Paraffin inhibitors, and paraffin suppressant compositions and methods

Disclosed are paraffin inhibitors, paraffin suppressant compositions, and methods of making and using them. The paraffin inhibitors comprise polymers of a maleic moiety polymerized with at least two olefins having hydrocarbon chains of a different length from each other. When added to hydrocarbon me...

Zusammenfassung:	Disclosed are paraffin inhibitors, paraffin suppressant compositions, and methods of making and using them. The paraffin inhibitors comprise polymers of a maleic moiety polymerized with at least two olefins having hydrocarbon chains of a different length from each other. When added to hydrocarbon media such as crude oils to form crude oil compositions, the paraffin inhibitors inhibit the precipitation of paraffin waxes in the crude oil compositions and exhibit reduced precipitation, gelling, and/or crystallization from the hydrocarbon media when the media are subjected to sustained low temperatures.
