1. Site selection: A suitable location should be chosen that is close to the source of waste and has adequate access to transportation and infrastructure.
2. Scale of operation: The size of the facility should be determined based on the amount of waste generated and the production capacity required.
3. Input feedstock: The composition of waste that will be used as feedstock needs to be assessed to ensure that it is suitable for hydrothermal liquefaction.
4. Process design: The process design should be optimized for the specific feedstock, and considerations should be given to avoid fouling, corrosion, scaling, and other operational issues.
5. Equipment selection: The selection of equipment, such as reactors, heat exchangers, pumps, and compressors, should be based on their suitability for processing the feedstock and handling high-temperature and high-pressure environments.
6. Safety and environmental compliance: The facility should comply with all safety and environmental regulations, including emissions, effluent and waste disposal, and prevention of accidental exposure to hazardous materials.
7. Energy efficiency: The facility should be designed to minimize energy consumption and optimize energy recovery.
8. Waste management: The facility should have adequate systems for handling waste generated during the process, such as solid residue and wastewater.
9. Product quality: The design should ensure that the final products meet the required quality standards and can be sold at competitive prices.
10. Operational and maintenance considerations: The facility should be designed in a modular and flexible manner to optimize operational efficiency and minimize maintenance costs.
