Designed for the worldwide natural gas market, it serves all major gas-related applications such as gas processing and transportation, gas storage and gas boosting. The shorter stroke combined with a higher rod load, makes it a perfect for air separation, also the technical gas market.
High-Speed Machines with a Long History
NEUMAN & ESSER has a high-speed compressor tradition. In 2000, NEA developed the initial high-speed machine in this series, the 320hs, for natural gas storage. However, this model soon also demonstrated its strengths for further gas applications up to the compression of H2 mix gases. 10 years later, NEA USA successfully entered the midstream gas market and since then has been able to secure large orders for natural gas and CO2 applications, such as for “Enhanced Oil Recovery”.
The Texan colleagues always followed the development of the North American natural gas market. According to the EIA, gas conveyance will grow steadily. The entire natural gas industry is therefore called on to improve its technology with regard to efficiency and zero emission in order to support this growth. As a consequence, larger gas engine drivers will be demanded with compressors capable of handling increased loads.
NEA‘s response to this is its new compressor frame 560hs, developed for electric and gas engines of up to 10,000 BHP at up to 1,200 RPM. Its construction criteria were established by an in-house expert committee, combining the high art of German and Texan engineering while continuously interacting with customers and suppliers.
Major Benefits Through Smart Design Features
The team recognized the necessity to develop a compact compressor with high rod load capabilities to pair easily with the larger engines used in this industry. For this purpose, the crankshaft, main bearing, crosshead and piston rod were taken over from a proven crankcase. Together with a robust cast iron crankcase, these features enable the new construction type 560hs to implement higher gas and inertia forces.
The list of its further advantages is long and impressive. Thus, the 560hs will have the typical feature of a one-piece frame casting including crosshead. Since alignment is essential for the packaging process, the crankcase ensures a true perpendicularity and flatness in reference to the feet and main bearing journals.
Hydraulic bolting has already been a standard feature for several decades. And, the 560hs is no different. This system improves joint strength, ease of maintenance and, most important, safety. It also simplifies assembly at high preload forces. The combination of precision and easy assembly guarantees unlimited operational reliability for thousands of hours.
It is no secret that compact design saves costs. Therefore, the foot mounts for skid installation were subject to a redesign and all the dimensions rethought. Thus, the 4-crank frame with cylinders and distance pieces enables transportation without special road permits.
“The introduction of the 560hs reflects the NEA GROUP’s ability to implement a constructive medium to high-speed compressor solution with outstanding features at short notice. And, it proves that reliability of a new model starts with a robust design”, Scott DeBaldo, President of NEA USA, is happy to state.
