Sezvo zvinodiwa nevanhu zvekuchengetedza nharaunda zviri kuramba zvichiwedzera kuomarara, zvinodiwa zvemavharuvhu zviri kuwedzerawo, uye zvinodiwa zvehuwandu hwemvura inoputika, inobvira uye inoputika mumiti yepetrochemical zviri kuramba zvichiwedzera kuomarara. Mavharuvhu midziyo inokosha mumiti yepetrochemical. , Mhando dzayo nehuwandu hwayo hwakakura, uye ndeimwe yenzvimbo huru dzinoburitsa mvura mumudziyo. Kune michina ine chepfu, inobvira uye inoputika, mhedzisiro yekubuda kwekunze kwevharuvhu yakakomba kupfuura kubuda kwemukati, saka zvinodiwa zvekunze kwevharuvhu zvakakosha zvikuru. Kubuda kwemvura kushoma kwevharuvhu zvinoreva kuti kubuda kwemvura chaiko kudiki kwazvo, izvo zvisingagone kutsanangurwa nemiedzo yemazuva ese yekumanikidzwa kwemvura uye kuvharwa kwemhepo. Zvinoda nzira dzakawanda dzesainzi uye zvishandiso zvehunyanzvi kuti zvione kubuda kwemvura kudiki kwekunze.

Maitiro anowanzo shandiswa pakuona kudonha kwemvura kwakaderera ndeekuti ISO 15848, API624, EPA method 21, TA luft uye Shell Oil Company SHELL MESC SPE 77/312.

Kuti zvizadzise zvinodiwa zvekudonha kwemvura kushoma, mavharuvhu anofanirwa kusangana nezvinodiwa zvekuyedzwa kwegesi yehelium. Nekuti huremu hwemamorekuru ehelium hudiki uye huri nyore kupinda, mhando yekudonha ndiyo kiyi. Chechipiri, chisimbiso chiri pakati pemuviri wevharuvhu nechivharo chekupedzisira chinowanzova chisimbiso chegasket, chinova chisimbiso chisingachinji, chiri nyore kusangana nezvinodiwa zvekudonha kwemvura. Uyezve, chisimbiso chiri pamudzi wevharuvhu chisimbiso chinoshanduka. Zvidimbu zvegrafiti zvinobviswa nyore nyore mupakeji panguva yekufamba kwemudzi wevharuvhu. Naizvozvo, kurongedza kwakasarudzika kwekudonha kwemvura kunofanirwa kusarudzwa uye kupatsanurwa pakati pekurongedza nemudzi wevharuvhu kunofanirwa kudzorwa. Kupatsanurwa pakati pesleeve yekumanikidza nemudzi wevharuvhu nebhokisi rekuisa zvinhu, uye kudzora kushata kwemudzi wevharuvhu nebhokisi rekuisa zvinhu.
