Distinguished Author Series articles are general, descriptiverepresentations that summarize the state of the art in an area of technology bydescribing recent developments for readers who are not specialists in thetopics discussed. Written by individuals recognized as experts in the area,these articles provide key references to more definitive work and presentspecific details only to illustrate the technology. Purpose: to informthe general readership of recent advances in various areas of petroleumengineering.
The petroleum industry has relied mainly on conventional, vessel-typeseparators to process wellhead production of oil/water/gas flow. However,economic and operational pressures continue to force the industry to seek lessexpensive and more efficient separation alternatives in the form of compactseparators, especially for offshore applications. Compared with vessel-typeseparators, compact separators, such as the gas/liquid cylindrical cyclone(GLCC), are simple, low-cost, low-weight separators that require littlemaintenance and are easy to install and operate. However, the inability topredict GLCC performance adequately has inhibited its widespread deployment.Current R&D is aimed at creating the necessary performance-prediction toolsfor proper design and operation of GLCC separators. This paper presents thestatus of the development of the GLCC, the state of the art with respect to itssimulation and design, and current successful and potential applications.
The GLCC (Fig. 1) consists of a vertical pipe with a tangential inclinedinlet and outlets for gas and liquid. The tangential flow from the inlet to thebody of the GLCC creates a swirl that produces centrifugal and buoyancy forceson the fluids that are an order of magnitude higher than the force of gravity.The combination of gravitational, centrifugal, and buoyancy forces separatesthe gas and liquid. The liquid is pushed radially outward and downward towardthe liquid exit, while the gas is driven inward and upward toward the gasoutlet. The low-cost, low-weight, compact GLCC separator offers an attractivealternative to the conventional vessel-type separator. A size comparisonbetween the GLCC and conventional vessel-type vertical and horizontalseparators has been conducted recently for a typical field application with oiland gas flow rates of 100,000 B/D and 70,000 Mscf/D, respectively, at 100 psig.For this case, the required GLCC inner diameter and height are 5 and 20 ft,respectively. These dimensions are approximately one-half of the correspondingdimensions of the required conventional vertical separator (9 x 35 ft) andabout one-quarter of the dimensions of a conventional horizontal separator (19x 75 ft).
