Application of Titanium Petroleum Parts
Under the condition of petroleum mechanical processing, the following titanium equipment can be manufactured with titanium alloy: titanium heat exchanger, filter (precipitator), storage tank, locking device, sewage pipeline and rough oil pipeline for storing petroleum and petroleum products. Some petrochemical enterprises and petroleum processing industries have experience in manufacturing and using titanium alloy equipment. For example, Moscow Petroleum Processing Plant manufactures the following equipment from BT1-0 titanium alloy: propylene polymerization reactor, decomposer decomposer pulsator, condenser, scrubbing tower. Titanium-lined containers can be used for evaporation (concentration) or distillation, or for reactions in weak acids or other chloride-containing solutions. Titanium-lined containers can also be used for nitriding organic materials with nitric acid and chemical reactions with other oxidizing media. Solution containing chromic acid and chromic acid solution vulcanizing can be selected according to the reaction temperature needs of this container with titanium lining. It has been proved that copper and other solutions containing gases can be used as catalysts for the catalytic oxidation of carbon chloride compounds when the pH value is determined. Then, when catalysis is carried out at about 150-200 t: temperature, the corresponding equipment must be set up, and acetaldehyde production equipment made of titanium is widely used. Towers, pipes, valves lined with titanium and acid pumps composed of rotors and stators are all made of Engineering pure titanium. Distillation column is often used for acetic acid purification, and most of the components included in the fractionation stage are made of titanium. For example, the middle layer and connecting parts of tower for distillation unit. Serpentine tube heater, which can prevent the formation of metal sulfate, after testing, compared with copper serpentine tube heater plated with aluminum, heat conduction increased by 30%. For urea reactor, in order to obtain (recover) carbon black and eliminate stress, a reactor with a diameter of 43M and a length of 8.2m withstanding 120T: temperature and 130kPa pressure is used. The reactor is designed to reduce the pressure of gas and other gases. This equipment is made of titanium. The application of titanium is further extended to crude oil and petroleum processing industry. The desalination equipment for producing fresh water or drinking water from seawater or organic acid are all made of titanium. At the same time, pumps, tubes and heat exchangers made of welded titanium tubes are reliable and durable through practice. Titanium seed plate for cathode is made of titanium plate in copper electrolysis.
