Abstract: A method of operating a heat transfer system includes circulating a heat transfer fluid through a heat transfer circuit in fluid communication with an electric system, and obtaining real-time measurements of fluid properties of the heat transfer fluid. A dimensional effectiveness factor for the heat transfer fluid (DEFfluid) is calculated based on the fluid properties and for a selected pump and a selected dominant flow regime within the heat transfer circuit, and a dimensional effectiveness factor for a reference fluid (DEFreference) is calculated for the selected pump and the selected dominant flow regime within the heat transfer circuit. A normalized effectiveness factor (NEFfluid) of the heat transfer fluid is then obtained, whereby a health of the heat transfer fluid is obtained. If the NEFfluid is below a predetermined threshold, the health will be considered deteriorated, and if the NEFfluid is above the predetermined threshold, the health will be considered viable.

Abstract: A method for identifying in situ presence of a hydrocarbon reservoir or of a pipeline leakage is disclosed. The method can include obtaining a sample from an area of interest, such as a sediment sample or water column sample near a hydrocarbon seep or near an offshore pipeline; analyzing the sample to detect nucleic acid, protein or metabolite signatures that are indicative of cold-shock response; identifying the relative abundance of the cold-shock signatures present in the sample in comparison to the surrounding environment.

Abstract: The present disclosure relates to processes for producing hydrocarbon fuels from lignocellulosic biomass. A process may include introducing biomass to a pretreatment system, and a first separation system forming a pentose-rich stream and a pentose-lean stream. The pentose-lean stream may be introduced to a hydrolysis system forming a hydrolysate and the hydrolysate introduced to a second separation system forming a hexose-rich stream and a lignin stream. Additionally, at least one of the pentose-rich stream or the hexose-rich stream may be introduced to a bioreactor containing microorganisms configured to produce hydrocarbon fuels. Additionally, the present disclosure also relates to systems for the production of hydrocarbon fuels. A system may include a pretreatment system, a first separation system, a hydrolysis system, a second separation system, and one or more bioreactors. Alternatively a system may include a pretreatment system, a hydrolysis system, a sugar separation system, and one or more bioreactors.

Abstract: A method for separating classes of hydrocarbon compounds from a feed stream including a hydrocarbon mixture is disclosed. The method includes the steps of passing a feed stream through a plurality of separation units arranged in a series in any order, wherein each separation unit has an adsorbent material; and separating classes of hydrocarbon compounds from the feed stream. When one of the plurality of separation units comprises an adsorbent material that is a metal organic framework selected from a zirconium, hafnium, cerium, or titanium-based metal organic framework, then another plurality of separation units includes an adsorption material that is different from the metal organic framework. The method is conducted in a liquid phase. The method can also use a single separation unit with a continuous cyclic bed apparatus. The method can be combined with refining and downstream processes.

Abstract: Systems and methods are provided for hydroprocessing of bio-derived feeds, such as bio-oils and/or other types of feeds including triglycerides, fatty acids, and/or fatty acid derivatives. The systems and methods can assist with maintaining a desired temperature profile within a reactor while performing hydroprocessing on a feed with substantial oxygen content. In various aspects, the initial bed of the reactor can be exposed to 30 vol % or less of the total fresh feed. The remaining portions of the fresh feed can be introduced below one or more of the catalyst beds in the reactor. By reducing or minimizing the amount of fresh feed introduced upstream from the initial catalyst bed that contains a catalyst with hydrodeoxygenation activity, the net amount of product recycle can be reduced or minimized while still maintaining a target temperature profile across individual catalyst beds and/or across the reactor.
