Chetwynd Mechanical Pulp Mill, Paper Excellence Group, Chetwynd, BC, Canada

• Monitored day to day unit production, key processing indicators, and process unit performance.
• Provided continuous supports to operations team to achieve process optimization.
• Ensured air and water (ground and potable) quality to meet BC Ministry of Environment Permit limits.
• Analysed process data, and trend analysis to increase productivity.

• Performed to find out the loss of pulp fiber through the process.
• Worked on mass balance of each individual Twin wire Press, and Heavy-Duty Press 
• Calculated total dryer steam savings, and product tonnage increased.
• Estimated the amount of process water savings, and total operational cost savings/yr. for our mill.
• performed hazop studies several times to address process and operational safety, & environmental risks

• Developed a novel design of HDP which increase pulp consistency 2% (from 48-50%) in HDP discharge which save 53 MT process water/day,94 MT Steam/day, and shipping cost CAD 4,211/day (due to less water in product) 
• Total savings for Chetwynd Mechanical Pulp Mill about 1.5 $MM/yr. 

Chemical and Biological Engineering, University of Saskatchewan
