Sand separation systems and methods according to which one or more energy sensors are adapted to detect a response to energy imparted to a sand separator of a known type. One or more computers are adapted to communicate with the one or more energy sensors. The one or more computers and/or the one or more energy sensors are pre-tuned. The one or more computers are configured to determine the unknown sand level in the sand separator of the known type based on: the response detected by the one or more energy sensors, and the pre-tuning of the one or more energy sensors and/or the one or more computers.

A cyclone type liquid/gas or liquid/liquid separator having separation properties that are stabilized, even when the flow rate and the proportions of the liquid phases for separation vary, by means of a platform situated in the low portion of a cylindrical separation chamber that is fed at its top end via a tangential feed orifice. An installation and a method are also provided for separating the oil and water contained in crude oil, with the help of a cyclone separator.

A device for separating and extracting suspended solids and particles from a fluid is shown. The device can include a hydro-cyclonic process unit, a variable geometry vortex process unit, a reverse coalescence and flocculation process unit and a fixed geometry vortices separator process unit. The fluid to be treated can enter the device through a fluid inlet and travel and recirculate through the several process units. The process units can collectively induce vorticose separation of the fluid and separate suspended solids and particles within the fluid. The suspended solids and particles can then be extracted from the device via one or more extraction fluid outlets. After the desired amount of suspended solids and particles has been removed, the processed fluid can be discharged from the device.

The invention in at least one embodiment includes a system for treating water having an intake module, a vortex module, a disk-pack module, and a motor module. In a further embodiment, a housing is provided over at least the intake module and the vortex module and sits above the disk-pack module. In at least one further embodiment, the disk-pack module includes a disk-pack turbine having a plurality of disks having at least one waveform present on at least one of the disks.

An apparatus for the extraction of phosphorus from wastewater that includes a precipitation module and a retention module. The precipitation module includes a crystallization vessel, one or more inlets disposed in a lower region of the precipitation module and at least one outlet disposed in an upper region of the precipitation module. The retention module includes a sedimentation vessel, at least one inlet disposed in an upper region of the retention module and at least one outlet disposed in a lower region of the retention module. At least one outlet of the precipitation module is connected to at least one inlet of the retention module and at least one outlet of the retention module is connected to at least one inlet of the precipitation module. The volume VS of the sedimentation vessel is greater than/equal to 0.6 times the volume VC of the crystallization vessel (VS≧0.6.Math.VC).

An automated sand separator discharge system includes a sand separator disposed downstream of a wellhead, an inlet conduit for transporting a process stream to the sand separator, a fluid outlet conduit for transporting a liquid and gas stream from the sand separator, a sand discharge conduit for removing sand from the sand separator, first, second, and third valves disposed along the sand discharge conduit, a first transducer connected between the first and second valves and operative to measure pressure in a portion of the sand discharge conduit and to produce a pressure reading, and a control panel operatively connected to the first, second, and third valves and the first transducer, the control panel being programmed to initiate and terminate discharge of sand from the sand separator, and to determine if the first and second valves are sealing completely when closed.

A dirt separator including a vessel having a separation container having a lateral container wall, a container bottom, and a container axis, which container has an inlet and an outlet as well as an interior, and having a particle separation chamber, which is disposed at the outlet of the separation container and stands in a fluid connection with the separation container, an inlet for supply of liquid into the vessel, and an outlet for discharge of the liquid out of the vessel. The dirt separator is configured in such a manner that liquid introduced into the separation container flows downward along the container wall in a cyclone-like movement, and then flows upward to the particle separation chamber within the liquid that flows downward in cyclone-like manner, and the dirt separator includes at least one particle separator, which is disposed in the particle separation chamber.

A method comprises controlling an operating pressure of a fluid from a borehole. The fluid comprises solids and entrained gas. The method further comprises removing at least a portion of the entrained gas from the fluid at an upstream location. The method further comprises removing residual entrained gas from the fluid at a downstream location. The method further comprises separating at least a portion of the solids from the fluid. The method further comprises circulating the separated fluid back to the borehole. Separating of solids occurs after the removing of entrained gases from the fluid at the downstream location.

A hydrocyclone vibration measurement system includes an upper vibration sensor attached to the overflow of a hydrocyclone and a lower vibration sensor attached to the underflow of the hydrocyclone. A vibration analysis system includes an ADC, an overall vibration value processing channel, and one or more band pass filters. The overall vibration value processing channel generates overflow and underflow scalar vibration values representing overall vibration measured at the overflow and underflow portions of the hydrocyclone. The vibration analysis system may interface with a DCS to provide control information for controlling the hydrocyclone based on the overflow and underflow scalar vibration values.
