Iyo ASU Plant inogadzira Liquid Gasi seanotevera Matanho manomwe:

1.Pamberi pekumanikidza mhepo inofanosefa yeguruva.

2.Mhepo inomanikidzwa uko iyo yekupedzisira dhizaini yekutumira inotarwa nekudzoreredza uye mamiriro emvura (gasi kana mvura) yezvigadzirwa.Madzvinyiriro akajairika anotangira pakati pe5 ne10 bar geji.Kuyerera kwemhepo kunogona zvakare kudzvanywa kune dzakasiyana siyana kuti uwedzere kushanda kweiyo ASU.Panguva yekumanikidza mvura inodzikiswa mukati me-inter-stage coolers.

3.Iyo mhepo yemhepo inowanzopfuura nemubhedha resefa, iyo inobvisa chero yasara mhute yemvura, pamwe nekabhoni dhaokisaidhi, iyo inoomesa nekuvhara iyo cryogenic midziyo.Masefa mamorekuru anowanzo gadzirwa kuti abvise chero gaseous hydrocarbons kubva mumhepo, sezvo izvi zvichigona kuve dambudziko mune inotevera air distillation inogona kukonzera kuputika.Iyo molecular sieves bed inofanira kuvandudzwa.Izvi zvinoitwa nekuisa akawanda mayuniti anoshanda mune alternating modhi uye kushandisa yakaoma coproduced gasi tsvina kuti asvibise mvura.

4.Process mhepo inopfuudzwa kuburikidza neyakasanganiswa kupisa exchanger (kazhinji ndiro yefin heat exchanger) uye yakatonhodzwa ichipikisa chigadzirwa (uye tsvina) cryogenic nzizi.Chikamu chemhepo chinonyunguduka kuita mvura inowedzerwa muokisijeni.Iyo gasi yasara yakapfuma munitrogen uye inonyungudutswa kusvika kuine nitrogen yakachena (kazhinji <1ppm) mune yakakwira pressure (HP) distillation column.Iyo condenser yekoramu iyi inoda firiji iyo inowanikwa kubva pakuwedzera iyo yakawanda oksijeni yakapfuma rukova mberi nepakati pevharuvhu kana kuburikidza neExpander, (reverse compressor).

5 Neimwe nzira iyo condenser inogona kutonhodzwa nekuchinjanisa kupisa nere boiler mune yakaderera pressure (LP) distillation column (inoshanda pa1.21.3 bar abs. ) apo ASU iri kuburitsa okisijeni yakachena.Kuti uderedze mutengo wekumanikidza yakasanganiswa condenser/reboiler yeHP/LP makoramu inofanirwa kushanda netembiricha musiyano we1-2 madhigirii Kelvin chete, inoda ndiro fin brazed aluminum heat exchangers.Yakajairika oksijeni yakachena inotangira kubva ku97.5% kusvika 99.5% uye inokanganisa kupora kwakanyanya kweokisijeni.Iyo firiji inodiwa pakugadzira zvigadzirwa zvemvura inowanikwa uchishandisa iyo JT mhedzisiro mune expander iyo inodyisa mweya wakamanikidzwa zvakananga kune yakaderera pressure column.Nokudaro, imwe nzvimbo yemhepo haifaniri kupatsanurwa uye inofanira kusiya mbiru yakaderera semarara kubva kune chikamu chayo chepamusoro.

6 Nokuti nzvimbo yekuvira yeargon (87.3 K pamamiriro ezvinhu akaenzana) iri pakati peiyo yeokisijeni (90.2 K) uye nitrogen (77.4 K), argon inovaka muchikamu chezasi chekoramu yakaderera.Kana argon inogadzirwa, mhute yedivi dhizaini inotorwa kubva kune yakaderera kudzvanywa

Column uko iyo argon concentration yakanyanya.Inotumirwa kune imwe koramu inogadzirisa Argon kune yaunoda kuchena kubva iyo mvura inodzoserwa kunzvimbo imwechete muLP column.Kushandiswa kwemazuva ano akarongedzerwa packing ane akanyanya kuderera kudonhedza anodonha anogonesa argon kucheneswa kweisingasviki 1 ppm.Kunyangwe argon iripo mune isingasviki 1% yeinouya, iyo air argon column inoda huwandu hwakakura hwesimba nekuda kweiyo reflux reshiyo yakakura inodiwa (inenge makumi matatu) muArgon column.Kutonhora kweiyo argon column kunogona kupihwa kubva kunotonhora yakawedzera yakapfuma mvura kana neiyo nitrogen yemvura.

7 Pakupedzisira zvigadzirwa zvinogadzirwa muchimiro chegasi zvinodziirwa kubva kumhepo iri kuuya kusvika kune tembiricha yepakati.Izvi zvinoda kunyatsogadzirwa kusanganisa kupisa kunofanirwa kubvumira kusimba kunopesana nekukanganisika (nekuda kwekuchinja pamusoro pemabhedha sieve).Inogonawo kuda kuwedzera kunze firiji panguva yekutanga-up.
