Process Equipment and Plant Design In the allocated cap area, bubble caps are generally arranged on equilateral triangular pitch. Number of caps fixed on a plate is with a Clearance of 25-75 mm Neither A nor B Cap pitch of 1.3-2 times the cap diameter Either A or B Clearance of 25-75 mm Neither A nor B Cap pitch of 1.3-2 times the cap diameter Either A or B ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement Can accomodate less number of tubes for a given shell diameter Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Results in higher shell side pressure drop Can accomodate less number of tubes for a given shell diameter Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Results in higher shell side pressure drop ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of the distillation column. If sufficient slot area is not provided, the gas may pass through the skirt clearance 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 The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles If sufficient slot area is not provided, the gas may pass through the skirt clearance 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 The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles ANSWER DOWNLOAD EXAMIANS APP
