Oil separator cleaning

You didn't make it clear whether the oil separator is for syngas or synthetic oil. If it is a general oil separator, alkali cleaning can be used to clean it.

According to my understanding, it refers to the oil-water separator for synthetic process gas. In the synthetic circle, oil content mainly refers to supplementary gas oil content and circulating gas oil content. Today, when energy-saving processes are becoming more and more popular, the make-up gas is usually supplied at the inlet or outlet of the ammonia cooler after being separated into oil, and then undergoes ammonia washing with secondary ammonia. ； The oil component of the circulating gas is generally placed after the secondary ammonia component, and the gas from the oil component outlet is exchanged for heat in the heat exchanger outside the tower and then enters the synthesis tower. Therefore, the effect of oil content may directly affect the oil thermal resistance of the entire synthesis system, the catalyst service life, the heat transfer efficiency of the heat exchange equipment, etc. The cleaning of oil-containing internal parts can be divided into online hot cleaning and disassembly cleaning.: Online hot washing means that after the equipment is cut out of the system (the definition is not accurate), the pressure is relieved, the steam line configured with oil is used to blow out the pipeline (if there is no temporary connection, it can be temporarily connected), and steam is introduced for reverse flow flushing. A better way is to add water and then steam for cooking, and discharge it regularly. Even better is to add alkali to the water and then steam it. This method is mainly aimed at the circulating gas and oil separation of multiple circulating machines in parallel. It can be carried out after cutting out the circulating machines and oil separation from the system, or it can also be carried out by taking advantage of the opportunity of short-term parking. Disassembly cleaning is to extract the oil from the internal parts, disassemble them, and clean them with water, steam, and washing oil. This method is time-consuming and labor-intensive and is usually performed during overhaul. This post was last posted by * Edited by aoye613 on 2009-4-20 20:23 ]

The advice above is very good. Just do it like that. Use alkali to clean the grease. If it is still not clean after alkali cleaning, use acid cleaning again.

Will the use of alkali or acid affect the oil separator?

As long as the ratio and operation are well controlled, there will be no problem.
