Process Equipment and Plant Design In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement Results in higher shell side pressure drop Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Can accomodate less number of tubes for a given shell diameter Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Results in higher shell side pressure drop Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Can accomodate less number of tubes for a given shell diameter Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid ANSWER DOWNLOAD EXAMIANS APP

Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of the distillation column. The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up None of these If sufficient slot area is not provided, the gas may pass through the skirt clearance The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up None of these If sufficient slot area is not provided, the gas may pass through the skirt clearance ANSWER DOWNLOAD EXAMIANS APP
