VPSA oxygen generator

VPSA Oxygen Equipment Main technical parameterFloor area 600m2 Oxygen flow 3000Nm3/Hr Oxygen purity 95% Oxygen pressure 1.2Mpa Oxygen generation power consumption 0.40±10%KWH/Nm2 Installed capacity 6/10KV, 50HZ, 30:355KW×6+280KW×3 2.PSA Process and control descriptions VPSA oxygen generating system consists of blower, vacuum pump, switching valve, and oxygen absorber composition of the buffer tank. Raw materials through the air intake filters remove dust particles, has been to Roots blower supercharger in which an adsorption 0.45barg to enter inside. Adsorbent adsorption inside filling, in which water, carbon dioxide, and a small amount of other gas components in the absorber at the bottom of the entrance was filled with activated alumina by adsorption, then nitrogen was filled in the upper part of activated alumina adsorption by zeolites. The oxygen (including argon gas) non-adsorbed components from the absorber at the top of the exit of the exhaust to oxygen as a product buffer tank. When the absorber adsorption to some extent, one of the adsorbent will be saturated, this time by switching valve, the first after a pressure step-down process were, to the adsorption tower some dead space, oxygen recovery, while the adsorption tower pressure drop to micro-negative pressure, and then carried out using vacuum pump on the vacuum (and adsorption in the opposite direction) and vacuum-0.50barg. Adsorbed water, carbon dioxide, nitrogen and other gas components to be extracted a small amount of side by side to the atmosphere, adsorbent are regenerated.
