Lanzhou petrochemical titanium nanopolymer coating immersion anti-corrosion test was successful.

November 17 proved that Lanzhou Petrochemical in the oil separation device maintenance for the first time using a new titanium nanopolymer
coating
immersion anti-corrosion technology, 4 heat exchangers for new material anti-corrosion treatment, after nearly a month of monitoring, all internal anti-corrosion heat exchangers are running well.
March, Lanzhou petrochemical and material manufacturers and construction parties on-site repeated research and demonstration, decided to use a new titanium nanopolymer coating oil separation device 1 heat exchanger (E-5) tube bundle for corrosion testing. After 6 months of testing, the new titanium nanopolymer material solves the problem of tube bundle scale, avoids the blockage caused by the attachment of catalytic crystals after heating, solves the corrosion problem caused by chlorine, sulfur and other elements to the equipment, and the corrosion phenomenon of the original tube bundle outer wall epoxy amino coating is not resistant to oil corrosion.
the application of this technology has achieved three results: First, the heat exchanger heat exchange efficiency is 15.3% higher than the original, improve the temperature of raw materials into the furnace, effectively reduce the operating load of the furnace, can save a lot of energy costs. Second, extended the life of the tube bundle and maintenance cycle, from the original 2 cleaning times a year to a maximum of 1 time, the tube bundle renewal cycle further extended. Only heat exchanger maintenance and heat exchanger tube bundle update, is expected to save nearly 20 million yuan per year. The third is to reduce the operational risk brought about by maintenance, to ensure the safe and sound operation of each refining device.
