Northern Pulp Nova Scotia Corporation (NPNS) has completed the commissioning of the company’s new $35 million electrostatic precipitator.

September regulatory tests conducted at full firing rate show the recovery boiler precipitator particulate at 4 mg/Rm3. Testing carried out earlier in July by the company during the commissioning phase also revealed a result of 4 mg/Rm3. The industrial approval allows for a limit of 77 mg/Rm3. “We now have two test results with a single digit number for the precipitator, significantly reducing our environmental impact” states Bruce Chapman, General Manager with Northern Pulp. “The recovery boiler precipitator test results show the incredible performance and value of this major capital project.”

In 2011 new owner Paper Excellence determined that Northern Pulp’s precipitator was reaching the end of its useful life and began the lengthy replacement process which lead to construction completing in June 2015. An electrostatic precipitator (ESP) is a filtration device that removes fine particulate using an induced electrostatic charge.

Spring 2015 results of the power boiler were concerning and led the company to carry out proactive measures during the spring maintenance shutdown and throughout the summer. A power boiler emission limit Directive issued by Nova Scotia Environment (NSE) in June required Northern Pulp to provide a written report outlining planned actions. This report and inspection schedule has now been completed and submitted to NSE. September testing revealed power boiler level of 190 mg/Rm3 which exceeded the emission limit set at 150 mg/Rm3.

Upon receiving these latest results, Northern Pulp immediately contracted a boiler specialist to conduct a complete review of the entire power boiler system. The next series of recovery boiler and power boiler regulatory testing will be carried out in November. “We are fully committed to finding out and solving the cause of higher than anticipated numbers stemming from the power boiler” explains Chapman.
“Building on the success of the precipitator, we’re striving to be an environmentally sustainable business in the province. An important next step for Northern Pulp is reducing power boiler emissions.”
