The disclosure relates to the technical field of energy saving and consumption reduction, and in particular, to a gas-liquid recycling device. A gas-liquid recycling device and a method of using same provided by the disclosure includes a gas-collection hood, a gas delivery pipe and a liquid delivery pipe. A gas inlet port of the gas delivery pipe is connected to the gas collection hood, a gas outlet port of the gas delivery pipe is inserted into a liquid outlet port of the liquid delivery pipe, and a liquid inlet port is located at an end of the liquid delivery pipe opposite to the liquid outlet port.

A system may automatically control a pipeline heating system to maintain a desired temperature and/or to provide flow assurance of process fluid along a pipeline. The system may identify the occurrence and location of the solidification of a given process fluid or the melting of the given process fluid by monitoring temperatures along the pipeline and identifying from the monitored temperatures the occurrence and location of a latent heat signature associated with the solidification or melting of the given process fluid. The system may calculate and display fill percentages of the solidified process fluid at locations along the pipeline. The system may determine the percentage of a given section of pipeline that is filled with solid and/or liquid process fluid on a meter-by-meter basis. The system may perform automated re-melt operations to resolve plugs of solidified process fluid that may occur in the pipeline.

By monitoring pressure transients in a liquid within a liquid distribution system using only a single sensor, events such as the opening and closing of valves at specific fixtures are readily detected. The sensor, which can readily be coupled to a faucet bib, transmits an output signal to a computing device. Each such event can be identified by the device based by comparing characteristic features of the pressure transient waveform with previously observed characteristic features for events in the system. These characteristic features, which can include the varying pressure, derivative, and real Cepstrum of the pressure transient waveform, can be used to select a specific fixture where a valve open or close event has occurred. Flow to each fixture and leaks in the system can also be determined from the pressure transient signal. A second sensor disposed at a point disparate from the first sensor provides further event information.

Herein pipeline pressure, temperature and NGL constituents are manipulated for the transportation and optional storage in a pipeline system of natural gas mixtures or rich mixtures for delivery of chilled Products for downstream applications. Pressure reduction from a last compression section delivers internally chilled Products for reduced capital and operating costs. A high lift compressor station before the pipeline terminus provides pressure differential for Joule-Thompson chilling of the pipeline contents. The chilling step can be retrofitted to existing pipeline systems, and the chilling steep can include a turbo expander or the like for recovery of pipeline pressure energy for power generation. For like throughout, with this higher pressure operation, the effects of enhanced NGL content results in a reduction in diameter of the pipeline by at least one standard size. Substantial overall reduction in energy consumption and associated CO2 emissions is thereby achieved through integrated pipeline/processing applications.
