  • Patent number: 10640965
    Abstract: The present invention relates to a manhole capable of an oil-water separation. An external air is introduced into a manhole through a inlet guide pipe and naturally and easily separate an oil-water mixture sewage into an oil sewage and the water sewage. The manhole may be installed in an area where the amount of the oil sewage and the water sewage is irregular, e.g., in an area single-family houses, multi-family houses, restaurants, roads, parking lots, gas stations are clustered. According to the present invention, an inlet guide pipe is provided in a manhole body and coupled to an inlet pipe. An oil-water mixture sewage flows in the manhole through the inlet guide pipe. The oil-water mixture sewage drops from the inlet guide pipe, causing turbulence or swirl. Due to the turbulence or swirl, the external air is also introduced through the inlet guide pipe and separates the oil-water mixture sewage into an oil sewage and a water sewage by a specific gravity difference.

  • Patent number: 8623221
    Abstract: A sand separator for capturing sand and rock debris from recovered natural gas fracturing fluid includes a cylindrical, high-pressure-rated vessel disposed vertically and immediately downstream of the gas wellhead. High pressure fracturing fluid enters the top of the separator into an inner flue extending coaxially downward to terminate a spaced distance above the bottom of the vessel. Transverse baffles spaced apart along the length of the flue extend through the flue to the inner walls of the vessel to keep the flue centered within the separator. As the fluid enters the separator, openings through the flue near the vessel inlet permit lighter weight and gaseous constituents to escape the fluid and bypass the flue, thereby reducing the velocity of the fluid remaining inside the flue. As the remaining fluid falls to the bottom of the vessel, it further slows as it reverses direction to rise between the flue and the vessel walls.

  • Patent number: 7297284
    Abstract: A separator provides improvements for better separation of an effluent into constituent parts and greater ease of use. A tapered basket provides improved flow and better filtration. A baffle directs effluent into the basket with greater force. An asymmetrical flange prevents mis-orientation the basket and baffle. An improved oil valve provides a locking mechanism to prevent dislodging of the valve during cleaning. An alternative valve uses a sensor to sense an oil/water interface and close the oil valve appropriately. A top seal prevents leakage of effluent at connection points with the lid of the housing. An underground unit allows below floor level installation of the separator. A bidirectional unit can be reversed to provide flow in either direction.
