Instrument air: Ensuring the safety and reliability of automated control
In chlor-alkali chemical production, instrument air is used to actuate pneumatic control valves, pressure transmitters, analytical instruments, and other critical automation equipment. It must meet stringent specifications: oil-free, water-free, and dust-free, with a dew point typically below- 40℃, ensuring precise instrument response and long-term stable operation while preventing valve sticking or signal drift caused by impurities.
Process compressed air: Participating in specific chemical reactions and material handling
Certain chlor-alkali process steps require dried and filtered process compressed air, such as pneumatic conveying in the chlorine‑gas treatment system, purging of electrolyzer auxiliary equipment, gas-assisted agitation during sodium hypochlorite preparation, and cylinder purging prior to liquid‑chlorine filling. This type of air must satisfy process‑specific cleanliness and pressure‑stability requirements.
Factory utility air supply: Supporting the efficient operation of auxiliary systems
Compressed air is also extensively used for equipment maintenance purging, backup instrument‑air supply, actuation of pneumatic components on packaging lines, laboratory pneumatic tools, and power for emergency shutoff systems. As one of the plant’s essential utilities, its continuity and quality directly affect the overall facility’s safety and operational efficiency.
