How to Purchase the Right Industrial Air Compressors

Thursday, June 17th, 2010

For efficient work and production, companies make use of machines. Industrial air compressors are helpful machines used in large companies to increase their production. This machine has a lot of uses that is why before you purchase one, you need to know certain considerations. If you are a contractor, there are specific points that you must take into account before you will finally decide because you have think that work will be affected if you will not choose the right equipment.

There are a lot of trustworthy brands of this kind of machine with air compressor parts that are easy to find when you need some spare. A good number of manufacturers have marked credibility in this line of machines that you will not have any difficulty in choosing one. All you need to remember is to think of the quality and the cost of the machine if it is worth buying and if the service of the suppliers is quality guaranteed.

On the purchase of industrial air compressors, your first move is to specifically mention what you need so that you will lessen your choices on a few brands. This will make you choose the perfect one. You must specifically mention what type of power you will use for your machine. From the three sources, gas, natural gas and electric-powered, mention this to the store where you are buying.

In addition you have to mention the horsepower that you need it to have with the specific size of the tank. If you would use it for larger production then larger tank would then be required. As a contractor, it is also within your knowledge that you can mention the flow rate that you want your machine to have. Through this, you will get the specific tasks that you want for your industrial air compressors.

Air compressor spares is also recommended especially if you use the machine frequently. It is best to have parts readily available in case some repair is needed. Production can be affected if you will not solve the problem instantly. A portable air compressor is also better if you need to transfer from one construction site to another. However if you do not need to bring it to another area then there is no need for a portable one.

More about the Basics of Oxidizers for Air Pollution Control

Thursday, June 17th, 2010

Oxidizers are units that are used to process the noxious gas emissions from industrial plants, by oxidizing them with high temperatures, prior to their release into the atmosphere. These oxidizers are used in a number of industries and applications, including paper printing, petroleum refining, and other applications that produce various pollutants such as volatile organic compounds (VOC), Nitrogen oxides (Nox), and Carbon monoxide. All oxidizers can be categorized into two types based on their operation, thermal oxidizers and catalytic oxidizers.

Thermal oxidizers work on the principle of combustion and use the high temperatures produced by combustion to break down the hazardous gases into clean air for discharge. Based on their heat recovery system, oxidizers are essentially of two types – the recuperative thermal oxidizer and regenerative thermal oxidizer (RTO).

The recuperative-type uses an integrated conventional heat exchanger, known as the primary heat exchanger, as its heat recovery system and the recovered heat is used to preheat the incoming exhaust gas stream. In some cases, an additional heat exchanger, called the secondary exchanger, is also included in the flow after the primary exchanger to heat another fluid used in the process.

A specialized version of the RTO, known as the regenerative catalytic oxidizer or the RCO, uses ceramic media coated with precious-metal catalysts that help in the oxidation of the gas stream at comparably lower temperatures. This type of oxidizer, with its lowered operational temperatures, offers even greater reductions in operating costs.

Another type of thermal oxidizer used in some cases is the direct-fired thermal oxidizer, which lacks heat recovery system of any kind, making this oxidizer least capital-intensive. However, the lack of a heat recovery system makes this type of oxidizer expensive to operate. The catalytic oxidizer works by utilizing catalyst beds of precious-metal coated ceramic honeycombs or beads to enhance the rate of reaction of the exhaust gas stream.
