Kusar organiki na sa'adon (VOCs) suna ne kusar organiki dai dai wanda suka zoce lokacin gas 133.32 Pa a cikin hanyar wata da lokacin sani da kwayoyin su ne baya 50–260°C a cikin lokacin hanyar atmosfiri, kuma wanda suka zoce kusar organiki dai dai mataki ko maye a cikin lokacin hanyar waɗansu da atmosfiri.

1. Takardun Kusar Organiki Na Sa'adon (VOC) Gas
Kusar organiki na sa'adon (VOCs) suna ne kusar organiki dai dai wanda suka zoce lokacin gas 133.32 Pa a cikin hanyar wata da lokacin sani da kwayoyin su ne baya 50–260°C a cikin lokacin hanyar atmosfiri normali, kuma wanda suka zoce kusar organiki dai dai mataki ko maye a cikin lokacin waɗansu da atmosfiri.
Babban shi a cikin tabbatar kima, VOCs yana gudanar daidai wajen alkanes, aromatic hydrocarbons, alkenes, halogenated hydrocarbons, esters, aldehydes, ketones, da makon kawai. Kullum mai tsawo yana daidai wajen hydrocarbons, halogenated hydrocarbons, oxygenated hydrocarbons, da nitrogen-containing hydrocarbons, misali cewa aromatic series compounds, organic chlorides, freons, organic ketones, amines, alcohols, simple and complex esters, acids, da petroleum hydrocarbon compounds.

Kadannan, haka ya gabatar:
• Aromatic hydrocarbons (benzene, toluene, xylene, styrene, da makon kawai)
• Aliphatic hydrocarbons (butane, n-butane, gasoline, da makon kawai)
• Halogenated hydrocarbons (carbon tetrachloride, chloroform, vinyl chloride, da makon kawai)
• Freons
• Alcohols, aldehydes, ketones, polyols (methanol, propanol, isobutanol, formaldehyde, acetaldehyde, acetone, cyclohexanone, da makon kawai)
• Simple ethers, phenols, epoxides (ether, methylphenol, phenol, ethylene oxide, propylene oxide, da makon kawai)
• Esters da addin gida (ethyl acetate, butyl acetate, daga cikakken)
• Amines, kwallon nitrile (dimethylformamide, acrylonitrile, daga cikakken)
• Bakwai (methyl bromide, chlorofluorocarbons, daga cikakken)
Yayi na ita sunaƙwar shirin VOCs ake samun binciken ayyukan masu aiki.

2.Matakin Volatile Organic Compound (VOC) Gas

1. Matakin Gas VOC a Cikin Shekara Koalin
Gas mataki a cikin shekarar koalin ya fi maras bakwai: tsarin koalin zuwa coke da tsarin koalin zuwa gas.

1.1 Gas matako a cikin Koalin da Coke

Yan duniya na kuma shawar daidai ne a cikin wannan suna da ke ciki da idonin, coking, mai tsarin kimiya downstream. A cikin idonin coal, raw coal ya zage jama'a dai dai da hanyar air kawai, yayi kara masu smoke, dust, mai wani gaba polycyclic aromatic hydrocarbons. VOCs a cikin coking stage ya fiye mai waniwa kimiya da wastewater treatment areas. Waniwa kimiya ya gabatar da cold drainage section, desulfurization section, ammonium sulfate section, da crude benzene section, mai ake bayan pollutants da characteristics of emissions.
1. Cold Drainage Section:
Kimiya gas Volatile gareshen gareshen ne ammonia, hydrogen sulfide, naphthalene, da kwayoyin amounts of VOCs. Emissions ya fiye a tar tanks, ammonia water tanks, intermediate tar tanks, tar pipelines, da underground seal tanks, yayi characterized by continuous emission, high concentration, da both low and high temperature conditions.
2. Kasaƙen Desulfurization / Ammonium Sulfate:
Kasance gaskuwa mai tsawo aikin amoniya da hidrojin sufayidi, kuma yadda VOCs biyu. Ayyukan ne tankan marasabin masaka, tankan bayyana, da tankan kasarci na waniya. Kasance ne continuous da amoniya gabata.
3. Kasaƙen Benzene Raw:
Kasance unorganized gabata benzene series compounds, ya zo tankan benzene raw, tankan oil de-benzolized, tankan washing oil, tankan underground, da tankan dosing. Kasance ne kawai mutane, kamar gabata, amma dai dai cikin gabatar.
4. Wastewater Treatment Area:
Kasance shugaban gas da hanyoyin ƙasa. Pollutants major benzene series compounds, hidrojin sufayidi, da nitrogen. Ayyuka ne emergency combustion tanks, regulating tanks, anaerobic tanks, filter press areas, etc., characterized by large volume, low concentration, and high moisture content.

3.Ayyuka na VOC Emissions a Cikin Enterprises Printantun da Packaging
Packaging da printantun zai iya shigar da sabon raba:
1. Daga fajin rubutun: tsarin suna a cikin waniyar kaya, kaya jirgin maiwurin, kaya jirgin sanyan, da kaya jirgin wani matakan.
2. Daga fajin tsarin suna: lithography (tsarin offset), gravure printing, flexographic printing, embossing, screen printing, da wani.

Bayan rubutun shugaban, goma na VOC a cikin hikar kaya da tsarin suna yana bache 2 million tons. Wannan bachi ne ya kasance domin a matsayin tsarin suna, dry, laminating (compounding), da cleaning processes. Matakan na farko yana domin inks, adhesives, coating solutions, dampening fluids, cleaning agents, da wani organic solvents, ke yi release VOCs daga natural evaporation da drying-related volatilization.

Sekitorin rubutu a cikin sayarwa na sani da sayarwa na alamunna yana iya soya mai tsarin VOC a cikin yadda. Don take da hanyar marketin da tsarin fadi, rubutarsa ke yi amfani da sabon labari kuma mai shugata a kan ethyl acetate, toluene, butanone (MEK), da isopropanol.
Babu wane, alamar da aka yi amfani da daga systemin tsarin gasin sanarwa ke ne ya kamata da ya amfani da su a cikin sayarwa na alamunna da aka rubuta a cikin material na sani.

4. Tsawo mai tsarin VOC a cikin Enterprise da aka yi Rubutu da Application

Rubutu da application ke yi amfani da processin sanarwa kama na paint mixing, rubutu (don includes primer, intermediate, top coats, da varnish), leveling layers, drying, da steps da aka gabatar da su.

Don take da National Economic Industry Classification Standard (GB/T 4754-2017), industries dai aka rubuta da associated VOC emissions typically include:
• Furniture manufacturing (C21)
• Karkashin metallurgy (C33)
• Suna mai amfani a cikin karkashin alambari (C34)
• Alambari karkashen kusalli na cikin wata labari (C35)
• Karkashin mota (C36)
• Alambari karkashen railway, sabon kwaya, aerospace, da wata labarai ne (C37)
• Samun gida, suna mai amfani da fiter da amfani a cikin alambari (C43)

A cewa sunan labarai, bayarar VOC yana domin ga daga wannan suna suka yi shi a cikin rubutuwa, kasance, gabatar da sauka. Bayarar su yana domin ga daga solvents, thinners, da additives don rubutuwa da coatings. Wannan yadda, polisi na hankaliyyar hadarawa, strategiya mai tsallace da management na VOC yana kawai kula don suna mai amfani a cikin rubutu.
