850 Kilograms steam saved daily at the Sugar Syrup Section for a confectionery MNC in Thailand

A confectionery MNC was facing multiple issues in their sugar syrup section having two tanks:

• Due to a malfunctioning precise temperature control system, the temperature was overshooting up to 95°C (203°F), exceeding the set point of 85°C (203°F), resulting in a 10°C (50°F) deviation. This brought the product temperature to boiling, resulting in vaporisation and overflow of product from the tanks.
• A lack of pressure reduction led to high pressure steam being supplied to the sugar syrup tanks.
• Waterlogged or subcooled condensate was also getting accumulated due to use of float traps, resulting in water hammering.

Forbes Marshall recommended and implemented the following solutions in the sugar syrup section:

• A PID temperature control valve was installed for effective temperature control and safe operations.
• Float traps were replaced with Steam-operated pump traps (SOPT) to evacuate waterlogged and subcooled condensate.
• A Vacuum Breaker (FMVB) was installed on the jacketed vessel as a safety measure.
• A Moisture Separator (FMSEP) was installed to improve steam quality by removing entrained moisture.

Temperature was controlled within +/- 1°C (+/- 33.8°F) of the set point

Steam savings of 70 Kilograms (154 Pounds) per batch, totalling 850 Kilograms (1,874 Pounds) per day for two tanks

Annual monetary savings of USD 4,000 (~THB 128,920 *converted based on exchange rates) for two tanks
