Identification of the Equipment Failure Fundamental Causes by the Condition Monitoring Using Twin Digital Models

Abstract

The work is devoted to the problems of identifying the fundamental reasons that led to an increase in energy consumption for heating raw materials and cooling reaction products to the required temperatures, as well as to a decrease in the productivity of a diesel hydrotreating unit when the limiting parameters of the technological regime are reached. The purpose of the work is to determine the parameters of heat exchangers, in particular, pollution factors, and parameters of the technological process, in particular, the consumption of raw materials, the consumption of fuel gas. Monitoring was carried out during the introduction of reagents in order to solve the problems associated with the formation of resinous deposits. It was revealed that the reagents have an insignificant effect both on improving the heat transfer coefficient and on reducing the specific consumption of fuel gas. It is proposed to clarify the dosage of reagents and to develop a project on the use of reagents to maintain the cleanliness of the heat exchange surface of the raw material heat exchangers of the diesel fuel hydrotreating unit.
