  • Patent number: 10520250
    Abstract: A system and method for removing nitrogen and producing a high pressure methane product stream and an NGL product stream from natural gas feed streams where at least 90%, and preferably at least 95%, of the ethane in the feed stream is recovered in the NGL product stream. The system and method of the invention are particularly suitable for use with feed streams in excess of 5 MMSCFD and up to 300 MMSCFD and containing around 5% to 80% nitrogen. The system and method preferably combine use of strategic heat exchange between various process streams with a high pressure rectifier tower and the ability to divert all or a portion of a nitrogen rejection unit feed stream to optionally bypass a nitrogen fractionation column to reduce capital costs and operating expenses.

  • Patent number: 10505238
    Abstract: A cooling system includes a cooling fan that blows cooled air to a main battery and a temperature sensor. When the temperature of the main battery is equal to or higher than a first predetermined temperature after start up of an electric drive vehicle, the cooling fan is driven with a constant command value for a predetermined time period and detection process of abnormal condition is performed for detecting presence or absence of abnormal condition of the cooling fan based on an actual rotation speed of the cooling fan. When the start up of the electric drive vehicle is based on an external charging operation of the secondary battery, driving of the cooling fan with the constant command value is inhibited. This structure ensures sufficient opportunities for detecting presence or absence of abnormal condition of the cooling fan.

  • Patent number: 10384318
    Abstract: Modular thermal truss plates carry heat in multiple directions. Framing around an array of flat heat pipes provides mechanical and thermal connections to other truss plates, and a base, such as a satellite, thereby supporting thermally active equipment. Walls sandwich banks of flat heat pipes and may bond to a honey comb, metal core conducting heat between multiple walls. Each bank of flat heat pipes passes heat best in one direction, and may be formed of corrugated copper sheets spaced apart by a metal mesh, such as an expanded metal or screen, also stamped or otherwise formed into a corrugated configuration. Joining methods (e.g., brazing, soldering, etc.) increase stiffness, pressure containment, and strength, by binding the two layers of metal sheet to one another.
