Question
Consider the VAM process described in Example 2-1. A new reaction pathway has been developed and will be used for the production of VAM. This new reaction does not involve acetic acid. The rest of the process remains virtually unchanged and the AA losses with the product are 100 kg/h. What are the targets for minimum fresh usage and discharge/losses of AA?
