    摘要: A system for growing algae includes a gas concentrator configured to receive a first gas containing CO2 at a first concentration and discharge a second gas containing CO2 at a second concentration higher than the first concentration, and a photobioreactor containing algae in an algae slurry and fluidically coupled to the gas concentrator to receive the second gas. A recycling line extends from a gas outlet on the photobioreactor to remove a third gas from the photobioreactor for future use in the photobioreactor.

    摘要: Systems and methods are provided for conversion of oxygenate feeds to distillate boiling range products using multiple moving bed reactor stages. The systems and methods allow for multiple stages to be used while avoiding the need for distillation or other boiling point based separation as the mixture of feed and effluent is passed between stages. Instead, a stripping gas is used to disengage the feed and effluent from the catalyst solids. In combination with an improved moving bed reactor design, this can allow substantially all of the feed and effluent from a first moving bed reactor stage to be passed into a second moving bed reactor stage, even when the feed and effluent include both vapor and liquid phase portions.

    摘要: An electric submersible pump (ESP) system is described herein. The ESP system includes a pump and a motor connected to drive the pump. The pump and motor are disposed to pump fluid into production tubing in a wellbore. The motor produces heat when operating. The wellbore contains wellbore fluids. A seal unit is connected between the motor and the pump. The seal unit contains oil to lubricate the motor. Further, the seal unit receives heat from the motor when the motor is running. The seal unit contains a structure to reduce loss of heat after the motor stops running to reduce an exchange of oil from the seal unit to the wellbore and to reduce an exchange of wellbore fluids from the wellbore to the seal unit.

    摘要: Systems and processes for collecting and transporting a fluid sample. In one embodiment, the system can include at least one apparatus that can include a rotatable shaft, one or more other moving parts, and at least one fluid path containing a lubricating fluid. The system can also include at least one sample container and at least one unmanned aerial vehicle configured to transport the at least one sample container. The system can also include at least one valve that can be configured to open and discharge a sample of the lubricating fluid from the at least one fluid path into the at least one sample container. At least one unmanned aerial vehicle station can be configured to receive the at least one unmanned aerial vehicle. At least one retention and loading mechanism can be configured to move the at least one sample container.
