  • METHOD AND APPARATUS TO REMOVE DEPOSITS
    Publication number: 20130220438
    Abstract: A method of producing and transporting crude oil, comprising extracting crude oil from a well; placing the crude oil in a pipeline to transport the crude oil away from the well, wherein at least a portion of the pipeline travels through an atmosphere having an ambient temperature less than 20° C.; and transporting the crude oil for a first time period at a low flow rate so that a precipitate forms on an inner wall of the pipeline; and transporting the crude oil for a second time period at a high flow rate so that the precipitate is cleared from the inner wall of the pipeline.

  • Method for removal of sulfur dioxide
    Patent number: 6096239
    Abstract: A method for removing sulfur dioxide from gas streams, comprising contacting the gas stream with an aqueous absorption liquid, transferring the liquid to another location, then mildly heating the liquid to recover the sulfur dioxide. This method allows a removal of 99.9% of the sulfur dioxide, the recovery of very pure sulfur dioxide, is resistant to upsets due to variations in the gas stream, and is cost effective.
