Coal Hydrogenation

Coal Hydrogenation

  • The coal hydrogenation process for making fuels has been investigated that its application on industrial process almost since 40 years ago.
  • Coal hydrogenation have been suggested that they are easily decomposed in the feed stock which consist sufficient sulfur, are not the true catalysts.

Cheap Cambodian sand reaches Chennai

Manufactured Sand has great Potential !
Look at what is happening..
suppliers of sand in Cambodia are able to supply one cubic foot of sand at around Rs. 12.
The price of sand has touched Rs. 65 per cubic foot in the city on account of various factors, including hoarding of sand by many suppliers
Government officials, including those from the Public Works Department, said that many projects including major infrastructure projects in the city are being hit by the scarcity of sand.
According to officials, sand price accounts for around 15 per cent of the project cost at present. Even though the State environment impact assessment authority had recently accorded clearance for a few sand quarries, the scarcity of sand in the city is likely to continue this monsoon.
The Mekong River sand from the river has already been exported to countries such as Singapore. The river runs through countries including China, Myanmar, Laos, Cambodia and Vietnam
