American University Of The Middle East 2mxox+px This liquid phase reaction is assumed to be irreversible and is approximated by first-order kinetics with a rate constant of kr=0.133min1. The reaction is slightly endothermic. The simplified process is described in the following paragraphs: A liquid feed stream will enter the process at atmospheric pressure and a temperature of 77F at a rate of 1 million kg/ day. - A pump will be used to increase the pressure of the stream sufficiently to overcome the pressure drop due to friction in each of the components of the process (see the additional information given below). - Following the pump, the stream will pass through a shell-and-tube heat exchanger where the temperature will be increased to 500F using steam. - The hot pressurized stream will then be fed into a well-mixed isothermal reactor (maintained with a steam jacket around the reactor) where 70% of the mx will be reacted to form products. - The product stream from the reactor will be cooled as much as possible with cooling water in another exchanger before entering the separation system. - The separation system will yield three streams with the following mass fractions and that are all at the same temperature: FIGURE 1: MASS FRACTIONS OF OUTET STREAMSS Questions: 1.
