HICOSYS 
ADVANCED

The Hobré HICOSYS is the first to combine H₂O and CO as two measuring components in one analyser. Enabled with multiple sample points, the HICOSYS is an exceedingly flexible instrument that can be fitted at all types of spray dryer installations. It sequentially measures up to eight sample points with a fast response of only 10 – 15 seconds per sample. CO and H2O in absolute humidity are measured simultaneously.

HICOSYS offers outstanding measurement of these parameters, making it possible for powder producers worldwide to either use one or both measuring components with only one instrument. The combination provides better control of powder sedimentation and further reduces smouldering.

The drivers for carbon monoxide (CO) and moisture (H₂O) analysis

Safety

Coagulation and lump formation in processed product, caused by undesired and uncontrolled process conditions, pose a large risk to the dryer’s operation and shorten production cycles between cleaning. Moreover, coagulated product is exposed to increased residence times, causing undesired and degenerating smouldering reactions which create a significant risk of fire and explosion. CO detection, as a pre-warning, is widely used as a dryer installation’s safety system.

Efficiency

Humidity is one of the most important parameters which can be used in maximizing the efficiency of spray drying operations. Measurement of absolute humidity at elevated temperatures and high dust loads – in an accurate and reliable way – has always been a challenge for end-users. RH Capacitive and dew point measurement technology has proven to be inaccurate and unreliable for these challenging applications. In addition, soft sensors (material balance, flow, density) calculation of H2O depends on too many parameters and is often considered to be imprecise.

With our proprietary probes, the HICOSYS ADVANCED is capable of measurement at the most challenging locations such as the tower exhaust, even before filtration by cyclones and/or bag filters.
