METHOD AND PROCEDURE FOR ON-LINE MEASUREMENT OF FLUID PROPERTIES FOR CONTROL AND OPTIMIZATION

摘要

A METHOD AND PROCEDURE FOR ON-LINE MEASUREMENT OF FLUID PROPERTIES FOR CONTROL AND OPTIMIZATION A method of on-line measurement of fluid properties is disclosed. The temperature range and pressure range to which the fluid might be exposed is divided into predetermined subregions. The actual temperature and pressure of the fluid determines the subregion which is utilized. The subregion that is utilized provides temperature and correction factors which are combined with a reference value of the fluid property being measured to determine the actual value of the fluid property.
