Abstract

The invention discloses a neutralizing corrosion inhibitor. The neutralizing corrosion inhibitor comprises 1%-4% of a dispersing agent, 15%-20% of neutral organic amine, 2%-8% of a tetrahydroglyoxaline compound, 1%-3% of an alkynol compound, 2%-10% of a nitrogen-containing adsorption type corrosion inhibitor, 1%-8% of a synergist, 6%-8% of phenolic resin, 3%-4% of a superfine high-activity zinc solution, 2%-3% of composite ceramic nanometer tungsten oxide, 1%-2% of titanium dioxide and 30%-66% of a solvent. The neutralizing corrosion inhibitor is suitable for corrosion prevention of atmospheric pressure reduction, catalytic cracking and delayed coking devices and the like of petrochemical engineering, and is suitable for processing various kinds of sour crude, tower top condensation and corrosion to a cooling system are avoided, and the function of neutralizing H+ is achieved; and when the atmospheric pressure reduction devices are used, ammonia can be adjusted to be injected or not according to the actual injection amount, and the double effects of neutralizing and corrosion inhibiting are achieved.

Description

technical field [0001] The invention relates to the technical field of preparation of a neutralizing corrosion inhibitor, in particular to a neutralizing corrosion inhibitor. Background technique [0002] The neutralizing corrosion inhibitor is a special neutralizing product developed for the high content of hydrogen sulfide in the corrosive medium of the hydrofining unit, and adopts the mechanism of corrosion inhibition as the main and neutralization as the auxiliary mechanism. This product not only has the function of corrosion inhibition, but also has the double effect of neutralizing and anticorrosion. [0003] The existing neutralizing corrosion inhibitor has poor corrosion inhibition effect, so we propose a neutralizing corrosion inhibitor. Contents of the invention [0004] The object of the present invention is to provide a neutralizing corrosion inhibitor to solve the problems raised in the above-mentioned background technology. [0005] To achieve the above obj...
