Ama-valve epulasitikizisetshenziswa emikhakheni eminingi ekuthuthukisweni kwezimboni zezwe lami, futhi imikhiqizo yepulasitiki embonini yamakhemikhali neyokuvikela imvelo ibaluleke kakhulu. Kucaciswe ngokusobala ukuthi ijubane lentuthuko lidinga ukusheshiswa, futhi selidonse ukunaka okukhulu eminyangweni kazwelonke, okudinga amapulasitiki onjiniyela bezwe lami ukuze kusheshiswe intuthuko. Ngakho-ke, ochwepheshe bezimboni babikezela ukuthi imboni yepulasitiki yezwe lami izobhekana nentuthuko kuzo zonke izici, ikakhulukazi ekuthuthukisweni kwemikhiqizo yepulasitiki yobunjiniyela. Ukuthuthukisa ikhono lokusungula elizimele lemboni yokucubungula amapulasitiki, ukuthandwa kwezinto ezintsha, ubuchwepheshe obusha, imishini emisha kanye nemikhiqizo emisha sekuyinto ehamba phambili.

Ama-valve ebhola epulasitiki,izivalo uvemvanefuthihlola ama-valveziyimikhiqizo ebalulekile emndenini we-valve, ikakhulukazi ngoba lawa ma-valve enziwe ngamapulasitiki wobunjiniyela, ngakho-ke kokubili ngokusebenza nokusebenza, anezinzuzo ezithile. Izinga lamanje lokusebenzisa amavalvu epulasitiki ezweni lami Ekukhuleni konyaka nonyaka, izinkampani eziningi seziqalile ukuthenga amavalvu epulasitiki, futhi ezinye izinkampani zamavalvu zakwamanye amazwe zihlasela imakethe enkulu yezwe lami, zikhombisa umkhuba wokuqhakaza yonke indawo ezweni.

Amavalvu ebhola epulasitiki, amavalvu ovemvane namavalvu okuhlola kubaluleke kakhulu kwamanye amaphrojekthi okuvikela amakhemikhali nemvelo. Ngenxa yokusebenza okuphezulu kwama-valve epulasitiki, angakwazi ukuhlangabezana nezidingo zephrojekthi kangcono kunamanye ama-valve ensimbi engagqwali, ngoba ama-valve epulasitiki anesisindo esincane, kulula ukuyifaka, futhi abiza ngempumelelo. Ithengeka kakhulu futhi ingagwema ngokuphumelelayo inkinga yokudonsa, futhi umthamo we-valve yepulasitiki incane kakhulu, indawo yaphansi nayo incane, ilula kakhulu ekuthuthweni nasekufakeni, futhi ukuhlakazeka nokugcinwa kulula. Ngakho-ke, amathuba okusebenzisa ama-valve epulasitiki kubunjiniyela Amathemba aya ngokuya eba makhulu futhi aba nethemba elikhulu.

Namuhla, izwe lami selingumkhiqizi omkhulu, umthengi kanye nomthengisi wemikhiqizo yepulasitiki emhlabeni jikelele. Abanye abahlaziyi bathi njengoba ubuchwepheshe be-coal-to-olefin buvuthwa futhi busetshenziswa kabanzi, imikhiqizo yepulasitiki kancane kancane ithatha indawo yensimbi, ingilazi, amapayipi amakhemikhali, ama-valve nezinye izimboni ziyamukelwa, amapulasitiki asekelwe ku-bio kanye namanye amapulasitiki awonakele futhi ezinye izinto ezintsha seziqala ukuvela. malitshalwe. isicelo.

Esikhathini esizayo, ukuthuthukiswa kwemboni yepulasitiki kuzoxhomeka emandleni ebhizinisi ngokwalo ngakolunye uhlangothi, futhi ngakolunye uhlangothi lizothembela emandleni amabhizinisi aqoqwe ndawonye. Yonke imboni yamakhemikhali okuvikela imvelo izoba amandla okuthuthukisa imboni yepulasitiki. Abakhiqizi badinga ukuthuthukisa amandla abo obuchwepheshe futhi ngokuqhubekayo bathuthukise ikhwalithi yemikhiqizo yabo ngenkathi benciphisa izindleko, ukuze uphawu lwabo lwe-valve yepulasitiki lukwazi ukuhola indlela endaweni yamagagasi amakhulu nesihlabathi.
