Technologies in the coal chemical industry such as tar fractionation, benzol hydrogenation, anthraquinone production, device reaction and distillation, and rectification devices have a relatively high requirement for temperature regulation. Because heat transfer fluids are characterized by low operating pressure, high thermal efficiency, even and stable heating, and a wide range of temperature control, these precise technological requirements can be met completely. Meanwhile, the waste heat can be recycled to save energy, reduce pollution, and reduce production cost.
