Imishini ye-PCC

Ukukhiqizwa kwenqubo ye-PCC kuvela endaweni yamakhemikhali yokubuka, ngokusobala kulula kakhulu.

Amandla: 30,000-300,000tta

Inqubo yokukhiqiza iqala nge-limestone deCarbonation (Caco3) ku-kiln, lapho itholakale khona i-lime (CAO) namagesi (CO2).

I-Lime igcotshwe ngenqubo ephakeme, esihlahleni esitholwa se-slurry ye-lime hydroxide emanzini ngokweqile (CA (oh)} NH2O) ohlanjululwe ekungcoleni okunzima.

I-slurry ekhiqizwe ngale ndlela ifakwa ngokusondelene namagesi acebile we-CO2 aqhamuka eKiln, ngokwesibonelo edonsayo ye-CACO3 ezokwenza lokho, noma enomile futhi omiswe ukuze athole i-powder ehlakazekile kahle.

Esebenza ngokuhlanganiswa kokuhlukahluka kwenqubo njengoba:

Ukukhishwa komugqa / ubisi lweLime

ukuphendula kwe-lime

Ukushisa okushayayo

Ukugxila Okuqinile

I-CO2 kugxile

Ukucubungula isengezo samanzi

ukungaculiko

Kungenzeka ukunquma ukwakheka kwesikhathi esizayo kwamakristalu e-carbonate (i-calcite - ukuthola ukulawulwa kwamapharamitha amathathu okuqala ahlukanisa indawo ethile ye-PCC, i-granulometry nebanga elimhlophe.

Mer ngemuva kweminyaka eminingi yokuthuthukiswa kwezobuchwepheshe kanye nemikhiqizo yayo, usebenzisa ukusekelwa okuthile kwezobuchwepheshe kochwepheshe ababili be-PCC ezingeni lomhlaba wonke, sekuqalile ukubhekana nobunjiniyela nokwakhiwa kwezitshalo zokukhiqizwa kwe-PCC.

Imishini ye-PCC yamukela izingxenye ezithuthukile zokuhlanzeka kanye nokucindezela izingxenye ezithambile zesayensi, nezinto ezikhethekile zokuzenzakalelayo ukuqinisekisa ukusebenza kahle okuphezulu, ukonga amandla nokukhiqizwa kwezinzile, ikhwalithi yemikhiqizo yamukelwa ngumhlaba.

Imishini ye-PCC yimishini yokukhiqiza ebalulekile ye-calcium hydroxide kusuka ku-Quicklime. Isakhiwo siqukethe igobolondo, i-Shell Shembe, uhlelo lokuhambisa, uhlelo lokufafaza kanye nohlelo lokulawula.

I-Merxh - I-C Diget iwumshini omusha wokukhiqiza owenzelwe isisekelo sokuthola ubuchwepheshe obuthuthuke kwabezizwe, futhi ukusebenza kwawo kwezobuchwepheshe kuvumelaniswa nezinga eliphakeme lomhlaba. Lolu hlobo lokugaya luqukethe i- -} kanye nomqoqi wothuli. Iyunithi, umgadli wangempela we-Middle Priep Priep uwuhlobo lwe-Shaft Double, ijubane le-shaft liyashintshwa, umgadli wesibili u-shaft eyodwa, umgadli we-Tertiary agaya shaft. Iyunithi iqinisa ingxube yezinto ezibonakalayo namanzi, ithuthukisa amandla okuguga kwe-digermer, ukuze i-carboniferous ingagaywe ngezinga elikhulu, futhi ikhwalithi yomkhiqizo ingathuthukiswa ngezinga eliphakeme.
