Used to generate industrial gases onsite, pressure swing adsorption (PSA) plants are an alternative to more traditional cryogenic air separation processes. Considered advantageous when it comes to producing smaller volumes of oxygen, PSA has seen increased uptake over the past two years for medical oxygen production as healthcare facilities across the world look to adopt PSA technology to treat patients suffering from Covid-19.
During the pandemic industrial gas producers in low- and middle-income countries (LMICs) ramped up their medical oxygen production capacity to treat those who required oxygen treatment.
By installing PSA systems at hospitals, countries with low medical oxygen capacities such as India were able to mitigate shortages and supply chain concerns associated with liquid oxygen storage and transport. In doing so, life-saving oxygen was supplied in larger quantities to those who needed it most.
