Beschreibung
Zusammenfassung:	Disclosed herein are paraffin suppressant compositions, and methods of making and using them. The compositions comprise a paraffin inhibitor, a hydrocarbon-soluble hydrotrope equivalent, and optionally one or more additional paraffin dispersants. When added to hydrocarbon media such as crude oils to form crude oil compositions, the suppressant compositions inhibit the precipitation of paraffin waxes in the crude oil compositions. The suppressant compositions, added to hydrocarbon media such as hydrocarbon solvents or crude oils, exhibit reduced precipitation, gelling, and/or crystallization of paraffin inhibitor from the hydrocarbon media, when the media are subjected to sustained temperatures between 4° C. and −60° C.
