Gas separation recovery facility and gas separation recovery method

摘要

Problem to be solved: to propose a gas separation and recovery system and a gas separation recovery method capable of efficiently separating and recovering plural specific gas components from multicomponent gas mixture.Gas separation and recovery facility 1An adsorption tower row 10 having two or more adsorption columns arranged in series11,Adsorption tower1221２２は、The adsorbent is filledGas introducing piping 11a for introducing gas into the adsorption tower12a,12a,22A andGas discharge piping 11b for discharging gas from the adsorption tower12b.12b.Having 22bA gas discharge pipe 11b (21b) of the upstream side adsorption tower 11 (21) and a gas introduction pipe 12b (22b) of the downstream adsorption tower 12 (22) are connected.Adsorption tower row20 andGas discharge piping 11B of each adsorption tower12b.12b.Exhaust means VP connected to 22b andConnected to the outlet side of the exhaust means VPTwo gas recovery piping 30A switchable by valve operation30b.Diagram
