Process Equipment and Plant Design Steam economy is defined as the amount of evaporation per unit amount of steam used, while the capacity is the total evaporation obtained per hour. Use of multiple effect in evaporation Both B & C Increases economy Does not affect the capacity Increases capacity Both B & C Increases economy Does not affect the capacity Increases capacity ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Normally, the ratio of the total riser area to the tower cross sectional area (for bubble cap towers of diameter more than 3 ft) is around 0.35-0.75 0.1-0.2 0.4-0.6 0.55-0.85 0.35-0.75 0.1-0.2 0.4-0.6 0.55-0.85 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Pick out the wrong statement about the design of seive plate column and the bubble cap column. Weir height for a bubble cap plate column is the same as that for a seive plate column Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns Weir length for a bubble cap plate is the same as that for the seive plate Weir height for a bubble cap plate column is the same as that for a seive plate column Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns Weir length for a bubble cap plate is the same as that for the seive plate ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger for a given heat transfer surface area, smaller diameter tubes are favoured as compared to larger diameter ones ; because the smaller diameter tubes Are easier to clean None of these Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are less prone to fouling Are easier to clean None of these Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are less prone to fouling ANSWER DOWNLOAD EXAMIANS APP
