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.The loam cake 13 of magnetic driving equipment 10 and autoclave is connected by bolt, 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 14, nut with autoclave loam cake 14 tops is fastening with rising pipe 1 and autoclave loam cake 14, seals by O-ring seal between rising pipe 1 and the autoclave loam cake 14.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 is arranged sample 5.The stationary apparatus 22 of cooling usefulness is arranged in the inside of sealing water receptacle, 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 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) rotation.The autoclave control box can be controlled the interior temperature of autoclave (21) and the rotating speed of sample (18), 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.
