Problems solved by technology

However, hydrocracking the DAO requires a capital intensive, high-pressure, system to fractionate the large quantity of DAO, especially when intermediate products such as diesel, gas oil, and / or kerosene are preferred.

Abstract

Systems and methods for processing one or more hydrocarbons are provided. A hydrocarbon can be selectively separated to provide one or more finished products and an asphaltenic hydrocarbon using a pretreatment process. The asphaltenic hydrocarbon can be selectively separated to provide a deasphalted oil and one or more asphaltenes. At least a portion of the deasphalted oil can be converted to one or more first products using a first post-treatment process. At least a portion of the one or more asphaltenes can be converted to one or more second products using a second post-treatment process.

Description

BACKGROUND[0001]1. Field[0002]Embodiments of the present invention generally relate to extraction processes for processing hydrocarbons. More particularly, embodiments of the present invention relate to processes for upgrading one or more hydrocarbons using a solvent de-asphalting unit.[0003]2. Description of the Related Art[0004]Solvent de-asphalting (“SDA”) processes have been used to treat residuum (“residual”) oil. Traditional refinery distillation processes separate light hydrocarbon compounds from feedstocks, leaving a large volume of residual oil that is primarily heavy hydrocarbons. SDA processes have been used to treat the heavy hydrocarbons with a solvent to generate asphaltenic and de-asphalted oil (“DAO”) products. The asphaltenic and DAO products are typically treated and / or processed into useful products.[0005]DAO can be economically attractive when downstream treatment facilities such as hydrotreating or fluid catalytic cracking (“FCC”) are adequately sized to process...
