Rolls-Royce launches RB211 upgrade

Rolls-Royce has launched RB211-Gzero, a retrofit upgrade product to give current users of industrial RB211 aeroderivative gas turbine engines a nominal power increase of 10 per cent, depending on ambient temperature and engine type.

Engineered as a modular package for ease of maintenance, the RB211-Gzero product will specifically benefit operators of the 440-plus worldwide installed fleet of RB211-C and RB211–G variant gas generators that feature RT-56 or RT-62 power turbines.

The RB211-Gzero power increase is achieved during routine gas turbine overhauls by retrofitting applicable RB211 units with a modular package that increases the flow of air through the engine, thereby increasing power availability at ISO conditions by 10 per cent for the RB211-G, and up to 31 per cent for the RB211-C, depending on existing package configuration.

The industrial RB211 gas turbine is available in a power range of 29 to 44 MW and is designed for onshore and offshore oil & gas and power generation applications.

GE produces 100th trailer mounted TM2500

GE has celebrated the production of its 100th trailer-mounted TM2500 aeroderivative gas turbine, which the company describes as a cornerstone in delivering fast, flexible, reliable power generation anywhere at any time.

GE introduced the TM2500 – which it sees as a “power plant on wheels” – more than a decade ago. The milestone unit rolled off the production line at GE’s facility in Veresegyház, Hungary, where GE manufactures all 50 Hz TM2500 packages. GE’s Jacintoport manufacturing facility near Houston, Texas, assembles 60 Hz power generation packages.

“Fast, efficient, reliable power generation – those are hallmarks of the TM2500, and today we celebrate an important milestone as these products are meeting customer demand for fast, temporary or emergency power generation,” said Darryl Wilson, president and CEO aeroderivative gas turbines for GE Power & Water, who made the announcement during GE’s customers’ User Conference.

Construction to drive surge in Russia’s genset demand

Growth in Russia’s genset market will average 9.7 per cent a year between 2010 and 2015, offering rising opportunities across various end-user levels, finds new analysis from Frost & Sullivan.

The market earned revenues of $428m in 2011 and is on track to earn $614.9m in 2015, according to Analysis of the Russian Genset Market. The research covers gas and diesel gensets across key industrial, commercial, institutional and residential end-user sectors. But a booming construction sector is expected to provide the greatest growth opportunities.

“A robust Russian economy and increasing activity in the construction sector will boost the uptake of gensets,” said Frost & Sullivan Research Manager Malavika Tohani.

“The explosion in data centres, backed by the growth in financial institutions around Moscow, will further push demand for back-up power gensets.”

The construction sector will receive a further fillip from a series of sporting events such as Formula 1, the Winter Olympics (in 2014) and the football World Cup (in 2018).

These events are expected to push infrastructure investments in Russia which, in turn, will result in heightened demand for gensets.

Currently, the Russian genset market is primarily driven by industrial applications in the oil, gas and mining sectors. However, economic volatility in Europe could trigger a slowdown in Russia’s export-dependent oil and gas sector that might dampen demand for gensets.

Siemens launches automatic load shedding system

Siemens Infrastructure & Cities has developed an automatic load shedding system for the power supply of large-scale industrial plants, helping to stabilise the networks in critical situations.

Siemens has integrated the “automatic load shedding” function into the Sicam station control system and into Siprotec protection equipment. The solution is based on a distributed architecture and the IEC 61850 communication standard.

The first systems are being launched for use in the oil and gas industry, where industrial networks are often installed to supply power to complex production processes without being connected to the public grid (island networks). If enough power is not available, the load shedding automatically shuts down low-priority loads and restores the balance between power generated and power consumed, enabling uninterrupted operation of high-priority core processes.

A balance of the active power is calculated continuously so that the load is only reduced by the required amount. GOOSE messages (generic object oriented substation events) defined in the IEC 61850 communication standard provide an immediate response to the automatic load shed. The messages are transmitted very quickly via ethernet with high priority, enabling response times of the load shedding function of less than 70 milliseconds.

Yokogawa launches new DPharp EJA transmitters

Yokogawa has introduced a new EJA series of pressure/differential-pressure transmitters based on the company’s unique DPharp digital resonant sensing technology.

Targeted at mid-range applications in industries such as power generation, the new EJA adds new functionality and performance to the original EJA, of which about 5 million units have been delivered to customers around the world since its launch in 1994.

Additional features in the new series include multi-sensing capability, higher-speed response, safety as standard and a more user friendly indicator, all packaged in a more compact and lighter transmitter.

The multi-sensing capability means that a new EJA differential pressure transmitter will be able to simultaneously measure both differential and static pressure. A single new EJA differential pressure transmitter will thus be able to measure both the liquid level and the pressure in a tank.

The response time – the time from the detection of a pressure change to the change in the output of an electric signal – has been brought down to 90 ms, which equals the capability of Yokogawa’s premium EJX series. This faster response time will now allow the new EJA transmitters to be used in high-speed applications such as turbine surge control.

CO2 stored in saline formation in US CCS demo project

A carbon capture and storage (CCS) demo project has begun underground injection of carbon dioxide (CO2) recovered from emissions of a US coal fired power plant.

The demonstration project – run by Japan’s Mitsubishi Heavy Industries (MHI) and US utility Southern Company – is capturing and compressing CO2 from the flue gas of Southern’s Plant Barry in the state of Alabama, and storing it in a saline formation at a depth of 3000–3400 metres in the Citronelle Dome, at a distance of 19 km from the plant.

The storage aspect of the project is being conducted as Phase III of the Regional Carbon Sequestration Partnerships programme, which is being sponsored by the US Department of Energy.

The volume of CO2 injection, which got underway following approval by the Alabama state government, has been progressively expanded and now reached the full-scale target of 500 mtpd. In the project, MHI is responsible for basic planning, engineering, core equipment supply, and provision of technology support.

The facility consists primarily of a flue-gas scrubber, flue-gas CO2 capture/re-generation system, CO2 compression machinery, and electrical components. For CO2 recovery the facility adopts the KM CDR Process, which uses a proprietary KS-1 high-performance solvent for CO2 absorption and desorption that was jointly developed by MHI and Kansai Electric Power Co.

Southern Company is one of the largest energy companies in the US, with a generating capacity of more than 42 GW serving 4.4 million customers.
