-off take apart and wash heat exchanger, stop loss is 460 thousand yuan a day, take apart and wash at least 3 days. Operation area through the careful study of process systems, decided to add a control valve on the return of de-butane tank venting tower reasonable transformation pipeline without shutdown on the loss of the liquefied gas to run all been a recovery, produced a month economic benefit of 300 million yuan.

中海油湛江分公司大力发展循环经济

中国海洋石油有限公司湛江分公司的文昌油田以及改造现有技术在空间相对较小，生产加工和生活区模块高度集中的FPSO（浮式生产储卸油装置）已经成功地建立了液化石油气（液化石油气）回收，循环利用和资源再利用技术手段和适用范围到一个新水平。

自2006年10月已投产，该项目回收约10万液化石油气和凝析油立方米。

在此基础上

，湛江分行继续扩大我们的思想，以找到更多的伴生天然气的解决方案：闪光的东塔改造结束，可以减少每天燃烧天然气近100万立方米天然气天然气每年可节省三〇 〇 〇 〇 〇 〇立方米;经过三年的研究，涠洲12-1油田于今年9月开始到形成相关的天然气重新注入，多年来，这不仅可以提高石油在今后的恢复也可以愤怒与邻近的油田收集储存到一个大型地下坦克，成为伴生天然气综合利用;涠洲终端处理石脑油，天然气液化石油气，每天回收150立方米，利用植物，200立方米，凝析油为每天对当地企业气体也可近2500万立方米。

涠洲新油田的作业区德的轻烃回收装置的传热恶化丁烷塔冷凝器的效果，使排气中的天然气火炬构成液化气的一部分。为了解决这个问题，如果我们采取切断拆洗换热器，停止损失46.0万元，每天拆洗至少3天。通过运行系统的过程中认真研究领域，决定增加对日返回丁烷罐排气没有对液化天然气的合理损失关机塔改造管道运行所有被回收控制阀，制作了一个月的经济利益300万元人民币。08.12.10
