Prepare a mass balance to identify where the greatest losses are occurring and thus the potential for improvement.
Real improvements in solvent performance and cost reductions are made only if staff operate and maintain the equipment correctly.
Reducing solvent use in your operations will lead to less spent solvent waste requiring disposal, fewer VOC emissions requiring abatement and a reduced risk of pollution.
Flow restrictors on vessel cooling lines can reduce water use by 5%.
Trials have shown that the re-use of wash water for batch dilution can reduce water consumption by 25%.
Monitoring water consumption and effluent volumes is essential to control and reduce costs. Where possible, fit sub-meters to monitor consumption for each production area. Check water use during ‘silent’ periods, such as overnight and during shutdowns. If it is not close to zero, find out why, there may be a leak or plant left running unnecessarily.
