Gazprom commissions new CCGT-450 unit in St. Petersburg
November 30 2012 -
Gazprom recently commissioned a new CCGT-450 combined-cycle gas turbine unit at the Pravoberezhnaya combined heat and power plant (CHPP). This is the third large-scale project for building state-of-the-art combined-cycle gas turbine units implemented by Gazprom over the recent years in Saint Petersburg, after the commissioning of CCGT-450 at the Yuzhnaya CHPP and two CCGT-180s at the Pervomaiskaya CHPP.
Centrax Gas Turbines will install and commission 17 generating set packages in three major Russian fields gearing this year. Twelve of the packages, each comprising a single 5.2MW Rolls-Royce 501 unit, are being installed for the Ust Teguss field in the Tyumen region, on the West Siberian Plain some 1600km east of Moscow.
Not so long ago users tended to order turbines, compressors and auxiliary equipment from OEMs and a cast of thousands. Equipment often arrived piecemeal and had to be cobbled together on site – an inefficient, time-consuming and expensive proposition. Understandably, a better mode of operation was desirable. OEMs and partners, such as Kawasaki, Pratt & Whitney, Centrax, Elliott Group, Solar Turbines and GE Oil & Gas, began to take on the role of packager. They provided end users with an integrated system – ready to ship and rapidly implemented.
Alstom signed two orders worth about $96 million with Metka S.A., an international contractor for large scale energy projects to deliver power generation equipment for key projects that Metka is executing for the Samra Electric Power Co. in the Kingdom of Jordan.
Gas turbine OEMs are targeting the renewable energy market with machines that can respond quickly to match the total load demand of fluctuating renewable power while maintaining grid stability. GE Energy’s LMS100, in particular, is finding broad application in areas such as California, which boast high renewable portfolio standards.
ABB has announced a breakthrough in the ability to interrupt direct current, solving a 100-year-old electrical engineering puzzle and paving the way for a more efficient and reliable electricity supply system.
After years of research, ABB has developed the world's first circuit breaker for high voltage direct current (HVDC). It combines very fast mechanics with power electronics, and will be capable of 'interrupting' power flows equivalent to the output of a large power station within five milliseconds.
Elliott Group has opened a regional office in Abu Dhabi, the United Arab Emirates, to support growing demand for Elliott equipment and services in the Middle East. The Abu Dhabi office extends Elliott's presence in the region and expands Elliott's ability to offer local sales and service support.
Over the past 70 years, Elliott has supplied more than 600 compressor and steam turbine casings to producers in the region.
A case study on hydrate formation in centrifugal compressors was presented at the recent Turbomachinery Symposium in Houston, Texas, by Orlando Donda Filho, Senior Engineer, Petrobras, Eder Ramalho, Fleet Manager, Caterpillar Solar Turbines, Macaé and Pedro Antonio Lima Donda, Senior Maintenance Technician, Petrobras. Below are the excerpts:
Two Mercury gas turbines will serve cogeneration needs of a 240,000 sq. feet data center in Manhattan. The turbine exhaust will drive the adsorption chilling system, which will consume little parasitic power. Some of the waste heat will be used to generate steam for winter heating.
