About this document

Refinery Planning Optimization Techniques by xiaoqiangwang is a document available to read on EtoBox.

This thesis investigates the new nonlinear solution method called Extended Nonlinear Programming (XNLP) available in the refinery planning software PIMS. PIMS has traditionally used a method called Distributive Recursion (DR) that approximates nonlinear programs as linear programs. XNLP uses a nonlinear solver to directly solve the nonlinear programs. The thesis finds that for sample cases, XNLP does not produce significantly better objective values than DR but takes longer computation times, especially for
