Coal gas purification facilities Design
Introduction
Coal gas purification is a process that is used to purify coal or other combustible gases. Through this process, combustible gases can be converted into non-combustible gases that meet the necessary environmental and health requirements established by the Environmental Protection Agency (EPA) or similar government agencies. Coal gasification is a process in which coal is heated in a pressurized chamber with water and oxygen to produce a gas that is significantly purer than the raw gas. In order to produce combustible gases, purified coal gas is typically sent to heaters where it is boiled off.
At the same time, it is important that the coal gas purification process is done in an efficient and cost-effective manner. If not done properly, the process can be expensive, as well as highly inefficient. In order to ensure that coal gas purification is done properly and effectively, certain facilities must be used.
Facilities
The facilities used for coal gas purification include:
Gas Preparation Plant: The gas preparation plant will prepare the gas for purification. It is typically the first step in the process and includes the operations necessary for safe and efficient transportation and storage of the fuel. Here, the fuel is first heated for optimal combustion, then filtered and dried for further treatment. This step is necessary both for safety and to ensure that the coal gas is of the highest quality.
Gas Scrubber: The gas scrubber is the main component in the coal gas purification process and is used to remove unwanted compounds and particles from the gas. It typically uses chemicals, such as acids and alkalis, to neutralize the gas. The chemical reaction causes the compounds and particles to become bonded together and eventually creates a sludge that can be safely and easily discharged.
Gas Coolers: Gas coolers are an important part of the process as they serve to cool the temperatures of the hot coal gas in order to prevent negative consequences of an overly hot coal gas. They are typically used when combustible gas is sent to heaters in order to reduce the temperature of the gas before it is put through the combustion process.
Gas Filters: Filters help to remove particulate matter from the coal gas, which is important for both the quality and purity of the coal gas, as well as for the safety of those who will be working with it. This step is important for adhering to environmental regulations and for preventing dust or other particles from entering certain components of the coal gas facility.
Conclusion
Chemical coal gas purification facilities are essential for the safe and efficient production of combustible gas from coal. These facilities are used to prepare the coal gas for purification, remove particulate matter and other contaminants, and cool the temperature of the gas before combustion. By using these facilities, companies can more effectively adhere to safety and environmental regulations while still providing combustible gas to their customers.
