Incazelo

Ukuphatha umoya wezindawo zokusebenza ngokusebenzisa i-steam ukuproducisa i-syngas: Incazelo yeprosesi:

Igasi elihlaza lincomprimwa ku-3.5 MPa, lincaziswa kahle ku-≤0.1 ppm, bese liphindaphindwa nesitimela sezakameli ngomkhawulo we-molar wa 3.5. Emuva koko lubuyela efenyini lokusabalalisa isitimela, lapho umethani usabalaliswa emva kwesikhathi esigcweleyo phakathi kuka-800–900°C kanye no-2–3 MPa kumkakhulu wane-kheniki, ukufika kumehluko wemethani ≥95%. Kukhishwa igasi le-hydrogen/CO engu-3.0, nokunyathelwa kwezimali ≤27 GJ ngayiton ye-ammonia.

Ukuphatha i-syngas ukuze kwenziwe i-hydrogen: Incazelo yeprosesi:

Isitimela sihambisana nesikhathi esiphakade sokuguquka komthwalo, ukuguqula i-CO ku-H₂ kanye no-CO₂, emuva koko kusabalaliswa ngokuthuthulwa okushintshayo (PSA) ukuze kutholakale ihydrogen enenhlaka ≥99.99% kanye nokutholakala kokuphumula ≥85%. Igasi elitholakala litholakala futhi livalelwe emuva efenyini lokusabalalisa njengendiza, kanti ihydrogen inikwa kangaphandle ezinkundleni zokugcwalisa hydrogen noma ezinhlotsheni.

Inkulumo yokuphatha kwe-Syngas ku-Ammonia esithile:

I-syngas esiqinisiweyi isaniselwa kwi-nitrogen ekusungulweni kwamayeza ngemlinganiso we-H₂/N₂ ye-3.0, ishushunyelwa ku-14–16 MPa, bese isuselwa kwi-tower yokwakha kwe-radial ammonia. I-ammonia iyakhiwa phantsi kwe-catalyst ebasisisele ku-iron kuma-400–450°C, ngesilinganiso sokuguqulwa ngokuphambene ≥18%. I-liquid ammonia itholakala emva kokuqeda kusungulwa.

Inkulumo yokuphatha kwe-Syngas ku-Methanol:

I-syngas ishushunyelwa ku-5–8 MPa ibhaxwe kwi-methanol engaphucayi ngapha kwe-catalyst ebasisisele ku-copper kuma-220–260°C. Umthwalo wokureba uphumelela i-steam ye-2.5 MPa njengento engeyiyo. I-methanol eqinisiweyo ye-AA ihlanganiswa ngokwahlulwa kwiintaba ezintathu, nesidingo sokusebenzisa amandla ≤28 GJ ngasinye isithombe se-methanol kwaye ubomi be-catalyst ≥iminyaka engu-3.

Isikhathi sokuphakha, ukufaka, nokuvumela:

Usebenzisa umkhondo othile, izixhobo eziphambili njenge-reforming furnaces ne-synthesis towers zibekwa ngaphambi kwindawo yesiko bese zilungiswe endaweni. Ixesha elipheleleyo leprojekthi ukusuka kumkhuba wokuthengisa ukuya kumkhuba ongcono lizakwenzeka ngu-10–12 iinyanga.
