Problems solved by technology

It is difficult for oil-soluble vanadium inhibitors to disperse evenly with Orim oil, and even stratification occurs
The existing water-soluble vanadium inhibitors are traditional MgSO 4 Aqueous solution and magnesium acetate (such as CN1055110C), although they can satisfy the oil-in-water system of Orim oil, the magnesium content is very low, and cannot solve the problem of high vanadium content in Orim oil

Abstract

The invention relates to a method for preparing a water-soluble vanadium inhibitor. Firstly, a nonionic surface active agent is added into MgO powder, and is uniformly ground; diethylene glycol or glycerin and alcohol and ethyl acetate and other diluents are used to prepare water-soluble organic solution with a certain concentration, and stand for a while after being mixed; the processed MgO powder is added into the organic solution to be sealed, sonic oscillation is performed, the MgO powder in the product is adequately separated and segregated, the prepared vanadium inhibitor suspending liquid is heated and stands for a while in an aqueous thermostat, and then the vanadium inhibitor with good dispersilbility and water solubility can be obtained. The method of the invention is simple, and the prepared vanadium inhibitor has the advantages that the magensium content is high, the stability is good, the clinker after being burnt is loose and is easy to be cleaned, and the output recovery is good.

Description

technical field [0001] The invention relates to a preparation method of a water-soluble vanadium inhibitor. The prepared product is a fuel additive, which can be used to suppress the gas turbine generating set or large boiler using oil-in-water type gas turbine oil such as Orimusion. Molten salt corrosion caused by vanadium impurities in the oil prolongs the service life of the gas turbine or boiler. It belongs to the field of energy and petrochemical industry. Background technique [0002] The oil for oil-in-water gas turbines, such as Orimusion, is made from a naphthenic super-heavy crude oil produced in the Orinoco River Basin in Venezuela, South America, emulsified with an emulsifier and 27%-30% water , The oil droplets are surrounded by surfactants to form a hydrophilic interface film. The asphalt oil particles are generally about 10 μm, in which water is the continuous phase and oil is the dispersed phase. The density is close to that of water, and they are suspended ...
