London-based HRS Heat Exchangers has signed a $1.8 million contract
with Scottish and Southern Energy to deliver a scraped surface vacuum
evaporator for SSE's Barkip anaerobic digestion plant in North Ayrshire. The
HRS self-cleaning evaporator system overcomes the fouling issues associated with
the evaporation of organic digestate, says the company.
The Barkip plant will be the first of its kind to
incorporate a novel digestate processing stage: Waste heat from the combined
heat and process (CHP) engines is used to concentrate the liquid fraction of
the digestate into a nutrient rich liquid fertilizer. Under the terms of the
contract, the HRS technology will enable the Barkip Anaerobic Digestion plant
to process 82.6 short tons of waste annually in a plant setup that produces
around 2.5 MW of renewable electricity.
HRS’ scraped surface heat exchanger will be used to help
ensure any high organic load in contact with hot surfaces does not lead to
fouling. Its Unicus Dynamic technology provides continuous cleaning to the
walls of the HRS evaporator. The project was co-developed by Zebec Biogas,
which has the specialist enzyme and biological process expertise.
