Davidson Clark Ltd

Design and supply of all types of gas cleaning systems including spray towers, packed towers, venturi, and plate scrubbers incorporating the patented Davidson Clark scrubbing plate which offers higher capacity and efficiency compared to other designs. Recent applications include sodium and hydrogen cyanide, dryer exhaust gases, lead oxide, acid fumes, plasma cleaning exhaust gases, gas cooling, high pressure saturation, peat smoke, ammonia, VOCs, phenoxy acids. Design and supply of heat transfer systems. Emission monitoring to the requirements of the Environmental Protection Act 1990, all gaseous contaminants and particulate monitoring. In situ measurement of the particle size of smoke and fumes which is essential knowledge for the design of gas cleaning plant. Infra-red thermal surveys to check plant operation efficiency. Pilot plant available for research/demonstration purposes.

The photographs show part of a whisky by-products plant located in northern Scotland.  The 'BEFORE' chimney shows the emission from one of the plants prior to installing the DAVIDSON CLARK gas cleaning system.   The 'AFTER' chimney shows the emission from the other plant which has been fitted with the DAVIDSON CLARK system.

The emissions come from a drying process handling pot ale and wet draff, residual materials from the production of malt whisky.   These are converted into animal feeds, and the dryer exhaust gases contain small grain particles, oil droplets and vapour phase contaminants.   The DAVIDSON CLARK LTD scrubbing system simultaneously removes all three with a high degree of efficiency.

The design of the system is based on our own in-situ particle size measurements of the grain fines and oil droplets, followed by extensive pilot plant trials.
