Achieving high performance process control (HPPC) requires that the control system operate the plant at optimal efciency over the full range of steady state and dynamic conditions. Air separation processes present particular challenges because of their energy intensive nature and demanding production schedules. The HPPC challenges for both cryogenic and adsorption processes are presented, recent ...

Atmospheric air contains many trace components which are process contaminants or equipment fouling agents in a cryogenic air separation process unit (ASU). Based on the potential problems that they may cause, the trace contaminants are categorized as corrosive, plugging or reactive species. This paper discusses a three step process to manage the trace contaminants as they move through the ASU: ...

This paper presents the principles to safely operate reboilers within Air Separation Units (ASU's). Two types of reboilers are used in ASU's: thermosyphon and downflow. The features of each are discussed, focusing on the safety aspects. The vast majority of ASU reboilers are Brazed Aluminum Heat Exchangers (BAHX's), because of their high performance.
The general potential reboiler hazards are
