Process Combustion have designed and supplied a thermal oxidiser, boiler and gas clean-up system for the £6 million thermal energy plant at Scottish Leather Group’s manufacturing site at Bridge of Weir, Glasgow, Scotland. Scottish Leather is a high quality, specialist supplier to the interior and transportation seating industries.
The system supplied by Process Combustion consists of a thermal oxidiser, waste heat boiler, ceramic filter plant, induced draught fan, SCR based NOx suppression unit and a chimney as well as other ancilliary equipment. The thermal oxidiser burns syngas supplied from a gasification process and tallow or natural gas.
Process Combustion also supplied an integrated control system which includes all safety systems and process control. The plant was designed in compliance with the requirements of WID and of the operating permit issued by SEPA.
The plant is the first in the world in the leather industry, leading the way in low-carbon manufacturing. The new plant can process 30,000 tonnes of waste generated by the site each year at a rate of 100 tonnes per day. The waste which previously went to landfill is turned into heat and steam, up to 8200kg/hr, for drying leather and heating water.
