PYROLYSIS AND ENERGY-FROM-WASTE
WASTE-TO-ENERGY SYSTEMS
High-efficiency fuel & energy production
Efficient reduction of waste feedstocks into liquid and gaseous fuels for storage, onward processing or direct generation of electrical energy from waste.
FuturEnergy waste to energy plants provide recycling of wastes into highly valuable liquid, gaseous and solid fuels and other products using pyrolysis. Wastes as diverse as end-of-life tyres, mixed plastics, or other organics can be turned into valuable alternative energy and chemical supply solutions.
TECHNOLOGY INTRODUCTION
All systems comprise of a series of discrete modules integrated into a whole design to reduce a variety of raw feedstock materials into base compounds. Wherever possible multiple flow paths are adopted to prevent process pinch-points and single points of failure.
Pyrolyser
Waste feedstock: end-of-life tyres
Temperature: subject to feedstock, 450°C to 600°C
System objective:
Reduction and disposal of waste (end of life certification)
Production of high quality stable oils and combustible gases
Production of high-quality recovered carbon black (rCB)
Direct use of oil in IC generator sets with electricity export
Direct use of combustible gases in gas IC generator sets with electricity export
Chars suitable for use in chemical processes or co-firing units
Storage of oils for onward processing (option)
Sizes: Modules based on rubber waste at ~1t/hr throughput, (multiple modules share common equipment)
Typical equipment:
• Materials handling systems comprising pumps, feed-screws, conveyors, storage hoppers
• Input hopper feed system (with weight loss monitoring to manage throughput)
• Nitrogen inerting system comprising generator, storage and delivery
• Materials pre-treatment and separation (subject to waste type)
• Pyrolysis chambers
• Heat exchangers, heat recovery and recirculation systems
• Char extraction and cooling systems
• Vapour condensers, gas filters, gas scrubbers, and gas pressure buffer (where required)
• Oil fractionation system (subject to system objective)
• Flare system
• Overarching control system
• Cooling modules with air blast cooler/chiller
• Oil storage units
• Char handling, packing and storage systems
• Oil or gas IC engines
• Grid connection facilities
