    Optimization of Control Loops and Operating Parameters for Three-Phase Separators Used in Oilfield Central Processing Facilities

    Zhenfeng Li, Yaqiao Li*, Guangjun Wei

    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.3, pp. 635-649, 2023, DOI:10.32604/fdmp.2022.020633

    Abstract In this study, the Stokes formula is used to analyze the separation effect of three-phase separators used in a Oilfield Central Processing Facility. The considered main influencing factors include (but are not limited to) the typical size of oil and water droplets, the residence time and temperature of fluid and the dosage of demulsifier. Using the “Specification for Oil and Gas Separators” as a basis, the control loops and operating parameters of each separator are optimized Considering the Halfaya Oilfield as a testbed, it is shown that the proposed approach can lead to good results in the production stage.

    Influence of Operating Parameters on Unbalance in Rotating Machinery Using Response Surface Method

    Ameya M. Mahadeshwar1, *, Sangram S. Patil1, Vishwadeep C. Handikherkar1, Vikas M. Phalle1

    Sound & Vibration, Vol.52, No.5, pp. 12-21, 2018, DOI:10.32604/sv.2018.03927

    Abstract Wide range of rotating machinery contains an inherent amount of unbalance which leads to increase in the vibration level and related faults. In this work, the effect of different operating conditions viz. the unbalanced weight, radius, speed and position of the rotor disc on the unbalance in rotating machine are studied experimentally and analyzed by using Response Surface Methodology (RSM). RSM is a technique which consists of mathematical and statistical methods to develop the relationship between the inputs and outputs of a system by distinct functions. L27 Orthogonal Array (OA) was developed by using Design of Experiments (DOE) according to… More >
