SUSHEAT system
to be validated

at Pelagia

The SUSHEAT technologies will be validated by using real-time and simulated data from Pelagia’s fish meal and oil processing plants. Enerin’s HoegTemp High-Temperature Heat Pump (HT-HP) will be installed to test the heat pump’s temperature lift and temperature input/output variability. The Pelagia factories produce ingredients that are used in animal feed, mainly for the aquaculture industry.  

Currently, the Pelagia manufacturing plants use fossil-fired steam boilers that produce steam (175° Celsius), which heats the cookers and dryers that are used for general processing, and to produce heat for the final stages of product drying (200–250°C).  The SUSHEAT technological solutions must be capable of receiving waste heat across the temperature range of 60–90°C and deliver it across a range of 150–250°C.

The system will target heat delivery across this entire temperature range with flexibility to produce heat at different temperatures according to the plant demand profile. Recovering waste heat from the processes will be available from two sources: the humid air dryers and in condensate streams, both of which will present a significant challenge.

Successful validation will be a major technical innovation in industrial heat pumps in terms of temperature lift and temperature input/output variability. The ambition for Pelagia’s involvement in SUSHEAT is to reduce global Greenhouse Gas (GHG) emissions and the company’s associated costs by optimising profitability through lowering the energy input for processing.

SUSHEATwill validate:

Energy/steam output from the HoegTemp HT-HP system;

The Co-efficient of Performance (COP) of the HT-HP;

The reduction of fossil fuel usage and GHG emissions;

Electricity usage; and 

Energy consumption per unit raw material processed (proprietary information).

The targetedbenefits:

Energy efficiency — Pelagia aims to achieve a lower energy input for each unit of produced product because the COP of the heat pumps are significantly higher than for steam boilers.
 
Environmental sustainability — Pelagia aims to decrease its GHG emissions at the factory.
 
Cost savings — The company expects the highest savings to be related to the reduced amount of CO2 quotas it needs to buy to offset current emissions.
 
Process optimisation — Heat pumps are not as flexible as steam boilers, given their dependence on an external heat sources. This will demand more attention from the process operators, but will also force the company to be more proactive in how the equipment in the factory is run.
