תיאור
The instrument can function as:
High-performance closed-cell adiabatic calorimeter
High-temperature and high-pressure reaction calorimeter
Open test cell from which effluent can be discharged and analyzed for emergency relief system studies using the DIERS methodology of the American Institute of Chemical Engineers
The precision and accuracy of APTAC® 264 test results help companies in scaling up process designs to production scale by:
Providing actual temperature and pressure data for use in kinetic modeling
Validating predicted chemical reactions and scenarios
Confirming predicted events following the activation of an emergency relief system
Directly measuring physical property data of complex mixtures
APTAC® 264 can be used for the thermal analysis of solid or liquid chemicals or for gas/liquid, liquid/liquid, gas/solid, and liquid/solid mixtures. It can also be used for process simulation of batch and semi-batch reactions, fire exposures, emergency relief venting, and physical properties measurement.
It offers a new degree of accuracy in reactivity data for chemical manufacturing industries, including organic chemicals, petrochemicals, pharmaceuticals, agrochemicals, fine organics, polymers and plastics, and explosive highenergy materials.
