(371i) Flow Rate Data Estimation for LNG Terminal Pipeline

The process of LNG terminal aims to receive LNG from the production site, to store that in liquid state, and to send natural gas in gas phase. In the LNG terminal, whole processes have to be operated in extremely low temperature to maintain liquid state or, there would be a lot of safety problems. To operate safe condition, therefore we need to get as many information as possible. By the way because of cost problem, sensors in terminal is not installed enough and among the sensor types, flow rate sensors are insufficient. In this research, the flow rate data found out through temperature difference and the flow rate data are reconciled by mass balance and several technical correction.
