from plant is designed for a peak heat recovery of some 317 kW , although initially only 200 kW will be recoverable due to the plant capacity ramping up over the life of the facility . The hot compressor oil from the discharge side is used to heat a closed loop hot water circuit from 47 ° C to 63 ° C . This is then pumped via a hotwell to the crate washer to heat the crate washer water . Provision for a future heat pump , utilising the discharge gas from the primary ammonia plant and compressing it to 70 ° C saturated conditions in order to generate hot water in future if required .
The plant has been equipped with VSD on all major component motors to ensure that part load conditions are optimised and energy savings are being realised during part loads conditions .
High efficiency EC fans were specified for the cold room . Due to there being a total of 104 blower coils and 416 fans with a total peak power consumption of 650 kW , it was very important to optimise the fan speed and control to reduce power consumption to an absolute minimum .
Due to safety , and as a result of the size of the facility , the decision was taken early on in the design
