The Gas Liquid Cylindrical Cyclone (GLCC) separator is an attractive compact separator alternative to the conventional vessel-type two-phase flow separator. Thus, it is important to develop predictive tools for design and to be able to improve the technology of the GLCC. Previous studies on the GLCC have focused on mechanistic models capable of predicting the operational envelope for liquid car...

Economic pressures continue to force the petroleum industry to seek less expensive alternatives to conventional gravity based separation. The gas-liquid cylindrical cyclone (GLCC) is a simple, compact, low-cost separator that can provide an economically attractive alternative to conventional separators over a wide range of applications. Although cyclones have long been used for liquid/liquid, s...

Design and Performance of Passive Control System for Gas-Liquid Cylindrical Cyclone Separators by Ram Mohan, Shoubo Wang, & Ovadia Shoham, The University of Tulsa and Gene Kouba, Chevron Petroleum Technology Company Abstract: The performance of Gas Liquid Cylindrical Cyclone (GLCC) separators can be improved by reducing or eliminating liquid carry-over into the gas stream or gas carry-under thr...

We studied the land-cover data used by the regional climate model REMO and the land surface model JSBACH, for Finland and surrounding areas. To date, the land-cover data determining REMO’s surface parameterisations have originated from the Global Ecosystem classification of the Global Land Cover Characteristics (GLCC-GEC) database. The same database has also been used as basis for prescribed pl...

ABSTRACT Local measurements and 3-D CFD simulations in GasLiquid cylindrical Cyclone (GLCC) separators are scarce. The main objective of this study is to conduct local measurements and 3-D CFD simulations to understand the swirling flow behavior in a cylindrical cyclone with one inclined tangential inlet. Axial and tangential velocities and turbulent intensities across the GLCC diameter (ID=3.5...

Currently, computational fluid dynamics has become the primary method for analyzing flow state inside machine. Herein, Ansys Fluent software is used to design a more effective oil-field device, namely, gas–liquid cylindrical cyclone (GLCC)-horizontal combined separator. The characteristics of mixed flow, turbulence intensity, and phase volume fraction distribution are analyzed, factors affectin...

The metabolic pathways specified by the glc and ace operons in Escherichia coli yield glyoxylate as a common intermediate, which is acted on by two malate synthase isoenzymes: one encoded by glcB and the other by aceB. Null mutations in either gene exhibit no phenotype, because of cross-induction of the ace operon by glycolate and the glc operon by acetate. In this study, the regulation of the ...

Leaf chlorophyll content (LCC) is a prominent plant physiological trait and proxy for leaf photosynthetic capacity. The acquisition of LCC data over large spatial temporal scales facilitates vegetation growth monitoring terrestrial carbon cycle modeling. In this study, global 500 m weekly dataset (GLCC) was produced from ENVISAT MERIS Sentinel-3 OLCI satellite using physical radiative transfer ...
