Chemical process plants produce a range of chemicals and products through various unit operations. Raw materials are inputted, and output can refer to completed products or matter leaving a specific unit. Chemical engineers design and maintain these plants, taking into consideration safety and varying factors such as temperature and location. Chemical engineers are also important in finding new ways to work more effectively and efficiently.
A chemical process plant is an industrial environment where chemicals can be produced. In some plants, existing chemicals are transformed into new materials. The range of chemicals and products manufactured in such facilities is extensive. Several chemical processes are often required.
The process employed in a chemical processing plant normally involves steps known as unit operations. Each unit operation is usually performed in a separate unit, or area, of the chemical process plant. Units are generally linked together so that materials can be transported to the next unit at the end of each operation.
Chemicals and chemical-based products have to come from other things. The first unit operation in a chemical process plant is usually the input of raw materials, also known as raw materials. A feedstock not only refers to the raw materials that are introduced into the process, but can also refer to material that is going into a particular unit.
Output in a chemical process plant can refer to matter that has completed a unit operation and is leaving a specific unit. It can also refer to matter that has completed the entire chemical process and is ready to leave the plant. A completed product or chemical in a chemical process plant may still be only in its early stages. Production from one plant is often feedstock for another.
The unit operations that occur between raw material input and final output vary. The approach taken will largely depend on what is being produced. Even within a general area of chemical processing, such as petrochemical manufacturing, processes can vary widely.
The facilities where these chemical processes are employed are usually designed by chemical engineers. Building a chemical process plant is not as simple as hiring people to erect the structure and connect pipes and electricity. Unlike other facilities, such as retail or office buildings, there is much more consideration that needs to be taken with chemical process plants.
The raw materials and production of these industrial plants can be dangerous or toxic. If the chemical process is not adequately contained, serious damage to the environment or to human and animal health could occur. To ensure safety, chemical engineers need to evaluate how certain chemical processes will affect the materials they interact with. Chemical engineers also need to evaluate the setup that will allow the chemical process to achieve its goals.
Because the chemical processes employed vary and the desired outputs vary, there is no standard chemical process plant. Designs often differ based on a number of factors, including temperature and location. Maintaining a certain temperature can be very important in a chemical processing plant. In hotter areas, for example, cooling may be a primary design focus.
Most chemical process plants have chemical engineers on their staff even once the plant is built. As in any business, people who manage a chemical processing plant tend to continually look for new ways to work more effectively and efficiently. Chemical engineers are important in this respect. They are also essential to maintaining the infrastructure of the chemical process plant.
