TUBE/SHELL HEAT EXCHANGER
TUBE/SHELL HEAT EXCHANGER
(OP)
I have a tube/shell exchanger with steam been the hot liquid and Fuel oil the cold liquid.The steam is in the tubeside.It has been designed to work with a maximum pressure of 13bars. I would like to know if any small modification can be done to the heat exchanger such that it can support steam pressure of up to 17bars.

Otherwise if you try to use 17 barg you will have to re-rate your exchanger and make an official test

RE: TUBE/SHELL HEAT EXCHANGER
what do you mean by re-rating a heat exchanger. Is it something that somebody in a technical department in a refinery can do or does it need a specialist company to do.Thanks

The Maintenance Department inside your refinery should be able to perform a calculation in order to rate your pressure vessel(s) for higher operating pressures. Significant factors include operating temperature, exchanger tube thickness, history (time) of exploatation etc.
I had an opportunity to re-rate naphtha stabilizer column from MAX 7.2barG up to 10barG, because of insufficient condenser capacity.
