Solution Overview

Problem

Current methods for determining sediment and water content in hydrocarbon fluid samples, such as the API Manual of Petroleum Measurement Standards and other techniques, lack accuracy, especially in custody transfer measurements, necessitating the development of a more precise analytical method.

Innovation Solution

An integrated Karl Fischer-ultrasonic particle detector device (KF-UPD) that combines a weigh scale, a Karl Fischer titration device, and an ultrasonic particle detector to determine water and sediment content in hydrocarbon fluid samples, utilizing a titration vessel with specific apertures and probe seals for electrode and detector insertion, and a housing support unit to house these components, allowing for accurate measurement of water content via Karl Fischer titration and sediment content via ultrasonic detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If API centrifuge method or sight glass method is used, then both sediment and water volume analyses are provided in one test, but measurement accuracy is insufficient for custody transfer requirements

Engineering Contradiction:
Improvewater and sediment content accuracyVSAvoidintegration of multiple analytical devices
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines a Karl Fischer titration device for water content analysis and an ultrasonic particle detector for sediment content analysis into a single integrated system. The Karl Fischer device includes a titration vessel with electrodes and an ultrasonic detector positioned within the same vessel, allowing simultaneous or sequential measurement of both water and sediment content in crude oil samples, thereby achieving high measurement precision while maintaining operational simplicity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated device performs multiple functions within a single system: water content determination via Karl Fischer titration, sediment content determination via ultrasonic detection, and both measurements are conducted using the same titration vessel and sample handling system. This multi-functional approach eliminates the need for separate analytical devices while maintaining high accuracy for both parameters

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If Karl Fischer titration and ultrasonic detection are performed separately, then high measurement accuracy is achieved, but operational efficiency and ease of use are reduced

Engineering Contradiction:
Improveintegrated sample analysis procedureVSAvoidmultiple integrated components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the Karl Fischer titration system and ultrasonic particle detection system into a single integrated device sharing common components including the titration vessel, sample injection system, and control unit. The ultrasonic detector is positioned within the titration vessel to detect sediment particles during or after titration, allowing both measurements to be performed on the same sample without requiring separate operational procedures

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The ultrasonic particle detector is positioned and configured within the titration vessel before sample analysis begins. The detector is pre-calibrated and ready to measure sediment content as soon as the sample is introduced, eliminating the need for separate sediment analysis procedures and enabling immediate concurrent measurement with the Karl Fischer titration

Inventive Principle:
