Parts Per Million Detection in Semiconductor

Containers of hazardous gases, both flammable and toxic, are often isolated from the surrounding environment by safety enclosures (gas cabinets). Some process tools have a gas control enclosure section that serves the same purpose as a gas cabinet. It is important to monitor these enclosures for leaking gas to save product as well as prevent a toxic condition. The cabinets and enclosures are ventilated to prevent the buildup of any leaking gas.

Hazardous Monitoring in Semiconductor Facilities

Reliable gas detection and monitoring systems are an essential element of the semiconductor plant’s safety system. It requires gas detection systems that can accommodate a variety of combustible and toxic gas applications with both single and multi-sensor network solutions. A variety of systems are available for different monitoring applications. Using the correct system will result in managing gas hazards in the most effective and efficient way.

Application Spotlight: Semiconductor

Semiconductor manufacturing facilities employ a number of hazardous gases in their production processes.

Pollution Control in Real Life

For the past couple weeks we shined the spotlight on the Pollution Control Industry; we've looked at the threee ways to reduce emissions (Oxidizers, Incineration & Solvent Recovery). This week let's discuss HOW, by looking at real life applications:

Happy Thanksgiving

We ought to make the moments notes

Of happy, glad Thanksgiving;

The hours and days a silent phrase

Of music we are living.

And so the theme should swell and grow

As weeks and months pass o’er us,

And rise sublime at this good time,

A grand Thanksgiving chorus.

~ Ella Wheeler Wilcox

Pollution Control: Solvent Recovery

Solvent recovery systems recover and re-use solvents from manufacturing processes. Solvent laden air from the processes is passed through an activated carbon bed. When the carbon bed is nearly saturated with solvent, a steam-down cycle occurs to condense out the solvent for re-use. The carbon is then regenerated for another collection phase. Two carbon beds are used so that one bed can process the solvent-laden air while the other one is regenerating.

Pollution Control: Incineration/Flare Stacks

It is becoming increasingly important to reduce emissions while saving energy when using a pollution control device such as a flare stack. Proper flare stack design is essential to handle their multiple waste streams for maximum performance with minimum emissions. Since destruction efficiency and emissions (both visible and invisible) are some of the most important criteria to consider when designing a flare, when the design is done correctly, dramatic money savings will also be realized.

Pollution Control: Incineration/Oxidizers

A flame ionization detector at the outlet of the oxidizer ensures that it does not exceed emission levels. In addition, by using two flame ionization detectors, one on the inlet and one on the outlet, hydrocarbons can be measured and compared before and after processing, indicating efficiency.

Application Spotlight: Pollution Control

Air pollution control devices are a series of devices that work to prevent a variety of different pollutants, both gaseous and solid, from entering the atmosphere primarily out of industrial smokestacks. These control devices can be separated into two broad categories - devices that control the amount of particulate matter escaping into the environment and devices that control acidic gas emissions.
