The State-of-the-Art of Gas-Liquid Cylindrical Cyclone Control Technology: From Laboratory to FieldSource: Journal of Energy Resources Technology:;2010:;volume( 132 ):;issue: 003::page 32701DOI: 10.1115/1.4001900Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Conventional gas-liquid separators are vessel-type with simple level and pressure control since the residence time is large. Compact gas-liquid separators, such as gas-liquid cylindrical cyclone (GLCC© —gas-liquid cylindrical cyclone—copyright, University of Tulsa, 1994), have emerged recently as alternatives to reduce size and increase separation efficiency for onshore, offshore, and subsea applications. As compared with the vessel-type separators, compact separators are simple, low-cost, low-weight, require little maintenance and are easy to install and operate. However, the residence time of the GLCC is very small. Consequently, it can be destabilized easily due to high flow variations at the inlet, for example, slugging, without the aid of fast and accurate control systems. In the past, lack of understanding of control system dynamics and design tools has prevented this technology from fast field deployment. The objective of this study is to present a review of the compact gas-liquid separator (GLCC) control technology. This includes the development of control strategies, control system design, dynamic simulation, experimental investigation, and field applications. The performance of compact gas-liquid separator (GLCC) strongly depends on the liquid level and/or separating pressure. In this investigation, several control strategies have been presented for field applications of gas-liquid compact separators. Especially, an optimal control strategy was developed for handling slug flow and optimizing the system performance in terms of reduced or eliminated liquid carry-over or gas carry-under. The developed strategies have been used for the design of several hundreds of GLCC applications, currently in operation in the field. Details of some of these applications are also presented. This study provides the state-of-the-art of gas-liquid compact separator control technology from the laboratory to the field.
