In order to achieve production targets for fuel and petrochemical products to support national energy security, reliable equipment is needed to support the operation of petroleum processing refineries. Main equipment such as injection pumps must be able to adapt to the expected operational conditions. Check valve is one of the supporting components of injection pump reliability. Research was conducted to determine the velocity characteristics of two ball type check valve designs using Computational Fluid Dynamics (CFD) numerical simulations. In this research, three variations of pump stroke length were simulated, namely 25%, 50% and 100% with three variations of solid particle size, namely 200, 250 and 300 microns. The fluid that passes through the check valve is a solid-liquid mixture of catalyst and particles. The analysis carried out is by comparing the velocity values as well as the flow patterns produced for each variations used. The simulation results show that of all the variations tested, the model with a stroke length of 100% produces the maximum velocity. In addition, the size of solid particles is inversely proportional to fluid velocity and flow. From the results of this research, it was also found that model 2 has more potential for backflow towards suction, and also model 2 has more potential for clogging because particles that should flow stop inside the check valve.

Currently, oil and natural gas are still the main energy needed by society. To maintain energy security, it is necessary to carry out studies on the characterization of oil and gas field reservoirs.
