I’m setting up a pilot project that converts agricultural biomass into liquid bio-oil and I need a compact pyrolysis system engineered, fabricated, and ready to run. The target throughput is strictly small-scale—no more than 100 kg of feedstock per day—so I’m after an efficient, bench-to-plant solution rather than a full-blown industrial line. Here’s what I’m counting on you to handle from concept to commissioning: • Process design sized for ≤ 100 kg/day of mixed biomass • Detailed mechanical drawings, P&ID, and a complete bill of materials • Fabrication or clear fabrication instructions for reactor, condenser train, and ancillary equipment • Integrated heating and basic control scheme (PLC or Arduino-based is fine as long as temperature is held reliably) • Factory acceptance test showing steady production of bio-oil, plus a short run-up guide I can follow on site Key points you should factor in: fast or slow pyrolysis is acceptable as long as bio-oil yield is maximized; char and syngas can be considered by-products but don’t need dedicated upgrading; footprint must stay compact enough to fit inside a standard 20 ft container or modular skid. If you’ve already built similar small pyrolysis or waste-to-energy units, point me to them so I can gauge fit. I’m ready to move quickly once we agree on a practical timeline for design, build, and shipping.

Hello, I have 15+ years of experience in mechanical engineering, product design, and process engineering, and I am a licensed professional engineer. Your project—to design and deliver a compact, efficient biomass pyrolysis unit for producing bio-oil from agricultural feedstock—matches well with my background in developing small-scale waste-to-energy systems and modular process equipment. > I will design the full pyrolysis process with a capacity of up to 100 kg/day, focusing on maximizing bio-oil yield while keeping the system compact. > I will provide detailed mechanical drawings, P&ID, and a complete bill of materials to support fabrication and assembly. > I will deliver fabrication-ready instructions for the reactor, condenser system, and all ancillary equipment, ensuring straightforward construction. > I will integrate a reliable heating and control system (PLC or Arduino-based as you prefer), and supply a short run-up and commissioning guide, plus factory acceptance test results. Previously, I developed bench-scale pyrolysis and gasification units for university research and pilot commercial projects, with emphasis on efficient thermal control and compact layout. Could you confirm whether you have a preferred type of biomass feedstock or expect a wide variety of materials? Please contact me. Best Regards, Sutton

Hi, Thank you for sharing the details of your biomass pyrolysis pilot project. I understand you need a compact, efficient system to convert agricultural residues into high-yield bio-oil—complete with process design, mechanical drawings, a robust control scheme, and commissioning support, all within a modular footprint. I’m confident I can deliver exactly what you’re after. I have hands-on experience designing and commissioning small-scale pyrolysis and waste-to-energy units for both research and commercial pilots. For example, I recently led a project delivering a 50 kg/day batch pyrolysis unit for a university client, handling everything from SolidWorks modeling and P&ID to PLC integration and field testing. My approach always emphasizes practical fabrication, reliable temperature control, and clear documentation to ensure smooth handover and operation. For your project, I’ll tailor the system—whether fast or slow pyrolysis—to maximize bio-oil yield while maintaining a compact, easy-to-install layout. I’m comfortable working with both PLC and Arduino-based control, ensuring steady operation and user-friendly monitoring. I can provide photos and references from similar builds if helpful. - Complete process design for ≤100 kg/day biomass, with detailed mechanical drawings and P&ID - Full bill of materials and clear fabrication instructions for the reactor, condenser, and ancillary systems - Integrated heating and control solution ensuring precise temperature management - Factory acceptance test with bio-oil production demonstration, plus a concise operation and commissioning guide I am excited by the prospect of supporting your innovative pilot and am confident I can deliver a solution that meets your needs. Let’s discuss your feedstock specifics and move this project forward. I look forward to working with you. Best Regards, David

Hello, I’m very interested in your biomass-to-bio-oil pilot project and have experience with thermal process systems, process equipment design, controls integration, and fabrication documentation for small-scale industrial applications. Your target throughput of less than 100 kg/day is well suited to a compact pilot-scale system that emphasizes process reliability, safety, and bio-oil yield optimization. I can support the project from concept through commissioning, including process design, reactor sizing, P&ID development, mechanical fabrication drawings, BOM preparation, instrumentation selection, and control system integration. Depending on your feedstock characteristics and desired product distribution, I can evaluate both fast and slow pyrolysis approaches and recommend the configuration that maximizes liquid yield while maintaining a practical footprint suitable for containerized or skid-mounted deployment. The deliverables can include complete fabrication packages for the reactor, condensers, gas handling, feed system, and support equipment, along with PLC or Arduino-based temperature control capable of maintaining stable operating conditions. I can also provide startup procedures, operating guidelines, safety recommendations, and factory acceptance testing documentation demonstrating system performance prior to shipment. I look forward to discussing your requirements and helping bring this pilot system from concept to operation. Best regards,

Hello, Your project is exactly the type of pilot-scale engineering challenge I enjoy working on. I have experience developing compact process systems that bridge the gap between laboratory concepts and practical field deployment, with a strong focus on manufacturability, control reliability, and ease of operation. For a biomass throughput of up to 100 kg/day, I would propose a container-friendly pyrolysis platform designed around efficient thermal conversion, robust condensation, and straightforward maintenance. The objective would be to maximize bio-oil production while keeping the system compact, energy-efficient, and simple to operate. I can develop the complete engineering package, including process flow diagrams, P&IDs, mechanical fabrication drawings, equipment layouts, instrumentation schedules, and a detailed bill of materials. The system can be equipped with automated temperature monitoring and control using either a PLC or Arduino-based architecture, depending on your budget and operational preferences. I can also provide fabrication guidance, assembly documentation, commissioning procedures, operating manuals, and factory acceptance testing protocols to verify stable operation and repeatable bio-oil production before shipment. Thank you for your consideration. I look forward to learning more about your project. Best regards,

Char and syngas will be produced as by-products. Our scope covers full engineering design, fabrication drawings, equipment supply, assembly, testing, and factory acceptance testing to confirm steady bio-oil production before delivery. We will also provide commissioning support and an on-site startup guide. The project will be delivered in phases: design, fabrication, testing, and commissioning, with focus on a compact, reliable, pilot-scale system.
