Benefits of technology
The patent text describes a method and system for processing crude oil to remove sulfur compounds and form sulfur compounds. The method involves using microwaves to heat water, which is then used to separate the crude oil into gas, oil, and water phases. The heated water is then used to remove sulfur compounds from the crude oil. The system includes a crude oil processing unit and a microwave unit. The technical effect of this patent is to provide a cost-effective and efficient way to remove sulfur compounds from crude oil.
Problems solved by technology
Sulfur compounds are undesirable because of their odors and because sulfur compounds such as hydrogen sulfide are corrosive.
The corrosive nature of sulfur compounds contributes significantly to the costs of construction, operation and maintenance of a petroleum refinery.
Additionally, sulfur compounds may cause problems in gasoline engines and can contribute to environmental pollution.
Sulfur in crude oil can generate hydrogen sulfide and other sulfur containing gases during transportation and, consequently, increase the difficulty of such operations.
However, most of these technologies are based on conventional refining techniques and have a relatively high cost.
Furthermore, these technologies fail to sufficiently address the problem of removing sulfur and resulting formed sulfur compounds such as H2S.

Embodiment Construction
[0020]The present disclosure will now be described more fully with reference to the accompanying drawings, which illustrate embodiments of the disclosure. This disclosure may, however, be embodied in many different forms and should not be construed as limited to the illustrated embodiments. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0021]Embodiments of the disclosure include the use of microwave heating to promote the separation of components of crude oil, such as performed in a crude oil processing plant. In some embodiments, microwaves may be used to heat a crude oil stream to promote the separation of sulfur (for example, H2S) and light end components from the crude oil stream. In such embodiments, the microwaves may be used to provide interphase heating between the gas phase and the oil phase of the crude oil stream. In some embodiments, microwaves ma...

Embodiments of the disclosure include processes using microwave heating to promote the separation of components of crude oil. In some embodiments, microwave-heated water may be used to heat the interphase between the gas phase and the oil phase of a crude oil stream to promote the separation of sulfur (for example, H2S) and light end components of the crude oil stream. In some embodiments, microwave-heated water may be used to heat the interphase between the oil phase and the water phase of a crude oil stream to promote the separation of water, salt, or both of the crude oil stream. Systems having a microwave unit to provide microwave-heated water to crude oil stream are also provided.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from U.S. Provisional Application No. 62 / 355,683 filed Jun. 28, 2016, and titled “CRUDE QUALITY ENHANCEMENT BY SIMULTANEOUS CRUDE STABILIZATION, SWEETENING, AND DESALTING VIA MICROWAVE ASSISTED HEATING.” For purposes of United States patent practice, this application incorporates the contents of the Provisional Application by reference in its entirety.BACKGROUNDField of the Disclosure[0002]The present disclosure generally relates to the processing of crude oil. More specifically, embodiments of the disclosure relate to crude quality enhancement using microwaves.Description of the Related Art[0003]Elemental sulfur and sulfur compounds are naturally present in many petroleum crude oils. The amount of sulfur varies over a wide range; for example, crude oil from Texas contains about 0.1 weight percent sulfur, whereas crude oil from Saudi Arabia and Kuwait contains about 3 weight percent sulfur to 5 weight perc...
