To present an inexhaustible provide of oxygen to hospitals, the Council of Scientific and Industrial Research- Indian Institute of Petroleum (CSIR-IIP), Dehradun has developed oxygen enrichments items that may generate as much as 500 litres per minute of medical grade oxygen.
In view of the spike in Covid instances, there was an uncommon rise within the demand for medical oxygen in addition to a steep rise in projections within the anticipated demand for medical oxygen as on April 30 in some states, in line with an announcement from the Union Ministry of well being and household welfare. An inter-ministerial Empowered Group (EG2) of officers beneath the chairmanship of Dr Guruprasad Mohapatra, Secretary, Department for Promotion of Industries and Internal Trade has initiated motion to offer important medical gear, together with medical oxygen, to the affected states.
Director-General, CSIR, Dr Shekhar Mande instructed The Indian Express that they’ve recognized fabricators who could make these items primarily based on the CSIR-IIP design and have additionally invited hospitals to contact them if the latter required such items. “We can go and install the plant through the fabricator at any hospital in the country. It can be IOT enabled. The manpower cost comes down significantly compared to the use of oxygen cylinders and since it IOT enabled, how much medical care oxygen is being produced can be monitored from a remote site – say from the reception of a hospital; the staff can keep monitoring the level of oxygen and if there are fluctuations then company personnel can have a look at it immediately online,” Dr Mande mentioned.
Director, CSIR-IIP, Dr Anjan Ray instructed The Indian Express that air comprises 21 per cent oxygen and there are two standard methods by which hospitals get this oxygen. “In the big hospitals, there are large liquid oxygen plants where tankers bring in the liquid oxygen and this is blown into distributed pipes (manifolds) going to patients. This is expensive to bring and store but easy to distribute. Smaller hospitals have big cylinders and typically for about four patients there may be one cylinder.”
He added: “Using time tested concepts of oxygen concentration by pressure-swing adsorption (PSA) elsewhere in the world, we made an innovation that allows oxygen to be produced more efficiently and cheaply – using pressure vacuum swing adsorption technology (PVSA). The hassle of managing cylinders with manpower disappears and reduces the load of constantly buying cylinders so that we create an essentially inexhaustible oxygen supply chain for each hospital.”
The analysis establishment has tied up with Gaskon engineering firm and is different companions in order that manufacturing might be ramped up.
Dr Swapnil Divekar, principal scientist on the institute, mentioned they began in-house work 4 years in the past however when the pandemic reached an alarming degree they designed the method and in December 2020 arrange an illustration plant. “The earlier work was done at a small scale but it was scaled up later. We installed the demonstration unit and have been rigorously testing the process related to the reliability of the design and plant for the past four months. We have been successful in achieving the purification target through our process,” Dr Divekar mentioned.
