Regulatory testing carried out on Northern Pulp’s power boiler indicates a marked improvement compared with tests carried out earlier this year.
The most recent tests for the kraft mill located in Abercrombie, N.S., show a result of 111 mg/Rm3. September testing revealed a level of 190 mg/Rm3 which exceeded the emission limit set at 150 mg/Rm3. Upon learning the September results, Northern Pulp immediately contracted a boiler specialist to review the mill’s entire boiler system. The company was also directed to review the system by the provincial department of the environment.
The review, which began in October, led to the implementation of several operational improvement recommendations. Initial findings and recommendations regarding air distribution have already been executed.
“We committed to better understanding the power boiler and reasoning for the varying test results,” states Bruce Chapman, general manager with Northern Pulp. “We have a plan in place which will see us continue this positive trend of improving our environmental performance.”
Recent emission testing reveals that the new $35-million electrostatic precipitator in operation at the pulp mill continues to significantly reduce the mill’s environmental footprint.
Mid-November regulatory test results conducted at full production firing rate show the recovery boiler precipitator particulate at 2 mg/Rm3. Testing conducted in July and September by the company during the commissioning phase revealed a result of 4 mg/Rm3. The industrial approval allows for a limit of 77 mg/Rm3.
