High Temperature Gas Purification Vessels
Roben, Mfg, Inc. manufactures high temperature gas purification vessels for removing contaminants from process gases at elevated temperatures. Our gas purification vessels feature designs optimized for hot gas filtration, catalytic cleanup, and sorbent-based purification where high-temperature operation improves efficiency or eliminates the need for gas cooling and reheating.
What Are High Temperature Gas Purification Vessels?
High temperature gas purification vessels are process equipment operating at temperatures from 700°F to 1800°F where particulates, sulfur compounds, chlorides, and other contaminants are removed from process gases. These vessels address applications where hot gas cleanup improves thermal efficiency compared to cooling gas for conventional purification.

Frequently Asked Questions
What contaminants can be removed by high-temperature gas purification?
High-temperature purification removes particulates using ceramic or sintered metal filters, sulfur compounds (H2S, COS) using zinc-based or rare earth sorbents, chlorides using sodium-based sorbents, and various trace contaminants using appropriate catalysts or adsorbents at elevated temperatures.
What filter materials operate at high temperatures?
High-temperature filtration uses ceramic candle filters (silicon carbide, alumina) to 1800°F, sintered metal elements to 1000-1400°F depending on alloy, and ceramic fiber elements for lower temperatures. Material selection considers gas composition, particulate loading, and cleaning method.
How are high-temperature gas purification vessels regenerated?
Filters are cleaned by periodic pulse cleaning with process gas or nitrogen. Sorbent beds may use thermal regeneration, oxidative regeneration, or replacement depending on sorbent type and contaminant loading. We design vessels with appropriate access and systems for the specified regeneration method.
