Petasense
Petasense, an Industrial Internet of Things (IIoT) start-up, was
founded with a vision of making industrial machines smarter.
The company offers an end-to-end system that provides
real-time information about equipment health, leading to
reduced unplanned downtime, increased availability and
safety.
The key products offered by Petasense are:
Vibration Mote – wireless, triaxial vibration and surface
temperature sensor for continuous condition monitoring
of rotating equipment. A compact, battery-powered
device that transmits data over standard WiFi to the
ARO Cloud.
Transmitter – wireless, multi-sensor input module that
supports up to nine sensor channels. Plug in any third
party industrial sensor (4 – 20 mA or 0 – 30 V) and
transmit data over standard WiFi. This allows companies
to collect asset condition and process data
(e.g. temperature, pressure, current, flow, ultrasound, and
hundreds of other inputs). Power options include battery
or wired (power-over-ethernet).
ARO Cloud – cloud-based web and mobile applications
provide a way to monitor real-time asset health and
perform advanced analysis of raw data. Machine learning
algorithms, coupled with a comprehensive library of
assets and their failure modes, are used to assess the
health of equipment and generate a real-time asset
health score. It easily integrates with plant systems such
as historians, EAM, SCADA, and other analytics platforms.
The software combines advanced functionality needed
Mitsubishi Heavy Industries
Compressor International
Mitsubishi Compressor International (MCO-I), together
with parent company Mitsubishi Heavy Industries
Compressor Corp. (MCO), is recognised globally as a
premier global supplier of compressor and steam turbine
packages for petrochemical and downstream applications.
MCO also designs and manufactures compressors and
steam turbine packages for a range of applications such as
upstream, midstream, downstream and LNG.
A major part of the petrochemical industry is
constituted by the plastics (polymer) industry. The global
demand for plastics is constantly increasing and therefore
there is a significant push to increase the capacity of
ethylene plants in order to increase productivity. MCO has
over 100 years of experience supplying high quality,
custom-engineered, large capacity centrifugal compressors
for over 100 ethylene crackers worldwide and other
petrochemical plants such as ammonia, methanol, PDH and
olefins.
Ethylene plants typically have cracked gas compressor,
refrigeration compressors for ethylene and propylene
production. The power and efficiencies required for such
applications can be achieved by large frame compressors
(i.e. compressors with large flow coefficient impellers)
matched with a highly efficient steam turbine. MCO also
has experience in supplying steam turbines with varied
operating speeds and high power rating, i.e. 90 MW.
The most important thing at refineries and
petrochemical chemical plants is efficiency and reliability of
rotating equipment. MCO’s mission has always been to
provide innovative solutions for downstream plants that
increase productivity while lowering operational costs.
MCO’s comprehensive portfolio is not just limited to
providing new equipment but also providing services such
as field service, repair, maintenance, installation and
commissioning, equipment storage, high speed balancing of
rotors and foot print replacements. MCO recently had
great success by increasing plant capacities by footprint
replacements, i.e. the process of replacing an existing steam
turbine or compressor rotor or casing with a new machine
specifically designed to meet increased performance
requirements utilising an existing foundation and piping fit.
MCO’s recent projects include compressor and steam
turbine packages for the following:
A 1.4 million tpy ethylene plant and a large
900 000 tpy PDH plant in China.
A 500 000 tpy PDH plant in Kazakhstan.
A 5000 tpd methanol plant in Russia.
A refinery in the Middle East.
DWE® reactors also belong to the turbomachinery
product portfolio. The product range includes reactors and
heavy apparatus for chemical and petrochemical processes
(e.g. fluid catalytic cracking), as well as physical process
systems.
Steam turbines are available for both mechanical drive
as well as power generation applications up to 160 MW,
while the gas turbine portfolio covers the range between
6 – 13 MW. The company offers the following:
Compressors:
Centrifugal compressors.
Pipeline compressors.
Integrally geared compressors.
Isothermal compressors.
Hermetically-sealed motor-compressor systems with
active magnetic bearings.
Axial compressors.
Process gas screw compressors.
Gas turbines (6 – 13 MW):
Mechanical drive.
Power generation.
Steam turbines (1 – 160 MW):
