1. Feedstock selection and preparation: The selection of feedstock is vital as it determines the efficiency of the process. The feedstock must be prepared to ensure that it meets the required specifications for feed into the gasifier.
2. Gasification technology: The gasification technology used to convert solid waste into syngas should be chosen based on its efficiency, cost, and environmental impact. The technology chosen should be able to handle the feedstock selected for the facility.
3. Syngas purification: The syngas produced in the gasifier must be purified to remove impurities such as CO2, H2S, and tars, which can cause downstream problems in the process.
4. Chemical synthesis technology: The chemical synthesis technology used to produce methanol, acetic acid, butyl acetate, and acetone should be chosen based on its efficiency, cost, and environmental impact.
5. Catalyst selection: The choice of catalysts or reactions promoters used for the synthesis of the chemicals is another important consideration in the facility design.
6. Waste management system: The waste produced during the process must be handled and disposed of safely, and this should be factored in the design of the facility.
7. Process control system: The process control system must be designed to ensure that all parameters are monitored and controlled to optimize the process, improve efficiency and productivity.
8. Energy recovery system: Energy recovery systems such as cogeneration, heat recovery, or heat integration systems may be necessary to improve the energy efficiency of the process and minimize the environmental impact of the plant.
