Application of titanium tube heat exchanger in the field of petroleum fittings

Under the conditions of petroleum machining, titanium alloy can be used to manufacture the following titanium equipment: titanium heat exchangers, filters (precipitators), storage tanks for petroleum and petroleum products, locking devices, sewage pipes and crude oil pipelines.

Some petrochemical enterprises and petroleum processing industries have manufacturing experience and use experience of titanium alloy equipment.

Vessels with a titanium lining may be used for evaporation (concentration) or distillation or for reactions in weak acids or other chloride-containing solutions, and subsequently for the nitriding of organic materials with nitric acid and for chemical reactions with other oxidizing media. The container with a titanium lining can be used for both the solution containing chromic acid and the chromic acid solution for vulcanization according to the reaction temperature.

A range of applications in the field of chemical raw material industry has confirmed that the use of copper and other gasification containing solutions for the catalytic oxidation of carbon chlorine compounds can be used as a catalyst when the pH value is determined. Then, when the catalytic temperature is about 150~200t:, the corresponding equipment must be set up, and the acetaldehyde production equipment made of titanium is widely used. Titanium lined towers, pipes, valves, and acid pumps with rotors and stators are all made of engineered pure titanium. Distillation columns are often used for acetic acid purification, and most of the assemblies included in the fractionation stage are made of titanium. For example, the middle layer and connecting parts of the tower used in the distillation unit.

Serpentine tube heaters, which prevent the formation of metal sulfates, have been tested to increase heat transfer by 30% compared to aluminized copper serpentine tube heaters. For the urea reactor, in order to obtain (recover) carbon black and for stress relief, a 43m diameter and 8.2m long reactor is used to withstand 120T: temperature and 130kPa pressure, which is to reduce the pressure of gas and various other gases. This equipment is made of titanium.

The application field of titanium has been further extended to the crude oil and petroleum processing industry, and the desalination equipment for making fresh water or drinking water from seawater or the equipment for making organic acids are all using titanium. At the same time, the pumps and conduits and heat exchangers made of welded titanium tubes have been tested by practice and are reliable and durable. Titanium plates are used to make titanium seed plates for cathodes when copper is electrolyzed.
