The pulp mill environment is tough; its dirty, its humid, it poses safety risks to personnel, facility, & equipment. There are serious concerns about fire and explosions but also sample delivery and maintennce. You need a reliable monitoring system.
Most monitoring systems are only able to measure the percent of flammability of a specific gas or narrow family of gases. In pulping applications, however, it is necessary to measure the overall concentration of all flammable gases and vapors entering the incinerator.
Using an analyzer with high sampling speed dramatically improves response time - an important factor in pulp mill applications.
The environment of the vent pipe that carries the Total Reduced Sulfur compounds (TRS) is dirty and humid. Most gas sensors are quickly impaired by these conditions, leading to unreliable readings.
Because most sensors can only operate at ambient, as opposed to process temperatures, they are positioned far away from incinerators, using a snaking pipe arrangement and pumps to cool samples.
