Abstract
An apparatus and a method that increase the concentration of recycled hydrogen in the hydrogenation unit are disclosed having a hydration separation unit included between the high-pressure separator and hydrocracking reactor. A part of the recycled hydrogen contacts with the water-in-oil microemulsion to form hydrates from which the light hydrocarbon components are removed. The gas flow entering into the hydration separation unit is present in amount of 20%˜100% of the total gas flow coming from the high-pressure separator; the water-in-oil microemulsion, in which the volume ratio of oil and water is 1:1 to 5:1 may increase hydrogen partial pressure in the reactor and thus upgrade the performance of hydrogenation.
