Flexware
Flexware is a turbomachinery engineering company with a
focus on improving client equipment performance, reliability
and maintenance. The company has years of engineering
experience and expertise in equipment design, manufacturing,
testing, troubleshooting and performance monitoring.
Flexware provides consulting services, software and
training for turbomachinery for the petrochemical and power
industries worldwide.
Flexware software and AWM service provides an easy and
accurate means of determining equipment efficiency for gas
turbines, steam turbines and compressors. The service
provides for monitoring of both vibration and performance
of turbomachinery including compressors, steam turbines
and gas turbines. Continuous trending of vibration and
efficiency performance can provide assistance to the
maintenance organisation to make the difference between a
routine maintenance issue and an emergency situation.
Engineering services include rerates, the design of aero
path for compressors and steam turbines along with site
efficiency analysis of equipment and aerodynamic and
mechanical troubleshooting of equipment and operational
problems. Flexware can provide modifications involving
efficiency enhancements, capacity or pressure rise.
A recent job for a client in Mexico involved increased
head and a broader capacity range while maintaining the
constant speed for the gas turbine driver.
Flexware can develop an accurate performance curve for
old compressors with minimal input from the client.
Modifications by Flexware include upgrades to sleeve
seals for reduced leakage rates and improved life, improved
rotor stability via damper bearings or hole pattern seals,
performance enhancements by enhancing impellers, rub
tolerant seals or other aero hardware.
Flexware has provided customised turbomachinery training
worldwide to a broad spectrum of clients for over 20 years.
Elliott
Elliott Group designs, manufactures and services centrifugal
compressors for downstream applications. From distillation
through production, Elliott centrifugal compressors are in
critical service around the globe in refinery and
petrochemical processes, including transportation and
commercial fuels, lubricants, liquefied gases, shale gas,
natural gas byproducts, olefins, petrochemical feedstocks,
and speciality products such as coke and asphalt.
Elliott® compressors are custom designed and
configured for specific process requirements including
cracked gas and refrigeration applications in ethylene and
propylene production, multi-flow refrigeration applications
in LNG liquefaction, and high volumetric flows in propane
dehydrogenation (PDH) processes. The company’s
experience with side stream thermal dynamics and pressure
optimisation has contributed to compressor designs that
merge complex flow streams while maintaining high
polytropic efficiencies. Advanced aerodynamic modelling
has expanded the company’s stage portfolio for high flow
applications. Scalable across the full range of frame sizes,
Elliott’s centrifugal compressors demonstrate the proven
experience required to meet the most demanding
downstream applications.
Extending the operating life of critical compression
equipment is the mission of Elliott Group’s Global Service
operations. Whether responding to an emergency, providing
original OEM parts, executing repairs to installed equipment,
or providing an engineered solution to meet new
performance specifications, Elliott’s Global Service
organisation is recognised for expertise, performance, and
responsiveness. Elliott Field Service teams are dispatched
from regional locations throughout the world to plan,
manage, and conduct planned shutdowns, overhauls,
installations and startups, maintenance, repairs, and
emergency service for turbomachinery from any
manufacturer. Elliott’s global network of full-service repair
centres delivers expert service to repair and restore
rotating equipment from any OEM to ‘like new’
performance and reliability.
