Response surface for the Q (MW) variable as a function of the feed composition. Each subfigure represents a combination of the type of mixture with the thermal conditions of the feed. The rows represent the mixture (M 1 , M 2 , M 3 ) and the columns represent the feed thermal conditions: saturated vapour (subfigures a, d and g), vapour-liquid mixture with q = 0.5 (subfigures b, e and h) and saturated liquid (subfigures c, f and i).
