ABSTRACT

There has been a recent renewal of interest in North American LNG import terminals, as the worldwide gas market is continuing to grow. This paper reviews conventional LNG import terminal designs, includingthe process and major fadors impacting the terminal cost. Recently, companies have approached KBR regarding future possibilities, specifically floating re- gasification units, and integrating LNG import terminals with electric power generation plants. These developments will lead to f~-for-purpose,low cost LNG import terminals for the ultimate benefdof consumers.

INTRODUCTION

    LNG trade volume has been steadily increasing by about 9% per year for the last two decades. This trend is expected to continue as general energy demand rises and natural gas is becoming power plant fuel. An LNG receiving terminal is a key component of an LNG chain. The role of a terminal is to receive, store, vaporize, and sendsut the re-gasified natural gas to customers with high reliability. A total of 42 LNG receivingterminals, excluding LNG peak shaving facilities, are currently operating.

    Technology advances have been brought in different areas of an LNG chain, resulting in LNG production and transportation cost dramatically reduced. The plant reliability and safety in handling LNG have also increased. These efforts make LNG have a high competitiveness against other energy sources: coal energy and nuclear power. The paradigm of the role of LNG receiving terminal has been changing with the new innovative technologies in designing LNG receiving terminals, which must be designed on a fit-for-purpose basis to meet the unique situation at each project condition.

   This paper reviews the LNG receiving terminal process and main equipment currently in common practice by KBR, who designed over 80% of LNG receiving terminals outside of Japan. This paper also presents new innovative conceptual designs, which bring high operational reliability and economical benefits. These involve floating re-gasification units and thermal integrationwith a power plant.

THE LNG RECEIVING TERMINAL PROCESS

   The LNG receiving terminal (RT) receives liquefied natural gas from LNG camers, stores the LNG in storage tanks, vaporizes the LNG, and then delivers the natural gas into a distribution pipeline. The receiving terminal is designed to deliver a specified gas rate into a distribution pipeline an...
