FILTRATION SOLUTIONS FOR
A WIDE RANGE OF INDUSTRIES
Providing advanced products and high technical competency is at the heart of everything we do. Our expertise spans a wide range of industries and our aim is to help reduce air pollutants to the lowest possible levels at a reasonable cost to these industries.
FLKCAT filters are ideal for businesses within the following industries:
- Waste to energy
- Waste incineration
- Diesel fired power plants
- Carbon black
Many industries employ high temperature processes to produce materials and services in everyday use such as glass, cement, chemicals, metals and power generation. Unwanted by-products from these processes can cause pollution of the environment by depositing waste materials into water or air. Nitrogen oxides (NOx) are formed when air is used in high temperature combustion, melting or calcining processes. Dust can also be released during these processes and acid gases and volatile organic compounds can be formed. However air pollution control techniques exist to remove these pollutants at source to ensure that the impact on the environment is minimised.
Some of these techniques are old technologies often called “end of pipe” , which are stuck onto the end of the production line to clean up emissions just before emission to atmosphere. New techniques now exist that supersede these “end of pipe” processes. The new techniques give the option to place the filtration stage at other points in the process not only to improve emission standards but also to recover energy. In fact the filter can be placed in the ideal position for the benefit of the process. The new techniques use the naturally high gas temperatures to treat multi-pollutants in a single step and still offer the opportunity to recover good quality heat energy.
Recovery of heat energy is now the focus of many energy intensive industries such as glass and cement and fibrous ceramic filters offer a real opportunity to maximise the benefits of heat recovery. The filters reduce the particle loading of the gas to such low levels that heat exchange or boiler tubes are not fouled by fugitive dust and therefore high quality heat energy can be recovered.
Processes such as waste to energy or biomass energy plants can utilise the high temperature filtration properties of fibrous ceramic filters to give syn gas and combustion gases or fuel that is completely free of fine dust. Fine dust that would otherwise foul sensitive combustion equipment heat recovery systems and boilers. Gasification of biomass is an ideal application for fibrous ceramic filters.
The glass and cement industries produce hot gases with dust SOx and NOx pollutants. Fibrous ceramic filters with embedded catalyst and the use of sorbents can reduce the emissions of these pollutants to almost immeasurable levels and the cleaned gases can then be used for energy recovery.
Ceramic filters are such efficient filter products that even micro fine particles such as those generated in carbon black production and from diesel fired power plants are captured by the super efficient HEPA rated filter medium. Carbon black is notoriously difficult to filter but ceramic filters not only easily capture these fine and sticky particles but also deliver a stable pressure drop and a long life filter
Diesel fuelled engines too can generate fine and sticky soot particles but again they are easily captured at the surface of the filter giving reliability and a steady performance. There are also options to control and reduce emissions of SOx and NOx by adding appropriate chemicals and sorbents.
