Although concerns about severe oversupply and sluggish earnings have plagued ethylene glycol producers for a long time, in the long run, the market still has enough potential demand to support the growth of the industry. London-based Tecnon OrbiChem Company recently stated that the annual capacity of the global ethylene glycol market will exceed 3.5 million tons this year; the surplus will drop below 3 million tons by 2012, and further reduce to 2 million tons by 2015; By 2017, the global ethylene glycol consumption is expected to exceed the capacity of nearly 1 million tons if calculated at 90% of the operating rate. According to Tecnon OrbiChem, by 2017, the excess capacity in the global ethylene glycol market may not be worth worrying because some temporary shutdowns will ease the excess capacity in the market, especially in Taiwan, South Korea and other places. Some ethylene glycol producers in the United States and Europe have announced rationalization of capacity. Dow Chemical's facility in Taft, Louisiana, will convert ethylene oxide later this year. It will also permanently shut down an unused glycol unit in the area, while Dow Chemical's in Wilton, UK. A set of glycol devices has been closed in January this year.
Electric valve is a device that drives the valve to open and close by electric motor. It is widely used in various industrial and civil fields, such as metallurgy, chemical industry, petroleum, natural gas, heating, ventilation and air conditioning, automatic control, etc. The following are some application scenarios of electric valves:
1. Fluid control in industrial production: electric valve can be used to control the flow, pressure and temperature of liquid, gas and steam to meet the needs of industrial production.
2. Oil and natural gas industry: electric valves can be used in oil and natural gas exploitation, processing, transmission and storage to control flow and pressure and ensure production safety and efficiency.
3. Chemical industry: electric valve can be used for fluid control in chemical production, such as acid-base solution, gas and liquid reactant control, to ensure the safety and efficiency of production.
4. Heating, ventilation and air conditioning system: the electric valve can be used to control the water flow, air flow and temperature in the heating, ventilation and air conditioning system to meet the requirements of the indoor environment.
5. Automatic control system: electric valve can be used with automatic control system to realize automatic control and adjustment of fluid flow, pressure, temperature and other parameters.
In short, electric valves are widely used in industrial and civil fields, which can improve production efficiency, ensure product quality and improve production safety.
