Learn about the applications suitable for centrifugal compression technology

70% of the total lifecycle costs for gas compressors come from energy consumption. Recent impeller improvements help compressors produce greater flow utilizing less power than previous designs.

The conditions that cause coupling wear, advantages of the coupling recertification process, and the steps taken to restore product to the original factory warranty.

Unplanned downtime can be incredibly costly when you consider lost production and the stress of having to scramble for replacement parts and staff emergency labor (oftentimes at overtime rates).

Industrial compressors are run at incredibly high speeds under immense pressure every day. This stress causes the rotors inside to naturally warp and bend, creating imbalances over time due to their dynamic nature. If these imbalances go unchecked for too long they can lead to more catastrophic damage, expensive field repairs, and unplanned downtime costs surpassing $2MM per day. Consequently, there are long-standing and recommended balancing practices in place to prevent these problems.

This white paper illustrates how resonant frequency of an accelerometer is determined via Hooke’s Law and the spring-mass harmonic isolator. It also explores the concepts of mass and mounting methodology stiffness, the two main factors that affect the resonant frequency (and therefore high frequency response) of an accelerometer.

Bearings are at the heart of all rotating equipment, yet they are often an afterthought. Neglected until the “heart” stops beating and the equipment is forced to shut down wasting time and money. This paper puts bearings first. It describes methods for more accurate bearing life calculations by examining current bearing protection devices.

As the world becomes environmentally conscious, the Power Generation and Oil and Gas industries have seen mounting pressure to find greener solutions. With a growing demand for greener practices and rising operational costs, it has become imperative for gas turbine operators to cut their carbon footprints, reduce operational costs, and become more efficient. In this whitepaper you will discover that one of the easiest, most cost-effective ways to dramatically reduce CO2 emissions is to upgrade the air intake filters on gas turbines.

Intrinsic safety certifications identify a mix and match of different terms- ATEX, CSA or IECEx? Division or zone? Gas or dust? Pick the sensor with the wrong intrinsic safety certification and run the risk of having the installation stopped by local authorities. This white paper can help you to understand the most common intrinsic safety systems and more, leading you to a more educated decision about which intrinsically-safe vibration sensor is best for your application.

Greene Tweed partnered with MAN Energy Solutions to develop an Arlon®4020 Labyrinth Seal Solution that provides substantial efficiency gain and superior performance when compared to traditional metallic seals. The engineered tooth profile of the Arlon®4020 Labyrinth Seal enables MAN Energy Solutions to reduce leakage and increase efficiency in their compressors.

This paper discusses the expanded market for the capture and use of CO2 in many industrial applications, and how centrifugal compressors aid in these processes
