DESIGN OF BOILER STACK
ABSTRACT
Chimney, which form the last component of a system using a flue gas such as feoiler, IC engines, play a vital role in maintaining efficiency, draft, etc, of a system and also in minimizing the atmospheric pollution.
The boiler plant of HOCL had used LSHS (low Sulphur heavy stock) as a fuel. Recently they changed the fuel to LSFO (low Sulphur furnace oil). As a combined effect of increased corrosion rate and natural calamities the stack had undergone failure. As per the Kerala State Polluti ....etc

Photocatalysis is an advanced oxidation process and receiving widespread attention in recent times for completely mineralizing organic contaminants in water and air. As a first part of our study, the parameters (dissolved oxygen, catalyst concentration, and light intensity) influencing intrinsic kinetics of phenol degradation is investigated using immersion-well batch reactor with 6 and 125 W UV-A lamps. At high light intensity, dissolved oxygen concentration in the slurry decides the optimum catalyst loading. At low light intensity comparable ....etc

Bio-oxidation treatment was a final step in cleaning excess process
water or waste ammonia liquor that originated from coke oven gas
produced during the coking process
In this process, phenol and thiocyanate were eaten (oxidized to carbon
dioxide and water) by bacteria at a bio-oxidation plant. The treated
water was then sent to the City of Bethlehem's municipal sewage
treatment plant where the remaining ammonia was eaten by a yet another
strain of bacteria and made safe to discharge into the Lehigh River
The bio-oxidation plant op ....etc

Introduction:
Household items made of various kinds of plastic.
Plastic is the general common term for a wide range of synthetic or semisynthetic organic amorphous solid materials used in the manufacture of industrial products. Plastics are typically polymers of high molecular mass, and may contain other substances to improve performance and/or reduce costs. Monomers of Plastic are either natural or synthetic organic compounds.
The word is derived from the Greek past (plastikos) meaning fit for molding, and past ....etc
