Abstract: Provided are methods and systems for delivering a treatment fluid to a wellsite. An example method includes receiving a container containing a treatment fluid component from a treatment fluid component supplier. The method further includes introducing the treatment fluid component into a wellbore from the container by pumping the treatment fluid component out of the container and into the wellbore. The treatment fluid component is not transferred to another container during the receiving or the introducing.

Abstract: A method includes monitoring work done by a piece of equipment to generate backward-looking usage data. The method includes making a prediction of future work to be done by the piece of equipment, generating forward-looking usage data based on the prediction of future work, and making a prediction of when the piece of equipment is expected to fail based on the backward-looking usage data and on the forward-looking usage data. The method includes operating the piece of equipment after performing the prediction, and removing the piece of equipment from service prior to when the piece of equipment is expected to fail based on the prediction.

Abstract: A flow exchanger (FE) system comprising: a supplement pump receiving a supplement first fluid stream and outputting a pressurized supplement first fluid stream; a flow splitter comprising a flow restrictor, wherein the flow splitter receives the pressurized supplement first fluid stream and outputs a power stream and a treatment stream; a main flow manifold, wherein the treatment stream enters the main flow manifold subsequent to passing through the flow restrictor; and an FE cylinder filled downstream with a second fluid and having a fluid interface separator (FIS), wherein the power stream enters the FE cylinder upstream; wherein the power stream engages and pushes FIS downstream, thereby providing for a second fluid stream entering the main flow manifold; wherein a second fluid stream VFR=a power stream VFR; and wherein the main flow manifold provides for a manifold output fluid stream VFR=a pressurized supplement first fluid stream VFR.

Abstract: A hose assembly for a pump comprising a pressurized hose, wherein the pressurized hose is exposed to pressure during at least a part of the operation of the pump, and a leak detection system comprising an outer hose concentrically positioned about at least a portion of the pressurized hose such that an annular chamber exists between the pressurized hose and the outer hose, whereby a leak of the pressurized hose can be detected by monitoring the hose assembly and/or a leak sensor associated therewith.

Abstract: The present application thus describes a solar-thermal power generation plant that includes one or more towers; a plurality of heliostats disposed around each of the one or more towers; a direct solar evaporator mounted at an elevated position on each of the one or more towers, the heliostats being configured to reflect solar radiation toward the direct solar evaporator such that concentrated solar radiation heats a receiving surface on the direct solar evaporator; and a heat engine mounted at an elevated position on each of the one or more towers, attached to the direct solar evaporator, and configured to use the heat from the receiving surface on the direct solar evaporator to generate electricity.

Abstract: An inlet assembly for introducing a sample into a carrier gas stream for gas chromatography is disclosed including a housing having a bore that receives a liner. A sealing member having a core with a surface layer is positioned within the bore in sealing engagement with the bore and the liner. The surface layer of the sealing member has a lower adhesion to the housing than the core. The surface layer facilitates removal of the sealing member and the liner from the bore. A method of replacing an existing liner in an inlet assembly for chromatography is also disclosed. The method includes providing a liner with a sealing member having a core with a surface layer having a lower adhesion to the housing than the core, removing the existing liner from the bore and inserting a new liner with a new sealing member into the bore.
