1. Feedstock selection: The selection of feedstock is a critical design consideration in waste-to-syngas facilities. Various types of waste are used as a feedstock such as biomass, municipal solid waste, industrial waste, and wastewater sludge. The feedstock selection must be based on several factors such as the availability of waste, the quantity of waste produced, and the economics of the waste.
2. Gasification technology: There are various technologies available for gasification of waste such as downdraft gasification, plasma gasification, and fluidized bed gasification. The selection of gasification technology should be based on several factors like feedstock characteristics, operating conditions, and gas composition requirements.
3. Syngas cleaning and conditioning: Syngas cleaning and conditioning is a crucial design consideration to remove impurities such as sulfur, nitrogen oxides, and tar. Depending on the application, the gas needs to be conditioned to meet certain quality specifications.
4. Environmental regulations: Industrial waste-to-syngas facilities must comply with relevant environmental regulations. The facility must maintain safe operating conditions, while also minimizing environmental impact and complying with emission limits.
5. Heat integration: Heat integration is another design consideration for industrial waste-to-syngas facilities. The energy generated from waste can be used for various applications such as electricity generation, steam production, and hot water production. The facility must be designed for efficient heat transfer and energy utilization.
6. System reliability: The reliability of the facility is essential as any downtime can lead to significant financial losses. The design should be reliable, and backups systems should be implemented to ensure continuous operation.
7. Economic considerations: Economic considerations such as capital and operating costs, as well as market conditions, must be considered during the design phase. The facility should be designed for optimal energy recovery and efficiency to minimize operating costs.
