Musoro: Mhedzisiro yeKupisa kweHydrocarbon
Kupiswa kwemahydrocarbon inzira yemakemikari yakajairika muhupenyu hwemazuva ano. Mahydrocarbon, makemikari anoumbwa nehydrogen nekabhoni, anogona kuwanikwa mumafuta efossil akadai sepetroleum, gasi rechisikigo, uye marasha. Kana mahydrocarbon apiswa, simba rinochengetwa mumakemikari aro rinoburitswa muchimiro chekupisa nechiedza. Kunyange zvazvo maitiro aya akakosha kuzvikamu zvakasiyana-siyana zvakaita sekufambisa, maindasitiri, uye mhuri, kukanganisa kwaanoita nharaunda nehutano hwevanhu kwakakosha uye kunofanirwa kutariswa.
1. Kuburitswa kweGasi Rinodziya Mudenga
Imwe yemigumisiro yakakosha yekupiswa kwemahydrocarbon imhepo inoburitsa magasi egreenhouse. Carbon dioxide (CO2) ndiyo inonyanya kugadzirwa nekupiswa kwemahydrocarbon, uye kuwedzera kwehuwandu hweCO2 mumhepo kwakabatsira zvikuru pakuchinja kwemamiriro ekunze pasi rose. CO2 imhepo inoburitsa magreenhouse, zvichireva kuti ine simba rekupinza nekuburitsa mwaranzi ye infrared, ichideredza kupisa kunoburitswa nePasi muchadenga, uye ichibatsirawo pakupisa magreenhouse. Mugumisiro wekupedzisira kuwedzera kweavhareji yekupisa pasi rose, iyo inobatanidzwa nekuchinja kwakasiyana-siyana kwemamiriro ekunze, kusanganisira kukwira kwemvura yegungwa, kuchinja kwemamiriro ekunze, uye kuwedzera kwehuwandu nekusimba kwenjodzi dzechisikigo dzakadai semadutu nekusanaya kwemvura.
2. Kusvibiswa kweMhepo
Kusvibiswa kwemhepo ndeimwewo mhedzisiro huru yekupiswa kwehydrocarbon. Kupisa mafuta efossil kunoburitsa mhando dzakasiyana dzezvinosvibisa mumhepo, zvinosanganisira carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), uye fine particulate matter (PM). CO2 igesi rine chepfu yakawanda rinogona kukanganisa kufamba kweokisijeni mumuviri wemunhu kana rikafemerwa nehuwandu hwakawanda. SO2 neNOx ndidzo dzinotungamira kunaya kweasidhi, izvo zvinogona kukuvadza masango, kusvibisa mvura, uye kuwedzera ngura yezvivakwa zvakagadzirwa nevanhu. NOx uye volatile organic compounds (VOCs) zvinoitawo basa mukuumbwa kwesmog ne tropospheric ozone, izvo zvine mhedzisiro yakaipa pahutano hwevanhu nemagariro ezvisikwa.
3. Mhedzisiro Yehutano
Kusvibiswa kwemhepo kunokonzerwa nekupiswa kwehydrocarbon kwakakomba pahutano. Kusangana nezvinhu zvidiki uye zvinosvibisa mweya zvinogona kukonzera kana kuwedzera zvirwere zvakasiyana-siyana, kusanganisira zvirwere zvekufema zvakaita seasthma nebronchitis, chirwere chemwoyo, uye kenza yemapapu. Zvinosvibisa mhepo zvakabatanidzwawo nenjodzi yakakura yekurohwa nesitiroko nezvirwere zvekufema, pamwe nekuwedzera kwekufa nekurwara muvanhu vasina dziviriro, vakaita sevana, vakwegura, uye vanhu vane zvirwere zvekare.
