1, mhedzisiro yehuwandu hwakawanda hwemvura pabasa remamorekuru rekusefa
Basa guru remuchina wekuparadzanisa mhepo nderekubvisa hunyoro nehuwandu hwehydrocarbon mumhepo kuti ipe mhepo yakaoma kune mamwe masisitimu anotevera. Chimiro chemidziyo chiri muchimiro chemubhedha wemubhedha wakarara, kureba kwekuzadza kwealumina yakabatidzwa kwepasi i590 mm, kureba kwekuzadza kwe13X molecular sieve ye962 mm, uye kuchenesa kaviri kunochinjirwa pakati peumwe neumwe. Pakati pazvo, alumina yakabatidzwa inonyanya kunyudza mvura mumhepo, uye molecular sieve inoshandisa musimboti wayo wekusarudza adsorption kuti inyudze mahydrocarbon. Zvichienderana nekuumbwa kwezvinhu uye hunhu hweadsorption yemolecular sieve, adsorption order ndeiyi: H2O> H2S> NH3> SO2 > CO2(kurongeka kwekunyudza magasi ealkaline). H2O> C3H6> C2H2> C2H4, CO2, C3H8> C2H6> CH4(kurongeka kwekunyudza mahydrocarbon). Zvinogona kuonekwa kuti ine simba rakasimba rekunyudza mamorekuru emvura. Zvisinei, huwandu hwemvura mu molecular sefa hwakanyanya, uye mvura yakasununguka inoumba crystallization yemvura ne molecular sefa. Tembiricha (220 °C) inopihwa ne 2.5MPa steam inoshandiswa pakugadzirisa tembiricha yepamusoro haigone kubvisa chikamu ichi chemvura yekristaro, uye saizi yepore ye molecular sefa inogarwa nema crystal water molecules, saka haigone kuramba ichinyudza mahydrocarbons. Nekuda kweizvozvo, molecular sefa inodzimwa, hupenyu hwebasa hunopfupikiswa, uye mamorekuru emvura anopinda mu low-pressure plate heat exchanger ye rectification system, zvichiita kuti flow channel ye heat exchanger iome uye ivhare, zvichikanganisa airflow channel uye heat transfer effect ye heat exchanger, uye mune zviitiko zvakakomba, mudziyo haugone kushanda zvakanaka.
2. Mhedzisiro yeH2S neSO2 pabasa remamorekuru
Nekuda kwekusveta kwakasarudzwa kwesefa yemamorekuru, pamusoro pekusveta kwakawanda kwemamorekuru emvura, kusimba kwayo kweH2S neSO2 kuri naniwo pane kushanda kwayo kwesefa yeCO2. H2S neSO2 zvinogara pamusoro pesefa yemamorekuru, uye zvikamu zvine acidic zvinosangana nesefa yemamorekuru, izvo zvinoita kuti sefa yemamorekuru ive nehupfu uye irege kushanda, uye kugona kwesefa yemamorekuru kunoderera. Hupenyu hwesefa yemamorekuru hunopfupikiswa.
Muchidimbu, huwandu hwakawanda hwehunyoro, huwandu hweH2S neSO2 gasi mumhepo inobuda yemhepo inotonhorera shongwe ndiyo chikonzero chikuru chekusashanda kwemolecular sefa uye kupfupisa hupenyu hwebasa. Kuburikidza nekudzora kwakasimba kwezviratidzo zvemaitiro, kuwedzerwa kwepurifier outlet moisture analyzer, kusarudzwa kwakaringana kwemhando dzefungicide, chiyero chefungicide panguva yakakodzera, shongwe yekutonhodza mvura kuti iwedzere mvura isina kubikwa, kuongororwa nguva dzose kwekubuda kweheat exchanger nezvimwe zviyero, kushanda kwakachengeteka uye kwakasimba kwemuchina wekuchenesa kunogona kuita kuti pave nekuona panguva yakakodzera, yambiro nenguva, zvinangwa zvekugadzirisa nenguva, zvakanyanya kuve nechokwadi chekushandiswa kwemolecular sefa zvakanaka.
