Design of Coke Oven Gas Purification Facilities
Today, coke oven plants are important components of the steel industry, and their emissions contain flue gas, sulfur dioxide, soot, phosphorus and other industrial pollutants, necessitating purification before they can be discharged into the atmosphere. This article discusses the design of coke oven gas purification systems, including the type of equipment used, their placement and configuration, the specific parameters and installation requirements, the influent and effluent levels, safety considerations, and the expected level of performance.
The first step in designing a system for purifying coke oven gas is to determine the required inlet and outlet parameters. This includes measuring the characteristics of the inlet gas, such as temperature, humidity, and sulfur and nitrogen oxide levels. Based on these measurements, the appropriate equipment and configuration can be selected. In general, coking plants require systems for particulate removal, sulfur and nitrogen removal, and condensation of water vapor. The choice of equipment is determined by the expected inlet and outlet parameters, as well as the size and capacity of the plant.
The equipment is typically installed in a power plant, a steel plant, or a chemical plant. It should be installed in an area with good ventilation and adequate room for all of the necessary components and fittings. In most cases, the placement of the equipment is determined by the size of the plant and the ease of access.
The equipment used to purify coke oven gas generally consists of filtration and adsorption systems, such as pleated cartridges, scrubbers, cyclones, and activated carbon filters. The specific type of equipment selected will depend on the size and composition of the inlet gas as well as the end product desired. In order to optimize the efficiency of the process, the configuration of the equipment should be determined before installation.
The influent and effluent levels should be specified before installation. This includes the levels of sulfur, nitrogen and particulate matter that should be present in the inlet gas, as well as the desired levels in the outlet gas. The levels specified should be achievable with the equipment selected.
Safety is always a paramount consideration in the design of any industrial system. Coke oven gas purification systems should adhere to all applicable codes and regulations governing their use, as well as any safety precautions necessary to minimize the risk of fire or other hazards. The equipment should also be designed with an appropriate level of redundancy to minimize the impact of any potential failure.
The expected level of performance is another important factor to consider. The efficiency of the system should be taken into account when selecting the equipment, as well as when determining the influent and effluent levels. The system should be designed to meet the desired standards in terms of effluent quality and compliance with applicable laws and regulations.
In summary, the design of a coke oven gas purification system must take into account the type of equipment used, its placement and configuration, the specific parameters and installation requirements, the influent and effluent levels, safety considerations, and the expected level of performance. By taking the time to consider all of these factors during the design process, the system can be optimized to ensure adequate purification of the inlet gases and long-term compliance with all applicable regulations.
