molekeng wa sebetsa lefatšo la vpsa
VPSA (Vacuum Pressure Swing Adsorption) ho boloka lefatshe ke letsatsi tse pedi le ho hlaboswa ka mabapi a matlhase, ho ya ka lintho tse nang le ho na le oxygen le nitrogen. Lebaka la ho hlaboswa le ile tshepeletseng molecular sieve materials e sebatang nitrogen le ho latela oxygen ho o ne. Siteme sa VPSA se sebatang ka mabapi a mabatsi a mangata, re ho fumana le ho hloka bapeli ba ho hlaboswa ka mabapi a lekgetla, ha ho qala ho hlahloba ka mabapi a lekgetla le ho hloka ho phatlalatsa bapeli ba ho hlaboswa ka mabapi a vacuum. Ho ya ka VPSA ho ile boemo ba oxygen ba 90-95%, e leng maikutlong a matsatsi a mangata. Lebaka le ile dikhotso tse ding tseo tse dirwang adsorbent material, ho sebatang ka letsatsi tse di latelang ho ya ka letsatsi tse di latelang. Lintho tse di latelang tse di latelang tseo di khahlanong ho ya ka: compressor tsa thari, pumpe tsa vacuum, dikhotso tse dirwang adsorbent, le control systems tse pedi tse sebatang cycles tsa pressure swing. Lebaka le ile ho hlokomela ho ya ka gas generation ka letsatsing, ho ile ho ya ka alternative e ntsehelang le reliable ho ya ka cryogenic separation le ho ya ka liquid oxygen delivery. Ho ya ka le ile ho ya ka faelo e mongalo e mongalo, ho ile ho ya ka steel manufacturing, glass production, le water treatment facilities, ho na le oxygen e mongalo e mongalo. Dikhotso tse di latelang VPSA tse di latelang tse di latelang heat recovery systems le advanced control algorithms ho ile ho ya ka ho fihlella performance le ho tshwarelwa mabapi a ho romellana.
