The role of small air separation unit dcs system
Grounding is to achieve a low impedance link between the circuit, the Danyun, and the first-class point or the equipotential surface that is used as the common reference point of the signal. The grounding of the dcs system is to ensure that when the signal entering the dcs system, the power supply or the equipment of the dcs system has a problem, the effective grounding system can withstand the overload current and can quickly lead the overload current to the ground.

Cryogenic air separation nitrogen production uses air as raw material, which is compressed, purified and heat exchanged to liquefy gas air into liquid air. Liquid air is mainly a mixture of liquid oxygen and liquid nitrogen. Liquid oxygen and liquid nitrogen have different boiling points and are separated by distillation to obtain nitrogen. 1. Air compression and purification The air passes through the air strainer to remove dust and mechanical impurities, then enters the air compressor, compresses to the required pressure, and then goes to the air cooler to reduce the air temperature. It then enters the air drying purifier to remove moisture, carbon dioxide, acetylene and other hydrocarbons from the air. 2. Air separation The purified air enters the main heat exchanger in the air separation column, and is cooled to the saturation temperature by the reflux gas (production nitrogen gas, waste gas), and is sent to the bottom of the distillation column. The nitrogen is obtained fr
