PROCESS FOR REDUCING THE VISCOSITY OF HEAVY RESIDUAL CRUDE OIL DURING REFINING

摘要

Additives may be used to decrease the viscosity of heavy residual hydrocarbons. The additives are prepared using a formulation comprising: a first component selected from the group consisting of (alkoxylated)-(di or tri)- alkyl phenol - aldehyde (amine) resins; a-Olefin - maleic anhydride co¬ polymers and grafted polymers including half ester/amide and full ester/amide derivatives; and combinations thereof; and a second component which is a synergist and selected from the group consisting of polyamines, amidoamines, imidazolines, and combinations thereof.
