Contaminated Air?

Contaminated air generated from today's industry is laden with undesirable gaseous compounds such as hydrogen sulphide, sulphur dioxide, mercaptans, chlorine, ammonia, nitrogen oxides, hydrocarbons etc. which cause corrosion of process computers and delicate electronic equipment.

Effects

Leads to complete component destruction e.g. breakage of sensitive wires & circuits, failure of delicate chips, transistors, ICs etc.

Causes Sporadic electrical hiccups, called intermittent which frequently cause minor computing or controlling errors may contribute to prolonged disruption or even complete shutdown of the plant.

Result

• production stoppages
• increased production cost.
• higher maintenance budgets
• lower productivity and sometimes, false signals / alarms.

Why do we need to protect our control rooms?

Studies have shown that atmospheres which produce corrosion rates greater than 0.1 microns per year cause unacceptable number of corrosion - related failures of micro-circuitry.

Corrosion Rate per year vs. Equipment Failure (in micro-circuitry)
< 0.1 micron               No failures found
> 0.1 micron               Intermittent failures in 1-2 years
> 0.4 micron               Inoperative in 2-4 years
> 0.6 micron               Intermittent failures in 0.5 - 1 year
> 2.0 micron               Inoperative in 0.25 - 0.5 years

For electronic equipment, corrosion rate has to be below 0.1 micron per year.
For electrical equipment, the same can be as high as 0.5 micron per year.
(1 micron = 0.001 mm)

The Solution.

Bry-Air, an ISO 9001 and 14001 company, a pioneer in the field of dehumidification equipment offers 'state-of-the-art' Air and Gas Purification Systems for various application areas. The ultimate solution to corrosion lies in gaseous filtration which involves passing the contaminant laden air stream through a bed of dry media placed in a properly designed housing. The principle of air purification is simple : the contaminated air passes through pre-filters which retain dust and particles, and then the required chemical media stages (combination of activated carbon and activated alumina impregnated with proprietary chemicals) which chemically destroy any remaining gaseous contaminants. It is a simple, yet cost effective solution to a problem that can be very costly from a production standpoint.

Besides a complete line of gaseous filtration products ranging from filter media to adsorber housings, Bry-Air offers the latest technology in gaseous adsorption such as Ammonia-Gas Phase Activated Carbon process which greatly increases the adsorption capacities of activated carbon.

Standard sizes of Bry-Air ECOSCRUB air and gas purification equipment range from 72 m3/hr (40 cfm) to 86,400 m3/hr (51,000 cfm) offered in both pressurization as well as re-circulation modes. All Bry-Air systems are designed to operate and maintain corrosive gas levels at 1 ppb or less.
