8.3% fuel saved annually through condensate recovery at a rice noodle and flour processor in Thailand

A rice noodle and flour processing plant in Nakhon Pathom, Thailand was not recovering condensate or flash steam due to an inoperational tank and electrical pump based conventional condensate recovery system. Forbes Marshall conducted a plant survey and recommended solutions to improve condensate recovery.

Objective

PROBLEM

The existing conventional condensate recovery system was designed based on a condensate collection tank and electrical pump. Condensate was being drained locally and flash steam was being vented. Boiler feedwater temperature was 30°C (86°F) and feedwater consumption was high. There was no live steam being used in the deaerator head.

Solution

SOLUTION

Forbes Marshall conducted a plant survey to assess the condensate recovery network. We recommended replacing the existing condensate tank and electrical pump setup with a FlashJet™ Pump (FJP). After installation, the plant recovered 100% flash steam and condensate to the feedwater tank.

Benefit

BENEFITS

8.3% fuel saved annually

Feedwater temperature increased from 30 to 80°C (86 to 176°F)

60 Tonnes (132K Pounds) condensate recovered per day

4.6 Tonnes (10K Pounds) flash steam recovered per day

18,000 Kilolitres (4755K Gallons) of water saved annually

343,030 kcal (1.36 million Btu) heat energy recovered per hour

49 Tonnes (108K Pounds) of CO₂e reduced annually

Annual monetary savings of THB 3,355,042 (~USD 97,690 *converted based on exchange rate)
