Measurement of particulates, SO₂, NO_X, TRS and greenhouse gas emissions from the Pulp & Paper industry requires careful selection of instrumentation. Ecotech offers a complete monitoring solution tailored to this industry.

In the Kraft Process, commonly used in the pulp and paper industry to produce pulp, wood and chemicals are cooked in a digestor to remove the ligins and sugars, the waste from the digestor is know as “Black Liquor” and is typically burnt in the paper mills (Recovery Boilers) to generate electricity. The burning of the black liquor may produces high level of emissions.

Various byproducts containing hydrogen sulfide, methyl mercaptan, dimethyl sulfide, dimethyl disulfide, and other volatile sulfur commonly known as total reduced sulfur (TRS) are the cause of the malodorous air emissions which sometimes result from disturbance situations such as when the mill is shut down for maintenance.

SO2 and NOx emissions may also be generated by the recovery boilers, lime kiln and the plants power station. .

Ecotech is able to offer a complete monitoring solution for both emissions monitoring and ambient air quality monitoring fully integrated with our data evaluation and reporting software to meet the monitoring requirements of the pulp and paper industry. Ecotech has been involved in a wide variety of pulp & paper monitoring applications and is able to provide TRS analyzers as well as CO, SO2 and NOx instrumentation and systems.
