Gasifier Monitoring System
Sample conditioning and gas analysis for challenging raw coal gas containing tar, dust and moisture.

The gasifier solution addresses high-pressure raw gas with tar, dust, acidic components and moisture. Sample conditioning is designed around the actual process composition and conditions.
The supplied HN-LQL-X material lists options for O₂, CO, CO₂, H₂S, CH₄ and H₂. Select the gas list and analytical method around the process duty.
Pressure ratings, hazardous-area requirements, utilities, drainage and alarm responsibilities require a project-specific review.
