REGASIFICATION SELECTION FOR LNG TERMINAL IN SUDAN

Abstract

The main objective of this research is to select the appropriate regasificationِ technology for Sudan liquefied natural gas (LNG) terminal at Port Sudan, with a low Operating cost to suit the site climate conditions. Computer simulation software was used to design and simulate this technology to realize the optimum conditions which can regasify 3 MMTPA of LNG where this quantity per year is the energy demand of Sudan. Aspen HYSYS 11 was used for the simulation to design and determine the vaporizer specifications and to determine the capital costِ and operation cost. Standard selection criteria were used to select the most suitable regasification technology. In this regard using seawater was found to be the best for both selected options: Direct LNG vaporization using seawater or Indirect LNG vaporization using propane as intermediate between LNG and seawater. The comparison between the two options was implemented by regasification cost. The best option with a regasification cost 0.146 €/MMBTU was found to be the open rack vaporizer (ORV).
