Protecting equipment from mechanical impurities during liquid hydrocarbon transport and production is a critical task. Various types of strainer filters are used for this purpose. However, filter operation involves an increase in pressure drop and contamination of the filter element, which in turn leads to higher operational costs for liquid pumping and filter maintenance. The study objective is to investigate the design of vertical strainers utilized in the oil industry. To unify the results, all parameters of the studied filter are presented without units of measurement, enabling the results to be scaled to other filter sizes. This article describes ways to improve the performance of strainer filters used in oil transportation. Using numerical modeling and a software package for automated batch calculations, the dependence of the pressure drop on the filter design parameters was determined. The presented design optimization options are selected based on the minimum capital costs for reconstructing the filter connection assembly. The methods for solving this problem, the software packages used, and additional design tools are described. The results obtained are analyzed, and the feasibility of their application is presented. Specific recommendations are given on the optimal position and angle of the inlet and outlet nozzles, the optimal radius of the filter element, and the optimal wave parameters in the case of a corrugated filter element.
