Fabric filtration is the surest means of removing fine particles. EPRI has devised the 'Compact Hybrid Particulate Collector' (COHPAC). This design simply places a baghouse after an ESP. The ESP removes much of the particulates, easing the load on the baghouse, hence reducing maintenance. The bag-house reduces pollution due to rapping loss, and is insensitive to changes in fuel.

EPRI has also developed an 'EPRICON' process which can replace conventional chemical conditioning of fly ash from low sulfur coals. In this process, a portion of the gas stream is diverted to a vanadium oxide-based catalytic unit, which efficiently converts SO2 to SO3. Recombination of the treated stream with the bulk results in the necessary conditioning of the fly ash.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
