Our solutions include a wide range of high-pressure piston compressors and diaphragm compressors. From this broad range of compressors, the best possible compressor solution for the customer's specific requirements can usually be found. For especially demanding requirements, however, it may make sense to combine different compressor types.
The NEUMAN & ESSER Seismic Air Power System (NEA|SAPS) has been in the program since 2006. We designed it for the seismic offshore search for oil reserves on the seabed. NEA|SAPS consists of a screw compressor and a V-type piston compressor, both driven by a mid-mounted motor with two ends of the shaft. The screw compressor brings the air from atmospheric pressure to approx. 15 bar. The piston compressor then compresses the air to the desired discharge pressure.
Compared to a solution with a single piston compressor, the NEA|SAPS system is much smaller and lighter and does not transmit vibrations to the ship. In addition, this system requires fewer wearing parts such as suction and discharge valves or piston and guide rings. This reduces maintenance costs to a minimum.
We have also used this SAPS compressor solution in other projects, such as an Enhanced Oil Recovery (EOR) gas production plant. A low suction pressure in the first stage would have required very large cylinders with a high piston weight for a multi-stage piston compressor. We therefore solved the requirement with a solution based on the Seismic Air Power System. The screw compressor in the first stage of CO2 compression makes the large cylinder of the first stage superfluous. This combination of screw and piston compressor requires only one common drive which makes the compressor unit more compact, more efficient and enables more cost-effective operation with minimal maintenance.
Hybrid compressors are machines that combine two compression principles. Our hybrid compressors combine the advantages of piston and diaphragm compressors. They always show their particular strengths when very high pressures and oil-free compression are required.
Our hybrid solution is the answer to the technically very demanding emission-free and oil-free compression. This enables a maximum rod load of 1,700 kN. The output of up to 30 MW generates up to 5,000 bar pressure.
