Process Equipment and Plant Design Smaller sized packings are generally dumped to the packed columns, and the large ones of size greater than __________ mm are stacked individually, which provides better control over bed porosity and offers lower gas pressure drop. 25 150 75 50 25 150 75 50 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design High pressure fluid in a shell and tube heat exchanger should preferably be routed through the Shell side for smaller total pressure drop Shell side for large overall heat transfer co-efficient Tubes to avoid the expansion of high pressure shell construction Shell side, if the flow is counter-current and tube side if the flow is co-current Shell side for smaller total pressure drop Shell side for large overall heat transfer co-efficient Tubes to avoid the expansion of high pressure shell construction Shell side, if the flow is counter-current and tube side if the flow is co-current ANSWER DOWNLOAD EXAMIANS APP
