The role of the correct choice of measuring instruments in the process of delayed coking

This work is devoted to assessing the impact of the correct choice of temperature and pressure measuring instruments in the process of delayed coking on its effectiveness for one of the domestic enterprises of the petrochemical industry. The importance of constant monitoring of the surface temperature of the furnace coil pipes, as well as the pressure in the raw material flows to prevent the process of coking equipment and the need to use measuring instruments for these parameters with the metrological characteristics required to obtain reliable results is shown. The analysis of the operation of temperature and pressure measuring instruments used at the enterprise is carried out, the need for their replacement is justified. The selection of samples of temperature and pressure measuring instruments of domestic production was carried out, a comparative analysis of their metrological characteristics and experimental studies were carried out to verify that the measurement results correspond to real values. Based on the results of the study, recommendations are made.