4. Kukuvadzwa kwezvakatipoteredza
Kupiswa kwemahydrocarbon kunewo migumisiro yakasiyana-siyana inokuvadza pamamiriro ekunze. Kuwedzerwa kweasidhi muvhu nemvura kunokonzerwa nemvura ine acid kunogona kukonzera kukuvara kwakananga kumiti nemhuka. Uyezve, kuwedzera kwehuwandu hweCO2 mumhepo kunogona kukonzera shanduko mumakemikari emvura yegungwa, inozivikanwa se ocean acidification. Kuwedzerwa kweasidhi mugungwa kunogona kukanganisa zvipenyu zvemugungwa zvinovimba necalcium carbonate kuti zvigadzire ganda nemapfupa, zvakaita se mollusks nemakorari, zvichizopedzisira zvakanganisa cheni yechikafu chemugungwa.
5. Kuwedzera Kushandiswa Kwesimba Rinodzokororwa
Kuziva kuri kuwedzera nezvemigumisiro yakaipa yekupiswa kwemahydrocarbon kwakaita kuti nyika dzakawanda nemakambani vatsvage dzimwe nzira dzesimba dzakachena uye dzinogara kwenguva refu. Simba rinogona kudzokororwa sezuva, mhepo, magetsi emvura, uye biomass rave kutariswa zvakanyanya senzira yekuderedza kuvimba nemafuta epasi uye kuderedza kuburitswa kwemagasi anodziya pasi. Matekinoroji esimba rinogona kudzokororwa haangope mhinduro dzinochengetedza nharaunda chete asiwo ane mukana wekugadzira mikana mitsva yehupfumi kuburikidza nekugadzira mabasa muchikamu chezvekurima.
6. Matambudziko Nezvipingamupinyi
Kunyange zvazvo paine mabhenefiti akajeka kubva mukuderedza kushandiswa kwemahydrocarbon uye kuchinjira kumagetsi anodzokororwa, matambudziko akawanda nezvipingamupinyi zvichiri kufanira kukundwa. Zvinhu zvehupfumi, zvakaita semitengo yepamusoro yekutanga yekugadzira nekuisa matekinoroji esimba rinodzokororwa, zvinogona kuva chipingamupinyi chikuru. Uyezve, nyaya dzehunyanzvi dzakadai sekuwedzera kwegrid uye matekinoroji ekuchengetedza simba akavimbika, pamwe nenyaya dzemitemo nedzemitemo, dzinofanira kugadziriswa kuti shanduko yesimba ibudirire.
7. Matanho Ekuderedza Dambudziko
Kuti kuderedze migumisiro yakaipa yekupiswa kwemahydrocarbon, matanho akasiyana-siyana ekuderedza kusvibiswa anogona kutorwa. Izvi zvinosanganisira kushandiswa kwetekinoroji yekudzora kusvibiswa, senge mafirita ezvimedu uye masisitimu ekutora nekuchengetera kabhoni (CCS), pamwe nekuwedzera kushanda zvakanaka kwesimba mumaindasitiri nekufambisa. Mitemo yehurumende inotsigira kuvandudzwa nekushandiswa kwesimba rinogona kuvandudzwa, senge zvinokurudzira mitero, rubatsiro, uye mitemo yakasimba yekuburitsa utsi, inoitawo basa rakakosha mukusimudzira shanduko.
Pamusoro pezvo, kuedza kwemunhu mumwe nemumwe, kwakadai sekuderedza kushandiswa kwemotokari dzemunhu, kuwedzera kushandiswa kwesimba remagetsi kumba, uye kutsigira zvigadzirwa nemakambani asingakuvadzi nharaunda, zvakakoshawo mukuderedza migumisiro yekupisa mahydrocarbon panharaunda uye pahutano.
Mhedziso
Kupiswa kwemahydrocarbon kunobatsira zvikuru mumatambudziko akasiyana-siyana ezvakatipoteredza nehutano pasi rose, kusanganisira shanduko yemamiriro ekunze, kusvibiswa kwemhepo, uye kuparadzwa kwezvakatipoteredza. Kunyange hazvo matambudziko achiripo mukuderedza kuvimba nemahydrocarbon uye kuchinja kune simba rakachena, matanho anoenderera mberi anotorwa nehurumende, makambani, nevanhu vanogona kubatsira kuderedza kukanganisa. Kuedza uku kwakakosha pakuchengetedza pasi rose nehutano hwevanhu, ukuwo kuchikurudzira kukura kwehupfumi hunogara kwenguva refu uye hune hushamwari nezvakatipoteredza.
