Wobbe Index (WI) is the main indicator of interchangeability of fuel gases.

WI = Higher heating value/(square root of gas specific value)

Wellhead gas and associated gases cover Wobbe Index from HCV to LCV with increasing contents of inert gases (“rare gases”)

WI-range of standard pipeline quality gas from 37 to 49MJ/Nm3

Wobbe Index (MJ/Nm³)

Siemens has experience in selected applications outside standard fuel range using non -DLE combustion system.

A few DLE experiences exist with MCV- fuel

Yadana is an actual order with 2 X SGT400; WI= 28MJ/Nm3

Notes : DLE = Dry Low Emission

Wobbe Index (MJ/Nm³)

Siemens has experience in selected applications outside the standard fuel range using non-DLE diffusion flame combustion

sgt 100 in chp for a gas platform the north sea tidelands germany
Offshore oil field located on the Southern edge of the Wattenmeer National Park

Gas produced cannot be flared for environmental reasons

Solution:

One SGT-100 gas turbine

Output 4.9 MWe

DLE combustion system

First Application of DLE offshore

“Rich” gas composition with Wobbe Index >50MJ/m3

Temperature corrected Wobbe@ 78oC – 48MJ/m3

Total DLE hours approximately 59,000 hours

Significant reduction of emissions : 80-90% reduction of NOx

SGT-100 in CHP for a gas platformThe north sea tidelands - Germany
sgt 200 for a oil field tyanskoe oil field russia
First application of its kind in Russia (Western Siberia) burning wellhead gas which was previously flared

Solution:

Three SGT-200 gas turbines

Output 6.75 MWe each

DLE combustion system

Guaranteed NOx and CO emission levels of 25ppm

Min. air temp. (-57oC)

Max. air temp. (+34oC)

Gas composition with Wobbe Index >45MJ/m3

Total DLE hours approximately 22,000 hours for each unit

Significant reduction of emissions : 80-90% reduction of NOx level

Siemens has supplied >110 gas turbines for power generation, gas compression and pumping duty throughout the Russian & FSS oil & gas industry

SGT-200 for a oil fieldTyanskoe Oil Field - Russia
sgt 400 for a new gas platform yadana gas field myanmar
New platform in the Yadana gas field in the Andaman Sea off the coast of Myanmar

Solution:

Two SGT-400 gas turbine-driven compressor trains

Output 13.4 MW each in mechanical application

Dual-fuel DLE combustion system

MCV gas composition with Wobbe Index 28 MJ/m3

Gas containing up to 24% N2

Units will be used to supply gas to the domestic market and to three power plants in Bangkok conurbation in Thailand

Delivery scheduled for May 2007

Siemens is committed to develop its DLE technology to reduce emmissions and meet market requirements

summary
Summary
  • Siemens has experience in selected Up- and Mid-stream Oil & Gas applications with non-standard fuel range and with DLE combustion system :
    • Siemens industrial gas turbines are particularly environmentally friendly and economical thanks to their lower fuel consumption and low emissions
    • Siemens is committed to reducing NOx emissions and continues to develop its DLE technology
    • Fuels outside the range or constituents outside of specifications are handled on a case-by-case basis
  • Siemens’ strategy is to develop its DLE combustion technology while maximising fuel flexibility, ambient temperature and load range
