The corrosion products in the oil and part of the reaction materials and equipment are deposited on the wall of the heating pipe, and the single side is heated, and finally a solid scale layer is formed, which seriously affects the heat transfer coefficient. If the shell side uses saturated steam, the amount of fouling is very small, only the superheated steam or steam is of poor quality, and the shell side will slowly scale. It can be seen that the main cause of scaling of the heater tube is the oil, and the shell side is the grade of steam. The two seals are closed to prevent scaling. The oil removal problem of compressors and anti-corrosion air compressors is mostly oil-lubricated in the 14th section of the compressor, while the five-stage piston ring is operated by oil-free lubrication of PTFE. Therefore, ultrafiltration technology can be applied to the four sections of the compressor. To make the CO into the tower without oil, and to install the ultra-filter element on the anti-corrosion air compressor, the satisfactory effect can be achieved, and the problem of scaling of the heater can be avoided. Application of ultrafiltration technology in methanol process (1) Methanol oil The main function of methanol oil is to separate the oil supplied to the methanol synthesis tower and the recycle gas for the purpose of protecting the methanol catalyst. Since the loading amount of the methanol catalyst is generally small, the life of the copper-based catalyst is shorter than that of the iron-based catalyst, and the ultrafiltration technology is used to greatly improve the purification degree of the raw material gas of the methanol, and the life of the catalyst can be greatly prolonged. After applying the ultrafiltration technology, the oil and water content in the gas can be 0.05-6. The specific method is similar to that of the ammonia synthesis oil, but the configuration of the ultrafiltration element can be higher, and the purification degree is 5 times higher than that of the ammonia synthesis oil. (2) The main function of the alcohol washing tower alcohol washing tower is to reduce the methanol content in the raw material gas, to avoid the production of alcohol wax and affect the refining operation, so the washing and separation of the alcohol washing tower is particularly important.
