A method of constructing a coil wound heat exchange module and transporting and installing the coil wound heat exchange module at a plant site, such as an natural gas liquefaction plant. A module frame is constructed and attached to a heat exchanger shell prior to telescoping of a coil wound mandrel into the shell. The module frame includes a lug and two saddles that remain attached to the shell throughout the process and when the heat exchanger is operated. The lug and saddles are constructed and located to stabilize the shell during construction, telescoping and transport (when in a horizontal orientation), and when the shell is installed at the plant site (in a vertical orientation). The lugs and saddles are adapted to allow for thermal expansion and contraction of the shell when it is transitioned from ambient to operating temperature and vice versa.

One aspect of the invention relates to a hydrocarbons fluid liquefaction system, having a first heat-exchange module having a pre-cooling exchanger having a pre-cooling circuit and a plurality of pre-cooling refrigerant circuits for pre-cooling the feed stream through the circulation of an expanded first mixed-refrigerant stream, and a second heat-exchange module having a liquefaction exchanger having a liquefaction circuit and a liquefaction refrigerant circuit for liquefying the feed stream through the circulation of an expanded second mixed-refrigerant stream, wherein each heat-exchange module has thermally insulating walls and a framework that allows the module to be transported and secured, and allows the first heat-exchange module to be stacked on top of the second heat-exchange module.

A modular gas turbine system is disclosed. The system includes a base plate and a gas turbine engine mounted on the base plate.

The system comprises a natural gas feed and a natural gas liquefaction facility having a refrigeration circuit comprising: a compressor adapted to compress at least one refrigerant fluid; a driver adapted to drive the compressor; and a heat exchanger adapted to receive a flow of natural gas from the natural gas feed and remove heat therefrom by heat exchange against the refrigerant fluid. A heat pump collects low-temperature thermal energy rejected from the natural gas liquefaction facility and transfers the collected thermal energy to a thermal energy storage system at a higher temperature. The system further comprises a processing facility powered by thermal energy from the thermal energy storage system.
