Abstract: Described herein are methods of recovering lithium from dilute lithium sources. The methods include concentrating a dilute aqueous lithium source to yield an extraction feed having an extraction lithium concentration; extracting lithium from the extraction feed using direct lithium extraction in an extraction stage to yield a lithium intermediate; concentrating a stream obtained from the lithium intermediate in a concentration stage to yield a lithium concentrate; and converting lithium in the lithium concentrate to lithium hydroxide.

Abstract: A system for providing electrical power includes a high temperature heat source, an ambient temperature heat sink, an ORC generator, a solar thermal collector, and an SDES device. The ORC generator includes a generator working fluid with a boiling temperature greater than an ambient temperature of the ambient temperature heat sink, and the generator working fluid receives heat from the high temperature heat source and exhausts heat to the ambient temperature heat sink. The solar thermal collector is in thermal communication with the high temperature heat source to heat the high temperature heat source. The solar thermal collector includes a photovoltaic (PV) module, and the solar thermal collector is configured to convert a first portion of sunlight to thermal energy and a second portion of the sunlight to electrical energy. The SDES device receives electrical energy from one of the ORC generator and the PV module.

Abstract: A method can include receiving production fluid flow rate data from a well in a field that includes a plurality of wells; generating a gas lift profile for the well using the production fluid flow rate data; solving a system of equations representing at least two gas lift profiles for at least two of the plurality of wells to generate results; and issuing an instruction based at least in part on the results to control gas lift for production of fluid by the well.

Abstract: Systems and methods presented herein provide for a screw conveyor adsorption moving bed that separates carbon dioxide from a gas mixture. Adsorbent particles are transported between an adsorption section of the reactor, which can be an outer column, and a desorption section, which can be an inner column. The particle transport is facilitated by the screw conveyor located inside the inner column. The screw conveyor is specially designed to have a hollow screw, shaped as a spiral surface, attached to a central shaft. The screw surface is also equipped with plurality of holes and a flexible edge attachment to seal against the cylindrical surface. The hollow shape allows the gas to flow from the inlet of the shaft to the particles through the holes on the screw, thus creating uniform gas distribution.

Abstract: Methods include introducing a multistage treatment fluid into one or more intervals of a wellbore, wherein the treatment fluid contains one or more stages of a polymer-forming composition and one or more stages of a spacer fluid and initiating polymerization of the one or more stages of polymer-forming composition. Methods may include designing a multistage treatment fluid containing one or more stages of a polymer-forming composition and one or more stages of a spacer fluid, wherein or more stages of the polymer-forming composition comprises a thermosetting polymer; and pumping the multistage treatment fluid into a wellbore, wherein the pumping rate is determined by constructing a model based upon (a) the minimum pumping rate determined from the critical reaction temperature and the downhole temperature, (b) the fracture closing time, (c) the temperature within one or more fractures, and (d) the maximum pumping rate.

Abstract: Methods and systems are provided for controlling operational parameters of a CO2 compression surface facility or pipeline in order to maintain a CO2 stream having impurities flowing in the pipeline in a liquid or supercritical phase. Sensors may be provided to sense whether the flow is single-phase or two-phase flow, and feedback provided to adjust the pressure and/or temperature at the pipeline inlet. The system is preferably optimized to limit power consumption and/or cost.

Abstract: Methods and systems relate to a pressure exchanger which exchanges pressure energy from a high pressure clean fluid system to a relatively low pressure harsh fluid system for use in pressurizing the harsh fluid and directing the fluid to a wellbore as high pressure harsh fluid without the harsh fluid contacting identified portions of the pressure exchanger.

Abstract: Systems and methods presented herein provide for a box chain conveyor adsorption moving bed that separates carbon dioxide from a gas mixture. A box chain conveyor is oriented around a wall, including a chain that moves in a closed loop around the wall. One side of the box chain conveyor is in an adsorption section and an opposite second side is in a desorption section. Particle boxes contain adsorbent particles, and the chain moves the particle boxes around the wall in the closed loop. Heated gas passes through the desorption section, causing CO2 to desorb from particle boxes in the desorption section. Desorbed CO2 is expelled from an output.

Abstract: A technique for reducing harmonic vibration in a multiplex multi-pump system. The technique includes establishing a lower bound of system specific vibration-related information such as via pressure variation or other vibration indicator. Establishing the lower bound may be achieved through simulation with the system or through an initial sampling period of pump operation. During this time, random perturbations through a subset of the pumps may be utilized to disrupt timing or phase of the subset. Thus, system vibration may randomly increase or decrease upon each perturbation. Regardless, with a sufficient number of sampled perturbations, the lower bound may be established. Therefore, actual controlled system operations may proceed, again employing random perturbations until operation of the system close to the known lower bound is substantially attained.
