DESIGN AND PERFORMANCE OF GAS LIQUID CYLINDRICAL CYCLONE SEPARATORS by Gene E. Kouba, Chevron Petroleum Technology Company Ovadia Shoham and Siamack Shirazi, The University of Tulsa th Presented at the BHR Group 7 International Conference on “Multiphase 95”, Cannes, France, June 7-9, 1995 ABSTRACT Current separation technology based on the conventional vessel-type separator is several decades old. The vessel-type separator is large, heavy and expensive to purchase and operate. Recently, the petroleum industry has shown interest in the development of innovative alternatives to the conventional separator that are compact and low weight, and have low capital and operational costs. One such alternative is the Gas Liquid Cylindrical Cyclone (GLCC) separator. Very few studies are available on the optimum design and performance of GLCCs. Consequently, the sizing of GLCCs and estimation of the operational envelope are based on limited experience, without a high degree of confidence. This paper presents new experimental laboratory data and limited number of field data on the flow behavior and performance of the GLCC separator. Also, initial mechanistic models that describe the flow behavior in the GLCC are presented and compared with the experimental data. These provide the state of the art for the design of GLCCs for the industry. INTRODUCTION The Petroleum Industry has relied heavily on the conventional vessel-type separation technology, which has not changed substantially over the last several decades. Conventional separators are bulky, heavy and expensive in capital and operating costs. These limitations are felt most severely in offshore operations where platform costs are escalating.
