Description
Technical field
The present invention relates to a kind of environment-friendly type crude oil decalcifying agent, belong to PETROLEUM PROCESSING field, be that one kind is applied to middle high calcium class
The non-phosphate environment-friendly type crude oil decalcifying agent of the removing of the metallic elements such as Calcium in Crude Oil, iron.
Background technology
The exploitation in many oil fields domestic at present was progressed into the middle and later periods, and crude oil heaviness is increasingly severe, so that
The tenor more and more higher in the crude oil of output is obtained, representational metal ingredient is calcium and iron.With Ca2+Exemplified by content, the Liaohe River
Viscous crude calcium ion mass fraction has reached 348 μ g/g;The Sudan Fula-North-3 oil Ca of foreign country2+Mass fraction to be surprising
1990 μ g/g, this cause crude oil decalcifying work become very to be necessary.
Calcium in crude oil is divided into inorganic calcium and the major class of organic calcium two.Inorganic calcium is in forms such as calcium chloride, calcium carbonate, calcium sulfate
In the presence of organic calcium exists in forms such as calcium naphthenate, fat resin acid calcium, phenol calcium.Generally, the calcium salt in crude oil can also be
Because washing, sedimentation separation come out during crude oil electric desalting, and organocalcium compound is soluble in oil and is insoluble in water, in electro-desalting
During be difficult to remove.This part calcium has a negative impact to the processing of follow-up crude oil.Calcium in Crude Oil too high levels are processed to crude oil
There is more serious influence, high calcium can be deposited in the space of catalyst, reduce its specific surface area, catalyst is lost activity,
For hydrocracking catalyst, the excessive calcium in crude oil can block the medium channel of beds, make reactor
In pressure drop increase, while accelerating the deactivated process of catalyst;In the Crude Desalting System of decalcification, Calcium in Crude Oil content
It is too high to increase electrical conductivity so that the electric current increase in Crude Desalting System, add the influence such as consumption of electric energy.
The decalcification technic of current main flow can mainly be attributed to chemical chelating method, chemical acidic treatment and chemical precipitation method.
Chemical chelating method, the method as disclosed in Chinese patent CN1076473, CN87105863, CN10366981, this kind of method uses energy
Crude oil decalcifying is carried out with Ca amino carboxylic acid, dicarboxylic acids, hydroxycarboxylic acid and its esters for generating water soluble chelate compound;At chemical acid
Logos, the method as disclosed in Chinese patent CN1055552, CN1454967, CN1267707, CN1521239 utilizes organic or nothing
Strong acid carries out the hydrionic principle of strong acid in weak acid displacement with the petroleum acids calcium in crude oil in machine, is oil by petroleum acids calcium reduction
Acid removes the calcium in crude oil, have the disadvantage strong acid can severe corrosion equipment, while there is larger penetrating odor, crude oil is fitted
The shortcomings of answering property is poor, decalcifying agent consumption is big;Chemical precipitation decalcification, such as Chinese patent CN1120575, CN1054261,
Method disclosed in CN1760338, this kind of method uses the petroleum acids calcium effect generation in water soluble sulfate, phosphate and crude oil
Slightly soluble or water insoluble calcium sulfate, calcium phosphate precipitation thing, in the presence of surfactant, are deposited on aqueous phase and reach decalcification
Purpose, the shortcoming of this kind of method is that the decalcifying agent of phosphoric acid salt contains phosphorus first, can cause water pollution, and effect on environment is big,
Secondly it is not high to the removal efficiency of calcium, the easy occluding device pipeline of sediment of generation, while the industrial residue produced needs processing.
It is that can effectively remove the calcium in crude oil the characteristics of the crude oil decalcifying agent the present invention relates to a kind of environment-friendly type crude oil decalcifying, and production
Product are not phosphorous, environment-friendly.
