Petroleum Refinery Engineering Mercaptans are Low boiling sulphur compounds All of these Added in LPG cylinders to detect gas leakage by its smell Undesirable in petrol, as they reduce its octane number Low boiling sulphur compounds All of these Added in LPG cylinders to detect gas leakage by its smell Undesirable in petrol, as they reduce its octane number ANSWER DOWNLOAD EXAMIANS APP
Petroleum Refinery Engineering Choose the correct statement regarding thermal cracking. Greater depth of cracking gives lower octane number gasoline At low pressure, the yield of lighter hydrocarbons are more Increased residence time results in the decreased severity of cracking Moderate changes in operating temperature does not change the depth of cracking Greater depth of cracking gives lower octane number gasoline At low pressure, the yield of lighter hydrocarbons are more Increased residence time results in the decreased severity of cracking Moderate changes in operating temperature does not change the depth of cracking ANSWER DOWNLOAD EXAMIANS APP
