A dream technology, aiming to save energy and reduce criteria pollutants and polycyclic aromatic hydrocarbons (PAH) in flue gas pollutant emissions by using wastewater emulsified fuel oil (WWOEF), has been proved on industrial boiler at National Cheng Kung University (NCKU).

This technology is undergone patenting process, and a listed company in Taiwan is negotiating technology transfer with NCKU. It is estimated that in half a year this green energy technique can be applied in mass production.

This technology, developed by a green energy R & D team led by Prof. Wen-Jhy Lee, Department of Environmental Engineering at NCKU, is sponsored by National Science Council in Taiwan. After seven years of brewing and experimenting with this innovative idea, the result is published in the January 1st, 2008 issue of Environmental Science and Technology, a bimonthly academic journal published by the American Chemical Society.

The researchers used wastewater to make an emulsified oil (wastewater content 20% with 0.1% surfactant) to evaluate the extent of reductions in both criteria pollutants and polycyclic aromatic hydrocarbons compared with heavy oil fuel and water emulsified oil. The result showed that the wastewater emulsified fuel oil could significantly reduce particulate matter (PM), NOx, SO2, and CO as compared to heavy fuel oil and similar to those from water/oil emulsified fuel.

The reductions of total PAH flue gas emissions are 38 and 30% for wastewater and water-emulsified fuel, respectively, and 63 and 44% for total toxic equivalence (BaPeq), respectively.

In addition to reducing flue gas pollutant emissions, this technique also makes safe disposal of industrial wastewater and saves about 13% of energy in boiler operation, making WWOEF highly suitable for use in boilers. In monetary terms, if this technique can by applied worldwide, huge energy and wealth can be saved, which is indeed a rescue in time for the current state of this planet.

Its nice artical, and we can have it in our industrial area where this is useful. An expert with the help of government should start this project in industrial sector which available in every where. After successsful working this cost may be collect from the companies in that sector and money earened by selling of power may be distributed among the companies after deducting the running cost of the project, so the company in sector will get second earning source also the availability of energy will pull down the price of energy charges and push the production of industries.

Mr.Phani definitely a dream technology which will save energy and reduce pollution.and it would certainly be great for the whole world if it can be applied asap.
