Abstract: A method for forming poly(dimethoxymethane) includes a step of separating a formaldehyde-containing blend into a first bottom stream and a first top stream. The first formaldehyde-containing blend includes methanol, formaldehyde, and water while the first bottom stream includes water. The first top stream includes dimethoxymethane that is produced from the reaction between methanol and formaldehyde. The first top stream is separated into a second bottom stream and a second top stream. The second bottom stream includes poly(dimethoxymethane) while the second top stream includes dimethoxymethane, methanol, and ethanol. The second top stream is separated into a third bottom stream and a third top stream. Third bottom stream includes methanol and ethanol while the third top stream includes dimethoxymethane. The third top steam can be recycled to form additional poly(dimethoxymethane). A system that implements the method is also provided.

Abstract: A system and method for conditioning fuel gas comprises a separator to receive rich gas and to separate NGLs from the rich gas to produce lean fuel gas. A first valve is coupled before the separator to receive the rich gas to expand the rich gas in a throttling or Joule-Thomson effect to reduce the pressure and temperature of the rich gas for the separator. A heat exchanger is coupled before the first valve to transfer heat from the rich gas to the lean fuel gas. The system can further comprise another separator to receive rich gas to separate water from the rich gas to preprocess the rich gas. The system can further comprise a temperature control loop utilizing a slip stream from the separator, a second expansion valve, and another heat exchanger.

Abstract: A lift gas treatment system and method for treating lift gas by a high-pressure separation of heavy hydrocarbons and water from the gas stream to be used as lift gas. The system and method first remove water from the lift gas in a first separator. The lift gas is then cooled in a pair of heat exchangers. A second separator separates natural gas liquids (NGLs) from the lift gas. The NGLs are passed through a valve to reduce the temperature and passed to the second heat exchanger. The lift gas is passed through the first heat exchanger to raise the temperature.
