Abstract

Natural Gas Transportation requires Natural Gas to be in its Liquid state, liquefying Natural Gas requires decreasing temperature to a very low level. This requires severe temperature and pressure conditions. This paper will discuss a risk assessment study on a Node in the plant of Natural Gas, which is the propane heat exchanging unit, which decreases the temperature of the flow gradually at the beginning to remove heavy liquids. Risk assessment study is applied using three methods, HAZOP, DMRA and LOPA.
