Global Energy Trend and Evolution of NOCs
Kim, Hee-Jip ;
Journal of Energy Engineering, volume 16, issue 2, 2007, Pages 53~57
High oil prices and high demand supporting IOC move to frontier and NOC evolution. Most frontier area reserves are in NOC territory. IOCs need to be able to manage relationships with NOCs in order to be successful. They need to tune into what NOC priorities are. NOCs have different priorities depending on whether they are resource rich or resource poor. IOCs need to recognize
priorities and differentiate themselves by using them when talking to NOCs.
GTL(Gas-to-Liquid) 기술 현황
Jun, Gi-Won ;
Journal of Energy Engineering, volume 16, issue 2, 2007, Pages 58~63
In recent years, the technologies for the production of synthetic fuel from natural gas have been attracting considerable interest because of high oil prices. While oil prices remaining high, GTL (Gas-to-Liquids) technology would provide an attractive option for utilizing gas resources. Furthermore, GTL fuels contain almost zero sulfur and low aromatics and have a very high cetane so that they are estimated to be environmentally friendly diesel fuels able of meeting the advanced fuel specifications of the 21st century. GTL process generally consists of three primary steps: synthesis gas production from natural gas reforming, hydrocarbon production from synthesis gas by Fischer-Tropsch (F-T) synthesis, product upgrading by hydrocracking/hydroisomerization. This paper presents a brief summary of GTL technology and worldwide development trend about it focusing on the reforming of natural gas and the F-T synthesis.

During the 2nd World War, several Coal-to-Liquid (CTL) plants were operated in Germany and England to convert coal to large volumes of liquid fuel. Big oil fields discovered in the Middle East after the war supplied crude oil at the low price and all CTL plants were forced to shut down. However, South Africa (Sasol) built a CTL plant in 1955 and 2 more plants afterward and the current production of coal-derived synfuel reached 150,000 bbl/day. Recently, the sustained high crude oil price and the fear of the "peak oil" rejuvenated the interest of CTL and several CTL projects are in progress. China established a plan to build CTL plants with the total capacity of 30 million tons of synfuel per year by 2030. China is building a direct coal liquefaction plant which is scheduled to produce 20,000bbl/day of synfuel in 2008. There are 8 CTL projects in USA either in the planning stage or in the ground-breaking stage. CTL projects are also carried out in Australia, Philippines, New Zealand, Indonesia and India. Korea needs to approach the CTL project in the perspective of the national energy security. In this paper, the history, the status, current activities and the prospect of CTL are described.
The Status of DME Development and Utilization as a Fuel

World energy demand has been dramatically increasing because of using much energy of developing countries in Asia. The other side, conventional fossil fuels supply has been gradually decreasing due to the limitation of fossil fuel reserves and changing to the use of environmental-friendly energy for prevention the emission of carbon dioxide, NOx and SOx. Based on these times and status, we get the n necessity of the conversion of environmental-friendly energy and the high effective utilization of conventional and unconventional energy. Recently, promised DME fuel as environmental-friendly and substituted oils will be introduced the status of technology and market in domestic and foreign.

In view of stringent environment regulations to control the emission of green house gases and also depleting fossil fuel reserves, it is high quality desirable to develop alternative technologies to produce high quality fuels. To this end Biomass to Liquid (BTL) technology has received much attention in recent years. BTL process generally consists of gasification of biomass to produce bio-syngas, cleaning and control of
mole ratio of bio-syngas and Fischer-Tropsch synthesis & upgrading systems. Choren, Germany has first developed the commercial BTL process using unique gasification system i.e., Carbo-V. A new technology to remove tars and BTX has been developed by ECN in Netherlands employing a gasification system combined with OLGA technology. Several other countries including USA and Japan are showing great interest in BTL technology. Thus in view of our national energy security and also the environmental regulations, it is essential to develop alternative technologies like BTL in order to meet the increasing demand of energy though our insufficient biomass resources. In this paper we present an overview and development status of BTL-diesel technology.
