Embodiment Construction
[0033] The process and effect of the combined hydrogenation method of the present invention will be further described below in conjunction with the examples, but the following examples do not constitute a limitation to the method of the present invention.
[0034] A hydrogenation combination method of the present invention is specifically implemented as follows: raw material oil 1 is mixed with circulating oil 3, and the mixed material and hydrogen gas are mixed in the hydrogen dissolver 4 and then enter the hydrogenation reactor 7, and pass through the first catalyst bed , dissolve hydrogen in the effluent of the first catalyst bed, and pass through the second catalyst bed, dissolve hydrogen and gaseous raw material 6 in the effluent of the second catalyst bed, and pass through the third catalyst bed, hydrotreating reactant flow 9 is mixed with the gaseous raw material 6 in the gas dissolver 23 and enters the supplementary reactor 24, and passes through the first catalyst bed,...

The invention discloses a refinery gas hydrogenation combined process, which includes the following content: (a) residual raw material oil and circulating oil are mixed with hydrogen in hydrogen dissolving equipment, and then enter the hydrogenation catalyst bed in the hydrogenation reactor The reaction is carried out under hydrogenation operation conditions, and gas-dissolving equipment is installed between adjacent catalyst beds; (b) refinery gas and / or hydrogen is mixed and enters any gas-dissolving equipment installed between adjacent catalyst beds, the same as from the previous The reactant stream in the catalyst bed is mixed and enters the next catalyst bed for reaction; (c) The hydrogenation reactant stream obtained in step (b) is mixed with refinery gas and hydrogen in the gas-dissolving equipment and then enters the supplementary hydrogenation reactor The hydrogenation catalyst bed is reacted under the operating conditions of liquid phase hydrogenation; (d) the hydrogenation reaction effluent obtained in step (c) is separated into a gas phase and a liquid phase, and the separated gas phase is further separated after hydrogen sulfide is removed to obtain Hydrogen, refinery gas after hydrotreating. The method is capable of hydrotreating refinery gas and producing hydroresidue at the same time.
Description
technical field [0001] The invention belongs to the hydrogenation process of oil refining technology, and relates to a refinery gas hydrogenation combined processing technology, in particular to a refinery gas hydrogenation treatment and hydrogenation combined hydrogenation residue production method. Background technique [0002] At present, the energy on a global scale mainly comes from fossil energy, among which petroleum is the most important source of motor fuel. Petroleum is a non-renewable energy source. Not only are the resources increasingly depleted, but also the trend of heavy and inferior quality is intensifying. The continuous development of the world economy and increasingly stringent environmental protection regulations require the production of a large amount of light and clean fuels, which require the improvement of the existing refining technology. Add new oil substitutes while improving, and produce products that meet the requirements at the lowest cost. C...
