Abstract:
A method for a treating hydrocarbon well stream that is initially at a first temperature and first pressure, the stream containing components that tend to form solids upon cooling, depressurization, or mixing with other streams, such that the stream is rendered suitable for transport or processing at second conditions comprising a second temperature and a second pressure, at least one of said second temperature and said second pressure being less than said first temperature or said first pressure, the method comprising:(a) passing the stream through an apparatus under conditions so as to promote formation of substantially all solids that would otherwise precipitate downstream at said second conditions so as to form solids and a treated liquid that is substantially free of liquid components that would otherwise precipitate at said second conditions; (b) suspending the solids in the treated liquid by rotating a helical coil in contact with the solid so as to form a solids-containing liquid stream: and (c) transporting the solids-containing liquid stream.
