摘要 MEG是贫乙二醇的简称,常作为油气脱水剂广泛应用于海洋油气开采中。在工业实际应用中,MEG极易吸水而形成水、乙二醇的混合溶液,该混合溶液极易导致钢铁材质的贫乙二醇罐腐蚀造成泄漏。热喷铝涂层本身极耐腐蚀,并且能阻止水、空气及其它腐蚀介质到达钢铁基体。同时,热喷铝层本身不溶于贫乙二醇和水,是贫乙二醇罐内部防腐的首要防腐方式。MEG存储罐由罐体、内部工艺管线和热喷铝防腐涂层组成。详细描述MEG存储罐的罐体制造、管线安装、焊缝密性检查、压力测试以及热喷铝施工工艺和注意事项。 MEG is the abbreviated term of lean glycol,which is widely used as an oil/gas dehydrating agent in offshore oil and gas production.In the practical application of the industry,MEG is easy to absorb water to form a mixed solution of water and ethylene glycol,which can easily lead to the leakage of the poor ethylene glycol tank.Thermal sprayed aluminum coating has better physical coverage,the steel matrix with water,air and other media are separated,and thermal spraying aluminum layer is not dissolved in ethylene glycol and water is poor,so thermal spray aluminum is the first way to protect corrosion of MEG tank.The MEG storage tank is composed of a tank body,an internal process pipeline and a thermal spraying aluminum coating.This paper discusses in detail the construction of MEG storage tank,pipeline installation,weld tightness test,pressure test,thermal aluminum spraying process and concerns.
