Abstract: This disclosure presents a clean burning flare stack, or gas flare. The gas flare is air assisted to ensure clean burning. The disclosed gas flare provides smokeless clean burning of released gases. For example, the gas flare burns the released gases in a lean burning condition such that sufficient air is supplied to the surges of gases. In addition, the gas flare, by using a low pressure blower mixing chamber, is capable of handling low pressure gases and high pressure gases. As such, different flow rates may be provided to the gas flare when different amounts of low pressure and high pressure flammable gases are mixed with sufficient blower air to provide a clean burning condition. The disclosed smokeless gas flare is thus environmentally friendly and aesthetically appealing.

Abstract: A separation tank for the separation of a mixture of oil, gas, water, and solids obtained from an oil field includes distinct regions vertically located within the tank interior where constituent components of the mixture can collect. The inflowing mixture may be directed to a vertical column extending inside the separation tank and can be introduced to the tank interior through a swirl vane diffuser configured to impart a helical direction to the inflowing mixture that assist separation of the mixture component. To further facilitate separation of oil from the mixture, the separation tank may be operatively associated with an aeration system configured to generate and introduce an aerated liquid to the tank interior. Gas dissolved in the aerated liquid may form microbubbles that can naturally adhere to the oil and solids separate it from the mixture which can improve the quality of the water.

Abstract: A collection and concentration system including a separation tank having a plurality of distribution arms configured to separate and recover oil, water, and sediment or sand from an inflowing mixture of the same. The distribution arms are connected to and in fluid communication with a downcomer section of a center column that is vertically arranged in the separation tank. The distribution arms extend radially toward a sidewall of the tank and include tangential discharge nozzles that are tangentially directed toward the sidewall. Inflowing mixture directed tangentially against the sidewall is directed in a downward, helical manner that assists in the separation and recovery of oil, water, and sediment from the inflowing mixture.

Abstract: A separation tank having an interior space for separating gas and water from oil. A column is disposed in the interior space that has a top portion and a bottom portion, the top portion fluidly connected to an inlet, and the bottom portion fluidly connected to an outlet. The top portion of the column is open to the interior space of the tank through a spiral diffuser which includes a plurality of spiral vanes. An oil collector weir is located in the interior space and is fluidly connected to an oil outlet disposed external to the tank. An upper flow diverting baffle is located below the spiral diffuser and a lower flow diverting baffle is provided below the upper flow diverting baffle so that fluid flows from the spiral diffuser downwardly around the two flow diverting baffles. An aerated water dispensing system is associated with the tank and provides microbubbles to the interior space from the lower flow diverting baffle.

Abstract: A de-sanding tank with a conical bottom. The de-sanding tank includes an enclosed tank having a vertical wall that extends down to a flat bottom. A conical bottom is disposed within an interior of the tank. The conical bottom is secured to the vertical wall forming an enclosing space bounded by a wall of the conical bottom and the vertical wall and flat bottom of the tank. A solids outlet is disposed at a lower tip of the conical bottom configured for removal of solids. The conical bottom is supported by a foam structure located within the enclosing space.

Abstract: An automatically skimmable tank for removing oil from water. A water inlet with a 90 degree elbow that is turned sideways and points slight upward causes flow to first impinge on the wall of the tank then flow upward helically around the tank's internal diameter (ID) to maximize retention time so that oil separates from the water. At the tank's upper fluid level, the water flows to the center of the tank, then spirals downward to the bottom and under the incoming fluid flow before exiting via the water outlet. Oil is removed from the tank via an upwardly extending oil outlet riser provided with two horizontal anti-vortex plates. A level transmitter senses the oil-gas and the oil-water interfaces and a programmed PLC activates an oil valve and a low shear oil transfer pump to remove oil from the tank when the oil layer surrounds the anti-vortex plates.

Abstract: A de-sanding tank with a vertical exterior wall and an interior conical bottom with a solids outlet located at a lower tip of the conical bottom. Downwardly and tangentially oriented water jet nozzles within the tank cause a swirling action to remove solids. An enclosing space located between the vertical wall and the conical bottom has a honey-combed structure of closed pore foam as reinforcement for the conical bottom. Compartments within the honey-combed structure fill with water as the vessel is placed in service to add support for the conical bottom. Water enters the compartments via downwardly facing bottom openings that fill a common void located at the bottom of the enclosing space and then into the compartments. Weep holes provided between the top of each compartment and the interior of the tank allow the air from the compartments to enter the tank as the compartments fill.

Abstract: A self contained, trailer mounted condensation collection system for an oil and gas well. The system has a condenser for cooling and condensing those oil well gases that can be condensed and a separator for separating the condensed portion from the non-condensable portion of the gas stream so that the condensed gases can be recovered as liquid hydrocarbons. The system is powered by the gas pressure from the well and operates without any outside utilities so that it can be used at new well sites where infrastructure has not been built to support the well.

Abstract: Apparatus and method for reducing odor from a toilet bowl having an air cushion bladder seat with an orifice for passing air out of and into the bladder as a person sits down and rises from the air cushion bladder seat which is coupled to operate a switching valve. The switching valve has a first tube that connects the area above the water in the bowl to a second tube coupled to a gas/vapor moving means and disconnects a third tube that connects the toilet trap from the second tube as a person sits down on the air cushion bladder seat. The gas/vapor moving means is coupled to the second tube which to feed the gas/vapor to a fuel/air mixer of a combustion chamber for burning the gas/vapor with the fuel.
