    摘要: In a hydrocracking process, the product from the first stage reactor passes through a steam stripper to remove hydrogen, H2S, NH3, light gases (C1-C4), naphtha and diesel products. The stripper bottoms are separated from hydrogen, H2S, NH3, light gases (C1-C4), naphtha, and diesel products and treated in a second stage reactor. The effluent stream from the second stage reactor, along with the stream of separated hydrogen, H2S, NH3, light gases (C1-C4), naphtha, and diesel products, are passed to a separation stage for separating petroleum fractions. Preferably, the effluent stream from the first stage reactor is passed through a steam generator prior to the steam stripping step. In an alternate embodiment, the effluent stream from the first stage reactor is passed through a vapor/liquid separator stripper vessel prior to the steam stripping step.
