Gasification Process Vessels
Roben, Mfg, Inc. engineers and fabricates gasification process vessels for converting carbonaceous feedstocks into synthesis gas at high temperatures. Our gasification vessels feature refractory protection, high-temperature materials, and designs accommodating the extreme conditions of partial oxidation processes used in coal, biomass, and waste gasification.
What Are Gasification Process Vessels?
Gasification process vessels are high-temperature reactors where carbon-containing feedstocks (coal, biomass, waste) undergo partial oxidation at temperatures from 1400°F to 2800°F to produce synthesis gas (primarily CO and H2). These vessels incorporate refractory linings, slag handling provisions, and designs for the demanding thermal and chemical conditions of gasification.

Frequently Asked Questions
What temperatures do gasification vessels operate at?
Gasification temperatures depend on feedstock and process: fixed bed gasifiers operate at 1200-1800°F, fluidized bed at 1500-1900°F, and entrained flow gasifiers at 2300-2800°F (slagging conditions). We design vessels for specific gasification technology requirements.
How do refractory systems protect gasification vessel shells?
Gasification vessel refractories typically include multiple layers: dense working lining resistant to slag and syngas, insulating backup layers, and shell-side protection. Some designs use water-cooled membrane walls instead of or in addition to refractories. Refractory selection considers slag chemistry and operating temperature.
What provisions address slag in gasification vessels?
Slagging gasifiers include slag tap holes, slag quench systems, and designs enabling controlled slag removal. We design for slag flow at operating temperatures and include provisions for periodic slag tap rodding or cleaning. Non-slagging gasifiers require different ash handling approaches.
