Safety control of raw materials
Melamin’s use of Raman analysis for identification of chemicals
Melamin partnered with Endress+Hauser to screen solvents fed into raw material tanks for resin production. By implementing advanced process analytical technology, Melamin can achieve its primary business objective: increased operational safety while enabling high plant performance. Raman inline measurement is replacing offline lab identification of chemicals before the material is transferred from the truck to storage tanks, eliminating time-consuming handling and potential human error.
Benefits:
-
Increased operational safety while enabling high plant performance
-
Elimination of time-consuming handling and potential human error
Endress+Hauser’s process control instrumentation has enhanced our plant performance. Raman spectroscopy ensures the secure and accurate transfer of solvents from trucks to the correct tanks.

Challenge
Mixing different kinds of chemicals could cause contamination or exothermal reactions due to incompatibility, potentially leading to an explosion. Therefore, it is crucial to automate the identification of incoming materials to prevent the mixing of immiscible chemicals.
Our solution
Melamin partnered with Endress+Hauser to screen solvents fed into raw material tanks for resin production:
The temperature of the chemical is monitored using an iTHERM ModuLine TM131 sensor
A Liquiphant FTL50 point level switch then triggers the Raman spectroscopy analysis once the pipe is confirmed to be filled with the chemical
A Raman Rxn2-785 nm analyzer with four channels was installed in a control room for ATEX areas
Raman Rxn-40 probes are installed inline at the truck unloading station
