Gas hydrate formation is a main flow assurance concern in oil and gas production. Understanding the effects of the introduction of solid particles in the slug flow is essential to improve the efficiency and safety of multiphase production. The purpose of the present work is the experimental characterization of solid‐liquid‐gas slug flow with the presence of dispersed hydrate‐like particles. Experimental tests were carried out with inert polyethylene particles of 0.5‐mm diameter with density similar to gas hydrates (938 kg/m3). The test section comprised a 26‐mm ID, 9‐m length horizontal duct of transparent Plexiglas. High Speed Imaging and resistivity sensors was used to analyze the slug flow unit cell behavior due to the introduction of the solid particles and to measure the unit cell translational velocity, the slug flow frequency, the bubble and slug lengths, and the phase fractions. Two distinct concentrations of solid particles were tested (6 and 8 g/dm3). © 2018 American Institute of Chemical Engineers AIChE J, 64: 2864–2880, 2018

水平三相固液气弹团流量的测量:水合物样颗粒对流体动力学的影响

天然气水合物的形成是油气生产中主要的流量保证问题。了解在团状流中引入固体颗粒的影响对于提高多相生产的效率和安全性至关重要。本研究的目的是在存在分散的水合物样颗粒的情况下对固液气团塞流进行实验表征。实验使用直径为0.5毫米的惰性聚乙烯颗粒进行,密度与气体水合物(938 kg / m 3)类似)。测试部分包括一条26毫米内径,9毫米长的透明有机玻璃水平管。高速成像和电阻率传感器用于分析由于引入了固体颗粒而引起的团状流动晶胞行为,并测量了晶胞平移速度,团状流动频率,气泡和团状长度以及相分数。测试了两种不同浓度的固体颗粒(6和8 g / dm 3)。©2018美国化学工程师学会AIChE J,64:2864–2880,2018
