Embodiment 1

[0092] In a certain factory, there is a heavy oil catalytic cracking unit, which produces acidic water of catalytic cracking unit whose properties are shown in Table 2 (discharged from the reflux tank at the top of the catalytic cracking fractionation tower), and another set of medium-temperature coal tar with a conventional boiling range of 120-485 ° C. Hydroconversion unit with oil as raw material, the hydroconversion unit adopts two-stage hydrorefining and hydrocracking process in series, according to the conventional technical scheme, 6.8500t / h of purified water needs to be used as flushing water in the hydrorefining section, The acidic water produced by the hydrogenation unit whose properties are shown in Table 2 (discharged from the high-pressure separator in the hydrorefining section), according to the conventional process, the total amount of acidic water in the two channels is 12.7770t / h after mixing, and all the acidic water enters the acidic water stripping treatment ...

Embodiment 2

[0102] A set of anthracene oil hydroconversion unit in a factory adopts two-stage processes of hydrofining and hydrocracking. The reaction pressure of the anthracene oil hydrotreating section is 16.8MPa. High-separation gas and hot high-separation oil, the operating pressure of the hot high-pressure separation part is 15.9MPa, and the operating temperature is 280°C. After the hot high-separation gas is cooled to 180°C, it is injected with flushing water, and after further cooling to 48°C, the entry pressure is 15.3MPa and the temperature The cold high-pressure separation at 48°C is partially separated into cold high-separation gas SV, cold high-separation oil SL and cold high-separation water SW.

[0103] Simultaneously the hydrocracking of anthracene oil hydrocracking section produces the property that the low-pressure separator of the fractionation part that produces oil is as table 4 containing hydrogen sulfide low part gas need dehydrogen sulfide, according to the present i...

Abstract

The invention relates to a method for using process water as flushing water of reaction effluent in a hydrocarbon hydrogenation process. The process water containing hydrogen sulfide and / or ammonia and / or hydrocarbon oil is used as the flushing water of the reaction effluent in the hydrocarbon hydrogenation process, so the total quantity of raw material water of water treatment devices such as an oily sewage treatment device or an acidulous water steam stripping device is reduced. In order to enlarging the process water source or reducing the influence of the process water on the quality of oil generated through hydrogenation in the hydrocarbon hydrogenation process, a process water deoiling process is added, oil obtained in the deoiling process can be reused as raw material oil in the hydrocarbon hydrogenation process or to enter hydrocarbon products of a process water generating device. The method is particularly suitable for the design or modification of the hydrogenation process of high-nitrogen-content hydrocarbon oil such as coal tar or shale oil.

Description

technical field [0001] The present invention relates to a method of using process water as the flushing water of reaction effluent in hydrocarbon hydrogenation process, using process water containing hydrogen sulfide and or ammonia and or hydrocarbon oil as flushing water of reaction effluent in hydrocarbon hydrogenation process; The invention relates to a method of using process water as the flushing water of the reaction effluent in the hydrogenation process of high nitrogen hydrocarbons; more particularly the present invention relates to a method of using the process water as the flushing water of the reaction effluent in the hydrogenation process of coal tar or shale oil method. Background technique [0002] The present invention is proposed based on the following conditions: in an oil processing plant with multiple streams of process water containing hydrogen sulfide and or ammonia and or hydrocarbon oil, under the condition of hydrocarbon hydrogenation process, the hyd...
