MDEA desulphurization (desulfurization) skid, eo hape e bitsoang MDEA sweeting skid, ke sesebelisoa sa mantlha sa tlhoekiso ea khase ea tlhaho kapa ho lokisa khase ea tlhaho.

MDEA desulfurization skid bakeng sa khase ea tlhaho e lula e amoheloa ha carbon sebabole ea khase ea phepelo e batla e phahame , 'me ha ho khethoa ho tlosoa ha H2S ho hlokahala ho fumana khase ea acid e loketseng ho sebetsa ha limela tsa Claus, le maemo a mang a ka khethoang ho tlosa H2S; Ha o tlosa H2S le ho tlosa palo e kholo ea CO2, MDEA le alcoholamine e meng (e kang DEA) e ka sebelisoa e le mokhoa o tsoakiloeng oa amine;

Ka mor'a hore litšila tse tiileng le tse nang le metsi li tlosoe khase ea phepelo ka karohano le karohano ea filthara, khase ea phepelo e tlosoa sulphurized tora ea valve ea float. Tharollo ea Methyl diethanol (MDEA) e sebelisoa e le desulphurizer tora.

Kamora ho tlosa foam e nyane ea mokelikeli oa MDEA ho tsoa khase ka karohano ea tlhoekiso e metsi, khase ea tlhaho e metsi e kena tora ea ho felloa ke metsi.

TEG e sebelisetsoa ho ntša metsi ka har'a khase ea tlhaho e metsi ka tora 'me khase e omeletseng e tsoang tora ea ho ntša metsi e sebelisoa. Khase ea tlhaho e sebelisoa e le khase ea thepa e tšoanelehang bakeng sa ho romelloa kantle ho naha.

Mokelikeli o nonneng oa MDEA toreng ea desulfurization o fetoha mouoane ho tlosa li-hydrocarbon ebe o sefuoa ka li-filters. Ebe e futhumatsoa ke mouoane ho hlahisa metsi a fokolang a MDEA, a pompeloang toreng ea desulfurization bakeng sa cyclic desulfurization.

Khase ea tlhaho e tsoang ho MDEA e nang le mokelikeli o mongata o tsoang ho MDEA e tlosoa ka separator ea acid-metsi, 'me tharollo ea MDEA e arohaneng e pompeloa toreng ea desulfurization. Mokelikeli o mongata oa TEG o sebelisoang toreng ea dehydration o futhumatsoa ho nchafatsa tharollo ea TEG e mpe ka kholomo ea distillation, tanka ea flash le sefa. E pompeloa toreng ea dehydration bakeng sa dehydration ea cyclic.

Ka mor'a ho kenya khase ea H2S ka har'a tanka ea ho boloka khase ea asiti sebakeng sa karohano ea karohano ea metsi a asiti, e chesoa pele ka sebōping sa karabelo 'me e arabela ka moea o monngoang ke konpresser ea moea ho theha SO2, e sebetsanang le H2S e setseng ho theha sebabole sa motheo, ebe o fumana sebabole ka mor'a ho pholile.
