Natural Gasi kuMethanol Refinery chirimwa

Zvigadzirwa zvekugadzira methanol zvinogona kuve gasi rechisikigo, coke oven gasi, marasha, mafuta akasara, naphtha, acetylene muswe gasi kana imwe tsvina gasi ine hydrogen uye kabhoni monoxide.Kubva kuma1950, gasi rechisikigo rave zvishoma nezvishoma rave chinhu chikuru chekugadzira methanol synthesis.Parizvino, zvinopfuura 90% zvezvirimwa zviri munyika zvinoshandisa gasi rechisikigo sechinhu chisina kubikwa.Nekuti mafambiro ekugadzirwa kwemethanol kubva kugasi chaiwo ipfupi, mari yekudyara yakaderera, mutengo wekugadzira wakaderera, uye kubuda kwemarara matatu kushoma.Isimba rakachena rinofanira kusimudzirwa nesimba.

● Kuchengetedza magetsi uye kuchengetedza mari.
● Rudzi rutsva rwemethanol synthesis tower ne-product medium pressure steam inogamuchirwa kuderedza kushandiswa kwesimba.
● Kubatanidzwa kwezvigadzirwa zvepamusoro, zviduku pa-site basa uye nguva pfupi yekuvaka.
● Unyanzvi hwekuchengetedza magetsi, hwakadai sehydrogen recovery technology, pre conversion technology, natural gas saturation teknolojia uye combustion air preheating teknolojia, inogamuchirwa kuderedza kushandiswa kwemethanol.Kuburikidza nezviyero zvakasiyana-siyana, kushandiswa kwesimba patani yemethanol kunoderedzwa kubva pa38 ~ 40 GJ kusvika pa29 ~ 33 GJ.

Gasi remusikirwo rinoshandiswa seyakagadzirwa, yobva yamanikidzwa, yakasvibiswa uye yakacheneswa kugadzira syngas (inonyanya kuumbwa neH2 neCO).Mushure mekuwedzera kudzvanywa, iyo syngas inopinda mu methanol synthesis tower kuti igadzire methanol pasi pechiito checatalyst.Mushure mekugadzirwa kwe crude methanol, kuburikidza nepre distillation kubvisa fusel, kugadzirisa kuwana methanol yapera.
