Innovative Solutions Enable Smooth Operation in Paper and Pulp Industry

ITC Paperboards and Specialty Papers Division (ITC-PSPD), the largest manufacturer of Packaging and Graphic Boards in South Asia, faced the issue of high downtime in their control and DCS rooms. Seeking a solution, they reached out to Bry-Air, who recommended installing granular media based thin vertical (TV) systems in their critical rooms. Installation of Thin Vertical (TV) systems successfully increased the uptime of the ITC-PSPD critical equipment.

About ITC Limited

ITC-PSPD, Bhadrachalam plant is the single largest plant in India with a production capacity of 8,00,000 TPA Virgin Paper & Paperboards. ITC-PSPD is ISO 9001:2015 – Quality Management System Standard and ISO 14001:2015 – Environmental Management System Standard certified.

Problem

High downtime due to failure of electrical and electronic equipment. This problem was predominantly caused by corrosive gases such as SOx, NOx, CO2, H2S, Cl2, etc.. These gases are generated in various processes involved in pulp mills, soda recovery boilers, ETP plants etc.

Solution

To remove the corrosive gases in the critical equipment rooms, ITC-PSPD collaborated with Bry-Air (Asia) Pvt Ltd., experts in the air treatment solutions. Our Airgineers® closely worked and measured corrosion levels in an enclosed environment of critical rooms using our Corrosion Classification Coupon (CCC).

We provided effective strategies to combat the poor gaseous environment causing corrosion and ensure the smooth and reliable operation of the critical rooms.

We suggested installing the Bry-Air EcoScrub Gas Phase Filtration (GPF) System – BPU Thin Vertical Air Purification System considering the areas of the corrosion-sensitive critical rooms.
