With the aim of reducing global CO2 emissions as quickly as possible, environmentally friendly natural gas is increasingly replacing fossil fuels such as diesel, gasoline and oil. The development of new natural gas sources and the construction of new liquefaction plants are also driving further growth in international natural gas trading and transport and storage capacities. In addition, natural gas storage is also playing an important role. In many cases, underground salt caverns are used for this purpose. After the salt deposits have been exhausted from the cavern, the cavern is flushed out and is then available for storage. To transport the gas to the underground storage facilities, NEUMAN & ESSER compressors are used to compress the gas to the cavern or storage pressure. For withdrawal, the gas is then expanded back to the appropriate pipeline pressure.
Fuel gas compressors are used to drive gas turbines or reciprocating engines with a gaseous fuel, such as natural gas or biogas. Such engines require a steady supply of fuel gas at constant pressure. NEUMAN & ESSER fuel gas compressors are used, for example, when the supply pressure of the LNG pipeline is not efficient for a high-power gas turbine. Such turbines operate at over 40% efficiency and require a stable inlet pressure of ~50bar/~725 psig.
The gas injection process lowers the density of existing oil while increasing reservoir pressure by forcing gas back into the reservoir. As a result, production and utilization rates can be increased. NEUMAN & ESSER compressors compress the gas to be injected into the reservoir from the current reservoir pressure to the corresponding required final pressure. The requirements of the constantly decreasing reservoir pressure, i.e. the suction pressure, as well as any modifications to the compressor system that may be necessary in the future, must be taken into account during the initial engineering stage.
An oil or gas production field typically produces from many different reservoirs. For the purpose of efficient further processing, central collection points, gas gathering stations, are created in which harmful production by-products such as acid gases (hydrogen sulfide, carbon dioxide), water or mercury are removed so as not to damage downstream pipelines and equipment.
NEUMAN & ESSER compressors are used in this process to compress the natural gas to a sufficient pipeline pressure (~1400 psig) and at the same time to remove harmful accompanying substances such as H2S from the gas. In doing so, it is important to meet the requirements of the process and the materials caused by contaminants such as H2S.
