Liquid fuels such as gasoline and kerosene are widely used in transport bureau and because of their flammability always there is a risk of pool fires during their storage and transportation. Also there is very flammable materials like peroxides which are widely used in chemical and petro chemical industries. The potential risk of accidental release of these materials and the hazard of pool fires is always concerned by relative companies and HSE engineers. Thus to minimize the destructive effects of this events one should have a good knowledge of the characteristics of the pool fire of this...

In present study, Light weight Expanded Clay Aggregate (LECA) coated with iron (Fe) oxide has been explored as a green and low cost sorbent to remove Ni (II) from polluted water. Iron Oxide Coated LECA (IOCL) as a new sorbent was examined for its efficiency as Ni (II) sorbent by change the operational parameters, such as contact time, initial pH of the solutions, sorbent dosages and initial Ni (II) concentration in batch systems. Also the adsorption characteristics of Natural LECA (NL) and IOCL were examined trough X-ray Fluorescence Spectroscopy (XRF), Scanning Electron Microscopy (SEM),...

Ethylene is widely used in chemical industry, and its worldwide production(over 109 million tonnes in 2006) exceeds that of any other organic compound. Commercially ethylene is obtained by(1)thermal cracking of hydrocarbons such as ethane, propane, butane, naphtha, kerosene, gasoil, crude oil, etc, (2) auto thermic cracking (partial oxidation) of the above hydrocarbons, (3)recovery from refinery off-gas, (4) recovery from coke-oven gas, and(5) catalytic dehydration of ethyl alcohol or ethyl ether. The thermal cracking process is the most interesting process to produce ethylene commercially...
