Tlhaloso

Molecular sieve dehydration skid ke sesebelisoa se ka sehloohong sa tlhoekiso ea khase ea tlhaho kapa ho lokisa khase ea tlhaho. Sieve ea molek'hule ke kristale ea alkali ea tšepe ea aluminosilicate e nang le sebopeho sa moralo le sebopeho sa microporous se ts'oanang. Ha khase ea phepelo e nang le metsi a marang-rang e feta ka har'a bethe ea sieve ea molek'hule ka mocheso oa kamore, metsi a trace le mercaptan a kenngoa, kahoo a fokotsa metsi le mercaptan ka har'a khase ea phepelo, ho lemoha morero oa ho felloa ke metsi le ho senya metsi. mokhoa oa adsorption oa sieve ea molek'hule hangata o etsoa ka mocheso o tlase le khatello e phahameng, ha ho tsosolosoa ha desorption ho etsoa ka mocheso o phahameng le khatello e tlaase. Tlas'a ketso ea mocheso o phahameng, khase e hloekileng le e tlase ea khatello ea khatello, molek'hule sieve adsorbent e lokolla adsorbate ka har'a micropore ho phallo ea khase e nchafatsang ho fihlela palo ea adsorbent e fihla boemong bo tlase haholo, 'me e na le bokhoni ba ho monya metsi le mercaptan ho tsoa khase ea phepelo, ho hlokomela ts'ebetso ea ho nchafatsa limolek'hule.
Mokhoa oa sieve ea molek'hule ke mofuta oa mokhoa o tebileng oa ho felloa ke metsi 'meleng, oo hangata o sebelisoang ts'ebetsong ea karohano ea mocheso o tlase oa condensation, joalo ka khase ea tlhaho ea condensate (NGL) ea ho hlaphoheloa le ts'ebetso ea ho felloa ke metsi ha ho etsoa tlhahiso ea khase ea tlhaho ea liquefied (LNG). Ho feta moo, ho felloa ke metsi ka molek'hule ho boetse ho sebelisoa tlhahiso ea khase ea tlhaho e hatelitsoeng bakeng sa mafura a koloi.

Molecular sieve dehydration hangata e sebetsa liketsahalong tse latelang:
a. Moo phoka ea khase ea tlhaho e hlokahalang ho ba ka tlase ho -40 ℃.
b. E loketse taolo ea phoka ea hydrocarbon ea khase ea tlhaho ea khatello e phahameng.
c. Khase ea tlhaho e felloa ke metsi 'me e hloekisoa ka nako e le' ngoe.
d. Ha khase ea tlhaho e nang le H2S e felloa ke metsi 'me e qhibiliha ka glycol, e tla baka ho tsoa ha khase ea tsosoloso.
e. Ha LPG le NGL dehydration li hloka ho tlosa trace sulfide (H2S, CO
COS, CS2, mercaptan) ka nako e le 'ngoe.

Phallo chate

Li-adsorbers tse tsitsitseng tsa bethe li sebelisetsoa ho felloa ke metsi ka molek'hule, kahoo yuniti e lokela ho ba le bonyane li-adsorbers tse peli, e 'ngoe e le sethaleng sa ho ntša metsi, e' ngoe e le boemong ba ho tsosolosa le ho pholile. Ha bokhoni ba yuniti bo le boholo haholo, ts'ebetso ea litora tse ngata le tsona li ka hlophisoa.
