The key points of the technical solutions are as follows. An exhaust separation device is installed in a crankcase of an engine. An oil-gas separation technology is adopted to manufacture an oil-gas separator and a diffusion vortex chamber. According to an aerodynamic principle, the separation degree of the exhaust is improved through compression and high speed vortex in the energy saving device, in such a manner that engine oil vapor in the exhaust is separated from combustible mixed gases, and then sent to the engine via an air intake throttle. The present invention enables complete combustion of the fuel, so as to achieve effects of oil-saving and emission-reducing.

    Abstract: An engine crankcase breather for oil segregation, from blow-by gases, in an engine. The engine crankcase breather includes a housing with an inlet located in a downstream direction of the blow-by gases and an outlet. The breather also includes a baffle within the housing which poses a tortuous path for the blow-by gases, in order to segregate oil particles from the blow-by gases. The baffle includes a hook-shaped portion, in which the oil segregation takes place. The engine crankcase breather further includes a trough extending within the housing. The trough is aligned with the hook-shaped portion of the baffle, to collect the segregated oil from the blow-by gases.

  • Patent number: 8657919
    Abstract: High molecular weight (HMW) gases are separated from an exhaust gas of a combustion source using a blower and an interior vent within the exhaust stack. The interior vent includes a vent wall having a top portion attached to the interior surface of the exhaust stack along the entire inner perimeter of the exhaust stack and a lower portion that extends downward into the exhaust stack to form an annular space or gap between the vent wall and the interior surface of the exhaust stack, and at least one opening in the interior surface of the exhaust stack between the top and bottom portions of the vent wall. The blower creates a tangential flow of the exhaust gas with sufficient centrifugal force to concentrate substantially all of the HMW gases along the inner surface of the exhaust stack. A transfer pipe removes the HMW gases from the interior vent.

  • Publication number: 20140033922
    Abstract: A two stage gas-liquid separator assembly includes a housing having an inlet for receiving a gas-liquid stream and an outlet for discharging a gas stream. A first plenum chamber includes a pre-separator that causes liquid to separate from the gas-liquid stream and to drain to a lower portion of the first plenum chamber. A second plenum chamber includes a main separator downstream of the pre-separator that further causes liquid to separate from the gas-liquid stream and to drain to a lower portion of the second plenum chamber. A first drain port drains liquid from the lower portion of the first plenum chamber and a second drain port drains liquid from the lower portion of the second plenum chamber. Liquid drains from the first and second plenum chambers regardless of a pressure difference between a pressure in the first plenum chamber and a pressure in the second plenum chamber.

  • Publication number: 20140033921
    Abstract: A gas-liquid separator comprises a housing having an inlet for receiving a gas-liquid stream and an outlet for discharging a gas stream. An impactor nozzle structure is supported by the housing and situated downstream of the inlet. The impactor nozzle structure receives the gas-liquid stream and accelerates the gas-liquid stream through an orifice that extends through the impactor nozzle structure. An impaction surface is supported by the housing and situated downstream of the orifice. The impaction surface receives the accelerated gas-liquid stream and causes separation of liquid particles from the gas-liquid stream so as to produce the gas stream, and a baffle situated downstream of the impaction surface modifies a flow of the gas stream so as to reduce carryover of liquid particles in the gas stream. A shroud for an inertial impactor gas-liquid separator is disclosed. A method for separating liquid particles from a gas-liquid stream is disclosed.

  • Publication number: 20140024873
    Abstract: The present disclosure provides for processes including a coke catcher that may be emptied during normal operation or steam standby, thereby overcoming the deficiencies in the prior design as discussed above, the coke catchers and process flows disclosed herein protecting the secondary transfer line exchanger from foulant while not limiting the time between heater cold shutdowns. The designs consider the impact of decoking options, such as when decoking to a firebox as opposed to a decoking drum. Further, flow and cost considerations are addressed in various embodiments; for example, decoke valves are fairly expensive, and process flows disclosed herein may provide for relocation of the decoke valve to facilitate coke catcher operations while not adding an expensive valve to the overall operating flow scheme.

    Abstract: A particle separator comprises a pipeline that allows a fluid to flow in a curved direction of flow. The particle separator includes an inlet region, a curved deflection region, which in the direction of flow follows on from the inlet region, with an inside wall and an outside wall, and a delimitation body. The delimitation body at least in some sections extends between the inside wall and the outside wall in the interior of the deflection region and is curved in the same direction as the deflection region.
