AMAFUTHA, IGASI, KANYE NEKHEMIkhali

Ezimbonini zikawoyela, igesi, namakhemikhali, ikakhulukazi phakathi nezinqubo zokumba, izikrini zocingo eziwuhlaka zivikela esihlabathini nakwezinye izinto eziyizinhlayiya. Lezi zikrini zakhiwe ngokunemba ukuze zihlunge ngokuphumelelayo izinto ezilimazayo ezingase zilimaze izinto zokusebenza futhi zithiye ukusebenza. Ezimweni ezinzima nezifunayo zokumba uwoyela negesi, ubuqotho besistimu yokuhlunga bubalulekile.

Enye yezinhlelo zokusebenza eziyinhloko zezikrini ze-wedge wire emkhakheni kawoyela negesi njengamadivaysi okulawula isihlabathi. Ngesikhathi sokumba, ukwakheka okuqukethe izinhlayiya zesihlabathi ezixegayo kungawela emgodini womthombo, kubangele ukuguguleka kanye nokungasebenzi kahle kwemishini. Izikrini zocingo lwe-Wedge zisetshenziselwa ukusebenza njengesithiyo, ukuvimbela lezi zinhlayiya zesihlabathi ukuthi zingangeni ku-tubing yokukhiqiza kanye nokuqinisekisa indlela ecacile yokuthi ama-hydrocarbon ageleze phezulu. Lokhu akugcini nje ukwandisa isikhathi sokuphila kwemishini yokukhipha amanzi kodwa futhi kuthuthukisa ukusebenza kahle okuphelele kwenqubo yokukhipha.

Izikrini zocingo lwe-Wedge zisebenza eminye imisebenzi eminingi ebalulekile ekusebenzeni komthombo kawoyela negesi. Zibalulekile ekulawulweni kwemvula, zisiza ekulawuleni nasekunciphiseni ukunqwabelana kwezinsalela ezingase zivale amanzi omthombo noma zidale izinkinga zokukala. Ngesikhathi sokusebenza kukasimende, okubandakanya ukuvala isikhala se-annular phakathi kwepayipi lokubhoboza kanye nodonga lomthombo, lezi zikrini zisiza ekugcineni izici zokugeleza ezifiselekayo ze-slurry kasimende, ukuqinisekisa ukubekwa kahle nokusetha. Ekuhlanzweni kwamanzi embonini kawoyela negesi, izikrini zezintambo ze-wedge zisusa kahle ukungcola emanzini akhiqiziwe ngaphambi kokuthi aphinde akhishwe noma alahlwe, ngaleyo ndlela kube nomthelela ekuvikelweni kwemvelo kanye nokuhambisana nomthetho.

Ukumelana nokugqwala okukhethekile namandla aphezulu ezikrini zentambo ye-wedge kusuka ekusetshenzisweni kwezinto eziphambili njengensimbi engagqwali, ezizivumela ukuthi zikwazi ukumelana nemiphumela eyonakalisayo yamakhemikhali, izingcindezi eziphezulu, namazinga okushisa adlulele atholwa kulezi zimboni. Lokhu kuzenza zilungele ukufakwa kwesikhathi eside lapho ukuzinza nokuqina kubaluleke kakhulu. Ikhono labo lokulondoloza ukusebenza kokuhlunga okungaguquki phakathi nezikhathi ezinwetshiwe lihumusha izindleko ezincishisiwe zokulungisa kanye nokuphepha okuthuthukisiwe kwabaqhubi.
