| Abstract: |
| The interaction between acrylic ester polymer pour point depressant and crude oil wax hydrocarbon component was studied by Monte Carlo simulation. The molecular structure of pour point depressant was also designed and optimized. According to the results of simulation, the copolymer pour point depressant was synthesized with octadecyl acrylate, polar monomer maleic anhydride and styrene. The results show that pour point depressant is most sensitive to crude oil when the optimal ratio of these three copolymer monomer is 8∶1∶1. The experimental results are consistent with simulation results, which confirms the reliability of this simulation method. |
