Automated measurement of critical chemical process parameters to boost plant performance
Laser-based measurement technologies like Raman spectroscopy and tunable diode laser absorption spectroscopy (TDLAS), continue to gain traction over alternative methods like gas chromatography or mass spectrometry. With no moving parts, and greatly reduced need for sampling, the used process analyzers are easier to maintain, and provide highly precise results within seconds. This enables smarter control of rapidly changing processes in real-time, without human exposure to hazardous chemicals.

Applications
Reaction endpoint detection and kinetics control
Emulsion polymerization produces a wide range of polymeric materials, including paints, adhesives and synthetic rubbers. This type of reaction is performed within an aqueous environment where the monomer species is maintained within a single phase with a suitable surfactant or emulsifier. One or more monomer species may be used, and the resultant polymer or copolymer is produced as a stable suspension, in the form of a latex.
Chuyên môn của chúng tôi trong lĩnh vực
Raman spectroscopy is well suited for monitoring these reactions insofar as it is sensitive to the measurement of specific double bonds, and it does not suffer with interference from the aqueous matrix.
Band ratios can compensate for variations in overall measured intensity of the reaction
Water does not interfere with measurement in aqueous solutions
Ability to measure through glass reactor walls or windows
Excellent correlation with chromatographic and gravimetric data
Costs of a plant shutdown due to off-spec gas can be very high especially for petrochemical processes.
Chuyên môn của chúng tôi trong lĩnh vực
TDLAS analyzers monitor the quality of feed gases by selectively measuring contaminants such as ammonia (NH3), moisture (H2O) or acetylene (C2H2). These measurements help improve process control, meet product specifications, prevent catalyst poisoning and minimize flaring. The analyzers provide reliable measurements within seconds, thus enabling quick actions. We provide complete analyzer solutions comprising of a sample extraction and conditioning system and suitable analyzer enclosures.
In-line monitoring of product properties and quality
Polymerization reactions are often done in semi-batch mode. This allows for careful control of product composition in order to create high-performance materials with finely tuned custom properties. During the reaction, strict control over the reactant concentrations is necessary to avoid unwanted properties in the end-product. Simply adding the reactants in the correct ratio is insufficient.

Our Raman analyzers are sensitive to specific functional groups, such as the vinyl and alkyl moieties common to polymerization monomers. Our easy sample interface and its fiber optic coupling to the base unit allows for flexible placement of the base unit relative to the batch reactors or process lines.
Options available for non-contact optics allowing measurement through reactor windows
Measure up to four batch reactors or process streams with a single analyzer
Deliver consistency between batches with respect to average molecular weight and polydispersity
