Case Study #1
Dickinson Legg
Process Combustion installed a thermal oxidiser and process heater unit for Dickinson Legg, a designer and manufacturer of primary tobacco processing machinery and plant.
The thermal oxidiser and process heater unit was specified for the manufacture of part of the tobacco drying machinery. The thermal oxidiser provides heat into the drying loop using a recycle heat exchanger. An exhaust stream from the drying loop is supplied to the thermal oxidiser, where it reaches a temperature of about 800°C to oxidise contaminents. Waste heat is also recovered.
The equipment supplied by Process Combustion included a thermal oxidiser chamber lined with ceramic fibre blocks; a dual fuel burner; fans; fuel gas and oil trains; a recycle gas heat exchanger and a waste gas pre-heater; duct-work; a skid base frame; and a burner management system.
It is the company's twentieth thermal oxidiser and process heater unit installation. Process Combustion has supplied systems to China, Indonesia, Vietnam, South Korea, Turkey and Chile over a 14-year period.
Case Study #2
Scottish Leather Group
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 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.
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.
