The presence of hydrogen sulfide (H2S) in pulp and paper mills requires precise monitoring to ensure safety, efficiency, and environmental compliance. Therefore, proper analysis, in both the gas and liquid phases, is essential to avoid risks and optimize processes. Therefore, each step must be carefully monitored.
Gas phase analysis
During pulping, especially in pulp washers, sulfate-reducing bacteria can generate H2S. Furthermore, in digesters, which break down wood chips into pulp, gas can also form.
Another critical point is recovery boilers, where H2S can occur when recovering chemicals and energy from black liquor. In wastewater treatment, anaerobic digestion can release the gas into the biogas produced. Consequently, a reliable detection system is required.
To meet this demand, Keco offers the T200 and Sulfur Hound models , both designed to ensure precise results. This way, the operation maintains high safety standards and environmental compliance.
T200
The T200 ensures accurate and reliable measurement. It does not generate false positives, and also features automatic auto-zero function, automatic calibration, diagnostic alarm, and compliance with ASTM methods. Therefore, it is suitable for processes that require rigorous control.
- Never generates “false positives”
- Automatic autozero function
- Fault diagnosis relay alarm
- Compliance with ASTM methods
- Automatic calibration
Sulfur Hound
The Sulfur Hound measures H2S in natural gas, biogas, and air, making it ideal for hazardous locations (Division 2 and Zone 2). Furthermore, its maintenance is reduced as it does not use paper strips, solutions, or scrubbers. This minimizes downtime, increasing productivity.
- Measures H2S in natural gas, biogas, air, etc.
- Designed for Division 2 and Zone 2 hazardous locations
- Low maintenance with few moving parts
- Does not use paper tapes, solutions or scrubbers
Liquid phase analysis
H2S can also dissolve in effluent streams, especially under anaerobic conditions. Chemical storage tanks, especially those containing sulfur-based products, are another point of concern. Continuous monitoring is essential to avoid risks.
For these situations, Keco offers the K-205-Permastream , which guarantees real-time measurement of H2S in crude oil, water, and diesel. It is specific for H2S, with no false positives, and does not require field calibration or sample filters. Additionally, it offers fast response time and direct installation in the process line, optimizing operation.
