Many processes operations require the removal of entrained non-gas particles from multi-phase gas streams. The removal of these non-gas particles is the process in itself (capture of a valuable product) or the process of cleaning a gas stream in order to protect either stationary or rotating equipment from the harmful effects due to non-gas particles entering those devices. Liquid non-gas particles can be generated from a pure gas due to a gas-liquid phase change occurring within a state change of the gas. Also the source of liquid particles can be a liquid phase (crude oil, water) in multi-phase stream from gas or oil well. Solid phase, black powder, is a materials that collects in gas pipe line from: water, liquid hydrocarbons, salts, sands or dirts. The removal of entrained non-gas particles from a multi-phase gas stream is a separation process. Mechanical separation utilize particle motion in field of centrifugal acceleration. The existing separators have a lot of advantages but also a lot of disadvantages. In this article author present a new ethical solution which, in our opinion, has some advantages in comparation with the existing solutions. The new technical solution (Figure 6.) formed based on the following requests: • The separator to be used for the treatment of the three phase mixtures; • The separator should be part of the facility for the continual separation process and the transport of clean gas and water. Upon realizing these request, a prototype was formed consisting of the following sections: charging device, rotor separator with an insert consisting of conical discs, clean water transport pump, compressor, drive with frequent velocity regulator and power gear, ancillaries system and measuring equipment. In the field of centrifugal accelaration the mixture, solid-liquid-gas, is separated down to its basic components. The solid fraction and water (sludge) gets caught on the largest diameter of the rotor, goes through the impeller is transported to the desired place. The easiest fraction (gas) gets caught at the place closest to the rotation axis and is directed to the compressor. The new technical solution, that we are hereby presenting, when compared to the existing solutions has the following advantages: • The possibility of continual transport of the separation products, becomes acceptable to a great number of users; • The separators in general have the possibility of achieving high level of accelaration (500÷300.000g), which makes it acceptable for fine and ultra-fine separations. • The facilities with these separators are of smaller dimensions, simpler construction, which directly influences the amount of investments. By analysing data, acquired by prototype testing, the possibilites of realizing significant savings have been noticed. It should be expected that by reducing the quantity of the solid and liquids in the gas, the quality of the final product will be improved. The final result would be an improved technical solution that would be transferred to an industrial facility with a wide range of possibilities.
