Necessity Of Chemical Cleaning For Methanol Plant

Necessity of chemical cleaning for methanol plant

There are still some pollutants in the newly purchased equipment, especially the welding slag, welding flux and antirust oil in the pipe wall. If they are used directly without treatment, they will cause great pollution to the products produced.

Because the clean metal surface can be obtained after chemical cleaning, it can produce * * products more quickly, and the economic benefit obtained by the factory will greatly exceed the investment cost of cleaning. In recent years, China has introduced many sets of large-scale chemical plants from abroad one after another. It is also for this purpose that foreign businessmen stipulate that these plants must undergo chemical cleaning before starting.

Take methanol for example, the gas purification in methanol production process mainly refers to the removal of sulfur-containing gas impurities in natural gas. Some components of the residual dirt in the pipeline and equipment are easy to react with the desulfurization solution, which affects the purification effect of feed gas. If the sulfur-containing gas in natural gas is not cleaned up, it will be extremely harmful to the further conversion and subsequent synthesis of the gas.
