Description

Technical Field

[0001] The present application relates to the technical field of engines, and in particular to a device for recycling engine power margin. Background Art

[0002] At present, natural gas wells are produced by exporting gas through their own pressure in the early stage of exploitation. As the pressure and output of the gas wells continue to decline, natural gas compressors are needed to reduce the wellhead pressure and increase production in the middle and late stages of exploitation. At the same time, the compressor outlet must reach the external pipeline pressure to ensure that the extracted natural gas can be exported.

[0003] Gas field developers typically install natural gas compressor units at wellheads or platforms (multiple wells). In many cases, these units are powered by natural gas engines. When selecting natural gas engines, a power margin is typically considered. In cold northern climates, the compressor unit's internal separators and sewage pipes require electric heat tracing and insulation. The separators and pipes installed at the wellhead or platform also require electric heat tracing and insulation. Depending on the unit model, this requires a power supply of approximately 3 kW to 10 kW. In summer, the compressors also require air coolers for cooling. Typically, a small natural gas generator set is installed on-site to provide the necessary power for the electric heat tracing and insulation components. In practice, the selected generator set power is typically no less than 30 kW to ensure 24 / 7 continuous operation, limiting the availability of lower-power engines. Many generator set manufacturers typically use high-power engines with low power ratings. This practice results in low generator set efficiency, high energy consumption, and a high investment, as well as increased difficulty in on-site equipment management.

[0004] With respect to the above-mentioned related technologies, the applicant believes that there is a lack of a device that has low energy consumption and can supply the necessary energy required by the generator and the air cooler. Utility Model Content
