Lecture 33 Recycle with Purge in Reactive Systems

This video explains a problem on recycle with purge in reactive systems. This is taken from the text book by Himmelblau. Extent of reaction is used to solve the problem. Carbon monoxide and Hydrogen react to form methanol in a reactor in which conversion per pass is 18%. Fresh feed contains 67.3 mol% Hydrogen, 32.5 mol% Carbon monoxide and remaining is methane as inerts. The concentration of inerts in the purge stream is 3.2 mol%. For a basis of 100 mol of fresh feed, molar flow rates of purge stream, product stream and recycle stream have been calculated.
