As an important procedure of the manufacturing process in refinery, oil blending could be abstracted as a complex non-linear optimization problem (NLP) with many constraints.

(2) A simulated manufacturing execution system (MES) for oil blending was developed by combining an optimization program with the oil storage district simulator stated above.

Recipe Optimizing and Short-Term Scheduling for Oil Blending;

Considering the fuzzy constraints for oil blending such as market demand,blending ability,capability of pot and so on,and a method of fuzzy programming with multi-object to solve these problems is presented and a model of fuzzy programming with multi-object is established.

Oil blending is an important production working procedure in a refinery and the great benefit of refineries can be achieved from the optimization of oil blending.

Investigation on the Equipoise of Fatty Acids in Chinese Diet and Studies on Blending Oil of Fatty Acids Balance;

The viscosity,combustion heat,sulfur content,carbon residue,ash,flash point,moisture and cetane value of biodiesel and its blending oils with diesel were determined.

The paper is to research the influence regulation on cottonseed oil ratio and blending oil heat value.

The calculating methods of octane number and Reid vapour pressure for gasoline blending are presented.

This article introduces constitution and principle ofquality control system which chief composition areASTM-CFR engine model Octane number analyzerand μ XL distributed control system for the free-leadgasoline blending installation, and summarizes thegood effect after the gasoline blending optimal controlscheme have been implemented, and indicates thedirection to make further efforts in the future.

According to the situation of the online optimization gasoline blending system in QRC,it is found that the system can adjust each index in the optimal range when the character of petrol changes and the variable is in controllable scope in each step.
