The Etzel oil and gas cavern system is situated near the North Sea coast, southwest of Wilhelmshaven. A vast salt dome houses the more than 70 caverns that store crude oil and natural gas at depths between 2,953 – 5,577 feet (900 - 1,700 meters). Etzel is integrated in the northwest European oil and gas pipeline network and makes a significant contribution to the safe and reliable supply of gas to Germany and all of Europe.
Prior to processing natural gas from its pure form into liquid natural gas (LNG), undesirable components such as solids, mineral oil coal particles and heavy hydrocarbons are largely removed. Nevertheless, small quantities of these components can reach the compressors installed at the end of the purification process and which transport the natural gas into the pipeline to the liquefaction plant.
The Dock Sud combined-cycle power plant in Buenos Aires, Argentina is designed to adjust the power generation to the fluctuating electrical demand year-round. Managing the high demand during the summer months is particularly challenging, making the requirement for system component reliability a must.
