<p>A method for the controlled introduction of a reagent into a liquid, preferably a reagent permeable substantially hydrocarbon liquid, which method comprises the steps of: (a) placing as in a geological crude oil reservoir solid polymeric bodies, each body comprising a reagent permeable polymeric matrix containing a substantially water insoluble reagent such as at least one of a wax crystal modifier, demulsifier, scale inhibitor, corrosion inhibitor, biocide, ashless dispersant, antioxidant and mixtures thereof in said liquid (includes both crude and refined hydrocarbon liquids); and, (b) leaching out said reagent from said bodies at a controlled and predetermined rate into said liquid.</p> |
