Several well-known chemical processes use Therminol heat transfer fluids as a heating medium. LAB (linear alkyl benzene), phthalic anhydride (PA), terephthalic acid (PTA), dimethyl terphthalate (DMT), olefins, alcohols, plasticizers and a variety of other petrochemicals have heat transfer systems as an integral part of their processes. A central heating and circulating system with multiple users provides temperature control for different stages in the reaction, separation and purification of the various products. The chemical industry around the world has relied on Therminol liquid phase heat transfer fluids and vapor phase heat transfer fluids to provide long-term, trouble-free performance in heat transfer systems that are critical to the success of their operations.
The family of Therminol heat transfer fluids has products that will meet the requirements of nearly any chemical process. Liquid phase heat transfer fluids such as Therminol 55, Therminol 59, Therminol 66, and liquid or vapor phase heat transfer fluids such as Therminol VP-1 and Therminol VP-3 are the fluids most commonly used in the chemical process industry. Each chemical process has different operating parameters that can be used by a design or process engineer to select the heat transfer fluid that will result in the best total performance. Therminol 55 is usually used when only moderate temperatures are required. Therminol 59 is best when heating/cooling applications are needed. Therminol 66 (liquid phase heat transfer fluid), Therminol VP-1, and Therminol VP-3 vapor phase heat transfer fluids, are preferred when high operating temperatures are required. In every case, there is a Therminol heat transfer fluid that will achieve the required performance.
