New Solution for the Control of Performance and C1C6+ Monitoring

Gas turbine engines derive their power from burning fuel in a combustion chamber and using the fast flowing combustion gases to drive a turbine in much the same way as the high pressure steam drives a steam turbine. To minimise the size and weight of the turbine for a given output power, the output per pound of airflow should be maximised. This is obtained by maximising the air flow through the turbine which in turn depends on maximising the pressure ratio between the air inlet and exhaust outlet.

Thermal efficiency is important because it directly affects the fuel consumption and operating costs. So the Process unit system efficiency evaluation is a crucial point. ChromEnergy was used for electrical gas power plant application to monitor gas quality and check performances ration before and after the process.

ChromEnergy from the Chromatotec (France) product line is part of solution provided for Oil & Gas market. Where energyMEDOR is more focused on Sulphurs monitoring and odourisation, application, the chromEnergy gas analyser designed for the measurement of hydrocarbons.

Using a Thermal Conductivity Detector (TCD), this automatic gas chromatograph analyser is the perfect tool to detect and quantify hydrocarbons from C1 to C6+. This equipment works with isothermal mode. Coupled with the last version of Chromatotec’s software (Vistachrom), the instrument is able to provide calorific value and WOBBE index to the end user on automatic mode.

With its high sensitivity and robustness, the analyser is a perfect instrument for natural gas characterisation. The chromatograms mentioned hereafter illustrates its capabilities to quantify the hydrocarbons as iso- or linear propane, butane, pentane (iso and linear) or hexane. When

In term of functions, end user has defined some individual alarms per type of molecule. Thanks to software capabilities, C1C6+ group has been created as additive parameter to check global profile and be warned when significant changes of concentration are observed. Thanks to the embedded PC and Modbus data transfer protocol, user check results from dedicated Supervision center offering results at a glance. The 4-20 mA output option allows to adjust the process by direct integration of the signal on the process.

Combined with energyMEDOR, Chromatotec offers a very competitive & efficient solution for hazardous areas for energy and oil& gas market applications in any type of environment.
