Oil & Gas Public Sector Undertaking (PSU) companies, under the administrative control of the Ministry of Petroleum and Natural Gas, Government of India, are planning to set up 100 Pressure Swing Absorption (PSA) Liquid Medical Oxygen (LMO) plants in hospitals pan-India.

Under the guidance of the Minister of Petroleum and Natural Gas Dharmendra Pradhan, the Oil & Gas PSUs are setting up about 100 Pressure Swing Adsorption (PSA) Liquid Medical Oxygen generation plants in public health facilities across the country.

PSA LMO plants will be set up in the states of Uttar Pradesh, Bihar, Karnataka, Goa, Kerala, Maharashtra, Gujarat, Rajasthan, Odisha, Madhya Pradesh and Delhi. The entire expenditure for these plants will be borne by Oil & Gas PSU companies from their CSR (Corporate Social Responsibility) fund.  

These PSA plants will come in varying capacities to generate oxygen which will cater to hospitals with 200 to 500 beds. The Oil & Gas companies will employ technology provided by DRDO and CSIR, absorbing nitrogen from ambient air to concentrate oxygen.

The oxygen thus generated will be supplied straight to patients admitted in the hospital. Orders have been placed with the Indian vendors for these plants, and these will start becoming operational from May and by July all plants will be operational.
