Based on the principle that the adsorption capacity of adsorbent in the adsorption tower for vinyl chloride and acetylene varies with pressure, the raw gas after heat transfer and pressure pressurization enters the adsorption tower of the pressure swing adsorption device. The strong adsorption of vinyl chloride and acetylene is absorbed by the adsorbent. Weak adsorbent H2 and N2 are discharged from the outlet of the adsorption tower as purified gas. When the adsorption bed is saturated, the adsorbed components such as chloroethylene and acetylene are desorbed and desorbed from the adsorption bed through reverse discharge and empty, and then are discharged into the adsorption column as the product gas, and returned to the chloroethylene production process for recycling, so as to achieve the dual purpose of purification and recovery of chloroethylene and acetylene.
How it works:
Based on the principle that the adsorption capacity of the adsorbent in the adsorption tower for vinyl chloride and acetylene varies with the change of pressure, the raw material gas after heat transfer and pressure enters the adsorption tower of the pressure swing adsorption device, the strong adsorption of vinyl chloride and acetylene is adsorbed by the adsorbent, and the weak adsorption substances H2 and N2 are discharged from the adsorption tower as purification gas. When the adsorption bed is saturated, the adsorbed vinyl chloride and acetylene components are desorbed and desorbed from the adsorption bed through reverse discharge and evacuation, and the adsorption tower is discharged as product gas, and the vinyl chloride production process is returned to be recovered, so as to achieve the dual purpose of purification and recovery of vinyl chloride and acetylene.
Control mode and characteristics:
Control mode: Use controller and instrument to control PSA device. The controller can choose DCS, FCS, PLC control system according to PSA device scale and control requirements.
Control features: not only the conventional control of the system is realized, but also the expert control and adaptive optimization control of any combination and arbitrary switching of multiple towers are realized, which not only improves the flexibility of the operation of the device, but also ensures the long-term, stable and safe operation of the PSA device.
PSA device features:
The adsorbent has long service life, higher purification precision and higher recovery rate
The operation flexibility of the device is large and the degree of automation is high
The opening and stopping of the device has no disturbance to the operation of the front and rear sections
