Abstract
The gas-liquid cylindrical cyclone (GLCC) separators is a fairly new technology for the oil and gas industry. The current GLCC separator, a potential alternative for the conventional one, was studied, developed, and patented by Chevron company and Tulsa University (USA). It is used for replacing the traditional separators that have been used over the last 100 years. In addition, it is significantly attracted to petroleum companies in recent years because of the effect of the oil world price. However, the behavior of phases in the instrument is very rapid, complex, and unsteady, which may cause the difficulty of enhancing the performance of the separation phases. The multiple recent research shows that the inlet geometry is probably the most critical element that influences directly to the performance of separation of phases. Though, so far, most of the studies of GLCC separator were limited with the one inlet model. The main target of the current study is to deeply understand the effect of different geometrical configurations of the circular inlet on performances of GLCC by the experimental method for two phases flow (gas-liquid). Two different inlet configurations are constructed, namely: One circular inlet and two symmetric circular inlets. As a result, we propose the use of two symmetric circular inlets to enhance separator efficiency because of their effects.
Highlights
THE gas-liquid cylindrical cyclone (GLCC) (Figure 1) consists of a vertical pipe with a tangential inclined inlet and outlets for gas and liquid
The separation efficiency of the device will be higher when using two symmetric inlets and we suggest the application of two symmetric square inlets type that is the same angle of inclination and the area of the nozzle with the unique inlet configuration to improve separation efficiency in GLCC
It creates a more axis symmetric flow at the center line, which would improve the uplift of air bubbles in the performance of GLCC
Summary
THE GLCC (Figure 1) consists of a vertical pipe with a tangential inclined inlet and outlets for gas and liquid. The flow generally consists of a liquid vortex with a gas-core filament. They have potential applications, complex phenomenon affecting the separating efficiency have not been studied completely in the past [1,2,3,4,5,6]. This difficulty in predicting accurate the performance of the GLCC has been the single largest obstruction to the wide use of the GLCC. The GLCC performance is dependent upon the tangential velocities of
