The HRS unit utilises two K Series multi-pass corrugated tube heat exchangers to maintain solvent temperature at 25 ° C or 30 ° C as required . The hot water loop is composed of one heat exchanger , a centrifugal pump , safety features , and the necessary ancillaries such as a pressure gauge , temperature transmitter and manual valves . “ The service water is recirculated in a closed loop with the selected solution tank to heat the solvent from 15 ° C to the target temperature ,” says Ella Taghavi , Technical Sales Engineer at HRS Heat Exchangers . “ The process is controlled by temperature transmitters and an autonomous control system and given the importance of the temperature in the process ; product temperature is also monitored via a secondary control loop with transmitters located on each solution tank .” Moreover , the cooling section is designed to maintain the product temperature at the targeted set point . Incoming service water from a buffer tank is cooled using chilled water at 6-10 ° C from elsewhere in the factory using several passes through the second heat exchanger . “ The tank jacket service water is recirculated in a closed loop with the selected solution tank to cool the solvent from 40 ° C to the target set temperature of 25 ° C or 30 ° C ,” adds Ella . Again , temperature transmitters control the process via an autonomous control loop .
Smooth operation Despite the Covid-19 pandemic , the process of manufacturing , installing and commissioning the unit ran smoothly , taking less than six months from the order being received to the unit being fully operational . “ Covid-19 meant that we weren ’ t able to undertake Factory Acceptance Testing ( FAT ) at HRS ’ s manufacturing facility in Spain , but as it was such a straightforward job , we wouldn ’ t have insisted on this anyway ,” said the spokesperson . “ We undertook the commissioning on site with remote support from HRS ’ s Engineer Ella Taghavi in Melbourne , but apart from a couple of phone calls nothing else was required .”
