254 results about "Sand separator" patented technology

A sand separator is a device that separates sand or other solids from water. One version of sand separator utilizes centrifugal force to separate sand or other heavy particles out of the water. The separated material drops down into a tank or reservoir where it can be removed later or in the case of in-well separators, the separated sand drops into the bottom of the well. It is not a true filter, since there is no physical barrier to separate out the particles, but it is often used upstream of a filter to first remove the bulk of the contaminant, where the filter does the final cleaning. This type of design reduces the time required to flush and clean the filter.

Sand separator for petroleum and natural gas wells

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. At the bottom of the vessel, sand and rock debris precipitates out of the slowed fluid and accumulates above a clean-out valve by which the debris periodically may be removed. The gas and fluid recombine relatively free of sand and rock debris and exit the vessel at one or more outlet ports through the vessel walls. The sand separator functions in both exploration and production wells for both petroleum and natural gas.
