Choose the Right Heat Transfer Fluid Consider a variety of factors to ensure effective and enduring performance

摘要

THE ROLE of a heat transfer fluid (HTF) is simple - to transmit heat to a process stream. However, selecting a high-temperature HTF to use in a new operation isn't a simple task for a non-specialist. Here, we'll address some of the common conundrums that every company will face and provide some practical pointers. HTFs generally are mineral or synthetic; it's very common to compare the relative characteristics of these fluids. However, this comparison really only makes sense in two scenarios - during the design of a new facility or when planning to completely replace an aged fluid with a virgin HTF. In most cases, the key consideration is effectively maintaining an existing system to ensure the plant operates as efficiently as possible and the HTF achieves a long working life (Figure 1).
