Isistimu yokuhlola eqhubekayo ye-PX
Incazelo Yomkhiqizo
Uhlelo lwamukela umqondo wokuklama we-modular, futhi zonke izinto zokusebenza namapayipi ahlanganiswe ohlakeni.Ihlanganisa izingxenye ezintathu: iyunithi yokudla, iyunithi yokusabela kwe-oxidation, kanye neyunithi yokuhlukanisa.
Isebenzisa ubuchwepheshe bokulawula obuthuthukisiwe, ingahlangabezana nezidingo ezikhethekile zesistimu yokusabela eyinkimbinkimbi, izinga lokushisa eliphezulu nokucindezela okuphezulu, ukuqhuma, ukugqwala okuqinile, izimo ezivimbelayo eziningi, nokulawula okunzima nokusebenza kahle okuhlukile ekukhiqizeni kwe-PTA.Amathuluzi ahlukahlukene kanye namathuluzi okuhlaziya aku-inthanethi anokunemba okuphezulu nokuzwela, futhi ahlangabezana nezidingo zamaphutha amancane esivivinyweni.Ukuhlelwa kwamapayipi ezinqubo ezihlukahlukene ohlelweni kunengqondo futhi kulula ukusebenza.
Imishini namapayipi, ama-valve, izinzwa namaphampu ohlelweni zenziwe ngezinto ezikhethekile ezifana ne-titanium TA2, Hc276, PTFE, njll., exazulula inkinga yokugqwala okuqinile kwe-acetic acid.
Isilawuli se-PLC, ikhompyutha yezimboni kanye nesofthiwe yokulawula isetshenziselwa ukulawula okuzenzakalelayo kwesistimu, okuyindawo yokuhlola ephephile nephumelelayo.
Inqubo eyisisekelo
Shisisa kuqala isistimu, futhi uyihlanze nge-nitrogen kuze kube yilapho okuqukethwe komoyampilo kwegesi yomsila we-outlet kunguziro.
Engeza okuphakelayo okuwuketshezi (i-acetic acid kanye ne-catalyst) ohlelweni futhi uqhubeke ushisisa isistimu kumazinga okushisa okusabela.
Engeza umoya ohlanzekile, qhubeka ushisisa kuze kube yilapho kuqalwa ukusabela, bese uqala ukuhlanganisa.
Uma izinga le-liquid lama-reactants lifinyelela ubude obudingekayo, qala ukulawula ukuphuma, futhi ulawule isivinini sokukhipha ukuze ugcine izinga loketshezi lizinzile.
Kuyo yonke inqubo yokusabela, ukucindezela ohlelweni ngokuyisisekelo kuzinzile ngenxa yengcindezi yangaphambili ne-back-up.
Ngokuqhubeka kwenqubo yokusabela, yokusabela kombhoshongo, igesi esuka phezulu kombhoshongo ingena kusihlukanisi segesi-uketshezi nge-condenser futhi ingena ethangini lokugcina impahla.Ingabuyiselwa embhoshongweni noma ikhishwe ebhodleleni lokugcina impahla ngokwezidingo zokuhlola.
Ngokusabela kweketela, igesi evela kukhava yeketela ingangeniswa ku-condenser endaweni yokukhipha umbhoshongo.Uketshezi olujiyile luphindiselwa emuva ku-reactor ngepompo egelezayo engashintshi, bese igesi ingena ohlelweni lokwelapha igesi yomsila.

I-Polymer polyols (POP) uhlelo lokusabela
Incazelo Yomkhiqizo Lolu hlelo lufanele ukusabela okuqhubekayo kwezinto zesigaba segesi-uketshezi ngaphansi kokushisa okuphezulu nokucindezela okukhulu.Isetshenziswa kakhulu ekuhlolweni kokuhlola izimo zenqubo ye-POP.Inqubo eyisisekelo: amachweba amabili anikezwa amagesi.Ichweba elilodwa yi-nitrogen yokuhlanza ukuphepha;omunye umoya njengomthombo wamandla wevalvu yomoya.Izinto eziwuketshezi zibalwa ngokunembile nge-electron...

Isistimu yokusabela ye-polyether yokuhlola
Incazelo Yomkhiqizo Lonke isethi yesistimu yokusabela ihlanganiswe kuhlaka lwensimbi engagqwali.I-valve yokudla ye-PO/EO igxilile ohlakeni ukuze kuvinjelwe ukulinganisa isikali sika-elekthronikhi ukuthi singathinteki phakathi nokusebenza.Isistimu yokusabela ixhunywe nepayipi lensimbi engagqwali namavalvu enaliti, okulula ukunqanyulwa nokuxhunywa kabusha.Izinga lokushisa lokusebenza, izinga lokugeleza kokuphakelayo, kanye ne-P...

Isistimu yokulungisa yokuhlola
Ukusebenza komkhiqizo nezici zesakhiwo Iyunithi yokuphakela izinto ezibonakalayo yenziwe ithangi lokugcina impahla eluhlaza elinyakazayo futhi lishisisa nokulawula izinga lokushisa, kanye nemojula yesisindo ye-Mettler kanye nesilinganiso esinembile sephampu ye-advection ye-micro-metering ukuze kuzuzwe ukulawulwa kokuphakelayo okuncane nokuzinzile.Izinga lokushisa leyunithi yokulungisa lifinyelelwa ngokubambisana okuphelele kwe-prehe...
