Embodiment Construction

[0030] The following detailed description is merely exemplary in nature and is not intended to limit the various embodiments or their application and uses. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description. The accompanying simplification is achieved by eliminating the bulk of equipment normally employed in processes of this nature such as vessel internals, temperature and pressure control systems, flow control valves, recirculation pumps, etc. (these are not specifically required to illustrate the performance of the present invention). picture. Furthermore, the description of the methods of the present invention in the context of specific figure embodiments is not intended to limit the invention to the specific embodiments described herein.

[0031] As shown, the process flow lines in the figures may be referred to interchangeably as, for example, lines, conduits, branches, distributors, s...

Abstract

A process and apparatus for maximizing production of heavy naphtha from a hydrocarbon stream are provided. The process comprises providing a light cycle oil stream comprising mono-aromatics, di-aromatics and tri-aromatics to a hydrotreating reactor. The light cycle oil stream is hydrotreated in the presence of a first hydrogen stream and a hydrotreating catalyst in the hydrotreating reactor operating at hydrotreating conditions to saturate the di-aromatics and the tri-aromatics while minimizing the saturation of mono-aromatics and provide a hydrotreated effluent stream. At least a portion of the hydrotreated effluent stream and a kerosene stream are hydrocracked in a hydrocracking reactor operating at hydrocracking conditions in the presence of a second hydrogen stream and a hydrocracking catalyst to provide a hydrocracked effluent stream. At least a portion of the hydrocracked effluent stream is then fractionated to provide the heavy naphtha.

Description

technical field [0001] The field relates to methods and apparatus for producing naphtha. More specifically, the technical field relates to the hydrocracking of blends of light cycle oil and kerosene to produce heavy naphtha. Background technique [0002] At present, there is an increasing tendency worldwide to shift from fuel mode to petrochemical mode. Refiners are taking every opportunity to maximize petrochemical production. One such opportunity is the production of petrochemicals from relatively low-value hydrocarbon or waste hydrocarbon streams from existing processes. Refiners are working hard to convert this range of hydrocarbons into valuable petrochemicals. [0003] FCC technology is currently being used in refineries to upgrade atmospheric and / or vacuum residues. However, FCC reactors also produce some waste streams, such as light cycle oil (LCO), along with the upgraded hydrocarbons. As the use of FCC technology increases, the production of waste LCO streams ...
