Abstract: Theemulsification research results of the Claus fan lube oil show that there are two main reasons for the emulsification of KG301 lube oil: one is that the sealing gasket of the lube oil tank is gradually aging, so the water phase of the heat exchanger enters the oil tank, which results in the emulsification of the lube oil in the water; the second reason is the degradation of the lube oil after long-term use. Aiming at the aging problem of the sealing gaskets, new gaskets have been developed and the aged ones have been replaced. Two countermeasures have been taken to deal with the problem of lube oil degradation: one is to add new lube oil regularly; the other is to develop cheap and high-quality lube oil and prepare for practical application tests. Meanwhile, the chemical composition of in-service lube oil is analyzed continuously and regularly to ensure the sealing performance of the lube oil system. The emulsification problem of Claus fan lube oil was solved successfully, and the purpose of reducing costs and increasing efficiency was achieved.
