Process Equipment Update
such as hardness and dissolved Oxygen before it can be used, otherwise the water will cause scaling and corrosion which can very quickly lead to equipment failure. Advances have been made in developing more environmentally friendly water treatment processes but these are not in widespread use and inevitably cost more.
and some are food grade fluids which are approved for incidental contact with food. Most thermal fluids tend to have a very long life - often more than ten years, depending on the temperature of operation, how close it is to maximum bulk range and the number of thermal cycles. Furthermore, the fluids are generally recyclable in the case of oils, whilst most of the specialist fluids can be re processed so end of life requirements are easily managed. But the most notable environmental contributions a
thermal fluid heating system has over its rivals comes from the overall substantial energy savings achieved and the subsequent reduction in overall emissions from the system. Thermal fluid heating systems are closed circuit, no-loss systems which results in minimal heat loss. When compared with a steam system this means no change of state of the fluid so no condensate and therefore no flash steam losses also no blow down losses or make up water are required. Plus, because it is a closed loop system where pressure is not related to temperature, they are able to economically work at high temperatures (up to 350°C in standard form). It all adds up to substantial savings for the user. With Babcock Wanson’s TPC1000B thermal fluid heating

On the other hand there are a wide range of thermal fluids available which act as excellent heat transfer mediums. The majority are industrial grade mineral oils, some are synthetic,
system, for example, between 20-50 per cent energy savings can be made when compared to the transfer of the same amount of heat using traditional steam boilers. The system precisely matches fuel input to plant energy requirements for high efficiency. Of course, the less you have to fire the burner and the
lower energy input demand, the lower mass flow of pollutants get discharged to the atmosphere, so there are important
