REX-SO2
REX-SO2 is also marketed under the brand names 'CutClean', 'Tarclean' and 'OrangeWorks' depending on locale. It is a powerful solvent all of whose active ingredients derive from Oranges. This is classified as a non-hazardous solvent (except for the normal issue of not allowing inhalation into the lungs). It is immiscible in water so cannot cause emulsions. It will dissolve all petroleum hydrocarbons, whatever their condition. It is widely used for all engineering related degreasing work, clearing up legacy waste problems, oil spill, heavy contamination in tanks, pipelines and any structure where immediate results are required.
It is used by ADCO for clearing wax plugged wells, Saudi Aramco for tank cleaning, Banoco for tank cleaning and wellbores among many others. It is used for foreshore cleaning in the event of marine oil spill.
