High molecular cleaning agent for pollutant and preparation process thereof

Abstract

The invention is the abluent for the high molecular pollutant which is mixed by the 5-20% potassium hyperchlorate, 1-5% the concentrated sulfuric acid, the greasing additive 4-15%, the 0-25 Pereqa 5-15%, the ferrous sulfate 6-20% and the distilled water 40-70%. The abluent has the simple match and low cost, the residue is not dangerous to the operator and the environment.

Description

technical field [0001] The invention belongs to a cleaning agent and a preparation method, and particularly relates to a cleaning agent for macromolecular pollutants and a preparation method. Background technique [0002] High molecular polymers are widely used in thickening, flocculation, colloid stabilization, drag reduction, bonding, film formation, scale inhibition, gelation and biomedical materials. Especially in industrial sectors such as water treatment, papermaking, mining, coal washing, metallurgy and oil extraction, its usage is increasing day by day. In the process of oil extraction, it is used as a precipitation agent for drilling mud, a purifying agent for oily sewage treatment, and an oil displacement agent for tertiary oil recovery. Practice has proved that injecting polymers into oilfields suitable for polymer flooding can produce at least 150 times more crude oil than the injection amount of polymers. With the wide application of polymers in oilfield drill...

AI Technical Summary

Problems solved by technology

With the wide application of polymers in oil field drilling and production, its production scale is continuously expanding. During production, transportation, storage and use, when it is scattered and meets water, it will form a sticky and smooth film, which will cause operators to slip and fall. Injury, damage to transportation and storage vehicles and the safety of warehouse staff, especially in the process of oil production, due to the injection of polymers, oil production equipment will also be seriously fouled, resulting in premature failure of equipment production and shortening the service life of equipment , causing great economic losses to the enterprise

[0003] The polymer is a hard glassy solid at room temperature, with a density of 1.302g / cm3 at 23°C, a glass transition temperature of 153°C, and a softening temperature of 210°C. It is easily soluble in water at room temperature, and becomes uniform and transparent after being dissolved in water. Liquid, when the concentration of the solution is higher than 10%, the polymer may have a gel-like structure due to the intermolecular hydrogen atom bonding, which is sticky and smooth, causing serious safety hazards to production operators, transportation vehicles, and storage management personnel. In addition, the strong adhesion of the polymer will form a hard polymer film on the surface of submersible equipment, downhole tools, etc., directly resulting in an increase in the number of equipment maintenance and a shortened service life. , a serious waste of manpower and material resources
