A fundamental unified approach from vectorial considerations is presented from which the usual rectangular and triangular difference point methods are derived as special cases. The approach is then extended to yield other difference point methods including some of higher order. Results are applicable to blending, distillation, extractio, foam fractionation, and other operations.
