Gasi Wachilengedwe kupita ku Methanol Refinery plant

Zida zopangira methanol zimatha kukhala gasi wachilengedwe, gasi la uvuni wa coke, malasha, mafuta otsalira, naphtha, mpweya wa acetylene mchira kapena mpweya wina wonyansa wokhala ndi hydrogen ndi carbon monoxide.Kuyambira m'ma 1950, mpweya wachilengedwe wakhala pang'onopang'ono kukhala chinthu chachikulu chopangira methanol synthesis.Pakali pano, zoposa 90% ya zomera padziko lapansi zimagwiritsa ntchito gasi ngati zopangira.Chifukwa njira yopangira methanol kuchokera ku gasi ndi yayifupi, ndalama zimakhala zotsika, mtengo wopangira ndi wotsika, komanso kutulutsa zinyalala zitatu kumakhala kochepa.Ndi mphamvu yoyera yomwe iyenera kulimbikitsidwa mwamphamvu.

● Kupulumutsa mphamvu ndi kusunga ndalama.
● Mtundu watsopano wa methanol synthesis tower yokhala ndi mpweya wapakatikati wa methanol umatengedwa kuti uchepetse kugwiritsa ntchito mphamvu.
● Kuphatikizika kwa zida zapamwamba, ntchito yaying'ono pa malo ndi nthawi yochepa yomanga.
● Ukadaulo wopulumutsa mphamvu, monga ukadaulo wa hydrogen recovery, tekinoloji yosinthiratu, ukadaulo wamafuta achilengedwe a gasi ndi ukadaulo wowotcha mpweya woyaka moto, amavomerezedwa kuti achepetse kugwiritsa ntchito methanol.Kupyolera mu njira zosiyanasiyana, mphamvu yogwiritsira ntchito tani imodzi ya methanol imachepetsedwa kuchoka pa 38 ~ 40 GJ kufika pa 29 ~ 33 GJ.

Mpweya wachilengedwe umagwiritsidwa ntchito ngati zopangira, ndiyeno kukakamizidwa, kutsukidwa ndikuyeretsedwa kuti apange ma syngas (makamaka opangidwa ndi H2 ndi CO).Pambuyo psinjika zina, syngas akulowa methanol synthesis nsanja kuti lithe methanol pansi zochita za chothandizira.Pambuyo pa kaphatikizidwe wa crude methanol, kudzera mu pre distillation kuchotsa fusel, rectification kupeza yomalizidwa methanol.
