Titanium equipment used in the chemical industry and petrochemical industry

Titanium exhibits excellent corrosion resistance towards oxidizing and gaseous media containing corrosive agents, can inhibit the presence of reducing acids in compounds, and is highly insensitive to point corrosion, preventing intergranular corrosion and preventing the occurrence of corrosion stress. Therefore, it has been widely applied in the manufacturing of chemical equipment and its accessories. The following are some application examples.

Using titanium as a structural material can enhance the service life of equipment, reduce equipment maintenance and control production losses. The harmful impurities such as iron in the products are reduced, resulting in a decrease in operating costs.

Containers with titanium linings can be used for evaporation (concentration), distillation, or reactions in weak acids or other chloride-containing solutions. Similarly, containers with titanium linings can be used for nitriding organic materials with nitric acid and for chemical reactions with other oxidizing media. Solutions containing chromic acid and chromic acid solutions undergoing sulfidation can be selected based on the required reaction temperature. In the chemical raw material industry, a certain application range has been verified that under catalytic oxidation conditions for carbon-chlorine compounds using copper and other gaseous solutions, it can be used as a catalyst when the pH value is determined. Then, at a temperature of approximately 150 to 200 °C, catalysis must be carried out with corresponding equipment. Containers with titanium linings can be used for towers, pipelines, valves, and acid pumps used for chemical reactions with other oxidizing media. Solutions containing chromic acid and chromic acid solutions undergoing sulfidation can be selected based on the reaction temperature requirements. In the chemical raw material industry, distillation towers are often used for purifying acetic acid, and most assembly components in the fractionation stages are made of titanium.

The spiral tube heater can prevent the formation of metal sulfates and has been tested to increase heat conduction by 30% compared to aluminum-coated copper spiral tube heaters. For urea reactors, to obtain (recover) carbon black and to eliminate stress, a reaction tower with a diameter of 43m and a length of 8.2m, capable of withstanding a temperature of 120 °C and a pressure of 130 kPa, is required. This reactor must reduce the pressure of gases and various other gases. This equipment is made of titanium.

At the same time, pumps, conduits, and heat exchangers made from welded titanium pipes have been tested and proven to be reliable and durable. Titanium plates are used to manufacture fine-grained seed plates for cathodes in electrolysis of copper.

The application of titanium has further expanded to the crude oil and petroleum processing industries.

Dehydration equipment for obtaining fresh water or drinking water from seawater or for organic acid production also use titanium. For example, in this regard, membrane evaporators made of coated titanium can be used.
