3 Ukhetho
3.1 Uhlobo
Ivalvu yebhabhathane inezakhiwo ezahlukeneyo ezifana nohlobo lwepleyiti enye engaqhelekanga, etyebileyo, uhlobo lomgca ophakathi, engaqhelekanga kabini kunye ne-engaqhelekanga kathathu. Uxinzelelo oluphakathi lusebenza kwi-shaft yevalvu kunye nebheyari edlula kwipleyiti yebhabhathane. Ke ngoko, xa ukumelana nokuhamba koxinzelelo oluphezulu kunye nobubanzi obuncinci kukhulu, ububanzi be-shaft kunye nobukhulu bepleyiti yebhabhathane buya kwanda ngokufanelekileyo. Ukuba kusetyenziswa iivalvu zesango, iivalvu zebhola okanye iivalvu zeglobe, ukusuka kwimiba yokutywina kunye nokumelana nokuhamba. Uhlalutyo lufanelekile ngakumbi kunevalvu yebhabhathane.

Ukuba kusetyenziswa iivalvu zesango, iivalvu zebhola okanye iivalvu zeglobe, ukusuka kwimiba yokutywina kunye nokumelana nokuhamba. Uhlalutyo lufanelekile ngakumbi kunevalvu yebhabhathane.
Kwiminyaka yakutshanje, ukuvela kweevalvu zesango ezitywiniweyo ezithambileyo kwiinkqubo zamanzi kuye kwaphucula ukusilela kweevalvu zesango ezilula ukutyibilika. Ukumelana kwayo nokuhamba kwamanzi kuncinci, kwaye ingalungiswa kwi-intanethi. Ifanelekile kakhulu kwiidayamitha ezincinci neziphakathi, ngoko ke iye yasetyenziswa kancinci kancinci.
3.2 Isibini sokutywina
Iingenelo eziphambili zevalvu yebhabhathane yokutywina ngentsimbi kukuvalwa okuthembekileyo, ukuhlala ixesha elide, ukumelana nobushushu obuphezulu, akukho lula ukuyonakalisa nokukrazula, kunye nomthamo wokuthwala uxinzelelo oluphezulu. Ke ngoko, isetyenzisiwe kakhulu kwiminyaka yakutshanje, ngakumbi kwiindawo eziphambili zeenkqubo zobunjineli. Ukuba ivalvu yebhabhathane yokutywina ngerabha ethambileyo iyilwe kwaye yenziwe kakuhle, inokuvalwa kakuhle, kwaye ububanzi obukhulu bunokutshintshwa ngokulula kwi-intanethi. Nangona kunjalo, irabha ineengxaki zokuguga kwaye ingasetyenziswa kuphela kwiimeko zokusebenza apho ubushushu bungekho phezulu, ngoko ke isetyenziswa kakhulu kumanzi empompini nakwiinkqubo zokubonelela ngamanzi.

Iivalvu zebhabhathane zokutywina isinyithi sangaphandle zikwasetyenziswa kwizikhululo zokumpompa, ii-condenser, iinkqubo zokukhupha umphunga kunye neenkqubo zokutshintshiselana kobushushu kwizikhululo zamandla obushushu. Izikhululo zamandla enyukliya zikwasetyenziswa kwizikhululo zoxinzelelo, iinkqubo zokutshiza kunye netyuwa, njl.njl., ukwahlukanisa ioyile kunye nomphunga kwiinkqubo zokucoca ipetroli. Ivalvu yokubonelela, inkqubo yokususa isulfurization kunye nonyango lwegesi yomsila, ukuqhekeka kobushushu kunye neyunithi yokulungisa. Kukwakho nezityalo zepetrochemical, iinkqubo ze-cryogenic, ze-slurry kunye nezephepha.
Kwiimeko zobushushu obuphakathi kunye noxinzelelo oluphakathi, kungcono ukusebenzisa iivalvu zebhabhathane ezitywiniweyo ngentsimbi. Kwiindawo ezifuna ukuthembeka okuphezulu, ubomi obude, kunye nokutshintshwa ixesha elide, kufuneka kusetyenziswe neevalvu zebhabhathane ezitywiniweyo ngentsimbi.
Kwivalvu esetyenziselwa amanzi obushushu obuqhelekileyo, ukuba ayifuni kakhulu, ayizukutshintshwa ixesha elide okanye apho kunzima ukuyitshintsha, kuyacetyiswa ukuba usebenzise ivalvu yebhabhathane enesakhiwo esithambileyo sokutywina. Ukuba umgangatho werabha unokuqinisekiswa, iivalvu zebhabhathane ezinkulu zamanzi kufuneka zibe ziivalvu zebhabhathane ezihlala kwirabha.
4 Isiphelo
Ukuvela okuqhubekayo kwetekhnoloji entsha kunye nezixhobo ezintsha kuya kuphucula ukusebenza kwesakhiwo sevalvu yebhabhathane, kwandise uluhlu lokusetyenziswa kwevalvu yebhabhathane, kwaye kubeke phambili iimfuno ezihlaziyiweyo zoyilo kunye nokukhetha ivalvu yebhabhathane.
