Industrylọ ọrụ ngwa ụlọ wepụrụ friji R22 kpamkpam n'ime ngụkọ
Dị ka Montreal Protocol si kwuo, akwụsịla refrigerant R22 na mba ndị mepere emepe ma ka nwere ike ịmepụta ya na mba ndị ka na-emepe emepe, mana mmepụta ya na ojiji ya bụ 2030.
Na Jenụwarị 26, 2021, Ministry of Ecology and Environment nyere ọkwa na ntinye nke mmepụta, ojiji na mbubata 2021 maka ihe na-emebi ozone (nke a na-akpọ ya dị ka ọkwa). Dị ka iwu nke ndị mmadụ Republic of China maka mgbochi na njikwa nke mmetọ ikuku, iwu maka njikwa ihe ndị na-eme ka ihe ndị na-eme ka ikuku ozone na ihe ndị ọzọ dị mkpa, a ga-enye ụlọ ọrụ 20 na oke mmepụta nke 292,795 tọn hydrochlorofluorocarbons ( HCFC) na 2021, yana nkeji iri anọ na isii ka a ga-eji oke ojiji nke 31,726 tọn hydrochlorofluorocarbons na 2021.
Tụnyere 2020, oke mmepụta nke hydrochlorofluorocarbons (HCFCS) gụnyere HCFC-22 agaghị agbanwe agbanwe na 2021, ebe oke ojiji a ga-ebelata nke ukwuu, na-ewepụ HCFCS na ụlọ ọrụ ngwa ụlọ nke China.
A ga-enye oke mmepụta nke hCFC nwere (HCFC) maka hCFC-141B, HCFC-142B, HCFC-22, HCFC-123, HCFC-124 na HCFC-133A. N'ime ha, HCFC-141B bụ onye na-emepụta ụfụfụ nke a na-eji na friji na ụlọ ọrụ ọkụ mmiri. Dị ka usoro ịfụfụ na ụlọ ọrụ refrjiraeto ka emelitere gaa na HFC-245FA + cyclopentane foaming system, na Jenụwarị 1, 2019, ụlọ ọrụ na-ekpo ọkụ mmiri amachibidoro iji HCFC-141B kpamkpam. A na-eji Hcfc-141b mee ihe dị obere na ụlọ ọrụ ngwa ụlọ. Ngụkọta oke mmepụta maka hCFC-141B na 2021 bụ tọn 50,878, agbanwebeghị site na 2020.
E jiri ya tụnyere mmepụta oke maka HCFC-22, ngụkọta ojiji maka hCFC-22 na ụlọ ọrụ ikuku oyi na 2021 bụ tọn 31,726, mbelata nke 3,489 tọn site na 35,215 tọn na 2020. Nke a nwere njikọ chiri anya na mgba ọkụ refrigerant. ụlọ ọrụ ntụ oyi ụlọ. Oke ahịa nke ikuku ikuku HCFC-22 na ụlọ ọrụ ntụ oyi nke ụlọ bụ ihe dịka 20% na 2019, na nke a ga-aga n'ihu na-agbada na 2020. Ụlọ ọrụ mkpuchi ikuku nke China emeela ọmarịcha ihe ịga nke ọma n'ịkwụsị HCFC-22.
Usoro nchịkwa nke HCFC-22 maka ụlọ ọrụ ntụ oyi ụlọ na China site na 2021 ruo 2026 bụ ndị Kọmitii Executive nke Multilateral Fund kwadoro, ma gbaa mbọ iwepụ 70% nke hCFC-22 oriri site na 2026, nke karịrị nke usoro Montreal Protocol chọrọ iji nweta mbelata hCFC-22. Anyị ga-enyekwu onyinye na mmejuputa iwu nke Montreal Protocol nke China.
