The role of the temperature control unit in the distillation system
The temperature control of the distillation system is mainly composed of four parts: heating device, distillation device, circulating cooling water device and receiving device. The heating device is equipped with a heating rate intelligent control function, which can realize precise control of heating temperature and heating efficiency, high distillation efficiency and good condensation effect; the circulating cooling device is equipped with a cooling temperature display and control function to ensure the cooling effect. The receiving device is equipped with distillation end point detection and automatic heating stop function, which realizes intelligent heating control. The heating rate intelligent control function is set for the heating device of the sub-assembly, which can realize the precise control of heating temperature and heating efficiency; the distillation device is a patented design, with high distillation efficiency and good condensation effect. The circulating cooling device is equipped with a cooling temperature display and control function. To ensure the cooling effect, the receiving device is equipped with distillation end point detection and automatic heating stop function, which realizes intelligent heating control.
The distillation system is a special liquid-liquid separation technology. Under high vacuum, the mean free path of vapor molecules is greater than the distance between the evaporation surface and the condensation surface, so that the evaporation rate of each component in the liquid can be used. Difference, separation of liquid mixtures. The pressure difference between the boiling film and the condensing surface is the driving force for the flow of steam, and a slight pressure drop will cause the flow of steam.
The refrigeration and heating distillation intelligent control system is suitable for supporting the use of the distillation system for natural gasoline, automotive gasoline, aviation gasoline, spray fuel, solvents with special boiling points, naphtha, diesel, distillate fuel and similar petroleum products. The intelligent control system for refrigeration, heating and distillation is an important quality index for evaluating the vapority of liquid fuels. It can not only indicate the boiling point range of liquid fuels, but also judge the general content of the light and heavy components in the oil composition, which is of great significance to production, use, storage and other aspects.
When the intelligent control system of refrigeration heating distillation decides the processing plan of a crude oil, it must first know the quantity of light and heavy fractions contained in it. By measuring the distillation range, the crude oil contains gasoline, kerosene, light diesel and other fractions. How much. The refrigeration heating distillation intelligent control system controls the operating conditions of the oil refining unit during the distillation process, such as temperature, pressure, liquid level in the tower, steam consumption, etc., based on the results of the distillation range of the distillate. The refrigeration heating distillation intelligent control system is matched with the measurement of the fuel distillation range, which can preliminarily determine the type of fuel according to different boiling point ranges, determine the fuel distillation range of the engine, and identify its evaporability, thereby judging the applicability of the oil in use.
The cold and heat source control system of LNEYA distillation system is mainly used in the fields of chemical pharmacy. The temperature range is -120℃~350℃. It can be directly cooled at high temperature, fast and save heat transfer medium.
