Analysis of Hydrate Formation Temperature and Water Dew Point of Processed Crude Oil and Gas using Unism Simulator

Flow assurance has been a topic of concern since the start of crude oil and gas production and transportation. The formation of Hydrates is an important issue likely to cause clogs in pipelines during production and transportation of oil and gas. Therefore, production and transportation of such fluids are simulated using software’s like Unism to know the possibility of hydrate occurrence so they can be avoided. This work is based on the simulation of processed well effluents from Rose Field to analyze the hydrate formation temperature and water dew point at different points of the process facility. At the crude oil line the hydrate formation temperature was -69.9565 C, while the water dew point was not defined because it’s a liquid phase. At the gas line the hydrate formation temperature was 4 C at 1803psia and water dew point was -42.7 C. These values are parameters necessary for hydrate formation prediction, hence, they were analyzed and recommendations made to manage effective flow assurance.
