A method of installing a trench for containing a cryogenic spill, including the step of constructing multiple precast concrete sections at a first location, each section preferably having a bottom wall and spaced apart side walls connected to and extending up from the bottom wall. Each section preferably has end portions that enable connection to another said concrete section. The method includes applying a polymeric concrete material to the bottom wall and side walls of each concrete section preferably using a spray application. The concrete sections are connected together using connections that preferably join one end portion of a concrete section to and end portion of another concrete section. An epoxy grout or non-sag seal can be preferably applied to the connections.

A method of installing a trough or trench for containing a cryogenic spill, includes the step of constructing multiple precast concrete sections at a first location, each section having a bottom wall and spaced apart side walls connected to and extending up from the bottom wall. Each section has end portions that enable connection to another concrete section. The method includes (at the first location), preparing multiple panels of polymeric concrete material by filling one or more molds with a slurry or liquid polymeric concrete material and after time allowing the material to cure and harden. At the first location, one or more of the panels is adhered to the bottom wall and side walls of each concrete section using an adhesive. After adhering of the panels to the concrete sections, the concrete sections are transported from the first location to a second location that is remote from the first location. At the second location, the concrete sections are connected together using connections that join one end portion of a concrete section to and end portion of another concrete section. In one embodiment, the trough or trench is placed next to a pipe rack having cryogen containing flow lines. A slab and riser arrangement preferably channel any spill to the trough or trench.

Described embodiments include a system and a method. A described system includes a pipeline system. The pipeline system includes a transportation conduit containing a natural gas hydrate flowing from a first geographic location to a second geographic location. The pipeline system includes a cooling conduit running parallel to the transportation conduit, and having a heat-transfer surface thermally coupled with the flowing natural gas hydrate. The cooling conduit contains a heat-transfer fluid flowing between the first geographic location and the second geographic location. The flowing heat-transfer fluid has a target temperature range predicted to maintain a selected stability of the flowing natural gas hydrate.

The disclosed systems and methods are related to a positive displacement compression for use in various applications including gas processing, air conditioning, refrigeration, etc., to produce an isothermal compression to enhance the compression efficiency. The heat exchange enhanced compression is conducted by the use of cylinders partially filled with incompressible fluid (e.g., oil) acting as a piston compressing working fluid (e.g., CO.sub.2). The isothermal compression is contemplated in various modifications. A variety of heat exchange (cooling) techniques may be arranged either within the compression chamber or the compression process may be embedded in the heat exchanger to cool down the working fluid (for example, CO.sub.2).

A water management system is provided. The system includes a manifold with ports adapted to connect the manifold to piping that connects to various water fixtures in a home or building. Each port has a flow sensor and an actuated valve configured to shut off flow to a fixture in the event of a leak in order to mitigate damage from the leak. Water flow occurring due to a leak may be detected and mitigated based on input provided by the flow sensor and a motion sensor, a button switch, or a timer switch.

An arrangement comprising at least one liquefaction plant for liquefying a gaseous medium to produce a liquefied medium; and at least one storage tank for storing the liquefied medium. A first transfer line is provided which is connected between the liquefaction plant and the storage tank, for transferring liquefied medium from the liquefaction plant into the storage tank. A second transfer line is connected between the liquefaction plant and the storage tank, for transferring gaseous medium from the storage tank into the liquefaction plant. The second transfer line, which used for transferring medium from the storage tank into the liquefaction plant, is arranged so that it is routed at least partially through the area of the storage tank in which the liquefied medium is stored in use.
