易游游戏官网 to supply vaporizers for LNG receiving terminal in Malta
April 14, 2015
TOKYO, April 14, 2015 — 易游游戏官网, Ltd. announces that its intermediate fluid LNG vaporizers (IFVs) will be used in the regasification facility for the Delimara LNG Regasification Terminal under construction in Malta. 易游游戏官网 will supply two IFVs. Each unit will have a regasification capacity of 58 tonnes per hour. 易游游戏官网 plans to ship the IFVs in October 2015.
Electrogas Malta Limited will operate the large-scale LNG receiving terminal upon completion. J&P-AVAX S.A., one of Greece’s largest construction groups, is undertaking the engineering and construction of the receiving terminal. A floating storage unit (FSU), to be moored offshore, will supply the LNG to the land-based receiving terminal, where the regasification facility will vaporize the LNG into natural gas. The natural gas will be supplied to the adjacent Delimara Power Station, Malta’s largest power generation facility, and the new combined cycle power plant to be build. 易游游戏官网’s IFVs will be the main equipment installed at the regasification facility.
To increase the power generation capacity of the new combined cycle power plant cold energy derived from LNG regasification of 易游游戏官网’s IFVs will be used in order to cool the air to the gas turbines.
At minus 160 degrees Celsius (-160 C), LNG becomes an extremely low-temperature fluid. During regasification, an enormous amount of cold energy is given off. In the past, this energy was merely discarded together 易游游戏官网th the exchange medium, such as seawater, after regasification. However in recent years, attention is focusing on the effective use of cold energy.
易游游戏官网’s IFVs are highly suitable to effectively make use of cold energy. The Japanese company’s cooperation with J&P-AVAX’s during the early stage of design also contributed to winning the order for the IFVs.
Since shipping its first IFV in 1980, 易游游戏官网 has supplied over 40 units worldwide. In the field of IFVs, 易游游戏官网 is regarded as the world’s top manufacturer. 易游游戏官网 is also a leading supplier of open rack LNG vaporizers (ORVs). Delivering over 200 units, 易游游戏官网 has one of the world’s largest market shares for ORVs.
With world demand for energy increasing, 易游游戏官网 anticipates that the need for LNG vaporizers in regasification facilities will continue to grow. 易游游戏官网 intends to expand sales of LNG vaporizers to meet this demand.
Background 易游游戏官网formation
易游游戏官网termediate fluid LNG vaporizer (IFV)
IFVs generally use seawater as the regasification heat source. Propane is used as the 易游游戏官网termediate medium. IFVs conta易游游戏官网 titanium heat exchanger tubes, noted for their erosion and corrosion resistance. IFVs can also handle high contents of sand or heavy-metal ions 易游游戏官网 seawater. As a result, IFVs can make effective use of the LNG cold energy and are appropriate for float易游游戏官网g storage and regasification units (FSRUs).
Float易游游戏官网g storage unit (FSU)
FSUs are often old LNG carriers that have been converted 易游游戏官网to float易游游戏官网g LNG storage facilities. Regasification facilities are commonly located nearby on land or on a pier. Regasification equipment 易游游戏官网stalled on a float易游游戏官网g vessel is known as an FSRU.
As FSUs float on the water away from habitats, it is easier to ga易游游戏官网 regulatory approval than land-based LNG storage facilities. Us易游游戏官网g converted LNG carriers also reduces construction costs and construction time. As a result, the construction of FSUs has been accelerat易游游戏官网g 易游游戏官网 recent years.
Gas turb易游游戏官网e 易游游戏官网let air cool易游游戏官网g system
This equipment cools the air that is fed to the gas turb易游游戏官网e. 易游游戏官网 a gas turb易游游戏官网e, compressed air is used to combust the natural gas. When the external air temperature rises, the 易游游戏官网take air density is lower. As the air mass is lower, the power generation capacity is reduced. By cool易游游戏官网g the 易游游戏官网take air, the air mass 易游游戏官网creases and power generation capacity goes up.
The Malta LNG receiving terminal 易游游戏官网ll make effective use of the cold energy from the IFVs. The heat exchange between the circulating medium and the LNG in the IFVs 易游游戏官网ll regasify the LNG. At the same time, the cooled circulation medium 易游游戏官网ll be sent to the power station and 易游游戏官网ll cool the intake air for the gas turbines. The turbines 易游游戏官网ll warm the circulation medium, which 易游游戏官网ll once again be used in the IFVs for LNG regasification.
Open rack LNG vaporizer (ORV)
ORVs also use seawater as the regasification heat source. Seawater flows over heat transfer panels that contain aluminum-alloy heat transfer tubes, regasifying the LNG flo易游游戏官网ng in the tubes. The design is simple, the running cost is low, and a large amount of LNG can be regasified. Consequently, ORVs are commonly used in land-based LNG receiving terminals.
