Abstract: Methods and apparatus for air separation by cryogenic distillation in a double or triple air separation column. The column in the system with the highest operating pressure is said to be operating at medium pressure. All the air to be distilled is pressurized to a high pressure, which is about 5 bar greater than the medium pressure. The air is purified at this high pressure, and a portion of the purified air is cooled in a heat exchange line, while another portion is expanded in a turbine. Part of the cooled air is drawn from the exchange line with a cold booster, which is mechanically coupled to at least one turbine. An energy dissipation device is also provided which is coupled to the turbine not coupled to the cold booster. The energy dissipation device is either another booster, an oil break system, or an electrical generator.

Abstract: Process simulators, including a novel process simulator that utilizes simplified mathematical correlations to predict the performance of equipment or subsystems in a process unit. The process simulator comprises a process correlation that is a mathematical response model for a discrete process system in a process unit. The process correlation is developed by obtaining operating data over a range of operating conditions of the process unit and regressing the operating data to form the mathematical response model. The process simulator calculates a number of output parameters using a number of input parameters. The process simulator outputs the output parameters so they can be used by operating personnel to evaluate the current operations of the process plant and make operating decisions.
