| abstract |
The present invention provides an apparatus for forming particulates of matter in a precipitation chamber, and the apparatus has means for transporting particulates from the precipitation chamber to at least one particle collection chamber downstream of the precipitation chamber. However, the particle collection chamber has an inlet and an outlet separate from the inlet. The present invention also provides a method for forming particulates of a substance, the method comprising contacting a non-gas fluid containing the substance with a dense fluid to diffuse the non-gas fluid in a precipitation chamber, precipitation Carrying the resulting mixture of fluid and particulates from the chamber to a collection chamber, wherein the collection chamber has an inlet and an outlet separate from the inlet. |
