Process Optimization

Use online analyzer technology to optimize CCR unit operations

First, we must consider the background: Why is optimization of refinery process units so common and so necessary, and what analytical tools exist to help?

First, we must consider the background: Why is optimization of refinery process units so common and so necessary, and what analytical tools exist to help? The key problem in refining is that, although crude oil refining is a continuous and high-volume process with very significant raw material and energy costs, it is not steady-state. Crude oil feedstocks vary continuously in quality, availability and cost. At the same time, refinery products and their markets are very dynamic in terms of demand, specifications and pricing. This scenario leads to the use of relatively complex linear programming (LP) models to manage these changes. Underneath these models, individual process unit advanced pro
