Impact of feature reduction and operating temperature on gas identification
(
Asian Research Publishing Network
, 2015 , Article)
Tin-oxide based gas sensor requires an operating temperature typically in the range of 200 °C to 400 °C and its performance dependents on this temperature. In this paper a deep examination has been made to analyze the best ...
A comparative study of the treatment of ethylene plant spent caustic by neutralization and classical and advanced oxidation
(
Academic Press
, 2015 , Article)
The treatment of spent caustic produced from an ethylene plant was investigated. In the case of neutralization alone it was found that the maximum removal of sulfide was at pH values below 5.5. The higher percentage removal ...
