Optical cells for in-line monitoring

SITEC High pressure equipment for inline monitoring of concentrations in supercritical and high pressure and temperature processes

Specifications
Pressure max. 1.000 bar
Temperature max. 180 °C

Features and advantages

Combining a high pressure optical cell, a fiber-optic interface and a NIR-spectrophotometer allows the in-line monitoring of concentrations in high pressure and high temperature processes In production plants for supercritical extraction for instance such an in-line monitoring sytem allows to stop the extraction process at the optimal time and therefore to operate the plant more efficiently. the additional information earned from the in-line monitoring allows a faster process optimization. For chemical reactions in supercritical CO2, the data for kinetic modeling can be determined and existing reaction processes can be optimized. The sophisticated design of the high pressure optical cell allows the adaption of the optical path length to the components to be detected and the concentration range High pressure optical cells for NI in-line monitoring are available for max. operating conditions up to 1.000 bar and 180 °C. Customer requirements are considered. Fluid contacted parts are offered in stainless steel AISI 316Ti, 17-4 PH, AISI 660 or in special materials like Hastelloy, Inconel, etc depending on operating conditions Heating is realized with a electrical heating jacket or double wall for fluid heating. The fiber-optic interface is specially adapted to the SITEC window units The investigation of the feasibility and also the application engineering will be quoted and performed by our cooperation partner, the Karlsruhe Institute of Technology
