Prior to our first cleaning service, fouling had never been correctly removed, and built up year-on-year leading to the fans recirculating air at the inlet.
The site’s hydroquinone condenser was struggling at higher ambient temperatures during summertime, this created a process bottleneck at the column, reducing the potential production flowrate. The cleaning service covered the two AFC units across the HQPC Plant, starting in early June and ending in early July.

The ambient air was at 32-34°C daily.

Once the unit was cleaned the outlet temperature was reduced by 6°C, even during peak summertime temperatures.
