A methanol spill disposal agent

Abstract

The invention discloses a methanol leakage treatment agent, which is composed of 40.0-90.0% anhydrous metal chloride, 5-30.0% solidification component, 0-20.0% adsorption component, 0-10.0% moisture-proof and flow-promoting component composition. The methanol leakage treatment agent of the present invention is a composite solid powder with anhydrous metal chloride as the main component. The chemical reaction between the metal chloride salt and methanol is used to convert the methanol molecule into a crystalline metal salt alcoholate, which is effective for leakage. The methanol disposal efficiency is high and the disposal is thorough; at the same time, the solidification component added can make the methanol solidify quickly and stop flowing, which has little impact on the environment of the leakage site.

Description

technical field [0001] The invention relates to the field of decontamination agents for hazardous chemicals, in particular to a methanol leakage treatment agent. Background technique [0002] Methanol is a widely used and important chemical basic raw material and high-quality fuel. As a volatile liquid, methanol often leaks during transportation and use. Due to its toxicity, volatility and flammability, once methanol leaks, it is easy to cause personnel poisoning, environmental pollution, and even major disasters such as explosion and fire, resulting in serious casualties and economic and property losses. Therefore, after methanol leaks, it must be disposed of quickly and effectively to minimize its harm. [0003] The common disposal methods for existing methanol leakage are mainly water spray flushing and adsorption with activated carbon and other powders. Since methanol is easily soluble in water, although the method of washing with water can reduce the concentration of ...

AI Technical Summary

Problems solved by technology

Since methanol is easily soluble in water, although the method of washing with water can reduce the concentration of methanol vapor, the degree of reduction is limited, and the methanol-water mixed solution obtained after washing still continues to flow, and methanol will continue to volatilize, which cannot reach The purpose of thorough disposal

Adsorbents such as activated carbon have low adsorption capacity for methanol and cannot quickly reduce the concentration of methanol. They only cover the surface of liquid methanol and cannot quickly solidify it. It is difficult to prevent its further flow and diffusion, and the adsorbed methanol will increase with temperature. Desorption due to changes in high-level external conditions, and volatilization again leads to secondary hazards
