Five of them were installed in Madhya Pradesh, four in Maharashtra, three each in Chandigarh, Gujarat and Uttarakhand, two each in Bihar, Karnataka and Tamil Nadu and one each in Andhra Pradesh, Chhattisgarh, Delhi, Haryana, Kerala, Maharashtra, Puducherry, Punjab and Uttar Pradesh.
Pressure swing adsorption (PSA) is a technology used to separate some gas species from a mixture of gases under pressure according to the species’ molecular characteristics and affinity for an adsorbent material.
It operates at near-ambient temperatures and differs significantly from cryogenic distillation techniques of gas separation.
Specific adsorbent materials (e.g., zeolites, activated carbon, molecular sieves, etc.) are used as a trap, preferentially adsorbing the target gas species at high pressure. The process then swings to low pressure to desorb the adsorbed material.
