Multistream Gas Analysis Solutions From Twin-Tek

15th April 2021

Protea’s FTIR, TDL and QMS analysers are available with measurement from multiple sample points using standard modular equipment for cost-effective bespoke solutions.

A multiple sample point or multistream solution can enable cost savings by allowing one emissions analyser to make sequential measurements from many different sample points. Multistream systems from Protea use tried and proven components and features. The modular aspect of our designs means a multistream solution can begin with a low number of points and additional pieces of hardware added in time to build an expanded solution in the future.

• Inlet and Outlet for emission abatement efficiency
• Multi-stack CEMs with standby systems
• High dust CEMs with dual sample system switchover

Multistream Benefits

• Separate analyser calibration file for each sample point
• A different set of gases and ranges can be measured from each sample point so one FTIR can do the job of hundreds of sensors
• Separate configuration file for each sample point
• Variable measurement times configured for each stream, some points can be quick measurements (2-5 seconds), some longer (1-2 minutes)
• Pauses can be configured in the sequence, to allow gases to condition in the sampling system and the analyser
• By-pass pump can be provided and controlled by the software. This allows non-sampled positions to be flushed with sample ready for measurement, ensuring quick response time
• Span gas checks per stream, allowing each point to have response time and to check for leaks
• Heated multiple sample point systems available up to 12 streams, with 12 heated probe alarms and 12 heated line alarms with heated valve manifolds
• Sequence easily built in PAS-Pro software – no programming or PLC programme updating needed
• Separate log file for data for each stream - easy for operator to sort data and report values
• Separate OPC and Modbus data outputs for each stream
