pH-Modified WS-ODSO Compositions for DSO Waste Valorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an efficient and economical process to treat large volumes of disulfide oil (DSO) by-products and their derivatives to modify their properties for environmentally acceptable disposal and enhance their value, as they are often disposed of due to their foul smell and higher sulfur content, which poses handling and regulatory challenges.
Innovation Solution
A pH-modified water-soluble oxidized disulfide oil (WS-ODSO) composition is created by mixing WS-ODSO compounds with an alkaline agent, adjusting the pH to a higher level, which can be neutralized, deacidified, or basified, reducing acidity or increasing basicity, and is used as a component in synthesis processes, including zeolitic materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If DSO compounds are disposed of due to foul smell and higher sulfur content, then environmental compliance is improved, but resource utilization is worsened
Solution Approach 1:
The patent converts the harmful acidic properties of DSO compounds into beneficial characteristics by neutralizing the acid to create a pH-modified composition. This transformed product can be used as a reagent in synthesis processes, converting what was previously considered waste into a valuable chemical resource.
Solution Approach 2:
The patent fundamentally changes the pH parameter of the DSO compounds from acidic to neutral or basic conditions through neutralization with alkaline agents. This parameter modification transforms the chemical properties, enabling the modified composition to serve as a useful reagent in various synthesis applications.
2Loss of substance
If large volumes of DSO by-products are treated, then environmental impact is reduced, but processing complexity is worsened
Solution Approach 1:
The patent employs a straightforward neutralization process where alkaline agents are added to DSO compounds to adjust pH. This simple self-service approach transforms the waste material without requiring complex processing equipment or multi-step operations, making it feasible to handle large volumes efficiently.
3Loss of substance
If DSO compounds are utilized as reagents in synthesis processes, then resource value is improved, but pH control requirements are worsened
Solution Approach 1:
The patent performs pH modification as a preliminary step before using the DSO derivatives in synthesis processes. By pre-neutralizing the acid and adjusting the pH to appropriate levels beforehand, the subsequent synthesis processes can proceed with standard pH control requirements, avoiding the need for complex real-time pH management.
