Procal Analytics’ PULSI 200LR has been selected by a company in the US to monitor emissions from the pulp mill. This represents a growing market for Procal Analytics, whose instruments are designed, not only to meet local environmental legislation as in this case US EPA 40CFR part 60, but also because of the very low maintenance requirements. This was a key factor in the selection of the PULSI 200LR by the company.

Often, pulp mills are in remote areas, therefore any maintenance or service of the instrument can be relatively expensive. The PULSI 200LR has been designed to reduce the need for maintenance by ensuring MTBF of all components is high, for example, the life of the infra-red source is counted in years and is relatively inexpensive and easy to change. The instrument requires no consumables and continually runs diagnostics to ensure that if any component is deteriorating then the operator can carry out preventative maintenance.Procal Analytics have supplied many instruments to the paper and pulp industry throughout North America and in this instance the in-situ CEM analyser is monitoring: SO2 0 to 200ppm NO 0 to 500ppm NO2 0 to 250ppm CO2 0 to 15% Water Vapour 0 to 50%

Before the introduction of the PULSI 200LR, infrared multi-component in-situ analysers would have had trouble measuring this mixture of gas because of the very high water vapour.

Procal Analytics, through use of Gas Filter Correlation and Cross sense© correction, have enabled the reported data to be of a very high standard as required by the USA Environmental Protection Agency.

The monitored concentrations are displayed on Procal’s Analyser Control Unit, along with sample pressure and temperature. The system also includes a data logger to enable trends to be displayed and printed. Monitored concentrations are transmitted to the plant DCS.
