Abstract
The inventive method for controlling corrosion of the refinery metal walls produced by naphthenic acids consists in using alkyl polysulfide radical containing from 2 to 5 carbon atoms.
Description
The present invention relates to the process field of sour crude oil in the refinery.More specifically, the objective of the invention is a kind of refining unit (unit é de raffinage) corroding method that prevents to handle sour crude oil, this method comprises uses specific polysulfide.
When oil refinery need be handled some described sour crude oil, they may run into serious etching problem.These sour crude oil mainly contain naphthenic acid, and they are the roots that produce this very special corrosion phenomenon, because it occurs in the liquid medium of non-Ampereconductors.These naphthenic acid are corresponding to the saturated cyclic hydrocarbons that has one or more carboxyls.According to ASTM D664-01 standard, measure definite crude oil acidity by stdn.This acidity with in and the needed potassium hydroxide mg of 1g oil numerical table show, be referred to as TAN (total acid value).Those skilled in the art know, being higher than 0.2 crude oil TAN qualitative is tart, and it may cause damage in refinery's equipment.
Local condition is greatly depended in this corrosion reaction, for example as the temperature of relevant device wall and metallic character, the space velocity of hydrocarbon, the existence at gas/liquid interface.Therefore, even after the refiner carries out extensive work with regard to this problem, expect that great corrosion reaction and location thereof also can run into great difficulty.
The way of this etching problem of a kind of industrial solution is to use the equipment of being made by stainless steel, in other words uses by iron alloy, particularly the equipment made of the alloy of iron and chromium and molybdenum.Yet this terms of settlement is still seldom used because of cost of investment is high.Refinery in addition,, but also needs suitable Infrastructure, so also should preferably consider this selection when designing because these stainless mechanical propertys are not so good as to use usually the mechanical property of carbon steel.
Therefore, handling these sour crude oil has the result of these technological difficulties to be, these crude oil are sold to the refiner with the price level that is lower than benchmark crude.
The terms of settlement that these refiners adopt another kind to handle the sour crude oil problem in the reality is to dilute this sour crude oil with another kind of nonacid crude oil, thereby obtain harmonic(-)mean acidity, for example be lower than the 0.2TAN threshold value, in this case, the concentration of naphthenic acid should be hanged down is enough to reach acceptable corrosion speed.Yet this way still has certain scope.In fact, the TAN of some sour crude oil is higher than 2, makes the top limit of using these sour crude oil reach like this and enters 10% of refinery crude total amount at the most.In addition, some blends of crudes even appearance and expectation reverse effect sometimes after dilution, i.e. naphthenic acid accelerated corrosion reaction.
The another kind of method that prevents this etching problem is to add chemical additive in pending sour crude oil, and this additive can suppress or prevent the metallic walls of chemical erosion relevant device.Point out that with using the front method of special steel or alloy compares, this method is very economical often.
Experimental study, for example (" corrosion " (Corrosion), in November, 1998, the 54th volume, o. 11th, the 922nd page) experimental study, imagination is added (0.1%) hydrogen sulfide on a small quantity in order to reduce the corrosive nature of naphthenic acid to Turnbull in this crude oil.Yet this terms of settlement is not useable in the refinery, because hydrogen sulfide at room temperature is highly toxic, makes like this these leak the result and all become extremely dangerous that this has also limited the use of hydrogen sulfide.In addition, under higher temperature, the corrodibility that hydrogen sulfide itself also becomes very high, it also can make general corrosion phenomenon worsen more in other place of refinery.
US 5 182 013 has described to solving the sulfocompound that this same etching problem uses other, promptly contains the alkyl polysulfide of 6-30 carbon atom.
Patent EP 742 277 has described the restraining effect of trialkyl phosphates and organic polysulfide and usefulness.US 5 552 085 recommends to use sulfo-P contained compound, for example organosulfur substituted phosphate or thiophosphite.Patent AU 693 975 disclosed trialkyl phosphates and with the mixture of lime neutral phenol red phosphide as inhibitor.
Yet, because organophosphorus compound is handled very thorny because of its high toxicity.In addition, they are poisonous substances that hydrotreating catalyst is installed from the hydrocarbon-fraction of normal pressure and vacuum distilling for purifying.Owing to this two reasons at least, organophosphorus compound is unsatisfactory in the refining Application for Field.
Astoundingly, people have found to use the organic polysulfide of certain kinds, and each alkyl carbon atoms number of these poly-alkyl sulfur compoundss is 2-5, and they can suppress the corrosion of these naphthenic acid, the height of the present known organic polysulfide of its efficiency ratio, nor need to add phosphorous inhibitor.
Therefore, the objective of the invention is a kind of method that prevents naphthenic acid (acides naphth é niques) corrosion refining unit metallic walls, it is characterized in that this method comprises toward containing hydrocarbon compound with one or more following formulas that add significant quantity in this device processes hydrocarbon stream:
