engineering for gas processing
3S Technology for gas separation was developed in 1997, with worldwide patents and successful field testing. It introduces advanced solutions for processing natural or associated gas in the oil and gas industry.
3S Technology is based on pre-swirled gas flow expansion in a Laval nozzle. At that point, due to the conversion of a portion of the gas flow’s potential energy into actual kinetic energy during its acceleration to supersonic speed, a rapid static pressure drop takes place in the flow, accompanied by its rapid cooling.
3S Technology regulates the flow temperature in the nozzle by means of a calculated selection of nozzle geometry and pressure drop rate (usually characterized by the Mach number « M »). The Mach number is selected in such a way that “targets” gas mixture components (i.e. components to be separated) transfer to a liquid phase. The droplets thus formed actively coagulate, assisted by the turbulent nature of the swirling flow. The flow swirling degree is usually selected so as to provide centrifugal forces in the nozzle working section at the level of about 100 thousand and higher.
Under the influence of centrifugal forces, the liquid droplets are moved into the boundary layer, where the gas-liquid mixture enriched with “target” components is formed. At this stage, the “central” portion of the flow is cleared from the “target” components.
Further on in the selection device, the gas flow is divided into two parts: gas-liquid flow directed into the gas-liquid separator and the flow of prepared (sales) gas directed to the consumer.
The use of diffusers at the outlet of the 3S-separator working part allows for converting some of the kinetic energy into potential energy due to deceleration. This results in substantially greater gas pressure at the outlet of the diffuser than the static pressure of a gas in a Laval nozzle, which is where the condensation of the target components occurs.
