Chemical plants are generally divided into large and small chemical industry, large chemical industry refers to petrochemical, coal chemical industry, etc., are a lot of separation tower and so on; small chemical industry is generally the production of basic chemical raw materials, but also includes medical raw materials and drugs. Chemical plants are mostly built on water, often enough water can attract more chemical companies.
Because of the chemical industry's many categories, complex processes, and diverse products, the production of pollutants discharged in a variety of types, large quantities, and high toxicity, the chemical industry is a major polluter.
Extended Information
Chemical plant equipment used for chemical processing includes a wide variety of machines, tanks, and other components. They are stored, moved, and processed in a variety of ways from the time raw materials enter a process. One way to view important chemical plant equipment is through the main process stepsMeters that monitor chemical plant conditions and operate control valvesCan be powered by electricity or compressed airRaw materials can be transported by ship, truck or rail, such as liquids and solids.
They are typically stored in bulk material storage tanks, and warehouse storage is available in bags or drums. The materials eventually enter the process through feed tanks that store enough product to supply the reaction step, or bags of chemicals are added by hand The next step in the process is mixing and reaction products.
