This invention relates to processes for producing acetic acid and, in particular, to improved processes for recovering permanganate reducing compounds formed during the carbonylation of methanol in the presence of a carbonylation catalyst to produce acetic acid. Alkyl halides are removed or reduced from the recovered permanganate reducing compounds.

FIELD: chemistry.SUBSTANCE: method of drying and purifying hydrocarbon propellants involves combined deep drying and purification of hydrocarbon material, which is carried out by passing a liquid-phase mixture through sorbents in three series-arranged adsorbers. The first adsorber on the process path is filled with aluminium oxide, the second adsorber is filled with aluminium oxide or zeolite NaA and the third adsorber is filled with zeolite NaX or zeolite CaA or zeolite CaX.EFFECT: obtaining a ...

FIELD: chemistry.SUBSTANCE: method of producing hydrocarbon propellants involves combined drying and cleaning of hydrocarbon material and separating the hydrocarbon propellant composition. The hydrocarbon material used is propane, a butane fraction or isobutane or n-butane or propane or a mixture of propane and n-butane. Drying and cleaning is carried out by passing the material in liquid-phase through sorbents in three series-arranged adsorbers. The first adsorber on the process path is filled ...

A method of cleaning a waste water vessel 100 for the waste water industry comprises adding a first quantity of a first reagent to the waste water vessel, adding a second quantity of a second reagent to the waste water vessel, the first and second reagents being reagents that react together in an exothermic reaction whose products comprise sodium chloride and nitrogen. Heat generated from the exothermic reaction causes solidified fat, oil and/or grease (FOG) deposits 105 in the waste water vesse...
