I-Shell kunye ne-tube yokutshintshiselana kobushushu zisetyenziswa ngokubanzi kumashishini amaninzi ngenxa yokusebenza kwawo okuphezulu kunye nokusebenza okuthembekileyo:
Ishishini lemichiza: isetyenziselwa ukufudumeza okanye ukupholisa izinto kwiinkqubo ezahlukeneyo zokusabela, ezifana ne-synthetic ammonia, ukucocwa kwe-oyile, njl.
Ishishini le-petroleum: isetyenziselwa ukufudumeza kwangaphambili kunye nokuchithwa kwe-oyile ekrwada kwinkqubo yokwenziwa kwe-oyile ekrwada.
Umzi-mveliso wokutya: usetyenziselwa ukufudumeza okanye ukupholisa ekusetyenzweni kokutya, njengokuvala ubisi, ukuxinana kwejusi, njl.
Umzi-mveliso wamandla: usetyenziswa kwizixhobo zombane ukupholisa umbhobho weinjini yomoya okanye enye inkqubo yemidiya.
