The company's Jamnagar refineries in Gujarat initially produced 100 tonnes of medical-grade oxygen, which has quickly been ramped up to over 700 tonnes, people aware of the matter said. 

 The supplies being made to states like Gujarat, Maharashtra and Madhya Pradesh will provide relief to over 70,000 critically ill patients everyday. The company plans to raise medical-grade oxygen production capacity to 1,000 tonnes, sources said, without giving a timeline. An e-mail sent to the company for comments remained unanswered. Medical-grade oxygen is not a product that was produced at the Jamnagar refineries, which convert crude oil into products such as diesel, petrol and jet fuel.
