Embodiment 1

[0216] The medium and low temperature coal tar produced in the coal-to-semi-coke process is shown in Table 2. The annual processing capacity is 500,000 tons / year, the annual operating hours are 7920, and the quantity is 63132kg / h. In order to separate the light residual oil component to the greatest extent, and simultaneously concentrate the asphaltenes, ash, and particulate matter in the coal tar in the heavy coal tar pitch to obtain a high softening point of the coal charcoal, adopt the present invention, and the operation steps are as follows:

[0217] ①In the first vaporization separation part STEP1, the conditions after heating the raw material F01 are: temperature 380°C, pressure 0.15MPaA, the first separation process is separated into vapor phase V1 (47578kg / h, accounting for 75.4% of the raw material F01) and containing The liquid phase L1 of the residual oil component (15554kg / h, accounting for 24.6% of the raw material F01), the weight content of components with a con...

Embodiment 2

[0227] Based on Example 1, in the vaporized hydrocarbon recovery step STEP4, the vapor phase V3 from the second vaporization separation part STEP3 is condensed to obtain hydrocarbon oil HPF.

[0228] In the hydrogenation step STEP5, the hydrocarbon oil HPF is converted into a hydrogenated oil product through the hydro-upgrading process HP, and the hydro-upgrading process HP includes the hydrofinishing process HT of the hydrocarbon oil HPF, and also includes the separation hydrofinishing process HT The hydrocracking process HC of hydrorefined wax oil HTVGO obtained mainly from hydrocarbon components with conventional boiling points higher than 350°C.

[0229] This example forms a combination process of medium and low temperature coal tar deep drawing and vaporized oil hydro-upgrading process.

Abstract

The invention relates to a method for preparing light oil from heavy oil-containing hydrocarbon material flow, and is suitable for processing medium and low temperature coal tar, deep vaporization of residue fraction can be realized by employing an indirect heating mode, the highest temperature during a heating process is reduced for inhibiting a thermal condensation reaction; in a first vaporization separation part, a hydrocarbon raw material F01 containing vapor phase, liquid phase and residue fraction ZYC is separated to a vapor phase V1 and a liquid phase L1; at least a part of vapor phase V1 taken as a vapor phase material flow V11 to be heated for heating the vapor phase heating part to obtain high temperature gas V2; in a second vaporization separation part, at least a part of liquid phase L1 and at least a part of high temperature gas phase V2 are mixed and contacted, and then separated to gas phase V3 and liquid phase L3, at least a part of residue fraction in the liquid phase L1 is introduced in the gas phase V3 for completing deep vaporization of the liquid phase L1; and the gas phase V3 is condensed to obtain oil product, and then the oil product can pass through a hydrogenation process to prepare clean oil products.

Description

technical field [0001] The present invention relates to a kind of method for producing light oil from the hydrocarbon flow containing heavy oil; Particularly the present invention relates to a kind of method for producing light oil from the low hydrogen content miscella containing heavy oil component; More particularly Specifically, the present invention relates to a method for producing light oil from coal-based oil containing heavy oil components, which is suitable for the processing of medium and low temperature coal tar, and adopts indirect heating to realize deep vaporization of residual oil components (i.e. reduce coal Tar pitch yield) and reduce the maximum temperature of the heating process to inhibit the thermal condensation reaction, and the condensed oil of the steam obtained by deep vaporization can be hydrogenated and modified to produce clean oil. Background technique [0002] In order to illustrate the problem, the present invention divides conventional medium...
