Ngaphezu kwe-hydrogen sulfide, igesi yokuqhekeka kwe-petroleum ivame ukuqukethe inani elithile le-sulfur ephilayo. Isihluthulelo sokunciphisa okuqukethwe kwe-sulfur ukususwa ngempumelelo kwe-sulfur alcohol kanye ne-hydrogen sulfide kugesi eluhlaza. Isihlungi sama-molecular singasetshenziswa ukumunca amanye amakhemikhali aqukethe i-sulfur. Isimiso sokumunca sihlanganisa ikakhulukazi izici ezimbili:
Ukukhetha ukuma kanye nokumuncwa. Kuneziteshi eziningi zokuvula ezifanayo esakhiweni sesihluzo sama-molecule, ezingagcini nje ngokuhlinzeka ngendawo enkulu yangaphakathi, kodwa futhi zikhawulela isilinganiso sama-molecule anokungena okukhulu kokuvula.
2- ukumuncwa kwe-polar, ngenxa yezici ze-ion lattice, ubuso besihluzo se-molecular bune-polarity ephezulu, ngakho-ke bunamandla aphezulu okumuncwa kwama-molecule angagcwele, ama-molecule e-polar kanye nama-molecule ahlukaniswe kalula. Isihluzo se-molecular sisetshenziswa kakhulu ukususa i-thiol kugesi yemvelo. Ngenxa ye-polarity ebuthakathaka ye-COS, efana nesakhiwo se-molecular se-CO2.2, kukhona umncintiswano phakathi kokumuncwa kwesihlungo sama-molecule lapho kukhona i-CO22Ukuze kube lula inqubo futhi kuncishiswe ukutshalwa kwezimali kwemishini, i-molecular sieve adsorption sulfate ivame ukusetshenziswa kanye nokuphelelwa amanzi emzimbeni ngesisefo sama-molecule.
Ukuvulwa kwesihlungi sama-molecule se-JZ-ZMS3, JZ-ZMS4, JZ-ZMS5 kanye ne-JZ-ZMS9 kungama-0.3nm, 0.4nm, 0.5nm kanye no-0.9nm. Kutholakale ukuthi isihlungi sama-molecule se-JZ-ZMS3 asimunyi i-thiol, isihlungi sama-molecule se-JZ-ZMS4 simunca umthamo omncane kanti isihlungi sama-molecule se-JZ-ZMS9 simunca i-thiol ngamandla. Imiphumela ikhombisa ukuthi umthamo wokumunca kanye nezakhiwo zokumunca ziyanda njengoba i-aperture ikhula.
