EcoScrub Protects Server from Corrosion at ABC Paper

ABC Paper, a division of Amrit Banaspati Co. Ltd. Sailakhurd, Punjab, (108 km from Chandigarh) is one of the largest wood-free paper plant. They use only agro-wastes like wheat, rice-straw, kana grass etc. to manufacture fine quality printing & writing paper. ABC Paper is the leader in the cream-wove paper in agro-based segment.

The Problem :

The server in the administrative block was regularly breaking down causing productive losses.

The Cause :

Cocktail of corrosive gases in the Environment !

The Source :

The open Tank: where the waste liquids from process was being mixed with urea to neutralize the toxic waste. This, however, resulted in Ammonia formation harmful to electronic equipment like servers.

The process itself: The process of pulping, pressing, bleaching uses a variety of corrosive chemicals like chlorine, etc.

Corrosive by products (gases) like H2S, SO2, etc. are generated by the various processes.

As a result the server failed every 20-27 days !!

Bry-Air Airgineers helped ABC to solve the problem with EcoScrub inside.

The Airgineers from Bry-Air did a thorough environment check at ABC Paper with asophisticated ECM (Environment Control Monitor) in the server room.

(ECM is a device used to determine the overallcorrosive environment before control measures are implemented and which show results instantly as per the ISA standard S71.04-1985, which defines an environment as G1,G2, G3, & Gx based on corrosion severity level).

Once the corrosion levelwas determined, the Airgineers suggested installation of a Bry-Air EcoScrub Gas Phase Filtration System (dry scrubber deep bed) BPU-Dmodel outside the server room for pressurization.

The server room is now pressurized with dust and corrosive gas free air. Thus, infiltration of corrosive gases like H2S, CL2, NH3, SO2, NOX, etc. and dust is contained.

This ensures that the environment is maintained as per ISA71.04 but also removes odour from the server room.
The monitoring program ensures G1 level all the times as per Instrument Society of America standard 71.04.

The deep bed BPU-D model units areself-contained units incorporating all particulate filters, chemical filters and supply fan. The unitsucks the outside air where dust isremoved with the help of particulate filters and variousother gases areremoved with the help of dry BrySorb special chemical filters.
