UMongameli Biden usanda kumemezela ukuthi enye indlela kaphethiloli ye-E-15 izotholakala ukuze ithengiswe ezinyangeni zasehlobo. Lokhu kwanda kokuthengiswa kuzokwandisa nokukhiqizwa kwe-ethanol kanye nemikhiqizo ehambisana nayo. Enye yemikhiqizo ehlanganisiwe—i-DDGS—iyisithako sokuphakelayo esicebile esinamaphrotheni esikhethwa yizilwane ezelusayo, izingulube nezinkukhu embonini yezolimo. Ukuze uthole okuningi kumkhiqizo ohlangene we-DDGS, abakhiqizi be-ethanol kufanele babheke kubuchwepheshe bokuhlukanisa. ST Izinsiza kusebenza & Ubuchwepheshe busetshenziswa ngokwahlukana electrostatic ukwandisa okuqukethwe kwamaprotheni ku-DDGS futhi unikeze abakhiqizi be-ethanol indlela entsha yemali engenayo.
I-E-15 ingenye indlela kaphethiloli evuselelekayo esebenzisa i-ethanol ukunciphisa ukukhishwa kwekhabhoni. I-Ethanol ine-carbon intensity ephansi nge 40-50% uma kuqhathaniswa nophethiloli ovela ku-petroleum. I-E-15 ihambisana kakhulu nemvelo ngoba idala inhlanganisela ye 15% ethanol kuye 85% gasoline with a lower carbon footprint and burns cleaner than other gasoline options.
Ngokuhambisana ne-Clean Air Act, I-E-15 ivinjelwe ukuthi ithengiswe ehlobo ngenxa yokukhathazeka ngokungcoliswa komoya. Nokho, ngenxa yenhlekelele yaseRussia/Ukraine kanye nomthelela ekuthengisweni kukaphethiloli, UMongameli Biden ukhiphe incwadi Uhlelo lwe-Emergency Fuel Waiver lokho kuvumela ukuthi i-E-15 ithengiswe kuleli hlobo. Lesi sinqumo senziwe ngomzamo wokunciphisa izindleko zikaphethiloli kanye nokunikeza abashayeli ezinye izindlela zokuthutha uphethiloli.
Ngoba i-E-15 idinga i-ethanol eningi ukuze ixutshwe, ukukhiqizwa kwe-ethanol kulindeleke ukuthi kukhuphuke. Ngesikhathi sokukhiqizwa kwe-ethanol, i-co-products nayo iyadalwa. Enye yale mikhiqizo edidiyelwe—i-DDGS—naleyo kulindeleke ukuthi ikhule nasekuthengisweni. DDGS (ama-distillers owomile okusanhlamvu ane-solubles) iwumkhiqizo ohlangene wokukhiqiza i-ethanol esetshenziswa njengokudla kwezilwane zezolimo.
okungaba nzima ukuhlangabezana I-USDA, “Ukulingisa ukwandisa ukukhiqizwa kwe-ethanol, Ukukhiqizwa kwe-DDG kwenyukele phezulu kusukela ekuqaleni kwawo-2000, […] Nakuba ukunikezwa kukhule kakhulu, izitayela zentengo ezikhuphukayo ziphakamisa ukuthi isidingo sihambisana nokuhlinzekwa […] Njengoba i-DDGS iyi-coproduct yokukhiqizwa kwe-ethanol, ekugcineni ukukhiqizwa kwe-DDGS kuncike ekudingweni kukaphethiloli.” Lokhu kusho ukuthi njengoba isidingo se-ethanol sikhula, so too does the production of DDGS.
Njengoba i-DDGS ingumkhiqizo ohlangene ocebile ngamaprotheni wokukhiqiza i-ethanol, abalimi abaningi kanye namabhizinisi emkhakheni wezolimo bazowusebenzisa njengokuphakela imfuyo. Nokho, the immediate co-product available from ethanol production does not contain enough protein to be used in higher-value feed applications such as aquaculture and pet food in large quantities.
Ukuze ukhiqize izithako ze-DDGS ezifaneleka kakhulu kokubili ama-ruminants kanye ne-monogastrics, abakhiqizi abaningi be-ethanol babheka izindlela zokuhlukanisa i-DDGS ibe yimikhiqizo enamaprotheni anothe kanye ne-protein engenamafutha. STET offers a water-free fractionation process that can generate a high-value protein ingredient that meets the needs and demands of monogastric feeds.
ST Izinsiza kusebenza & Ubuchwepheshe buhlinzeka ngenqubo yokuhlukaniswa kwe-DDGS ezimele ngokuphelele esitshalweni se-ethanol. Inqubo yokuhlukanisa i-STET ingatholakala eduze kwesitshalo se-ethanol, noma yikuphi kuchungechunge lwenani lesithako le-DDGS (ngaphandle kwendawo yokugaya ukudla, Ngokwesibonelo). Inqubo STET iphumelela kakhulu ekukhiqizeni a 48% I-protein DDGS ingxenyenamba elungele ukusetshenziswa ku-aqua yenani eliphezulu nezabelo zezilwane ezifuywayo. The fiber-rich material remains a highly desirable ingredient in cattle and dairy rations.
Ingabe isitshalo sakho se-ethanol noma isigayo sokuphakelayo sikulungele ukwandisa imali engenayo ngokwakhiwa kwe-DDGS yamaprotheni amaningi? ST Izinsiza kusebenza & Ubuchwepheshe kungasiza. Ngobuchwepheshe bethu besimanje kanye nezindlela zokuhlukanisa, I-STET isize amakhasimende emhlabeni wonke ukuthuthukisa inzuzo ngokuqhubekayo. Ufuna ukufunda okwengeziwe? Xhumana nathi namuhla!
