A company is daily providing southern Vietnam with hundreds of oxygen cylinders as Covid-19 cases soar across the region.
Messer Vietnam Industrial Gases in central Quang Ngai Province, one of the two largest industrial gas production facilities in Vietnam, boasts a capacity of nearly 100 tons per day.Producing medical oxygen occurs within a closed chain. After entering a filter layer, the air passes through a cooling system where impurities are removed before it is deeply cooled, and fed into the gas separation tower. In this tower, gases are separated according to the distillation principle to separate oxygen, nitrogen or argon. Photo by Messer Vietnam.

Tankers carrying liquefied oxygen gather at a gas extraction plant of Messer in Thuan An Town of Binh Duong Province that borders Ho Chi Minh City on July 22. When in use, liquefied gas inside the tanks will be vaporized and pumped into compressed air bottles for consumption.

Messer is one of the largest oxygen manufacturers in the south, supplying medical facilities in Binh Duong, HCMC, Long An, Tien Giang and Can Tho, among others. The firm is also expected to install large oxygen tanks at hospitals and ICUs intended for Covid-19 treatment.Previously, the health ministry repeatedly assured oxygen production capacity in Vietnam could still meet domestic demand. It warned citizens against hoarding ventilators and oxygen tanks as that may cause shortages and prevent access for those who need them most.
