Venturi Wet Gas Flow Modeling Based on Homogeneous and Separated Flow Theory
When Venturi meters are used in wet gas, the measured differential pressure is higher than it would be in gas phases flowing alone. This phenomenon is called over-reading. Eight famous over-reading correlations have been studied by many researchers under lowand high-pressure conditions, the conclusion is separated flow model and homogeneous flow model performing well both under high and low pre...
متن کاملEvolution of Wet Gas Venturi Metering and Wet Gas Correction Algorithms
The Venturi meter is a straightforward pipeline device used for the metering of gas and liquids. This article presents a brief summary of the creation and characterisation of the modern Venturi meter, including the historic development of public domain algorithms to derive two phase (gas and liquid) flow rates from differential pressure measurements. The use of Venturi meters in multiphase oil ...

شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
Flow of wet granular materials.
The transition from frictional to lubricated flows of a dense suspension of non-Brownian particles is studied. The pertinent parameter characterizing this transition is the Leighton number Le=eta(s)gamma / sigma, the ratio of lubrication to frictional forces. Le defines a critical shear rate below which no steady flow without localization exists. In the frictional regime the shear flow is local...
متن کاملExperimental and Theoretical Study of the Gas-water Two Phase Flow through a Conductance Multiphase Venturi Meter in Vertical Annular (wet Gas) Flow
Annular gas-liquid two phase flow is widely encountered in the nuclear industry. Various combinations of techniques have been employed in annular gas-liquid two phase flows to measure the flow parameters (e.g. liquid film thickness, gas volume fraction and the phase flow rates). One of the most useful techniques which has proven attractive for many multiphase flow applications is the electrical...
