Process Diagnostics with gamma rays at destillation columns, for Troubleshooting and predictive maintenance. We visualise your column performance during operation to increase product quality and throughput. The online measurement at your column identifies the fluiddynamik and mechanical situation of the column internals. We offer our services in Europe within one week notice. Our measurement results are available the next day after our measurement. We identify fouling and two phase flow in pipings. We measure packed reactors to visualise mal distribution. We measure heat exchangers to visualise fouling and liquid levels.
