Capital and operating cost can be saved by using multi-tubular catalytic reactor in place of conventional fixed bed catalytic reactor

If we use multitubular reactor in place of conventional multibed reactor in manufacturing of Ethylbenzene, we do not need to use heat exchangers (reaction is extremely exothermic) So, here we can save capital cost and operating cost of around three to four heat exchangers. Hence, we can ultimately save energy and money. Here, we used HTRI programme for heat exchanger. We had to carry out manual calculations for design of heat exchangers to find out capital cost. We found out energy saving also. So, here attempt is made to give a thought of changing process or equipment during we decide our project and we can save energy and money.
