tsawwo daidai na shirye
Takaddun Vacuum Pressure Swing Adsorption (VPSA) ya same kasar rubutu suna daidai a cikin wani shugaban kwayoyin rubutu, an yi amfani daidai naɗan da karfi da hanyar sauka rubutu mai tsallabarsa. Takaddunin gaba na yanzu suna iya tambaya da hanyar masu taimako molecular sieve materials don sama suka samun nitrogen daga ƙasa taɓbatar gudanarwa sabon wata da rubutu suna iya fiye. Kwayoyin na yanzu suna iya yi biyu hakuri: pressurization da vacuum desorption, suka samu a kan kushe-kushe don samun rubutu daidai. A cika wannan amfani, ƙasa taɓbatar gudanarwa suna iya samuwa da yayi fiye a cikin vessels dai dai dai da molecular sieve beds, saboda wannan sabon nitrogen molecules suna iya sama sabon rubutu molecules suna iya fiye. Takaddunin na yanzu suna iya samuwa a cikin wannan vacuum phase don regenerat sieve material, don sake samun wannan hakuri. Takaddunan VPSA modern suna iya samun rubutu purity levels up to 95%, don binciken suna iya yi amfani daidai a cikin biyu industrial, medical, da commercial applications. Takaddunin na yanzu suna iya tambayawa da adjust operational parameters a cikin real time, don samun output quality da optimal energy efficiency. Wannan takaddunin self-contained suna iya same maintenance saboda, suna iya yi amfani daidai a matsayin traditional oxygen supply methods, domin kuma operation costs da reliability.
