Compression System suits onshore and offshore projects.

Press Release Summary:

Integrated Compression System uses DATUM® centrifugal compressor technology driven by high-speed, close-coupled motor, with integrated rotary gas-liquid separation unit, packaged with process gas coolers in single module. Since all components are contained in same process module, system can be installed as single unit, eliminating need for large, stand-alone separators and making system suited for developing sub-sea applications.

Dresser-Rand Introduces Integrated Compression System for Onshore and Offshore Projects, Including Sub-Sea

HOUSTON, Sept. 27 -- In a major advance in centrifugal compressor technology, Dresser-Rand Company has announced it is developing a fully Integrated Compression System (ICS) engineered to provide an efficient, compact solution to compression system design.

The Dresser-Rand ICS uses as a platform high-efficiency DATUM(R) centrifugal compressor technology driven by a high-speed, close-coupled motor, with an integrated rotary gas-liquid separation unit, packaged with process gas coolers in a single module. It provides a complete compression system that can be applied to all markets -- upstream, midstream and downstream -- with the smallest footprint, reduced weight and at the lowest total installed cost.

"Traditional compression modules typically are very large and heavy structures, require lengthy production time, and are expensive," said Jesus Pacheco, vice president of Client Services at Dresser-Rand. "With this integrated approach, the total footprint of a conventional module can be reduced by up to 65 percent while its weight can be halved by a Dresser-Rand ICS compression module. It's smaller, it's lighter, and it can be produced in less time. The performance of D-R's ICS, incorporating DATUM compressor and rotary separation technologies will be competitive to the overall performance of traditional systems when the suction scrubber and inlet piping losses are taken into account. This translates into a cost-effective solution that can add real value to our clients' capital projects and operations throughout the life of the equipment."

Dresser-Rand's DATUM centrifugal compressor technology was first introduced to the industry in September 1995 at the 24th Turbomachinery Symposium. Dresser-Rand's DATUM line of centrifugal compressors set the standard for modular design and high-efficiency performance. DATUM units dramatically improved the serviceability of centrifugal compressors, resulting in reduced down time and lower life-cycle costs. To date, more than 500 DATUM units have been sold to clients in more than 40 countries for virtually every type of critical gas compression application. Driving the DATUM compressor line with a high-speed, close-coupled motor ensures a compact design that is environmentally friendly and cost-effective.

Completely Integrated Separator Technology
The ICS' ability to effectively handle any dry or wet gas application is made possible by the integration of advanced rotary separation technology within the compressor. This technology was developed by Multiphase Power and Technologies, a joint venture company created in 1998 between Dresser-Rand and Aker Kvaerner. The joint venture brought together D-R's experience in designing and manufacturing durable and reliable rotating machinery with Kvaerner Process Systems' expertise in separation technology.

In 2005, Dresser-Rand acquired full ownership in Multiphase Power and Technologies. Following the acquisition, Vincent R. Volpe, Jr., Dresser-Rand president and CEO, stated that the move, " ... reinforces Dresser-Rand's 'Total Solutions' approach, designed to offer clients significant value, and complements our existing technologies in the global oil and gas industries." That statement has proved itself with the development of Dresser-Rand's ICS system, according to Pacheco.

Dresser-Rand's rotary separation technologies (RST) provide an efficient and compact method of gas-liquid separation that uses centrifugal forces to separate gas, oil and water and remove solids from the flow. The separation process protects down-line machinery from potential damage by reducing oil content in a single process at the wellhead manifold lowing produced water to be disposed in an environmentally sound manner. An in-line, rotary separator (IRIS(R)) has also been developed for and successfully applied in applications that require the separation of liquids from a gas stream. This separation technology achieves equal or better efficiencies than gravity-based systems while being significantly more compact.

"Oil and gas producers are able to take advantage of these advances in technology to effectively reduce the overall size of production facilities, platforms and sub-sea modules," said Julian Smith, director of Business Development at Dresser-Rand, who heads up the company's Separator Strategic Business Unit. "Downtime and potential production losses are reduced because the equipment is protected from liquids and particles in the pipelines by the separators."

Uniquely Suited for Sub-sea Applications
A key attribute of Dresser-Rand's ICS is that it turns "compressors" into compact "compression systems". We believe this attribute would make it uniquely suited for the developing sub-sea applications. Because the compressor, motor, separation system and gas coolers are contained within the same process module, it can be installed as a single, compact unit and eliminates the need for large, stand-alone separators. The reduced weight and smaller footprint make it very attractive when compared to traditional compressor-only technologies as well as being easier to transport, install and retrieve.

"DATUM compression technology has proved it can provide high-efficiency with maximum reliability thereby reducing life-cycle costs," Pacheco stated. "Combined with other Dresser-Rand technologies, such as the RST, we can offer much more than just a compressor. ICS is a complete compression system in a compact, cost-effective package. As opportunities for sub-sea compression emerge, we expect the Dresser-Rand ICS system to offer the best solutions and provide real value to our clients operating in seabed production."
