207 Kilograms (59 Gallons) of furnace oil fuel saved daily for a Beverage MNC in Thailand

During our assessment we observed the Pateuriser Hot Fill line 3 was using float traps, which were experiencing condensate stalling due to low process temperatures. Due to stalling the operator was keeping the trap bypass valve open, draining condensate locally.

Additionally, the condensate line was lifted to a 5 meter height and recovery was by trap pressure. This further increased the backpressure on the float traps.

Steam was being supplied at 5-6 barg and the PID control valve had to be manually opened to 100% to maintain targeted product temperature of 97°C (206.6°F).

Issues of leakage detected in two of the three plate heat exchangers (PHEs).

Forbes Marshall conducted trials at Pasteuriser Hot Fill line 3. The following solutions were recommended and implemented:

• 3 steam operated pumping traps (SOPT) at PHE 1, 2 & 3 were installed to address the issue of condensate logging seen when using a float trap
• 2 steam operated pressure powered pumps (PPPPU) with a condensate recovery meter (CRM) were installed to recover condensate to the feedwater tank
