Titanium heat exchangers OPEX and their scope
Titanium is a lightweight, silvery-white, tough metal. For the first time titanium was discovered at the end of the 18th century, and already at the beginning of the 19th they received the first sample of metallic titanium. The heat exchange surface made of titanium is usually used with environments with increased corrosive activity and aggressiveness. Titanium is resistant to corrosion, due to the formation of an oxide film, solutions of most alkalis, acids, chlorine. Another big advantage of titanium is its weight. Compared to steel, titanium is almost twice as light and is not inferior in strength.
The active use of titanium is observed in:
Shipbuilding - gasketed plate heat exchangers are widely used as an engine oil cooler, in seawater desalination plants, as a seawater condenser. The use of titanium is explained by the fact that sea water is slightly alkaline, contains dissolved NaCl salt, on average 3-7%, this has a destructive effect on any nickel-containing stainless steel. The use of gasketed heat exchangers with titanium heat exchange surface is the most profitable and practical.
Oil and gas production - a large number of heat exchangers are used in oil fields, in installations for heating, cooling and heat recovery during the preparation of commercial oil. The use of welded plate heat exchangers is widely used to cool the associated gas before feeding it to the compressor. Since the gas flows at a high pressure, above 30 bar, the welded apparatus perfectly copes with this task.
Oil and gas industry - in the processes of dehydration and desalting of crude oil, in the processes of amine gas purification, as a saturated amine heater, for stabilization of crude oil, in catalytic cracking units.
Petrochemical and chemical industries - in the processes of heat recovery from production: aldehydes, acids, ethers, potassium, magnesium, soda, sodium, organic glass, pharmaceutical products, etc.
Metallurgical industry - the use of plate heat exchangers is widely used to extract heat from circulating water containing a huge amount of aggressive impurities.
Food industry - in the production of food products containing edible salt. Titanium heat exchangers are often used in dairy factories in the cheese production process. The NaCl content in water can reach 20-30%.
The household sphere - even in everyday life, a titanium heat exchange surface has found its application. An example would be the heating of water for swimming pools. For the sake of high sanitary standards, fluoride, chlorine and salt are added to the water. The high content of such elements destroys the stainless steel surface of the heat exchanger.
Since 1999, OPEKS Energosystems has started supplying titanium heat exchangers . Several large projects have been implemented for the installation of gasketed plate heat exchangers for metallurgical enterprises. The tasks of removing heat from cooling water containing a large amount of chlorine ions have been implemented. Heat exchangers were supplied for Ukrainian dairy enterprises to recover heat from brine. On ships, shipbuilding and ship repair yards, THERMAKS heat exchangers operate with salt sea water. Delivered titanium heat exchangers for heating seawater for swimming pools in recreation areas. Titanium heat exchangers from OPEKS are a practical and durable solution for processes with aggressive media.
