The function of the air separation unit in a chemical plant
Thread Content
The empty processing section plays a crucial role in chemical plants; can everyone list its importance?
Air is separated to yield high-purity components such as oxygen, nitrogen, and inert gases, which serve as raw material gases and utility gases for subsequent chemical manufacturing processes.
Using air as the raw material, oxygen, nitrogen, and argon are primarily separated from it. Nitrogen can be supplied to other devices for use as power or for purging purposes, or it can also be turned into liquid nitrogen and sold in tanks； Oxygen and argon can also be made into liquid or gas form. It's mainly these three gases.
Several of the factories visited were unable to operate at full capacity due to their overly small air separation units
Nitrogen is used in chemical production for pressurization, purging, as safety nitrogen, and for replacement during shutdowns; however, the amount of nitrogen used in these applications is not very large. The main demand for nitrogen comes from steel mills for oxygen production and from ammonia synthesis plants.
One of the main products of air separation units is instrument air (purified air), which serves as the power source for factory automation control systems； The high-purity nitrogen it provides can be used as a gas source for safe production and measurement...
I work at Texaco Gasification. The main functions of the air separation unit in our plant are to supply high-purity oxygen required for gasification, high-pressure nitrogen for purging during startup and shutdown operations, as well as low-pressure nitrogen for displacement purposes. It also provides instrument air, plant air, and medium-pressure nitrogen needed for the sulfidation of conversion catalysts.

Which brand of e-cigarettes is better? Can rhinitis be completely cured? How can formaldehyde be removed effectively?
Is it now common for air separation facilities to be built as large-scale projects, with multiple chemical projects sharing them in order to reduce costs?
