Mathematical Study of Temperature Measurement by Thermocouple in Chemical Processes

Abstract

Processing of oil, gas and gas condensate is one of the most widespread areas of modern chemical-technological processes. Due to the safety of chemical and technological process management, strict requirements have been set for the quality of processes in the oil and gas refining and petrochemical industries. During chemical-technological processes in the oil and gas industry, the fractional composition of the product, the typical boiling point, the octane number of gasoline, the cetane number of diesel fuel, the evaporation temperature, the ignition temperature and other parameters must be determined with special accuracy. This set of characteristics is used in the laboratory assessment of the quality of oil, oil products and gas condensate. Temperature measurements performed during such processes must have maximum accuracy. For this reason, the determination of temperature by thermocouples in the above-mentioned chemical processes has been mathematically studied and evaluated during the research.
