Liquid phase. Pressure must be maintained to keep butane in a liquid state.
Of course it’s the liquid phase. The operating pressure is 0.8–1.0 MPa, and the operating temperature is below 40 degrees; it is sufficient as long as carbon tetrafluoride remains in a liquid state. The level of pressure has little effect on extraction.
The C4 components at the top of the methanol extraction tower in the MTBE plant are in the liquid phase. However, the operating conditions must be carefully considered: the pressure should be 1.0 MPa and the temperature below 40 degrees
