Description

Petroleum high-viscosity hard component curing and forming equipment

Technical Field

The utility model relates to a high hard component solidification former of oil, especially a high softening point pitch solidification former that is used for solvent deasphalting device separation to obtain.

Background

With the reduction of the recoverable reserves of the light oil and the continuous improvement of the oil exploitation technology, the proportion of inferior heavy oil supply in the 21 st century is continuously increased, and the development of ultra-heavy oil in Venezuela, oil sand asphalt in Canada and the like is of great significance. The part of crude oil has the remarkable characteristics that: the specific gravity is large, the viscosity is high, the material does not flow at normal temperature, and the storage and the transportation are difficult; the asphalt, metal content and carbon residue value are high, a series of problems of equipment coking, catalyst inactivation, difficult product quality reaching the standard and the like are brought to the processing treatment process, and the fluidity and the oil quality are improved by a treatment means, so that the energy utilization efficiency and the economic benefit of the development process are improved.

The composition analysis shows that the extra heavy oil contains C7 insoluble asphaltene with the proportion of 5-20% or even higher, the substance is used as a carrier of viscosity and density, from the aspect of existing form, the substance is peptized in a system in a solid-like form, and simultaneously, a cementing aggregation center is formed and is associated with colloid with strong polarity to form a molecular group, so that the transportability of the whole system becomes worse. Therefore, asphaltene conversion or removal is the first choice to reduce oil sand bitumen oil viscosity and increase the oAPI. Based on the above recognition, such raw materials can be considered as two parts: one part is liquid phase oily component, the other part is solid phase asphaltene component formed by association of asphaltene and strong polar colloid, physical separation technology is adopted to separate the oily component from the solid phase asphaltene component, the liquid phase oily component is mixed with diluent to meet the pipeline transportation requirement, and the asphaltene component adopts solid transportation mode, and the 'mass transportation by mass' mode conforming to the inherent property of the substance is undoubtedly more economical and reasonable from the aspects of material and energy input. The other key point is that although the asphaltene component is enriched with elements such as metal, carbon residue and the like which are unfavorable for the storage, transportation and refining processing processes, the asphaltene component has high molecular weight, good adhesion performance and excellent high-temperature performance, and can be developed into high-value products for resource utilization.

Petroleum contains asphaltene high molecular compounds, which brings great difficulty to storage, transportation, processing and utilization. It can be separated by solvent extraction and processed according to its properties to form a separate highly viscous and hard component. Based on the basic principle, CN 2018111195459.6 discloses a process and a system for the comprehensive treatment and modification of overweight heavy oil. In the solvent extraction separation process, under the same condition, aiming at the product development and utilization requirements, the efficient solidification and molding after two-phase separation is an effective solution. The high-softening-point asphalt is a high-viscosity medium with special properties, has poor fluidity in a wide temperature range and can be adhered to each other at a lower temperature, so that no special curing and forming equipment for the high-softening-point asphalt exists in the market at present.

In the process of solvent extraction and separation, by utilizing the principle of similarity and intermiscibility, raw materials are separated into two layers by solvent extraction, an extract phase is distributed in an upper layer, a raffinate phase is distributed in a lower layer, the two layers are respectively stripped to respectively form deasphalted oil and deoiled asphalt, so that the solvent is separated from a final product. However, due to the principle of similar phase dissolution, a small amount of light hydrocarbon solvent is inevitably carried in the stripped liquid deoiled asphalt. In the process of deoiled asphalt dry granulation, the solvent gasification can cause the bubbling of asphalt particles, influence the quality phase of the asphalt particles and reduce the bulk density of the asphalt particles; in the wet granulation process, bubbles in the asphalt particles are broken to leave pits on the surface, and a large amount of water is adsorbed, so that the asphalt particles are difficult to dry, and the service performance of the asphalt particles is affected.

US7964090 discloses a process for upgrading heavy oil by gasification using SDA, the DOA is transferred into a gasifier by solvent entrainment to generate syngas, which converts DOA in situ, but a large amount of solvent is consumed in the gasifier, resulting in a large loss of value. CN101203586A and CN105189710A propose methods for upgrading heavy oil such as bitumen by using mixed hydrocarbon as solvent, which can separate components such as oil, water and asphaltene, but lack technical measures for regulating and controlling product quality. CN1891784A discloses a method and a treatment system for realizing deep step separation of heavy oil by coupling raffinate residue granulation, the scheme adopts light hydrocarbon with higher carbon atom number as a solvent to obtain DAO with higher yield, and the DAO is dispersed into solid particles by introducing a dispersion solvent into a DOA phase and spraying rapid phase change dispersion, so that the DOA and the solvent are separated in a gas-solid separator, the process needs to be implemented under the condition that the DOA softening point is high enough, and the obtained powdery particles have the moisture absorption and bonding tendency. CN103102894A discloses a device and a method for recovering solvent by granulation of deoiled asphalt with high softening point, which is to granulate the deoiled asphalt with high softening point from the bottom of solvent deasphalting tower by screw extrusion system, and directly introduce the granular deoiled asphalt into deoiled asphalt solvent enrichment chamber. The top of the solvent enrichment chamber is provided with a solvent gas recovery pipeline and is communicated with a solvent recovery system, facilities such as a deoiled asphalt solid particle water inlet slideway and the like are arranged in the solvent enrichment chamber, the granular SDA falls into cooling water after enough time for releasing the solvent, and the method solves the problem of recovering the asphalt solvent with high softening point, but generates a large amount of sewage and needs additional treatment.

Liquid containing gas or easily gasified components enters a Venturi tube 1-3 through a gas-liquid inlet tube 1-2 and is sprayed into a liquid collecting tank 1-4 in a degassing tank 1-1 at a certain pressure, due to sudden pressure change, a large amount of gas or easily gasified components dissolved in the liquid are desorbed from the liquid, and the first degassing of the liquid is realized between the outlet of the Venturi tube 1-3 and the surface of the liquid collected by the liquid collecting tank 1-4; the gas-liquid separation is limited due to the small surface area of the liquid during the first degassing. In order to further improve the degassing efficiency, the liquid which is collected by the liquid collecting tanks 1-4 and is subjected to the first degassing flows downwards to enter the distributor, and the purposes of rectifying and uniformly redistributing the liquid subjected to the first degassing are achieved by means of inclined plates and distribution plates of the distributor.

Liquid flowing down from the distributor uniformly flows down along the multilayer conical surface of the gas-liquid separator 1-5 in a radial shape, and secondary continuous degassing is carried out; because the liquid flow channel of the gas-liquid separator 1-5 is a gap of a plurality of layers of conical surfaces, the secondary degassing surface is obviously increased, and good conditions are created for strengthening the liquid-gas degassing.
