一、甲醇回收装置运行现状(一)概况长庆油田公司第一净化厂共建成含甲醇污水处理装置2套,设计处理能力分别为100m~3/d和50m~3/d。近年来由于气田含甲醇污水水量波动大,且污水中的Cl~-、SO~(2-)4、HCO_3~-大量存在,对设备和管线腐蚀性较强。此外,通过分析发现,污水中还含有大量能够加速装置结垢的Sr~(2+)、Ba~(2+)。目前第一净化厂含甲醇污水在精馏处理前
First, the methanol recovery plant operation status (a) Overview Changqing Oilfield Company No. 1 purification plant built a total of two sets of methanol wastewater treatment plant, design and processing capacity of 100m ~ 3 / d and 50m ~ 3 / d. In recent years, because of the large fluctuation of the water volume of methane-containing wastewater in the gas field and the large amount of Cl ~ -, SO ~ (2-) 4 and HCO_3 ~ in the sewage, the corrosion on the equipment and pipeline is strong. In addition, it is found through analysis that the sewage contains a large amount of Sr2 + and Ba2 + which can accelerate the scaling of the device. At present, the first purification plant containing methanol wastewater before rectification
