Turnkey small-scale plants involving tanks, pumps, piping systems, steam supply, vacuum raising, scrubbers, instrumentation and electrics.

Plant optimisation and debottlenecking of all of the above.

Applications – Some recent projects:

Stillage MVR Evaporation plant

Water recovery of 225m3/hr utilising mechanical vapour compression type evaporators. The concentrate is then dried to produce animal feed.

MVR Evaporation can be applied to a wide range of evaporation duties including waste waters, brine liquors and many salt solutions. These evaporators can be configured to use as little as 12kW/m3 of evaporated water. Little cooling water is required and typically, steam is only used for start-up. In many cases the MVR evaporator can be followed by a crystallisation and/or a dryer unit for zero liquid discharge.

Thermocompressor and ejector systems From Transvac (http://www.transvac.co.uk) for evaporator plants and other processes.

Thermocompressors can be used in many heat recovery processes including the recovery of vented steam and the integrated steam/cooling water systems. Ejectors/Eductors can be used for tank heaters, tank mixing and pumping solids amongst many other applications.
