Gasification & Chemical Recycling
Gasification is emerging as a key technology in the transition toward a circular low carbon economy.
Advanced Materials Handling for Circular Low Carbon Processes
Modern recycling facilities are converting end-of-life plastics, woody biomass and various waste feedstocks into syngas, hydrogen, fuels, sustainable aviation fuel (SAF) and chemical feedstocks.
These advanced processes require robust materials-handling systems capable of feeding challenging solid materials into high-temperature, pressurised reactors.
Clyde Pneumatic Conveying specialises in this critical part of the process. Our technologies provide the reliable handling, conveying and injection of recycled carbon materials, forming the essential link between upstream material preparation and the gasification reactor.
Clyde is one of the few companies globally with proven experience in injecting solid materials into pressurised process environments, making us a trusted partner for advanced recycling and gasification projects.
Materials Handled
Gasification and chemical recycling plants must handle a wide range of materials. Clyde systems have extensive experience conveying and injecting materials, including:
- End-of-life plastic pellets
- Plastic flakes and granulates
- Refuse-derived fuels (RDF)
- Solid recovered fuel (SRF)
- Woody biomass and wood chips
- Biomass pellets
- Process residues and char
- Municipal Solid Waste (MSW)
- Recycling streams from advanced materials recovery plants
These materials often present irregular particle shapes, varying bulk densities and inconsistent compositions, requiring specialised handling technologies.
Injection into Pressurised Gasifiers
One of the key engineering challenges in gasification plants is feeding solid materials into reactors operating at elevated pressure and temperature.
Clyde provides high-integrity injection systems designed to reliably introduce these materials into the process while maintaining full pressure containment.
Our systems combine precision feeding devices, dense-phase conveying, and lock-vessel technology to deliver controlled material flow directly into the gasifier.
For example:
- Woody biomass can be injected into pressurised gasifiers with particle sizes up to approximately 25 mm.
- End-of-life plastic pellets can be conveyed and injected into reactors operating at several bar pressure and temperatures exceeding 600°C.
These systems ensure stable reactor feeding, safe pressure containment and reliable plant operation.
Key Technologies for Gasification Plants
Clyde solutions combine several proven technologies designed specifically for recycling and gasification processes.
Precision Feeding Systems
Our ROTOFeed and ROTOScrew technologies provide accurate, controlled feeding of irregular materials, such as shredded plastics and biomass.
These systems are designed to accommodate non-uniform particle sizes while maintaining stable and consistent feed rates.
Dense Phase Conveying
Pressure let down and Dense phase conveying enables materials to be transported using low gas velocities, reducing:
- Pipe wear
- Material degradation
- Dust generation
This makes the technology particularly suitable for fragile biomass materials, recycled plastics and high temperature gasifer and filter residues.
High Integrity Isolation Valves
Clyde's Dome Valve technology provides reliable isolation within pressurised systems, ensuring:
- Gas-tight sealing
- Long operational life
- Safe integration with reactor systems
Reliable Operation in Demanding Environments
Gasification plants typically operate continuously, 24 hours per day, requiring extremely high equipment reliability.
Clyde systems are engineered to deliver:
- Continuous reactor feeding
- Stable process control
- Minimal maintenance requirements
- ATEX-compliant designs were required
Our technologies are based on decades of experience handling difficult materials across energy, metals and recycling industries.
Supporting the Circular Carbon Economy
Gasification and chemical recycling technologies are playing an increasingly important role in:
- Converting waste plastics into new chemical feedstocks
- Producing renewable fuels from biomass
- Generating hydrogen and syngas for low-carbon industries
Clyde Pneumatic Conveying provides specialised materials-handling systems that enable these processes, ensuring the reliable feeding of solid materials into the heart of the gasification reactor.
