Background technology
Carrying the top part corrosion of High Temperature High Pressure multiphase medium pipeline is a kind of common phenomena, for example contain certain moisture in oil and gas industry collection and course of conveying oil, the rock gas, when the medium that contains moisture flows in pipeline, if these media can not be full of whole pipe, hole appears in conduit upper, the temperature at pipeline top often is lower than in the pipeline other position, and the water vapour that the water evaporates in the medium goes out condenses at the top of pipeline, contains CO in medium
2Under the situation of gas, CO
2Gas can enter in the water vapour, thereby causes corrosion occurring at the position of water recovery.At present, also do not have a kind of analogue experiment installation of pipeline top part corrosion, limited the mechanism of this corrosion phenomenon, the research of rule, can not estimate the inhibition efficiency that suppresses or prevent the corrosion inhibiter of pipeline top part corrosion effectively.In the work in the past, the method that hangs with test button in the atmosphere of employing in high temperature and high pressure kettle is carried out the simulation experiment study of pipeline top part corrosion, but because test button its temperature in atmosphere is consistent with the corrosive liquid medium, therefore the moisture that condenses on test button seldom, and sample is static, and is bad to the flow simulation of the pipeline top part corrosion that Korrosionsmedium caused of pipe interior.
Summary of the invention
The object of the present invention is to provide high-temp high-pressure condensation water corrosion simulated experiment device, carry the inhibition efficiency of corrosion regularity, mechanism and evaluation vapour-phase inhibitor that the pipeline upper water devaporation of heterogeneous fluid causes for research, provide a cover can simulate the experimental provision of pipeline top part corrosion.This experimental provision can be simulated the caused top part corrosion phenomenon of condensing of the inner surface of pipeline top low-temperature space water vapour of carrying high-temperature, high pressure fluid easily.
The inventive system comprises: high temperature and high pressure kettle, control box, condenser, gas cylinder and magnetic driving equipment.Magnetic driving equipment (10) is connected by bolt with autoclave lower cover (8), and the middle sealing gasket of placing seals.Be connected with bolt between gas cylinder wireway and the autoclave draft tube 3.Be welded to connect between condenser 18 and the cooling water outlet pipe 1, cooling water outlet pipe 1 passes autoclave loam cake 13, nut with autoclave loam cake 13 tops is fastening with rising pipe 1 and autoclave loam cake 13, seals by O-ring seal between rising pipe 1 and the autoclave loam cake 13.Control box is connected with autoclave 21 usefulness leads.Device adopts magnetically-actuated, and in autoclave 21 inside, the airtight container 15 of the aqueous medium of the heat conduction of filling is arranged at the top of turning axle 20, and the outside surface of airtight container 15 is arranged sample 5.The stationary apparatus 22 of cooling usefulness is arranged in the inside of airtight container 15, and inside is connected with recirculated cooling water, and the temperature of chilled water is measured by the temperature sensor 2 in the airtight container 15.Wherein, the surface in contact of the rotary condenser 18 that is fixed together with turning axle 20 and static airtight container upper cover plate 14 is through Carburization Treatment, and the contact sealing prevents that water in the condenser 18 is owing to high speed rotating overflows.
Cooling water inlet pipe 11 is connected with cyclic water tank with cooling water outlet pipe 1, has water pump that chilled water is circulated in pipeline in the cyclic water tank.Sample 5 is placed at the outside surface of condenser 18, and condenser 18 can rotate.Magnetic driving equipment 10 drives condenser 18 by rotating shaft, thereby makes sample 5 rotations.The autoclave control box can be controlled the temperature in the autoclave 21 and the rotating speed of sample 5, and shows the temperature in heat-conductive water and the autoclave 21.Magnetic driving equipment 10 is simplified, and the autoclave control box omits in Fig. 1.The volume of autoclave is 4 liters, and maximum operating temperature is 160 ℃, and maximum working pressure (MWP) is 2MPa.
The invention has the advantages that: can cool off sample by circulating cooling liquid, make the temperature of specimen surface significantly be lower than the interior temperature of high temperature and high pressure kettle, thereby make the surface condensation of water vapour, specimen surface is corroded, simulate the corrosion situation at pipeline top well at the rotation sample.
Description of drawings
Fig. 1 is a structural representation of the present invention.Wherein, cooling water outlet pipe 1, temperature sensor 2, draft tube 3, heating and heat-insulating device 4, sample 5, chilled water is by hole 6, temperature detecting resistance 7, autoclave lower cover 8, holes probe 9, magnetic driving equipment 10, cooling water inlet pipe 11, escape pipe 12, autoclave loam cake 13, airtight container upper cover plate 14, airtight container 15, autoclave wall 16, taphole 17, condenser 18, cooling water pipe 19, turning axle 20, autoclave 21, the stationary apparatus 22 of cooling usefulness.
Embodiment
The lower cover 8 of magnetic driving equipment 10 of the present invention and autoclave is connected by bolt, middlely seals with sealing gasket.Spiral shell links and connects between gas cylinder wireway and the autoclave draft tube 3.Be welded to connect between condenser 18 and the cooling water outlet pipe 1, cooling water outlet pipe 1 passes autoclave loam cake 13, and rising pipe 1 is fastening with autoclave loam cake 13, uses bolted between rising pipe 1 and the autoclave loam cake 13, and seals by O-ring seal.Open kettle cover 13, pour experiment into and use solution in still, the position of liquid level of solution will be lower than the lower surface of condenser 18.Sample 5 is placed on the specimen mounting of annular, in condenser 18, pour the heat-conductive water medium into, cover kettle cover 13, airtight container upper cover plate 14 closely contacts with condenser 18, and the water that heat conduction is used in the airtight container 15 when preventing condenser 18 rotations is because centrifugal action throws away condenser 18.By the solution in the resistance wire heating high-pressure still in the heating and heat-insulating device 4, feed experiment by draft tube 3 and use gas (as CO
