Waxy substance at the bottom of the methanol storage tank

What is the main component of the waxy substance at the bottom of the methanol storage tank? What is its purpose? As fuel?

It’s because of the problem with the coal you use. . . . . . . Generally, steam is introduced to melt it

It can be removed using an iron spade; once the alcohol has been used up, the wax buildup that remains from the initial period of driving or during operation stays there

Paraffin must be removed after parking to prevent it from entering the distillation system.

I also think it should be paraffin; it is brought into the storage tank along with crude methanol during the production process, accumulates, and then settles at the bottom of the tank. Therefore, the methanol storage tank should have its blockages cleared from time to time whenever it is shut down.

It’s paraffin, it’s completely normal. Some of the crude methanol will certainly still make its way into the crude methanol storage tank after passing through the synthesis filter. Over time, it will accumulate. There are also some iron filings in the wax, and the inlet of the impurity removal pump can be clogged by waxy substances as well

After rinsing with water, it can be removed with a shovel.

It is paraffin; under the action of a copper-based catalyst, it is produced at around 170 degrees Celsius. There are also some impurities present, such as rust and catalyst residues, which can be melted away using steam in water coolers and separators, and then removed from the system; The paraffin in the storage tank can be removed with a shovel after the machine is shut down, and then cleaned thoroughly with steam. Prolonged accumulation of paraffin leads to its backflow into the feed heat exchanger of the distillation pre-tower, causing wax blockage that requires shutdown for cleaning.

It’s wax; no shovel is needed – a plastic or wooden shovel can be used to remove it.

The main components are paraffin and high-grade fusel oils; they are of no use in our company and are treated as waste

The main component is paraffin. After parking, purge with nitrogen and, once safety is ensured, enter to shovel out and clean it away; if there is any on the walls as well, clean that off as well. Otherwise, it will cause cooling at the distillation baffle.

It is paraffin, a by-product of synthetic reactions; it must be removed through mechanical and physical methods to prevent it from clogging pipes in subsequent processes and disrupting production. Because it adheres to the heat exchanger after entering subsequent processes, affecting heat transfer efficiency and blocking the channels of control valves, which poses a serious risk! !
