Abstract:
1. A method for treating a slurry, comprising: increasing a first pressure of the slurry to a second pressure with a first float-type pump to form a second pressure slurry; then increasing a first temperature of the second pressure slurry to a second temperature to form a second pressure, second temperature slurry in a first heat exchanger with a first heat transfer medium that is different than fluid in the second pressure, second temperature slurry; then changing the second temperature of the second pressure, second temperature slurry to a third temperature to form a second pressure, third temperature slurry; then decreasing the third temperature of the second pressure, third temperature slurry to a fourth temperature to form a second pressure, fourth temperature slurry in a second heat exchanger with the first heat transfer medium; then decreasing the second pressure of the second pressure, fourth temperature slurry to a third pressure to form a third pressure, fourth temperature slurry with a second float-type pump; and discharging the third pressure, fourth temperature slurry.
