Fixed charges initially Running cost of cooling water for condenser Vapour & liquid load both Running cost of steam for reboiler Fixed charges initially Running cost of cooling water for condenser Vapour & liquid load both Running cost of steam for reboiler ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In condenser, the cooling water is passed in the tube side in a pass arrangement, because It reduces heat transfer area More thinner tubes can be used Pressure drop is reduced It makes condenser compact It reduces heat transfer area More thinner tubes can be used Pressure drop is reduced It makes condenser compact ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, the clearance of the tube is generally Equal to the tube diameter More than the tube diameter Not less than one-fourth of the tube diameter or 3/16" More in case of triangular pitch as compared to the square pitch tube layout Equal to the tube diameter More than the tube diameter Not less than one-fourth of the tube diameter or 3/16" More in case of triangular pitch as compared to the square pitch tube layout 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 None of these 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 If sufficient slot area is not provided, the gas may pass through the skirt clearance None of these 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 ANSWER DOWNLOAD EXAMIANS APP
