Modelling LNG Loading Systems
Background
In this application bulletin we illustrate the use and benefits of PIPENET Transient module in mitigating potential pressure surges and cavitation in LNG loading systems. A number of scenarios are considered before arriving at the optimum philosophy of operation.
In particular we consider the following two aspects of the normal shut down of the system. The simulations pinpoint the strategy for eliminating pressure surge problems.
1. The pressure surge upstream of the shut off valve.
2. Cavitation in the loading arm.
