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.

A method of extraction of a liquid hydrocarbon fraction from carbonaceous waste feedstock. Waste material is slurried, by grinding or comminution of same into a substantially uniform stream of around waste material. Fluid would be added as required to supplement the ground waste to yield a slurry of desirable parametersthe fluid used would be primarily liquid effluent fraction recovered from previous operation of the method. Feedstock slurry is placed into a pressurized heat transfer reactor where it is maintained at temperature and pressure for a predetermined period of time. On discharge from the heat transfer reactor the processed emulsion is separated into liquid hydrocarbon fraction, liquid effluent fraction and solid waste fraction. A novel heat transfer reactor design is also disclosed.

The present invention provides a multiphase separator for separating a multiphase fluid produced by one or more oil wells, the multiphase separator comprising: a separating vessel, comprising an inlet chamber and an oil chamber for collecting oil at least partially separated by a barrier; an inlet for introducing the multiphase fluid into the separating vessel; wherein the oil chamber is positioned on the opposite side of the barrier to the inlet; a gas outlet configured to collect gas separated from the multiphase fluid; an oil outlet configured to collect oil, separated from the multiphase fluid, from the oil chamber; a water outlet configured to collect water separated from the multiphase fluid; and a gas and water mixture injector configured to inject a mixture of pressurized gas and water in a lower portion of the separating vessel.

The present invention relates to an apparatus for separation of high volume flows of mixtures provided with at least two immiscible phases, especially for the first separation steps of flows of water/oil/gas/sand mixture that enter the apparatus as a wellstream mixture. The invention also relates to a method for separation of high volume flows of mixtures provided with at least immiscible phases.

A container-type apparatus for wastewater treatment with a suspended particle system, including one or multiple biological reaction zones. The biological reaction zones can be facultative, anaerobic, anoxic, and aerobic and at least one of the biological reaction zones is a suspended particle system. Particles in the suspended particle system act as the carrier of microbiota and offer better conditions for them to grow. The apparatus adopts a box structure, such as a container type, which is convenient to move, flexible to assemble, and can be used multiple times. Based on actual requirements, this apparatus can also be a structure type. The suspended particle system can increase the concentration of microorganisms significantly, improve the ability to bear impact load, produce less sludge, and without sludge expansion.

A tank for removing sand entrained in a flow includes an inlet assembly including churn tubes configured to receive fluid provided into the tank such that sand is separated from water, gas and oil present in the flow. An oil outlet port communicates with an oil collection device, and a water outlet port communicates with a water outlet assembly.

The system and method for processing flowback fluid include a plurality of wellheads producing flowback fluid flows, a plurality of first stage separators corresponding to at least one wellhead of an installation with multiple wellheads and multiple flowback fluid flows, a plurality of metering devices corresponding to each first stage separator, and a second stage separator in fluid connection with the metering devices and the first stage separators. Flowback fluid flows pass from the wellhead to the first stage separators for initial separation of a gas phase, through the metering devices for determination of production levels for each wellhead, and into the second stage separator for an additional gas phase separation. The storage volumes of the first and second stage separators control the retention time in the second stage separator for safe and efficient operation.

The system and method for processing flowback fluid include a plurality of wellheads producing flowback fluid flows, a plurality of first stage separators corresponding to at least one wellhead of an installation with multiple wellheads and multiple flowback fluid flows, a plurality of metering devices corresponding to each first stage separator, and a second stage separator in fluid connection with the metering devices and the first stage separators. The second stage separator includes a solids separator to further control the storage volumes of the first and second stage separators and retention time in the second stage separator by removing solids.

An electro-separation apparatus for separation of drilling fluids is provided. The apparatus can include a reaction chamber and a set of electrode plates provided in the reaction chamber. A sediment outlet can be provided near a bottom of the reaction chamber and wiper blades can be provided for sweeping sediment that has collected on the electrode plates towards the sediment outlet.

The present disclosure provides a sedimentation tank capable of automatically adjusting liquid level and flow, which comprises one or more sedimentation cells which are connected in sequence, a water inlet pipe is arranged on the left side of the leftmost sedimentation cell; the front end of the water inlet pipe is bent and the input port of it is close to the wall; the highest point of the connecting pipe is lower than the highest point of the grease discharge port of the corresponding sedimentation cell, when the liquid level in the sedimentation cell reaches the discharge level of the connecting pipe, the connecting pipe automatically adjusts the flow according to different discharge level so as to adjust the liquid level of the sedimentation cell, and the settled sewage is discharged out of the tank or discharged into the next-stage sedimentation cell until the last stage, and finally discharged. The sedimentation tank has a compact and attractive structure and high space utilization, and different connecting pipe structures can be selected specifically, so as to change the capacity of adjusting the liquid level and flow of the sedimentation tank, and the sewage separation effect is thorough.
