Concerns that the draft revision of the WHO International Pharmacopoeia would restrict access to medical oxygen are resolved. Past uncertainties caused by separate international definitions of medicinal oxygen dependant on concentration are thus eliminated. Healthcare Authorities, Hospitals and Healthcare Professionals working to the PH.INT definition can now treat patients with both oxygen 93% and oxygen 99.5% regardless of source.

As the epidemic swept the world, ventilators gradually entered the public s field of vision, but for those who do not know medical equipment, it is easy to confuse oxygen generators and ventilators, thinking that oxygen generators can also be used as ventilators, but in fact they are not same.

For enterprises that need oxygen long-termly, there are two ways to obtain oxygen gas, one is direct purchase, the another is producing by their own. It is easy to understand the direct purchase, but self-production means that initial investment is required to build an oxygen generation system; In the short term, it is convenient and economical to purchase and use oxygen gas, but if the demand for oxygen is long-term and sustainable, the total cost of direct oxygen procurement may not be cost-ef

At present, the adsorption pressure of VPSA oxygen generator is about 0.05Mpa, which is only less than 1 10 of that of psa oxygen generator, and the gas output of a single machine can reach 7500~9000Nm³ h, which is dozens of times that of psa oxygen generator. The most important thing is that VPSA has lower energy consumption (power consumption per cubic meter of oxygen production ≤ 0.5 kW), and is more environmentally friendly and green.

Strictly speaking, VPSA (low pressure adsorption vacuum desorption) oxygen production is another "variant " of PSA oxygen production. Their oxygen production principles are almost the same, and they all use molecular sieves to "adsorb " different gas molecules to separate gas mixtures, but the PSA oxygen generator separates oxygen through pressure adsorption and atmospheric pressure desorption, while the VPSA oxygen generator desorbs the saturated molecular sieve under vacuum conditions.

In response to this rule, some people have shown the conversion relationship between atmospheric pressure dew point and pressure dew point through calculation and chart. I believe the following table will bring some convenience to the relevant personnel in the compressed air purification industry and the industry using compressed air.

1-Long term stable "oxygen source ".2-The construction and management of oxygen generating station is easy.3- Medical oxygen is used widely

The pressure swing adsorption nitrogen generator (referred to as PSA nitrogen generator) uses two adsorption towers in parallel, and the sequence is strictly controlled by a specific programmable program, and the pressure adsorption and decompression regeneration are alternately performed to complete the air separation and obtain high-purity nitrogen. Since the PSA nitrogen generator is always under pressure during operation, does that mean the adsorption tower should be a pressure vessel?

Medical central oxygen production system is a kind of central oxygen supply. It is simply understood that it consists of two systems: an oxygen production system and an oxygen supply system. The system takes the oxygen production system as the core (which can also be understood as an oxygen source), and distributes oxygen to each bed or gas terminal through the oxygen supply pipeline to meet the oxygen demand of medical technology.

31 May 2022 – The World Health Organization (WHO), in partnership with the King Salman Humanitarian Aid and Relief Centre (KSrelief), will install lifesaving oxygen stations in 5 main hospitals located in priority southern governorates of Hadramout, Shabwa, Marib and Abyan.
