Yakakwira Hunhu China Fuel Gasi Conditioning Solution Mafekitori - MDEA desulphurization skid yekurapa gasi rechisikigo - Rongteng

Tsanangudzo

MDEA desulphurization (desulfurization) skid, inonziwo MDEA sweeting skid, chishandiso chakakosha mukuchenesa gasi rechisikigo kana gasi remusikirwo.

MDEA desulfurization skid yegasi rechisikigo inogara ichigamuchirwa kana kabhoni sulfur yefeed gasi yakakwira, uye kana kusarudzwa kubviswa kweH2S kunodiwa kuti uwane asidi gasi rakakodzera Claus plant processing, uye mamwe mamiriro anogona kusarudzwa kubvisa H2S; Paunenge uchibvisa H2S uye uchibvisa huwandu hwakawanda hweCO2, MDEA uye imwe alcoholamine (yakadai seDEA) inogona kushandiswa seyakasanganiswa amine nzira;

Process

Mushure mekunge tsvina yakasimba uye yemvura yabviswa kubva mugasi rekudyisa kuburikidza nemuparadzanisa uye separator, gasi rekudyisa rinosvibiswa mushongwe yevharuvhu. Methyl diethanol (MDEA) mhinduro inoshandiswa se desulphurizer mushongwe.

Mushure mekubvisa hushoma hweMDEA furo remvura kubva gasi kuburikidza neyakanyorovesa yekuchenesa gasi, rakanyorova gasi rinopinda mushongwe yekubvisa mvura.

TEG inoshandiswa kudzikisa mvura yakanyorova gasi rechisikigo mushongwe uye gasi rakaoma kubva pashongwe yekupera mvura inoshandiswa. Gasi remusikirwo rinoshandiswa segasi remhando yepamusoro kutengeswa kunze kwenyika.

Iyo MDEA yakapfuma mvura iri mushongwe yedesulfurization inopenya evaporated kubvisa mahydrocarbon uye kusefa nemasefa. Zvadaro zvinopiswa nemhepo kuti igadzirise hurombo hweMDEA mvura, iyo inoputirwa kune desulfurization tower ye cyclic desulfurization.

Iro gasi rechisikigo kubva kuMDEA rakapfuma mvura flash inobviswa neasidhi-mvura yekuparadzanisa, uye iyo yakaparadzaniswa yeMDEA mhinduro inopomberwa kune desulfurization tower. TEG yakapfuma mvura inoshandiswa mu dehydration tower inodziya kuti igadzirise hurombo TEG mhinduro kuburikidza ne distillation column, flash tank uye sefa. Iyo inoputirwa kune dehydration tower ye cyclic dehydration.

Mushure mekubaya H2S gasi muasidhi gasi rekuchengetera tangi panzvimbo yekuparadzana yeasidhi mvura yekuparadzanisa, inofanopiswa muvira rekuita uye inosvetwa nemhepo yakasvetwa nemhepo compressor kuumba SO2, iyo inopindirana neH2S yasara kuumba elemental sulfur, yozowana sulfur mushure mekutonhora.
