This week's Chemical E-Book topic highlight is: Boilers & Turbine Engines 

Chemical processes can produce a uniform synthetic gas (syngas) that is used to power turbine engines.

In order to optimize engine performance, the total calorific value of the syngas must be measured.

For a more detailed look at this application, check out this case history:

A developer and producer of advanced fuels and green chemicals used a gasification process to break down wood chips, waste and other feedstock using plasma technology. The process produces a syngas that powered their turbine engines, they were measuring the total calorific value to optimize its performance.

They were using a gas chromatograph to take the measurements but this could only give readings for low chain hydrocarbons and measurement in batch-mode, not high carbon chain molecules. As a result they had to make time-consuming calculations to include all of these unknowns, which led to operating the engines for worst case and not optimum efficiency. This process needed to change.

  • The CalorVal BTU analyzer was the analyzer of choice because it completely burns the syngas sample and therefore is a direct measure of the total calorific value. It accurately reads the varying compositions and concentrations of all the gases in the syngas stream. Since this analyzer reads continuously, it measures in real-time mode to provide dynamic control of the engine.
