Potential of offshore wind energy in Malaysia : an investigation into wind and bathymetry conditions and site selection
The government has set an ambitious target of renewable energy development in Malaysia. As one of promising renewable energy sources, wind energy plays an important role in the Malaysia renewable energy roadmap. Compared to onshore wind energy, offshore wind resources with better quality can be provided in the areas away from the coast, which is more potential to contribute to electricity generation. Wind and bathymetry conditions are two important factors that determine the feasibility and economics of offshore wind turbines. In this paper, an investigation is conducted on wind and bathymetry conditions around Malaysia. The data source is mainly originated from Global Wind Atlas. The conditions of the coastal areas in different states and federal territories of both Peninsular Malaysia and East Malaysia are analysed, with a specific focus on wind speed, wind energy density, and bathymetry conditions in high wind-speed regions. The data and survey is verified and compared with the past published literature. This paper aims to investigate the wind and bathymetry conditions around Malaysia, assess the potential of offshore wind energy, discuss the feasibility of offshore wind turbines, and provide references for the offshore wind development in Malaysia
Phase equilibrium data of mixed carbon dioxide and tetrahydrofuran clathrate hydrate in aqueous electrolyte solutions
The phase behavior of a system consisting CO2 hydrate is of great importance for many industrial and natural processes. On the one hand, CO2 and water are part of natural gas streams and also they are found in oil reservoirs during EOR. In light of this, data for systems containing CO2 and a promoter in aqueous electrolyte solutions are presented. The organic component chosen as promoter is tetrahydrofuran (THF). THF shows a hydrate promoting effect, which is concentration-dependent ≤ 7 mole % of THF in the aqueous solution. At higher concentration, THF shows an inhibition effect of hydrate formation. In contrast, all electrolytes show inhibition effects at all concentrations. Adding electrolyte such as NaCl causes the equilibrium pressure to increase significantly. This is an abstract of a paper presented at the 2007 AIChE Annual Meeting (Salt Lake City, UT 11/4-9/2007).</p
