Molecular sieve dehydration skid

Tsanangudzo

Molecular sieve dehydration skid chinhu chakakosha mukuchenesa gasi rechisikigo kana gasi remusikirwo. Molecular sieve ndeye alkali simbi aluminosilicate crystal ine furemu chimiro uye yunifomu microporous chimiro. Kana gasi rekudya rine mvura yekutsvagisa richipfuura nepamubhedha wekusefa pane tembiricha yekamuri, iyo inoteedzera mvura uye mercaptan inonyudzwa, nekudaro ichidzikisa mvura uye mercaptan zvirimo mugasi rekudyisa, nekuona chinangwa chekubvisa mvura uye desulfurization. iyo adsorption process ye molecular sieve inowanzoitwa pane yakaderera tembiricha uye yakanyanya kudzvanywa, nepo desorption regeneration inoitwa pakupisa kwakanyanya uye kuderera kudzvinyirira. Pasi pekuita kwekupisa kwakanyanya, kwakachena uye kwakaderera kudzvanywa kudzoreredza gasi, iyo molecular sieve adsorbent inoburitsa adsorbate mumicropore mukuyerera kwegasi rekuyerera kudzamara huwandu hweadsorbate mu adsorbent hwasvika padanho rakaderera, uye inokwanisa kutora mvura. uye mercaptan kubva kune gasi rekudya, kuona kuvandudzwa uye kudzokorodza maitiro e molecular sieve.
Molecular sieve nzira imhando yekudzika kwemvura yemvura, iyo inowanzoshandiswa mukudzika-tembiricha condensation kupatsanurwa maitiro, seyakasikwa gasi condensate (NGL) kudzoreredza uye dehydration process mukugadzira liquefied natural gas (LNG). Pamusoro pezvo, ma molecular sieve dehydration inoshandiswawo mukugadzira gasi rakatsikirirwa rechisikigo remafuta emotokari.

Molecular sieve dehydration inowanzoshanda kune zvinotevera zviitiko:
a. Iko uko dova regasi rechisikigo rinodikanwa kuve rakaderera pane -40 ℃.
b. Inokodzera hydrocarbon dovi point control yeakaonda yakakwira kudzvanywa gasi rechisikigo.
c. Gasi rechisikigo rinopera mvura uye rinocheneswa panguva imwe chete.
d. Kana gasi rechisikigo rine H2S rapera mvura uye ranyungudutswa muglycol, rinokonzeresa kubuda kwegasi rekuzvarwa patsva.
e. Kana LPG neNGL kupera simba kwemvura kunoda kubvisa trace sulfide (H2S, CO, COS, CS2, mercaptan) panguva imwe chete.

Flow chati

Fixed bed adsorbers anoshandiswa kune molecular sieve dehydration, saka iyo unit inofanira kunge iine maviri adsorbers, imwe mu adsorption dehydration stage, imwe mukuvandudza uye kutonhora nhanho. Kana huwandu hweyuniti hwakakura kwazvo, iyo multi tower process inogonawo kurongwa.
