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.

Hi there, I can design a compact biomass pyrolysis system for up to 100 kg/day, including process design, P&ID, mechanical drawings, BOM, control system, and fabrication documentation. I'll optimize the reactor and condenser system for maximum bio-oil yield while ensuring the unit fits within a standard 20-ft container or skid. I have experience with thermal process equipment, mechanical design, and pilot-scale systems, and can support the project from design through fabrication and commissioning. Best Regards,

Hello, Your project is very interesting and aligns well with my experience in process engineering, thermal systems, and pilot-scale equipment development. I can assist with the complete development of a compact biomass pyrolysis unit, including process design, reactor and condenser sizing, P&ID creation, mechanical drawings, BOM preparation, control system integration, and commissioning support. The focus would be on maximizing bio-oil yield while maintaining a compact footprint suitable for a containerized or skid-mounted installation. My approach would include: • Feedstock and process evaluation • Reactor, heating, and condenser system design • Detailed CAD drawings and fabrication package • PLC or Arduino-based temperature control system • Equipment specifications and procurement support • FAT testing procedures and operating documentation I understand the challenges involved in heat transfer, vapor residence time, condensation efficiency, and bio-oil recovery, all of which are critical to achieving reliable performance at the 100 kg/day scale. Please share any preferred feedstock types, target bio-oil yields, and project timeline. I would be happy to discuss the design strategy and next steps. Best regards,

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,
