I-Pilot Reactor yokuhlolwa okuqhubekayo kwe-PX Oxidation

I-Pilot Reactor yesilingo esiqhubekayo se-PX Oxidation Isithombe Esifakiwe
  • I-Pilot Reactor yokuhlolwa okuqhubekayo kwe-PX Oxidation

Incazelo emfushane:

Lolu hlelo lusetshenziselwa ukusabela kwe-PX oxidation okuqhubekayo, futhi lungasetshenziselwa ukulingisa uhlobo lombhoshongo kanye nohlobo lweketela ekukhiqizweni kwezimboni.Uhlelo lungaqinisekisa ukuphakelwa okuqhubekayo kwezinto zokusetshenziswa kanye nokudedelwa okuqhubekayo komkhiqizo, futhi luhlangabezane nezidingo zokuqhubeka zokuhlolwa.

Uhlelo lwamukela umqondo womklamo 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 nokwenza okuhlukile ekukhiqizeni kwe-PTA.Amathuluzi ahlukahlukene kanye namathuluzi okuhlaziya aku-inthanethi anokunemba okuphezulu nokuzwela, futhi ahlangabezana nezidingo zephutha elincane ekuhlolweni.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, ikhompuyutha yezimboni kanye nesofthiwe yokulawula isetshenziselwa ukulawula okuzenzakalelayo kwesistimu, okuyindawo yokuhlola ephephile nephumelelayo.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

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 bese ushisa ngokuqhubekayo 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, futhi igesi ingena ohlelweni lokwelapha igesi yomsila.
