Embodiment 1

[0229] Based on Comparative Example 1, the hydrogen consumption of the circulating hydrogen compressor AR1-RHC based on the pre-hydrofining reaction process AR1 of the 30,000-ton / year heavy benzene hydro-upgrading unit ARU (3520-4000Nm 3 / h) Only the new hydrogen compressor FHC rated flow 23000Nm 3 The condition of 15.3~17.4% of / h adopts the hydrogen compressor combination method of the hydrogenation conversion process of a kind of different hydrocarbon feedstock of the present invention, does not set up the special cycle hydrogen compressor AR1-RHC, by enlarging the united new hydrogen compressor FHC The first-stage flow rate, using the first-stage return hydrogen as the hydrogen raw material for the heavy benzene pre-hydrogenation reaction process AR1, forms an integrated new hydrogen compressor unit TFHC. After integrating the new hydrogen compressor unit TFHC and considering the dynamic balance of compressor stages, the pressure parameter scheme is shown in Table 7.

Embodiment 2

[0239] Based on Example 1, the raw material scale of the anthracene oil distillate hydroreforming unit BRU is reduced from 150,000 tons / year to 75,000 tons / year, and the weight hydrogen consumption of the raw material oil of the device BRU is 8.6%, that is, 806.25kg / h, 8964Nm 3 / h;

[0240] The raw material scale of heavy benzene hydro-upgrading unit ARU is increased from 30,000 tons / year to 60,000 tons / year, and the weight hydrogen consumption of raw material oil of ARU is 4.9%, that is, 367.5kg / h, 4086Nm 3 / h;

[0241] United new hydrogen compressor FHC rated flow rate 13050Nm 3 / h, rated flow rate 14500Nm 3 / h;

[0242] Based on the pre-hydrofining reaction process AR1 of the 60,000-ton / year heavy benzene hydro-upgrading unit ARU, the hydrogen consumption of the circulating hydrogen compressor AR1-RHC (7040-8000Nm 3 / h), the rated flow rate of the new hydrogen compressor FHC is 14500Nm 3The condition of 48.6~55.2% of / h adopts the hydrogen compressor combination metho...

Abstract

The invention relates to a combination method for hydrogen compressors used in the process of hydroconversion of different raw hydrocarbon materials. According to the invention, under the conditions that the operation pressure in the hydrogenation process AR1 of a first raw hydrocarbon material AF is lower than the operation pressure in the hydrogenation process BR of a second raw hydrocarbon material BF and that the volume of hydrogen used in the hydrogenation process AR1 is lower than the volume of fresh hydrogen used in the hydrogenation process BR, hydrogen AH01 used in the hydrogenation process AR1 of the first raw hydrocarbon material AF comes from interstage hydrogen material flow HX of a fresh hydrogen compressor BC used in the hydrogenation process BR of the second raw hydrocarbon material BF. The method provided by the invention can omit a special circulation hydrogen compression unit for pre-hydrorefining process AR01 in a conventional process and has the advantage of substantial conservation of investment and energy.
