Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The combustion of petroleum coke releases large amounts of carbon dioxide and harmful chemicals into the atmosphere, and it contains elements like Vanadium that can damage processing equipment, necessitating methods for carbon capture and sequestration, as well as efficient disposal and utilization of petroleum coke.

Innovation Solution

Processing petroleum coke into a particulate form and creating a slurry that can be injected into underground areas, such as crude oil extraction wells or salt formations, while recovering elements like Vanadium before sequestration, thereby reducing atmospheric carbon dioxide and utilizing the coke for other applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If petroleum coke is combusted as a fuel source, then energy is produced, but large amounts of carbon dioxide and harmful chemicals are released into the atmosphere

Engineering Contradiction:

Improveenergy productionVSAvoidcarbon dioxide emissions

Core Design Contradiction:

Use of energy by moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful petroleum coke waste product into a beneficial carbon sequestration material by injecting it into underground formations, thereby preventing CO2 emissions while utilizing the carbon content for geological storage

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent extracts and removes petroleum coke from the combustion cycle entirely, separating the waste disposal function from energy production and directing it toward carbon capture and geological sequestration instead

Inventive Principle:

Principle #2Taking out (Extraction)

2Use of energy by moving object

If petroleum coke is combusted as a fuel source, then energy is produced, but harmful chemicals including sulfur are released into the atmosphere

Engineering Contradiction:

Improveenergy productionVSAvoidsulfur emissions

Core Design Contradiction:

Use of energy by moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent transforms the harmful sulfur-containing petroleum coke waste into a beneficial geological injection material, converting the pollution problem into a carbon sequestration opportunity that simultaneously removes sulfur from the environmental cycle

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Productivity

If petroleum coke containing Vanadium is processed, then energy utilization is improved, but processing equipment is damaged due to Vanadium reactions

Engineering Contradiction:

Improveenergy utilizationVSAvoidequipment integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent extracts petroleum coke from the energy production chain and redirects it to geological injection, removing the source of Vanadium contamination from processing equipment while still utilizing the material for carbon sequestration purposes

Inventive Principle:

Principle #2Taking out (Extraction)

4Ease of manufacture

If petroleum coke is disposed of through combustion, then waste management is simplified, but atmospheric pollution is increased

Engineering Contradiction:

Improvewaste disposal simplicityVSAvoidatmospheric pollution

Core Design Contradiction:

Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent converts the simple but harmful combustion disposal method into a more complex but beneficial geological injection process, transforming atmospheric pollution into carbon sequestration while maintaining waste management effectiveness

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
