ABSTRACT:
This invention relates to particulate compositions containing chemical additives for petroleum systems. The particulate compositions when added to petroleum systems gradually dissolve over a period of time, releasing the chemical additive, so as to improve the petroleum system. The use of such particulate compositions has an advantage over the use of the chemical additive itself since the pellets give longer residence time and sustained treatment over a longer period.
