Description
Technical field
The present invention relates to a kind of environment-friendly type crude oil decalcifying agent, belong to PETROLEUM PROCESSING field, be a kind of suitable in the non-phosphate environment-friendly type crude oil decalcifying agent of the elimination of the metallic element such as calcium, ferrum in middle high calcium quasi-oil.
Background technology
The exploitation in current domestic a lot of oil fields progresses into middle and late stage, and crude oil heaviness is increasingly severe, so that the tenor in the crude oil of output is more and more higher, representational metal ingredient is calcium and ferrum.With Ca2+Content is example, and From Liaohe Heavy Crude calcium ion mass fraction has reached 348 μ g/g；The Sudan Fula-North-3 oil Ca of foreign country2+Mass fraction be surprising 1990 μ g/g, this makes crude oil decalcifying work become being necessary very.
Calcium in crude oil is divided into inorganic calcium and the big class of organic calcium two.Inorganic calcium exists with forms such as calcium chloride, calcium carbonate, calcium sulfate, and organic calcium exists with forms such as calcium naphthenate, fat fat acid calcium, phenol calcium.Generally, the calcium salt in crude oil can also in crude oil electric desalting process because of washing, settlement separate out, and organocalcium compound is soluble in oil and be insoluble in water, be difficult to remove in electro-desalting process.The processing of follow-up crude oil is had a negative impact by this part calcium.Crude oil processing is had more serious impact by Calcium in Crude Oil too high levels, high calcium can deposit in the space of catalyst, reduce its specific surface area, catalyst is made to lose activity, simultaneously for hydrocracking catalyst, too much calcium in crude oil can block the medium channel of beds, makes the pressure drop in reactor increase, and accelerates the deactivated process of catalyst simultaneously；In the Crude Desalting System of decalcification, Calcium in Crude Oil too high levels can increase electrical conductivity so that the electric current in Crude Desalting System increases, and the consumption etc. adding electric energy affects.
The decalcification technic of current main flow mainly can be attributed to chemistry chelating method, chemistry acidic treatment and chemical precipitation method.Chemistry chelating method, method as disclosed in Chinese patent CN1076473, CN87105863, CN10366981, the employing of this kind of method can generate the amino carboxylic acid of water soluble chelate compound, dicarboxylic acids, hydroxy carboxylic acid and its esters with Ca and carry out crude oil decalcifying；Chemistry acidic treatment, method as disclosed in Chinese patent CN1055552, CN1454967, CN1267707, CN1521239, strong acid in organic or inorganic is utilized to carry out the hydrionic principle of strong acid in weak acid displacement with the petroleum acids calcium in crude oil, it is the petroleum acids calcium to remove in crude oil by petroleum acids calcium reduction, shortcoming be strong acid can severe corrosion equipment, there is bigger penetrating odor simultaneously, to shortcomings such as the bad adaptability of crude oil, decalcifying agent consumption are big；Chemical precipitation decalcification, such as Chinese patent CN1120575, CN1054261, method disclosed in CN1760338, this kind of method adopts water soluble sulfate, phosphate generates slightly soluble or water-fast calcium sulfate with the petroleum acids calcium effect in crude oil, calcium phosphate precipitation thing, under the effect of surfactant, it is deposited on aqueous phase and reaches the purpose of decalcification, the decalcifying agent that first shortcoming of this kind of method is phosphoric acid salt contains phosphorus, water pollution can be caused, environmental effect is big, secondly the removal efficiency of calcium is not high, the easy occluding device pipeline of precipitate produced, the industrial residue simultaneously produced needs to process.The present invention relates to a kind of environment-friendly type crude oil decalcifying, the feature of this crude oil decalcifying agent is the calcium that can effectively remove in crude oil, and product is not phosphorous, environmental friendliness.
