Covering production, gas transportation, refinery and petrochemical, fuel gas boosting and other similar processes
Our industry milestones include the first high-pressure compressors for ammonia and urea plants, the most powerful compressors for offshore applications (over 30,000 HP) and re-injection compressors with delivery pressures as high as 10,000 psi (700 bar). We continually invest to improve compression technologies through extensive research and development, advanced design capabilities, modern manufacturing techniques and extensive operating data from installations in every corner of the industry. We also provide expert on-site technical support for installation, commissioning, overhaul, repair and maintenance activities – with teams of highly skilled and experienced Field Service Engineers close to our customers in every region.
BCL, RB, VH series
These compressors are designed to cover a wide range of applications and pressures, and they are particularly well suited for sour gas and high-pressure re-injection. Casings can be rolled steel or forged with one or two end covers bolted or secured by shear rings. When practical, diaphragms are 100% machined for improved performance. Radial and thrust bearings are tilting-pad type, and active magnetic bearings are available. End seals are dry-gas type, and other sealing solutions are also available. In addition to conventional labyrinths, inter-stage seals can be abradable or honeycomb to optimize overall machine performance. In-line, back-to-back or double-flow configurations are also available. Our optimized material selection is based on extensive experience in sour and acid gas applications.
MCL / V series
MCL compressors are available in several sizes and pressure ratings, with casings and diaphragms in either cast iron, cast steel or fabricated. Impellers and diffusers are selected from a wide range of standard stages according to application and desired performance. Radial and thrust bearings are tilting-pad type, and shaft-end seals are mainly dry gas seals but can be labyrinths or oil film seals. Inter-stage leakages are controlled by labyrinths (static or rotating) or abradable seals.
For very high flows, our double-flow (DMCL) models allows casing size and speed to remain within an acceptable range to couple the compressor to drivers and/or other compressor casings. Our double-stage (2MCL) models are designed for applications where intermediate cooling or two separate compression stages are required. These compressors have the same general features as MCL units, but with two compression stages in a back-to-back arrangement. Additional side stream nozzles can be provided with the 3MCL model for special requirements such as propane in LNG plants and other refrigeration applications. All connections can be oriented upward or downward to meet plant layout needs.
These integrally geared compressors are used in several petrochemical applications with a wide variety of gases and either low-flow/high pressure or high-flow/low pressure conditions. This type of compressor has a bull gear and from one to four high-speed pinions. One or two impellers can be mounted on each pinion shaft. Optimal impeller speed and the ability to inter-cool compression stages guarantee very high efficiency. Rugged mechanical design delivers very high reliability and easy maintenance.
SRL / DH series
These compressors are used mainly as boosters in petrochemical applications or for recycle in polypropylene and polyethylene plants. The single-stage overhung configuration is simple and easy to maintain. Almost all gases can be handled by this type of compressor with appropriate material selection and seal systems.
With high efficiency and a broad operating range, these axial compressors are designed for high-volume, low-pressure applications. An external, fabricated horizontally split casing holds an inner stator blade carrier. The first stator blading rows are adjustable by external devices for better performance control and broader operability. The number of blade rows is variable to better fit the process needs. Both rotor and stator blades are robustly designed for optimum aerodynamic and mechanical behavior. Radial and thrust bearings are of tilting-pad type. Shaft-end seals can be labyrinths, either with extraction or buffer systems, oil film seals or dry seals, depending on service requirements. All connections can be oriented upward or downward to meet plant layout needs.
