Problems encountered when exploiting and transporting crude oil containing solid paraffins is that it easily crystallizes under normal temperature, causing many challenges such as paraffin wax deposition, reduced flow rate, gel formation, loss of pipe pressure... When the crude oil temperature is below the wax appearance temperature (WAT), paraffin will precipitate and separate from the oil. Many solutions that have been and are being used such as insulation, mechanical, thermal, chemical methods, using wax inhibitors - pour point depressants (PPD) and dispersants... The method of using additives to increase solidification temperature or inhibit wax, improve the rheology of crude oil and reduce paraffin deposition is considered one of the most effective method.
In this study, polymers made from a combination of three monomers, behenyl acrylate, stearyl methacrylate and vinyl acetate, were studied to find the most optimal combination for the purpose of manufacturing pour point lowering additives for oils.
