US 2003/0171848 A1 · Apparatus for process line testing

Abstract

The invention relates to an apparatus and method for testing the properties of chemicals in a reaction flow stream. In the method, chemicals from the reaction flow stream are directed to the apparatus for testing the physical properties of the chemicals, which is an indication of the state of the chemical reaction. Data measured by the apparatus is stored in a computer, and the computer may be used to analyze the data and to control the reaction parameters based on the analysis of the data. The apparatus used for the analysis comprises a rheometer having an actuated shaft and a concentric container, wherein the shear properties of the material sampled in the apparatus are measured when the actuator shaft is oscillated within the container. Various unique configurations of the apparatus are described.

Dependent claims

A method for analyzing the chemical or physical properties of a fluid in a reaction flow stream comprising the steps of

(a) providing a tap line in a chemical process line for tapping off a sample of fluid from a reaction flow stream
(b) directing said sample of fluid to an analyzer for testing the physical and/or chemical properties of said fluid
(c) collecting data on the physical and/or chemical properties of a fluid from said analyzer and storing said data in a computer, and
(d) using said computer to control the parameters of the chemical reaction process
in said reaction flow stream, wherein the analyzer data is used by the computer to determine current reaction conditions and to control the reaction parameters to maintain or achieve preselected reaction conditions.
