Cairn Oil Chemical Engineer Interview Questions and Answers

The units in cpcl refer to specific heat capacity at constant pressure and specific heat capacity at constant volume.

• Units in cpcl are typically in J/(kg*K) or kJ/(kg*K).

• Specific heat capacity at constant pressure is denoted as cp.

• Specific heat capacity at constant volume is denoted as cv.

• The ratio of cp to cv is denoted as gamma (γ).

Diesel hydrotreating unit is a process used to remove impurities from diesel fuel through hydrogenation.

• Diesel hydrotreating unit uses hydrogen to remove sulfur, nitrogen, and other impurities from diesel fuel.

• The process involves passing the diesel fuel over a catalyst in the presence of hydrogen gas.

• The catalyst helps to break down the impurities into simpler, more stable compounds.

• The treated diesel fuel has improve...read more
