Condensed rotational separation

Condensed Rotational Separation is based on partial condensation of components of gas-gas mixtures. Condensation is induced by flash evaporation or pressure distillation. The rotational particle separator removes the micron sized particles formed by condensation from the gas. Yields and purities are enhanced by adding a next stage of liquid flash and relooping the gas to the first stage. A great improvement in separation performance, in both yields and purities, is achieved by allowance for operation of CRS within the vapour-liquid-solid region. Condensed rotational separation is shown to be an economically attractive process for upgrading sour gas fields contaminated with CO2 and/or H2S

Upgrading carbon dioxide/methane mixtures by using a hybrid membrane-condensed rotational separation process

The energy and volume consumption of a hybrid membrane system with a Condensed Rotational Separation distillation process on the permeate gas stream of the membrane is analyzed and compared with a hybrid amine – CRS process. Both energy and volume use can be reduced by at least a factor 2

Condensed rotational separation of CO2

Condensed Rotational Separation is a technique in which flue gas is cleaned by condensation of the CO2 and mechanical centrifugal separation. It requires partial purification of CO2 to concentrations above 50% in the flue gas, prior to separation. This purification can be realized with existing techniques like oxygen enriched coal combustion or CO2 separating membranes. Combined with a partial enrichment technique, Condensed Rotational Separation provides an answer that can compete with promising conventional techniques for CO2 capture, like oxy-fuel combustion or amine absorption. These conventional techniques produce a waste stream with a high CO2 purity that can be compressed to supercritical pressure for transport and storage. It is shown that the energy consumption of Condensed Rotational Separation is only slightly more than gas compression of a sequestration stream resulting from conventional separation techniques. The net result is that the total energy consumption becomes less because of the savings due to partial oxygen/CO2 enrichment
