Abstract: Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.

Abstract: The present invention provides a method and a system for preparing fuel using high-acid-value biological grease, which can be processed through triple deoxidization steps, i.e., thermal cracking deoxygenation-catalytic cracking deoxygenation-catalytic hydrodeoxygenation. By use of the method and system of the invention, the raw material of the high-acid-value biological grease can be gradually deoxidized to reduce the acid value and thereby prepare a clean fuel with equivalent fuel components as those obtained from crude oil refining or direct hydrodeoxygenation for biological grease.

Abstract: Disclosed herein are processes for the production of hydrocarbon fuel products from C2-5 alkanes. Methane is converted to ethylene in a methane thermal olefination reactor operating at a temperature of at least 900° C. and a pressure of at least 150 psig, and without a dehydrogenation catalyst or steam. C2-5 alkanes are converted to olefins in a C2-5 thermal olefination reactor operating at a temperature, pressure and space velocity to convert at least 80% of the alkanes to C2-5 olefins. The ethylene and C2-5 olefins are passed through an oligomerization reactor containing a zeolite catalyst and operating at a temperature, pressure and space velocity to crack, oligomerize and cyclize the olefins. In one aspect, methane in the effluent of the oligomerization reactor is recycled through the C2-5 thermal olefination reactor. Methods for the thermal olefination of methane are also disclosed.

Abstract: A system for steam cracking a whole crude that may include a volatilization device, a control system, a separator, and a steam pyrolysis reactor. The volatilization device may be configured to separate a vapor phase from a liquid phase. The control system may be configured to maintain a flow rate of the whole crude and steam, at an initial relative velocity of less than 30 m/s. The separator may be fluidly connected to the volatilization device and configured to separate the liquid phase into a second vapor phase, and a second liquid phase. The steam pyrolysis reactor may include a convection section and a steam pyrolysis heater section, the convection section configured to heat the vapor phase, the liquid phase, and the second vapor phase, and the steam pyrolysis heater section configured to steam crack hydrocarbons in the vapor phase thereby generating a cracked hydrocarbon product.

Abstract: Low sulfur fuel oil blend compositions and methods of making such blend compositions to increase the stability and compatibility of LSFO blends having paraffinic resids that are blended with distillates and/or cracked stocks of higher asphaltenes and/or aromatics content. In one or more embodiments, distillates and/or cracked stocks that incrementally reduce the initial aromaticity of the distillate or cracked stock with the highest aromaticity are sequentially blended prior to resid addition. Such incremental reduction and sequential blending have been found to provide a resulting low sulfur fuel oil blend that is both compatible and stable.
