Benefits of technology

The present invention provides a process for creating high-quality base oils from used lubricating oils and crude oils. This process involves solvent extraction, solvent or catalytic dewaxing, and hydrotreating. This process enables refineries to efficiently convert and produce Group III and Group II base oils, while also maintaining the ability to make heavier base oils, waxes, and bright stocks. Overall, this process allows for more efficient use of used oil and reduces waste.

Problems solved by technology

The existing solvent extraction, solvent de-asphalting, dewaxing, and hydrofinishing technologies which make Group I base oils from crude oils cannot make Group II and III base oils from crude oils.

Embodiment Construction

[0052]Refer now to the drawings wherein depicted elements are, for the sake of clarity, not necessarily shown to scale and wherein like or similar elements are designated by the same reference numeral through the several views. In the interest of conciseness, well-known elements may be illustrated in schematic or block diagram form in order not to obscure the present invention in unnecessary detail, and details concerning various other components known to the art, such as solvent extraction extraction units, hydrotreaters, and the like necessary for the operation of many oil and gas processes, have not been shown or discussed in detail inasmuch as such details are not considered necessary to obtain a complete understanding of the present invention, and are considered to be within the skills of persons of ordinary skill in the relevant art. Additionally, as used herein, the term “substantially” is to be construed as a term of approximation.

Abstract

A process for creating higher quality and lower quality base oils from used lubricating oils and crude oils, wherein the higher quality base oils may be either Group III or Group II and the lower quality base oils may be either Group II or Group I. Vacuum gas oils produced from used lubricating oils and from crude oils are processed via two or more process steps, including solvent extraction, solvent or catalytic or iso dewaxing, and hydrotreating. Such process enables efficient conversion and operation of refineries formerly capable only of making Group I base oils, even as their ability to make heavier base oils, waxes, and bright stocks is preserved, substantially to the same extent as such products had been made prior to undertaking the conversion.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 532,935, filed Jul. 14, 2017, which application is hereby incorporated herein by reference, in its entirety.TECHNICAL FIELD[0002]The invention relates generally to base oils and, more particularly, to a process for producing high quality and low quality base oils from used lubricating oils and crude oils.BACKGROUND[0003]Over the course of many years, the vast majority of equipment and machinery (including engines of automobiles and trucks) have been substantially improved, thereby achieving dramatic increases in performance. In the case of internal combustion engines for automobiles using Passenger Car Motor Oils (“PCMOs”) and trucks using Heavy Duty Engine Oils (“HDEOs”), performance improvements have been achieved in higher fuel economy and lower emissions. This increased performance has, in turn, created increased requirements for higher performing finished lubr...
