Gas Turbines

GE manufactures a complete line of gas turbines for all major Oil & Gas Industry applications. They are installed in natural gas plants, gas compression stations, oil booster stations, petrochemical plants and power generation and cogeneration plants worldwide. GE’s Oil & Gas business has long-standing experience in manufacturing gas turbines dating back to 1961 when a manufacturing agreement was established with GE (U.S.A.) to complement the existing portfolio of products for the petroleum and petrochemical industries (reciprocating and centrifugal compressors, gas engines, pumps, valves, etc.). A proven combination of sound design and quality assurance techniques places these gas turbines among the world’s most reliable. Basic models produced by GE cover the 12,000 to 124,000 kW power range. They can be provided in simple or regenerative cycles for mechanical drive or generator drive applications. Extensive research and development, advanced design procedures, modern manufacturing technology and on-site experience are behind the success achieved by GE gas turbines.

GE10 Gas Turbines

The GE10 is a heavy-duty gas turbine in the 12MW range, available in either a single or a twoshaft configuration. It is the evolution of the field proven PGT10 and incorporates the latest in aerodynamic design, and compact and versatile package arrangements for both Power Generation and Mechanical Drive applications. The cases are horizontally split and the rotor has a disk architecture. The combustion system consists of a horizontally positioned single can. The GE10 is available in both diffusion combustion system and DLN (Dry Low NOx) versions (15/25 ppmvd NOx) and is able to burn a wide range of liquid and gaseous fuels, including Low BTU gas and hydrogen. The GE10 engine design has been highly refined based on the extensive experience gained in operating in all types of environments. There are over two hundred PGT10/GE10 units running under conditions ranging from the cold of Alaska and Siberia to the heat of the desert and the humidity of the tropics. Its efficiency and operational flexibility make the GE10 a cost-effective choice for all applications.

Axial Compressor

The compressor is a high performance, eleven-stage axial flow design with a 15.5:1 pressure ratio derived from GE Aircraft Engine transonic flow aero design technology. The rotational speed is 11000 rpm with a mass flow of 47 kg/s. The antisurge margin exceeds 25%. Advanced 3D airfoils are used for vanes and blades, and the first three rows of stator blades are adjustable to optimize operability. The cold-end drive configuration guarantees reduced flange movement during gas turbine thermal transients. A patented GECC-1 aluminum ceramic coating is provided for application in marine environments.

Combustion System and Emissions

The combustion system consists of a single, slot-cooled combustion chamber assembly that permits easy maintenance of the hot gas path. This combustion chamber can burn a wide range of fuels, from liquid distillates to residuals, to all gaseous fuels including low BTU gas. The broad fuel capability of this combustor is due to the variable geometry design patented by GE. Guaranteed NOx levels of either 15 or 25 ppmvd @ 15% O2 are available over a broad load range. A DLN Dual Fuel version (liquid + gas fuel) is also available.

MS5002C-D Gas Turbines

The MS5002 is a gas turbine specifically designed for mechanical drive applications such as gas boosting, gas injection/re-injection, oil & gas pipelines, LNG plants and gas storage. It has a broad operating speed range to meet the operating requirements of the most common driven equipment (centrifugal compressors and pumps) as well as the ability to burn a large variety of gaseous and liquid fuels. The MS5002 gas turbine was introduced in the market in the 1970s and has been updated and up-rated over the years to meet the industry demand for increased output. Presently two versions are available:

- MS5002C

- MS5002D The MS5002 two-shaft, heavy-duty gas turbine is designed for high operating efficiency over a wide range of speed and load. The simple design and extreme robustness of the MS5002 allow complete maintenance to be performed on site without the need for specialized tooling or service shop assistance. The main features of its design are:

- High pressure shaft consisting of a 16-stage (17 for MS5002D), axial-flow compressor and a

single-stage, high energy turbine. The first stage nozzles are air cooled and the second stage nozzles are of the variable angle type.

- Low pressure shaft is a single stage, high energy turbine.

- Twelve combustion chambers are contained within a single wrapper. A wide range of gaseous

and liquid fuels can be burned. A DLN Combustion System is also available.

- A centralized lube oil system supplies clean, cooled, pressurized oil to lubricate the gas turbine

and the driven equipment including the oil required for any compressor seals. As a consequence of the extremely favorable operating, maintenance and economic characteristics of the MS5002, nearly 500 units (more than 300 manufactured by GE’s Oil & Gas business) have been installed world-wide in all types of environments (arctic, desert, off-shore etc.) always demonstrating ease of operation and very high reliability and availability.

MS5002E Gas Turbines

The most recent addition to the GE family of gas turbines is the MS5002E which delivers high efficiency, low environmental impact and high reliability. This dual-shaft gas turbine has proven its capability for use in power generation and mechanical drive applications. The MS5002E uses GE’s state-of-the-art combustion technology (DLN2.5H) which has accumulated more than 14 million firing hours in the “F/FA” Class GE Frame gas turbine. This model was designed to maintain or exceed the availability and reliability of previous Frame5 models. To maximize hot parts life duration, the firing temperature was kept approximately 100°C lower than that of the “F/FA” Class. Superior efficiency was achieved through the use of advanced design tools to optimize airfoils (for both axial compressor and turbine sections), clearances, leakages and the distribution of cooling flows. Compared to the MS5002C and D or MS5001, the efficiency gain of the MS5002E results in a reduction in emissions of over 20,000 tons of CO2 per year, equivalent to the amount of C02 absorbed by 20 sq km of forest in a year. In addition, the MS5002E NOx emission level is down to 18 ppm. These achievements make the environmental impact of the MS5002E the lowest in its class. The design of the MS5002E was thoroughly validated through an extensive test program that included a full scale test of the axial compressor, and full scale rotordynamic testing and full load testing of the gas turbine system in both mechanical and generator string tests. The MS5002E is ready for the Oil & Gas market and will provide customers with the benefits of a long lasting and reliable machine combined with low environmental impact and low operating costs. The first requisition unit will start at the customer’s site in September of ‘07.
