4.8 In the processing train shown in Figure P14.8, two substances react in the presence of a catalyst, the reaction mixture is cooled, and the product is extracted in an absorber unit operation. Reactant A is the limiting reagent and both toxic and highly reactive. Reactant B is present at a stoichiometric excess of 1.5 . The catalyst can be poisoned by exposure to an excess of oxygen. The mass separating agent is toxic and must be removed from the final product to less than 2ppm, and although the catalyst may be regenerated, this is possible only if it is removed from by-product n HIGURE P14.8 (a) Write a balanced equation for the reaction. (b) Use a systematic approach to assess the IS and P2 issues associated with this process. (c) How can the process be made inherently safer
