Project: Heavy Duty Presses (HDP) design, installation, and commissioning

• 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

Project Achievements:

• 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.

Project: Coolers and packed carbon bed design, installation, and commissioning

• Performed analysis to find out the loss of Mercury and heat through the process.
• Mass and energy balance of each individual cells and decomposer
• Calculated total heat duty, and surface area required for the heat exchanger.
• Estimated the amount of mercury recovered from cooling process and carbon bed.

Project Achievements:

• Developed a design of cooler which get down the Hydrogen gas temperature from 100°C to 20°C.
• Saved 10% operational cost by reducing mercury losses from 1.90 to 1.05 gm Hg/ton of chlorine, and heat losses by 5%
