TRIZ方法在降低炼厂VOCs系统氮气耗量上的应用

TRIZ Methods for Reducing Nitrogen Consumption inVOCs Systems in Refineries

炼厂储罐VOCs排放指标控制一般通过炼厂储罐VOCs系统的油气冷凝回收及尾气焚烧措施实现。现行处理方法因冷凝回收功能的不足,需要对尾气进行焚烧处理,但焚烧处理即会造成尾气中氮气的无效利用,造成氮气的损失。针对在炼厂储罐VOCs处理系统中的氮气耗量高的问题,探索利用创新方法TRIZ理论中的功能分析、因果分析、冲突分析、理想解分析确定系统中关键问题点及根本原因,运用冲突解决工具、物质-场标准解决工具、效应、裁剪工具等寻求问题的解决方案,得到问题的最终方案。

The control of VOCs emissions from storage tanks in refineries is generally achieved through measures such as oil and gas condensation recovery and tail gas incineration in VOCs systems.Current treatment methods,due to insufficient condensation recovery functionality,require incineration treatment of tail gas.However,incineration treatment results in the ineffective utilization of nitrogen in the tail gas,leading to nitrogen loss.To address the issue of high nitrogen consumption in VOCs treatment systems in storage tanks in refineries,the study explores the use of innovative methods such as functional analysis,causal analysis,conflict analysis,and ideal solution analysis from the TRIZ theory to identify key problem areas and root causes in the system.Conflict resolution tools,substance-field standard solution tools,effects,trimming tools,and other TRIZ tools are used to seek solutions to the problem and develop a final solution.
