Ukuguqula ukukhutshwa kweCarbon: Indima ye-CCUS kuZinzo lwezoShishino

Ukutyhalwa kwehlabathi ngokuzinza kuye kwakhokelela ekuveleni kweCarbon Capture, Utilization, and Storage (CCUS) njengeteknoloji ebalulekileyo ekulweni nokutshintsha kwemozulu. I-CCUS iquka indlela ebanzi yokulawula ukukhutshwa kwekhabhoni ngokubamba i-carbon dioxide (CO2) kwiinkqubo zoshishino, ukuyiguqula ibe yimithombo ebalulekileyo, kwaye igcinwe ukukhusela ukukhutshwa kwe-atmospheric. Le nkqubo intsha ayiphuculi nje kuphela ukusebenza kakuhle kokusetyenziswa kweCO2 kodwa ikwavula iindlela ezintsha zokusetyenziswa kwayo, iguqula into ebikade ithathwa njengenkunkuma ibe yimveliso yexabiso.
Embindini we-CCUS kukubanjwa kwe-CO2, inkqubo eye yatshintshwa ziinkampani ezifana ne-TCWY kunye nezisombululo zabo eziphambili zokubamba ikhabhoni. Irhasi yeflue ephantsi yoxinzelelo lwe-TCWYukubamba i-CO2iteknoloji ngumzekelo ophambili, okwaziyo ukukhupha i-CO2 ngococeko ukusuka kwi-95% ukuya kwi-99%. Le teknoloji iyaguquguquka, ifumana izicelo kwiindawo ezahlukeneyo zemizi-mveliso ezifana negesi yebhoyila, ukukhutshwa kweplanti yamandla, igesi ye-kiln, kunye negesi ye-coke oven flue.
Ukuphuculwa kweteknoloji ye-MDEA ye-decarbonization yi-TCWY ithatha inkqubo inyathelo eliya phambili, inciphisa umxholo we-CO2 kwi-≤50ppm emangalisayo. Esi sisombululo silungele ukucocwa kwe-LNG, igesi eyomileyo yokucoca, i-syngas, kunye negesi ye-oveni ye-coke, ebonisa ukuzibophelela kwenkampani ekuboneleleni ngezisombululo ezilungiselelwe iimfuno ezahlukeneyo zamashishini.
Ngeemfuno ezingqongqo zokunciphisa i-CO2, i-TCWY ibonelela ngetekhnoloji ye-decarbonization yoxinzelelo (VPSA). Le ndlela ehamba phambili inokunciphisa umxholo we-CO2 ukuya ngaphantsi njenge-≤0.2%, iyenze ilungele ukusetyenziswa kwimveliso ye-ammonia yokwenziwa, i-methanol synthesis, ukuhlanjululwa kwe-biogas, kunye nokulungiswa kwegesi yokulahla.
Impembelelo ye-CCUS idlulela ngaphaya kokubanjwa kwekhabhoni. Ngokusebenzisa i-CO2 ebanjiweyo njenge-feedstock yeeplastiki ezinokubola, izichumisi zebhayoloji, kunye nokuphucula ukufunyanwa kwegesi yendalo, ubugcisa be-CCUS obufana nobo buphuhliswe yi-TCWY buqhuba uqoqosho olujikelezayo. Ngaphaya koko, ugcino lwejoloji ye-CO2 luyaphuculwa ukuze kuphuculwe ukubuyiswa kwe-oyile, kubonisa iingenelo ezininzi ze-CCUS.
Njengoko i-scope yenkonzo ye-CCUS iqhubeka nokukhula ukusuka kumandla ukuya kwikhemikhali, amandla ombane, i-samente, insimbi, ezolimo, kunye namanye amacandelo abalulekileyo akhupha i-carbon-emitting, indima yeenkampani ezifana ne-TCWY iya ibaluleke kakhulu. Izisombululo zabo ezintsha azikho nje ubungqina obunokuthi bubekho kwi-CCUS kodwa kunye nokukhanya kwethemba kwikamva elizinzileyo apho ukukhutshwa kwekhabhoni kungeyiyo imfanelo kodwa isibonelelo.
Ukuqukumbela, ukudityaniswa kobuchwephesha be-CCUS kwiinkqubo zoshishino kubonisa inyathelo elibalulekileyo ekulweni nokutshintsha kwemozulu. Ngeenkampani ezifana ne-TCWY ekhokela intlawulo, umbono wekamva le-carbon-neutral uya ufikeleleka ngakumbi, ubonisa ukuba ngeteknoloji efanelekileyo kunye nezinto ezintsha, ukuzinza kunye nokukhula kwamashishini kunokuhamba kunye.
