High Quality China LNG Plant Skid Exporters - 134~200 TPD LNG liquefaction plant - Rongteng

Kufotokozera kwa dongosolo lililonse

Kudyetsa gasi kusefera kulekanitsa ndi pressure regulating unit

1) Kufotokozera za ndondomeko

Mpweya wachilengedwe wa chakudya wochokera kumtunda umayenda mupaipi mothamanga kwa 5.0 ~ 6.0MpaG umalowa mu cholekanitsa chopatulira cholumikizira mpweya pambuyo powongolera kukakamiza, ndikulowa mumtsinje wapansi pambuyo pa kulekana ndi kuyeza.

Waukulu ndondomeko zida ndi chakudya mpweya fyuluta olekanitsa, flowmeter, kuthamanga regulator, etc.

2）Pangani magawo

Processing mphamvu: 20 × 10⁴Nm³/tsiku

Kusintha osiyanasiyana: 50% ~ 110%

Pretreatment system

Feed gasi deacidification unit

1) Kufotokozera za ndondomeko

Mpweya wopatsa chakudya wochokera kumtunda umalowa mu gasi wa deacidification, womwe umagwiritsa ntchito njira ya MDEA kuchotsa mpweya wa asidi monga CO.₂ndi H₂S mu gasi chakudya.

Mpweya wachilengedwe umalowa kuchokera kumunsi kwa chotengera (nsanja yoyamwitsa) ndikudutsa mu chotengera kuchokera pansi kupita pamwamba; Njira yothetsera vutoli ya MDEA (yowonda) imalowa kuchokera kumtunda kwa chotsitsa ndikudutsa muzitsulo kuchokera pamwamba mpaka pansi. The reverse flow MDEA yankho ndi gasi wachilengedwe amalumikizidwa kwathunthu mu absorber, CO₂mu gasi amatengeka ndikulowa mu gawo lamadzimadzi, ndipo zigawo zosagwiritsidwa ntchito zimatsogozedwa kuchokera pamwamba pa chotsitsa ndikulowa mu mpweya wozizira wa decarbonization ndi wolekanitsa. Mpweya wochokera pa cholekanitsa mpweya wa decarbonization umalowa mu gawo lochotsa mpweya wa mercury, ndipo condensate imapita ku thanki yamoto.

Malingaliro a kampani CO₂mu mankhwala gasi ndi zosakwana 50ppmv.

The MDEA solution absorbing CO₂amatchedwa wolemera njira, amene anatumizidwa ku flash tower, ndi gasi wachilengedwe unawalira ndi depressurization amatumizidwa ku dongosolo mafuta. Pambuyo pakusinthana kwa kutentha pakati pa madzi ochulukirapo ndi yankho (madzi owonda) otuluka pansi pa nsanja yosinthika, kwezani kutentha mpaka ~ 98 ℃ mpaka kumtunda kwa nsanja yosinthika, ndikuchotsanso kukonzanso mu nsanja yosinthika mpaka digiri yowonda yamadzimadzi yowonda ifika pa index.

Madzi owonda ochokera munsanja yosinthika amadutsa muchotenthetsera chamadzi cholemera ndi chosauka komanso chozizira chamadzimadzi chowonda. Madzi owondawo amakhazikika mpaka ~ 40 ℃, kukakamizidwa ndi pampu yamadzimadzi yowonda ndikulowa kuchokera kumtunda kwa nsanja yoyamwitsa.

Mpweya wotuluka pamwamba pa nsanja yosinthiranso umalowa mu cholekanitsa cha asidi wa asidi kudzera mu choziziritsa mpweya wa asidi, mpweya wochokera ku cholekanitsa cha asidi umatumizidwa ku dongosolo lotulutsa mpweya wa asidi, ndipo condensate imatumizidwa ku cholekanitsa kung'anima pambuyo popanikizidwa ndi mpope wobwezeretsa.

Gwero la kutentha kwa reboiler ya regeneration Tower limatenthedwa ndi mafuta otengera kutentha. Zida zazikuluzikulu za chipangizochi ndi nsanja yoyamwitsa ndi nsanja yosinthira.
