Shanghai ZEPU Gasification Solution

Technical Features

Wide Feedstock Flexibility, Minimal Pretreatment

The gasification process can handle a wide range of feedstocks, including lignite, bituminous coal, low-grade coal, biomass, and carbon-containing wastes.
Dry, pressurized, particulate feed
Feed size: Approximately 8 mm
Upstream feed pretreatment is simple and cost-effective

Feed Capacity > 2,000 t/d

Each gasifier can process over 2,000 t/d, enabling large-scale, efficient operations. Higher single-furnace capacity reduces the number of units required, minimizing overall investment.

Flexible Gasification Pressure

ZP gasifiers operate at pressures from 2 to over 40 barg, tailored to gas demand and downstream requirements. This reduces the need for syngas compressors and minimizes equipment maintenance, enhancing efficiency and reliability.

Tar-Free Syngas

ZP gasifiers operate at around 1,000 °C, where the high-temperature core and elevated bed fully convert volatiles and tars into clean, valuable syngas (CO, H₂, CH₄) — completely tar-free, even for biomass feedstocks.

Carbon Conversion > 98%

ZP gasifiers utilize a high-temperature central reaction zone with fine recirculation, achieving >98% carbon conversion. Compared to conventional fluidized bed gasifiers, feedstock consumption is reduced by 15–20%, slag carbon <5%, and cold gas efficiency >80%, delivering highly efficient and economical operations.

Extremely Low Emissions

ZP gasifiers feature dry ash removal and waste heat recovery, producing minimal solid, liquid, and gas emissions. Wastewater requires only simple ammonia stripping, making the process eco-friendly, cost-effective, and easy to operate.

Safe, Eco-Friendly, Efficiency

ZP gasifiers follow strict petrochemical safety standards, ensuring reliable and secure operation. High-temperature syngas waste heat is recovered directly through boilers, producing high-quality steam and maximizing energy efficiency.

Reliable, No Standby Gasifier

ZP gasifiers deliver consistent, reliable operation, with large-scale units achieving over 95% annual uptime, eliminating the need for standby gasifier.
