Kayan aiki na gas na tsarin kimika | Mabukun tsarin mabukun da ke cikin kofin da ke damuwa ga wani abu

Bayanin

Tsarin fuskantar gas na gida ta hanyar tsarin hawa don samun syngas:

An kwayar kwayar kyau ta halitta zuwa tsawon 3.5 MPa, sannan ta fito daga kwayar zaiki zuwa tsawon ≤0.1 ppm, kuma ta rage da abubuwan ruwa a cikin nisbi na molar na 3.5. Sannan shiga gona mai karfama mai amfani da ruwa, inda methane yana canza a tsawon 800–900°C kuma 2–3 MPa akan catalyst na nickel, kuma yana samar da nisbi na canji na methane ≥95%. Samar da syngas tare da nisbi na H₂/CO ta takamata 3.0, tare da amfanin hankali ≤27 GJ kowane ton na ammonia.

Tsarin samun hydrogen daga syngas:

Syngas ke tafiye canje-canjen tsawon mitadin mitadi don canja CO zuwa H₂ da CO₂, sannan saboda amfani da tasowa ta hanyar pressure swing adsorption (PSA) don samar da haidrogen tare da sahihuwa ≥99.99% kuma nisbi na jagora ≥85%. Gas mai natsaro ana koma shi har ma gona mai karfafa yayin zai yi wajen kuwa, kuma haidrogen ana bawa shi wajen hydrogen refueling stations ko wasu ayyukan iko.

Tsarin samun ammonia mai kariya daga syngas:

An samawa syngas din gurji take da nitrogen daga tashewar abubuwa a sama ta hanyar yadda H₂/N₂ ke da wuri ne na 3.0, sannan kuma an kunna shi zuwa 14–16 MPa, kuma an bawa shi cikin takalmamin tsarin amonia na radial. Anke tsara amonia a kan catalyst na iron a tsakiyar dare 400–450°C, tare da yawan girma na ≥18%. An samu albarkatu baƙin amonia bayan tashewar sauke sauƙi.

Bayani na Tsarin Syngas zuwa Methanol:

An kunna syngas zuwa 5–8 MPa kuma an tsara shi cikin methanol marasa kyau ta hanyar catalyst na copper a tsakiyar dare 220–260°C. Harshen rashin yawa yana hada 2.5 MPa steam kamar natsuwa. An samu methanol mai inganci na AA ta hanyar tashewar uku, tare da kewayon kewayon matakan ≤28 GJ per ton of methanol kuma yawan harshen catalyst ≥3 shekara.

Wakati na Tsara, Raba, da Kafa:

Takaingin hanyar fitarwa, abubuwan kayan aiki masu mahimmanci kamar kofinar sadafa da takalmaman tsaro sun fitar da su a wurin kamfanin kuma sun kama a wurin. Jimlar lokacin ayyukan daga lokacin signatura na hawun zuwa rarrabuwa shine 10–12 watansa.
