Dear sea friends, what is the purpose of the \"unpurified air\" in utility systems? By the way, is the \"purified air\" intended to supply \"instrument air\", or are there any other uses for it?
Purified air is obtained by removing water and dust from unpurified air, and it is used as air for instruments. Unpurified air is primarily used for purging equipment or devices such as soot blowers
The non-purified air from the gas separation unit is used as the main air for the desulfurization and alkylation system. It can also be used for can stamping (usually not needed in the gas phase, but useful in catalysis). Purified air is used for instruments.
Purified air can be used in various applications that require oxygen, such as oxygen injection for catalytic gasoline desulfurization； Unpurified air can be used for catalyst charring and heating furnace tube charring.
Unpurified air can be used as backup instrument air during short periods when purified air is unavailable, providing temporary emergency support in case of accidents. Additionally, the air used for stirring in each mixing tank is unfiltered air, and equipment such as air pumps and air hammers can also be temporarily connected for use…
After the major overhaul of the gas system, the initial pressure testing is carried out using \"unpurified air\" for pressurization.
In our equipment, unpurified air is used as loosening air and purging air
Unpurified air, also known as industrial air, contains trace amounts of water. Purified air, also known as instrument air, contains no water
