Abstract
Hydrate management is a strategy that can be used in deep-water oil exploration in which hydrates are allowed to form, but under control so that pipeline blockage is avoided. In this case, the formed hydrate particles are transported within the liquid phase, resulting in a slurry flow. In this sense, the impact of these solids on the flow hydrodynamics is of consider interest of the oil industry. Despite the importance of the topic, very little is known regarding hydrate particle transportation. In face of the exposed, the present work aims to understand the effect of the solid concentration in parameters such as the system pressure drop, the mean liquid level in the pipe and the flow configuration itself, under stratified flow condition. For that, air, water and polyethylene particles, which mimics the hydrates, were used as the working phases and put to flow in a loop which has a 34 m long, 50 mm of inner diameter test section. The main results show that particles have a minor impact on the liquid mean height while increasing the system pressure drop. Also, due to poor transportation capacity at low phases’ superficial velocity, resulting in particle accumulation in the pipeline, intermittent transportation of solids by means of structures that resemble slugs prevailed at 10 and 20% v/v particle concentration.
