Clean Power at the Black Sea’s Shore (Source: Siemens Energy)

Siemens Energy has received an order from the Russian company OOO RN-Tuapsinskiy NPZ, a fully owned subsidiary of OAO Rosneft, for the supply of six industrial gas turbines. The SGT-800 gas turbine power units, each rated at 47 MW, will be operated in the Tuapse refinery located on the Black Sea. The order brings the total number of SGT-800 units sold to Russia to 29. Rosneft previously ordered seven SGT-800s from Siemens, the latter of which are in the process of being shipped to the Priobskaye oil field in Khanty-Mansiysk.

The six power generating units one of which was the 100th SGT-800 unit to be produced since its introduction are needed for the generation of electricity and steam to accommodate an expansion of the Tuapse refinery’s capacity. The crude oil processed in the refinery is oil produced in Western Siberia and Southern Russia and transportedvia Transneft’s pipeline system and by rail.

Commissioned in 1929, Tuapse Refinery is Rosneft’s oldest refinery. Located in the Black Sea port city of Tuapse in Russia’s Krasnodar region, the refinery is the only such Russian facility on that seacoast.

The refinery’s current capacity is roughly 5 million tones per year. The refinery’s product mix primarily consistsof gasoline, naphtha, diesel and fuel oil. Located adjacent to an oil loading terminal, the refinery exports approximately 90% of its products.

Seeking to more than double the refinery’s capacity to increase its depth from 56 to 95%, Rosneft is now implementing a major expansion and upgradeat the Tuapse Refinery.

Under the first phase of the project, which is scheduled to conclude in 2011, Rosneft will increase Tuapse Refinery’s capacity to 12 million tones per year.

In the second phase of the project, the company will upgrade the refinery’s core processes so that it can produce Euro 4 and Euro 5 gasoline and diesel fuels. This second phase is slated for completion in 2012.

The expansion is where the Siemens supply comes in, with the first three gas turbines scheduled for delivery by late 2010. The remaining three units will follow by the end of 2012. The waste heat recovery parts required to produce the steam will be supplied by others.

The SGT-800’s dry-low emission(DLE) system can achieve low emissions on a wide variety of fuels. Even in a dual-fuel application, the unit achieves low emissions without the requirement of steam or water injection for NOx reduction — be it gas or diesel fuel. The emission requirements for this order operating on natural gas are 50 mg/Nm3 for NOx and 8 mg/ Nm3 for CO.

“Siemens is very pleased to have met the stringent environmental requirements for this project with our advanced gas turbine technology,” said Tom Blades, CEO of the Oil & Gas Division of Siemens Energy. “With 13 SGT-800 gas turbines sold in the Moscow area since 2001, we are able to provide the key components for environmentally friendly, efficient power generation to the Russian market.”

Another important project requirement for the gas turbines being supplied to the Tuapse refinery is their capability to operate on various fuels. The Tuapse site will initially run the gas turbines on liquid fuel and eventually utilize a dual-fuel DLE application with natural gas as a primary fuel and liquid as emergency backup.

“Low life-cycle costs are critical for our customers,” said Jan-Erik Ryden, CEO of the business unit Industrial Applications, Gas Turbines at Siemens Energy. “The environmental friendliness is essentially a free add-on, since the dry-low emission combustion system implemented as a standard design enables achievement of the lowest NOx emissions of all industrial gas turbines on the market. Even when liquid fuels are combusted, it is still possible to comply with legally stipulated emissions limits without the additional need for injection of water or steam.”

In June 2009, the Kolomenskoe gas turbine power plant in Moscow, another plant supplied by Siemens with three SGT-800 machines, went into commercial operation. This cogeneration power plant supplies the Russian capital with 136 MW of electricity as well as 199 MJ/s of district heat, creating an overall plant efficiency of 83%.
