Problems solved by technology

[0004] However, those skilled in the art have found some problems during the actual use of the above-mentioned device. The more obvious one is that in the process of oil flowing down along the outer wall of the gasification plate, although most of the oil will directly flow down to the tower The bottom of the body cavity, but a small part of the oil is in direct contact with the surface of the gasification plate, so the flow speed is relatively slow. At this time, this part of the oil will form an oil film on the surface of the gasification plate, which will cause the subsequent crude oil containing the emulsion to be unable to directly In contact with the gasification plate, heat exchange can only be carried out through the oil film and the gasification plate. Although the demulsification and dehydration effects can also be achieved, compared with direct contact with the gasification plate, the demulsification and dehydration efficiency is lower

Embodiment 1

[0024] The present invention provides such Figure 1-5 The shown a kind of crude oil delightening hydrocarbon and demulsification device comprises a distillation tower 1, and the inside of the vaporization hood 15 in the distillation tower 1 is provided with a first drive mechanism 2, and the first drive mechanism 2 in the first drive mechanism 2 The side of the sealing cover 21 is fixedly arranged through the oil inlet pipe 3, and the oil inlet pipe 3 runs through the bottom of the tower body 11 in the distillation tower 1 and extends to the inside of the vapor phase outlet pipe 12 to be fixedly connected with the sealing cover 21. The first driving mechanism 2 The impeller 23 in the middle is pushed by the raw material oil input through the oil inlet pipe 3, and drives the rotating shaft 22 to rotate. The top end of the first driving mechanism 2 is connected to the second driving mechanism 4 by transmission. An oil film scraping mechanism 5 is fixed on the top of the outer s...

Embodiment 2

[0035] Different from the above embodiment, the rotating plate 51 in the oil film scraping mechanism 5 is fixedly connected with an emulsion uniform mechanism 6, and the vibrating rod 66 in the emulsion uniform mechanism 6 is in the oil film scraping mechanism 5. When the rotating plate 51 rotates, it rotates synchronously, and then stirs the oil liquid inside the preheating pipe 14 in the distillation tower 1 in the horizontal direction. The rod 63 is pushed so that the vibrating rod 66 vibrates the oil inside the preheating pipe 14 in the distillation column 1 from the vertical direction.

[0036] like Figure 5 As shown, the emulsion uniform mechanism 6 includes a second return spring 61 , a lifting plate 62 , a second trigger rod 63 , a lifting rod 64 , an annular plate 65 and a vibrating rod 66 .

[0037] More specifically, the second return spring 61 is fixed on the left side of the bottom of the rotating plate 51, the lifting plate 62 is fixed on the bottom of the seco...

Abstract

The invention discloses a device for removing light hydrocarbon and emulsion from crude oil, and relates to the technical field of crude oil processing, wherein the device comprises a distillation tower; a first driving mechanism is arranged on the inner side of a gasification cover in the distillation tower, and an oil inlet pipe is fixedly arranged on the side face of a sealing cover in the first driving mechanism in a penetrating mode; the oil inlet pipe penetrates through the bottom of a tower body in the distillation tower and extends into a vapor phase outlet pipe to be fixedly connected with the sealing cover; and the top end of the first driving mechanism is in transmission connection with a second driving mechanism, and an oil film scraping mechanism is fixedly arranged at the top of the outer side of a rotating shaft in the first driving mechanism. According to the invention, an oil film formed by residual oil on the surface of the gasification cover can be scraped in the crude oil treatment process, so that the subsequent crude oil can be directly removed from the gasification cover, and the demulsification and dehydration efficiency is further ensured; and meanwhile, the emulsion can be more uniformly distributed in the crude oil, and the situation that local emulsion is too much or too little during subsequent heating is avoided.

Description

technical field [0001] The invention relates to the technical field of crude oil processing, in particular to a device for removing light hydrocarbons and emulsions from crude oil. Background technique [0002] In oil and gas fields, when the crude oil produced from the oil well is collected and transported, it is necessary to use a crude oil stabilization tower to remove volatile light hydrocarbons such as methane, ethane, and propane in the oil, so as to reduce the evaporation loss of crude oil. Most of the development of water injection oil fields The time is carried out in the medium and high water content period (20-70% water content in crude oil). Most of the water in crude oil forms a stable water-in-oil emulsion with oil. In order to ensure the normal operation of crude oil transportation and processing, it is necessary to Water-containing crude oil is subjected to demulsification and dehydration treatment. The most official dehydration method currently used is the c...
