Solution Overview

Problem

Current methods for detecting sugar in boiler condensate and feedwater are laborious, require high maintenance, and lack reliability, leading to inefficiencies and contamination issues in industrial processes, particularly in fermentation and steam-generating systems.

Innovation Solution

A method involving the measurement of oxidation-reduction potential (ORP) at operating temperatures and pressures using CSM devices, with a controller to assess and correlate ORP levels to sugar presence, triggering alarms or corrective actions to maintain optimal conditions, and optionally injecting reductants or pH-controlling chemicals to manage contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional colorimetric methods with grab samples are used, then measurement can be performed, but the process is laborious and requires manual intervention

Engineering Contradiction:

Improvemeasurement efficiencyVSAvoidmanual intervention requirement

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent replaces manual colorimetric analysis with an automated electrochemical sensing system. The ORP sensor continuously measures oxidation-reduction potential in the boiler water, eliminating the need for manual grab sampling and colorimetric testing. This substitution of mechanical/manual processes with automated electrochemical measurement directly resolves the contradiction between measurement capability and operational complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements continuous online monitoring of oxidation-reduction potential throughout the boiler water system. Instead of periodic grab samples, the system provides continuous real-time data, ensuring uninterrupted detection of sugar contamination. This continuous action eliminates manual intervention cycles and maintains constant surveillance of water quality parameters.

Inventive Principle:

Principle #20Continuity of useful action

2Reliability

If online measurement systems are implemented, then continuous monitoring is achieved, but maintenance requirements increase and reliability decreases

Engineering Contradiction:

Improvedetection reliabilityVSAvoidmaintenance requirement

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The patent employs a simple, robust ORP sensor that can be easily replaced if needed, rather than investing in complex online measurement systems that require high maintenance. The sensor is designed to be inexpensive and straightforward to install and replace, reducing the burden of maintenance while maintaining reliable detection capability. This approach prioritizes simplicity and reliability over high-maintenance sophisticated systems.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Loss of time

If sugar contamination is detected early, then corrective action can be taken, but conventional methods have lag time and miss early contamination

Engineering Contradiction:

Core Design Contradiction:

Loss of timeVSMeasurement precision

Solution Approach 1:

The patent continuously monitors oxidation-reduction potential in advance, detecting sugar contamination before it reaches problematic levels. The system provides early warning signals that allow preventive corrective action to be taken, preventing contamination from developing into serious problems. This preliminary detection capability eliminates lag time by continuously surveillance rather than reactive sampling.

AI summary

This invention provides a method for detecting sugars in boiler condensate and/or boiler feedwater in industrial processes. The method includes measuring an oxidation-reduction potential at one or more locations in the process with one or more devices capable of measuring oxidation-reduction potential at operating temperature and pressure and correlating that measurement to an amount of sugar in the system. If the measured oxidation-reduction potential is not within an optimum range, action is taken.
