The present invention relates to commercial unit high temperature erosion corrosion test, specifically a kind of high-temp high-flow-speed outwash experiment equipment that is used for the industrial manufacture process device.
The equipment that runs on fields such as petrochemical complex, medicine, electric power, food industry runs into the high temperature erosion problem through regular meeting.For example, in petroleum refining industry, just exist the high temperature erosion problem of naphthenic acid and sulfide, this problem has perplexed a whole world oil refining nearly century of circle, is not solved yet so far.In China, increase along with petroleum refining industry import middle-eastern crude proportion, and the further degree of depth exploitation in domestic oil field, sulfur content and acid number can raise gradually in the crude oil, as not taking corresponding technical measures and countermeasure, will make China's oil refining industry face more and more severeer equipment corrosion problem.
The equipment corrosion problem in the petroleum refining industry and the on-stream time and the cost of enterprise are closely related.Because the corrosive medium kind complexity in the crude oil, influence factor is numerous, and simultaneously, in oil refining apparatus, the place that high temperature corrosion takes place often also is accompanied by the high flow rate factor.Understand fully the effect in material corrosion of each corrosive medium and influence factor, workload and difficulty all are very big.The high-temperature high-flow rate erosion corrosion that is caused by naphthenic acid in the crude oil and sulfide always is the emphasis of oil refining industry research in the world.At present, the INTERCORR.INTERNATIONAL of the U.S., INC.Just began one's study from 1993 and to seek the integrated approach that crude oil corrosivity is estimated, now obtained the subsidy of 650,000 dollars of 21 energy companies in the whole world, its research contents comprises: the type of naphthenic acid, content; H
2S concentration; Temperature; Flow velocity (0～70m/s) and alloy content (wherein the high temperature erosion of naphthenic acid and sulfide is one of its research contents for 0～24%Cr, factor such as 0～6%Mo).The research institution of some scientific research institutions and manufacturing enterprise had once carried out a large amount of investigation to all kinds of corrosion and protection question in the oil refining environment both at home and abroad, though obtained some data, experience, but major part is according to corrosion or the at the scene hanging test data that get of process units in the time between overhauls(TBO), because any refinery all can not the same or analogous crude oil of long-term refining, so the data of hanging test can't reflect in the crude oil that different factors are to the corrosion proof influence of material in the various corrosive mediums.Then can will influence corrosion proof each factor of material separately or combine and study in the laboratory, so that more scientifically investigate in crude oil and the cut thereof various corrosive mediums in aspect and the corrosion proof mutual relationships of material such as temperature, flow velocity, concentration and material metallurgy factors.Now, except that these lacing film data, also many rotation under quiescent conditions or in autoclave of existing laboratory data got.And rotating conditions also can not really reflect the erosion corrosion behavior of material under the high-temperature high-flow rate condition in static and the autoclave.Therefore designing a cover and can simulate the experimental provision of high-temperature high-flow rate media environment, be not only the demand of high-temperature naphthenic acid and sulfide erosion corrosion in the research oil refining apparatus, also is the demand of the erosion corrosion under the high-temperature high-flow rate condition in other industrial environments of research.
Owing to there is not to carry out the relevant device of high temperature erosion experiment at present, thus people under selecting these high-temperature high-flow rate environment, use equipment and materials the time, can only use normal experiment device (static or low flow velocity) to come selection, or the dependence experience is come selection.Will certainly produce selection consequence improperly like this, can cause the certain economic loss to society, serious also can cause human casualty accident.The simulation that will realize high temperature erosion-corrosion environment in the laboratory is very difficult.And owing in the high temperature erosion-corrosion environment in some production process, have inflammable and explosive medium, the high temperature erosion that therefore will carry out under these environment is particularly difficult.
Also do not have to carry out the situation of the device of high-temp high-flow-speed outwash experiment at present at China, the purpose of this invention is to provide a kind of high-temp high-flow-speed outwash experiment equipment that can simulate high-temperature high-flow rate condition in the industrial environment, be used for industrial manufacture process device equipment and materials high-temperature medium erosion test.
