MSG® 12/14/16 Centrifugal Air & Gas Compressor

MSG compressors are custom designed and built for individual customer needs for a variety of applications. Our MSG style compressors are manufactured with a highly engineered air flow components, designed for easy, low-cost installation and operation.

MSG® Integrally Geared Centrifugal Compressors

MSG (multi-stage geared) compressors offer outstanding design flexibility. MSG compressors are application engineered with numerous available configurations:

· Flows from 70 to 3800 m3/min (2500 to 135,000 CFM)

· Input capacity to over 18,650 kW (25,000 hp)

· Discharge pressures to 100 barg (1450 psig)

Features

Oil-Free Air and Gas

· Prevents system contamination

· Reduces the potential for compressed air pipeline fires caused by oil carryover

· No costly waste disposal associated with oil-laden condensate

· Eliminates the expense and maintenance of oil separation filters at the discharge

High Reliability

· MSG centrifugal compressors are designed to be extremely
reliable due to:

o Conservative high-quality gear design

o Long-life pinion bearing design

o Thrust loads absorbed at low speed

o Stainless steel compression elements

Low Compressor Operating Life Cycle Cost

MSG centrifugal compressors provide better overall operating efficiency than positive displacement or other centrifugal compressors.

· Excellent efficiencies at full load, part load and no load

· Low maintenance cost

· Increased uptime from high-reliability design (limits the need for multiple unit installations for basic reliability reasons)

· No sliding or rubbing parts in the compression process that can cause wear and thereby efficiency loss

Easy Operation/Maintenance

· State-of-the-art MAESTRO control systems

· Fully automated operation for any process conditions

· Machine self-diagnostics

· Compression elements do not wear or require periodic replacement

· Accessible horizontally split gearbox for quick inspection

· Removable intercooler and aftercooler bundles for easy cleaning

Simple Installation

· Compressor, lubrication system, intercoolers, shaft coupling, coupling guard, interconnecting piping, etc. on a common base

· Easy installation with no special foundation requirements

· Easy component accessibility

· Site connection point flexibility

· Reduced floor space required

· Dynamic compression process is pulsation-free, so installation of additional dampening equipment is not required.

Applications

Engineered Air Applications

· Industrial gases

· Instrument air

· American Petroleum Institute (API) standards

· Soot blowers

· Large plant air

· Power industry related

Gas Compressor Applications

· Fuel gas boosting

· Natural gas gathering

· Hydrocarbon refrigeration gas

· Carbon monoxide

· CO2 (wet or dry)

· SynGas

· Low molecular weight recycle gas

· High-pressure nitrogen

· Landfill gas

MSG centrifugal compressors are exceptional by design.

· One, two or three rotors, up to six stages per gearbox

· Horizontal splitline(s) for easy access to parts

GAS FLOW ARRANGEMENT

MSG centrifugal compressors feature an advanced arrangement of gas flow components. Advantages of this arrangement include:

· Directed gas movement to reduce turbulence induced friction

· Air is cooled after every stage to provide high isothermal efficiency
