Abstract
Natural gas liquids (NGLs) are valuable by-products of the raw natural gas. A variety of process schemes have been developed over the years for an economical, safe and efficient extraction of these components including the conventional, cold residue recycle (CRR), and the gas subcooled process (GSP), each comprising a range of competing advantages. In this work, the operability of these NGL recovery technologies is evaluated in terms of the controllability and process dynamics. The evaluated configurations are analyzed qualitatively in order to recognize their ability of achieving main control targets and reducing the process upsets due to typical disturbances. The main goal foresees the assessment of control schemes capable of guaranteeing robustness and performance during the operation while highlighting the importance of developing a structurally sound control strategy.
