Abstract

The invention discloses a method for preparing a multifunctional water treatment agent derived from a pomegranate bark extract. The method includes that pomegranate barks are smashed and placed into a container, a solvent is added into the container, reflux extraction is performed, the container is cooled to be at the room temperature, an alkylate reagent and an amino reagent are added, warming reflux is performed, finally the container is cooled to be at the room temperature, pomegranate bark powders are filtered out, and a filter liquid is dried by distillation and smashed to obtain the multifunctional water treatment agent which is a brown granular solid. According to the method, prepared products are good in water solubility, high in stability, as the multifunctional water treatment agent, the corrosion inhibition, scale inhibition, iron ion stability and sterilization performances are achieved.

Description

technical field [0001] The invention relates to the technical field of preparation of plant extract derived multifunctional water treatment agent, in particular to a preparation method of pomegranate peel extract derived multifunctional water treatment agent. Background technique [0002] Oilfield water treatment requires the use of various water treatment agents, such as corrosion inhibitors, scale inhibitors, iron ion stabilizers and fungicides. At present, there are many kinds of chemicals used in oilfields, and the dosage is large, and they are mainly artificial synthetic materials, which are not environmentally friendly and renewable. Especially in terms of fungicides, the fungicides commonly used in oil fields are quaternary ammonium salts and chlorine dioxide. Due to the single variety and long-term use, the drug resistance of oil field bacteria has gradually increased. The solution is often to simply increase the dosage of fungicides, which ultimately leads to a vic...
