Abstract

The invention relates to a novel floatation agent composition and belongs to the technical field of the petroleum industry. The novel floatation agent composition comprises, by mass percentage, 1%-30% of alkyl tertiary amine quaternary ammonium salt, 1%-30% of trimethylene group[(alkyl dimethyl amine/alkyl dimethyl amine) chlorine/ammonium bromide], 1%-10% of nonylphenol polyoxyethylene polyoxypropylene ether, 1%-10% of N,N'-dilauroyl-ethylenediamine-sodium diacetate, 1%-30% of ethylene group di(alkyl polyethylene group ammonium chloride), 0%-15% of a pour point depressant and the balance water. The novel floatation agent composition has the beneficial effects that the dosage is little, few residues exist, the separating efficiency is high, and corrosion to pipeline equipment is low.

Description

technical field [0001] The invention belongs to the technical field of petroleum industry, and in particular relates to a novel flotation agent composition. Background technique [0002] Air flotation technology is widely used in the field of water treatment. It belongs to a method of solid-liquid and liquid-liquid separation. When there are micro-bubbles in the wastewater, part of the suspended matter adheres to the surface of the bubbles and floats to the water surface to form a foam layer. The foam layer is suspended to realize separation and removal of suspended solids. However, hydrophilic suspended matter is not easy to float up with the air bubbles. It is necessary to add a flotation agent in the air flotation process to change the wettability of the surface of the suspended matter and increase the hydrophobicity so that it is easier to absorb on the surface of the air bubbles and float up to achieve purpose of separation. [0003] At present, the most commonly used...
