Kounga High China Natural Gas Tukatuka Unit wheketere - Molecular sieve desulphurization skid – Rongteng

Tikanga

Ko te molecular sieve desulphurization (desulfurization) skid, e kiia ana ko te molecular sieve sweeting skid, he taputapu matua i roto i te pure hau maori, te whakamahana hau maori ranei. Ko te tatari molecular he karaihe aluminosilicate whakarewa alkali me te hanganga anga me te hanganga microporous rite. I te wa e haere ana te hau kai kei roto i te wai tohu i roto i te moenga tatari ngota i te pāmahana rūma, ka uru te wai me te mercaptan, na reira ka whakaiti i te wai me te ihirangi mercaptan i roto i te hau whangai, ka mohio ki te kaupapa o te whakamakuku me te whakaheke. Ko te tukanga adsorption o te tatari rāpoi ko te condensation capillary me te adsorption tinana na te kaha o van der Waals. Mai i te whārite Kelvin, ka kitea te ngoikore o te condensation capillary i te pikinga o te pāmahana, i te mea ko te adsorption tinana he tukanga exothermic, a ka ngoikore tona adsorption ki te piki o te pāmahana me te piki ake i te piki o te pehanga; no reira, ko te tukanga adsorption o te tatari molecular i te nuinga o te waa ka mahia i te iti o te pāmahana me te pehanga teitei, i te wa e mahia ana te whakahoutanga o te desorption i te pāmahana teitei me te iti o te pehanga. I raro i te mahi o te pāmahana teitei, te ma me te iti te pehanga regeneration hau, te adsorbent tatari rāpoi tuku i te adsorbate i roto i te micropore ki te rere hau whakaora tae noa ki te nui o te adsorbate i roto i te adsorbent tae ki te taumata tino iti, me te whai i te kaha ki te mimiti wai me te mercaptan i te hau kai, te mohio ki te whakahou me te hangarua tukanga o te molecular.

Te tukanga hangarau

Kei te hoahoa te rere o te rerenga ngota ngota hau maori (desulfurization) mokowhiti. Ko te waeine e tango ana i nga tikanga pourewa e toru, kotahi te whakaurunga o te pourewa, kotahi te whakahoutanga o te pourewa me te whakamahana pourewa. I muri i te tango i te wai waiwaro entrained i roto i te kai whakawehe tātari hau, ka tomo te hau kai ki te pourewa desulfurization tatari rāpoi. Ko te wai me te mercaptan i roto i te hau kai ka uruhia e te tatari ngota kia mohio ai te matewai me te mercaptan adsorption. Ko te hau parakore mai i te matewai me te tango mercaptan ka uru ki te tātari puehu hau hua ki te tango i te puehu tatari ngota, katahi ka kaweake hei hau hua.

Ko nga tatari molecular me whakahou ano i muri i te whakauru i te nui o te wai me te mercaptan. Whai muri i te tātari i te puehu hau hua, ka tangohia tetahi wahi o te hau hua hei hau whakaora. I muri i te whakamahana o te hau ki te 300 ℃ e te oumu whakawera, ka whakawerahia te pourewa ki te 272 ℃ na roto i te molecular sieve desulfurization pourewa kua oti te tukanga adsorption mai i raro ki runga, kia taea ai te wehe i te wai me te mercaptan i runga i te tatari rapoi ki te whakaoti i te tukanga whakaora hou.
