1. Feedstock Quality: The quality of the feedstock can affect the overall efficiency and reliability of the facility. Therefore, the plant design should take into account the variability of the feedstock and the possible impurities that can affect the process.
2. Process Control: The process from waste-to-syngas-to-methanol-to-ethylene-to-polyethylene oxide-to-polyethylene glycol-to-polytrimethylene terephthalate is complex and requires precise process control. The plant design should include advanced process control systems to ensure high product quality, plant safety, and reduced downtime.
3. Energy Efficiency: The plant should be designed to optimize energy use and reduce cost. Considerations towards energy efficiency can range from heat recovery systems to renewable energy like onsite solar power plants.
4. Chemical Safety: Industrial chemicals are hazardous, and precautions should be taken to ensure plant personnel's safety, as well as the environment. Safety considerations like compliance with OSHA standards, Hazop studies, relief system design, etc., should be integrated into the plant design.
5. Cost Efficiency: Design considerations should include the cost of raw materials, process operating conditions, equipment sizing and selection, and product quality goals. A well-designed plant would strive to achieve the desired production at minimum cost.
6. Environmental Compliance: The environmental impact of any industrial facility is a growing concern, and its compliance is a critical design consideration. Designers should consider emission reduction technologies, Wastewater treatment facilities, and other environmental concerns while planning the plant layout.
7. Production Capacity: The plant's production capacity depends on product demand, and as such, the facility needs to be scalable. Good design must consider long-range market forecast and benchmark standards, the possibility of future expansion and upgrade.
8. Logistics: The site location must be accessible to necessary infrastructures such as water, electricity, natural gas, transport corridors, and skilled labour. The cost ratios and benefits of source efficiency can be identified, as necessary infrastructure across different areas can be varied.
