According to Tecnon's estimation, the global demand for acrylonitrile will increase at an average annual rate of 2% to 2.5% in the next few years. The demand for acrylonitrile fibers will remain stable, and demand from the ABS market will increase at an average annual rate of 5%. The speed will increase, and the demand for acrylamide will increase at an average annual rate of 6% to 7%.
Analysts said that the high cost of raw materials and China's new production capacity of acrylonitrile fibers have prompted production capacity in Europe and Japan to close down on a larger scale. In 2005, the global shutdown of acrylonitrile production capacity is more than the new production capacity.
According to statistics, in 2005, approximately 420,000 tons/year of acrylonitrile production capacity was shut down globally, and the new capacity was 316,000 tons/year. Sterling Chemical Company shut down the 360,000-ton/year plant in the United States in 2005 and withdrew from the acrylonitrile business. Mitsui Chemicals also closed the 60,000-ton/year facility in Osaka, Japan, in May 2005. In the third quarter of 2005, Lucite International closed its 4.5-million-ton facility in Texas. At the same time, BP's 260,000-ton/year acrylonitrile plant in China was put into production in July 2005. Innovene also increased the capacity of the acrylonitrile plant in Cologne, Germany, to 60,000 tons/year to 35.5 in December 2005. 10,000 tons/year. Analysts believe that as long as crude oil and propylene prices remain high, profit pressure on the acrylonitrile-acrylonitrile fiber industry chain will remain.
One of the highlights of the current acrylonitrile industry is the development of a new process for acrylonitrile production from propane. It is reported that this process will reduce the production cost of propylene ammoxidation process, which is the mainstream process of the current acrylonitrile industry, by 30%, thereby enhancing the competitiveness of downstream products. Asahi Kasei Corporation recently announced that it has signed an agreement with Thailand's PTT Chemical Co., Ltd. to plan production of acrylonitrile in Thailand using this new process.
A Heat Exchanger is a device designed to efficiently transfer or "exchange" heat from one matter to another. When a fluid is used to transfer heat, the fluid could be a liquid, such as water or oil, or could be moving air. The most well known type of heat exchanger is a car radiator. In a radiator, a solution of water and ethylene glycol, also known as antifreeze, transfers heat from the engine to the radiator and then from the radiator to the ambient air flowing through it. This process helps to keep a car's engine from overheating. Similarly, our heat exchangers are designed to remove excess heat from aircraft engines, optics, x-ray tubes, lasers, power supplies, military equipment, and many other types of equipment that require cooling beyond what air-cooled heat sinks can provide.
There are various types of heat exchangers. our heat exchangers provide air-to-liquid cooling, liquid-to-air cooling, liquid-to-liquid cooling, or air-to-air cooling. With air-to-liquid cooling, heat is transferred from the air to a liquid. One example of air-to-liquid cooling is cabinet cooling. With liquid-to-air cooling, the heat is transferred from the liquid to the air. This type of cooling is generally used to cool process fluids. Liquid-to-liquid cooling is also used to cool process fluids, but the heat is removed by another liquid instead of by air. Lastly, with air-to-air cooling, heat is transferred from one air or gas stream to another.
we has been manufacturing one of the most widely used heat exchanger technologies, tube and fin heat exchangers, for more than 20 years. Tube and fin heat exchangers provide air-to-liquid cooling or liquid-to-air cooling. They consist of fin, hairpin tubes, return bends to connect the hairpins, a tube sheet to support and properly align the tubes, a header with inlets and outlets, side plates for structural support, and usually a fan plate. The tubes provide the path for the liquid coolant, and the fin adds surface area for more heat convection. Copper is often selected for tube and fin material due to its excellent thermal conductivity and compatibility with water and ethylene glycol solutions. However, stainless steel is used for tube and fin when it's necessary for the coolant to be deionized water or other corrosive fluids.
