Abstract
A synthetic aromatic heat transfer fluid regenerating assembly is disclosed. The synthetic aromatic heat transfer fluid regenerating assembly heat transfer fluid regenerating assembly of the present invention includes (a) a fluid connector for fluidly connecting the synthetic aromatic heat transfer fluid regenerating assembly to a heat transfer system that includes contaminated synthetic aromatic heat transfer fluid contained in a heat transfer loop; and (b) a divided wall distillation column fluidly connected to the fluid connector and including a side-draw outlet. A related heat transfer assembly and a method for regenerating contaminated synthetic aromatic heat transfer fluid from a heat transfer system are also described.
Claims19
A method for regenerating contaminated synthetic aromatic heat transfer fluid from a heat transfer system comprising contaminated synthetic aromatic heat transfer fluid contained in a heat transfer loop, said method comprising the steps of (a) diverting at least a portion of said contaminated synthetic aromatic heat transfer fluid from said heat transfer system to form a feed stream comprising contaminated synthetic aromatic heat transfer fluid;
- and (b) passing said feed stream comprising diverted contaminated synthetic aromatic heat transfer fluid into a synthetic aromatic heat transfer fluid regenerating assembly, said synthetic aromatic heat transfer fluid regenerating assembly comprising a divided wall distillation column, to form a side draw stream, a low boiler distillate stream and high boiler distillate stream.
A synthetic aromatic heat transfer fluid regenerating assembly, said assembly comprising (a) a fluid connector for fluidly connecting said synthetic aromatic heat transfer fluid regenerating assembly to a heat transfer system, said system comprising contaminated synthetic aromatic heat transfer fluid contained in a heat transfer loop;
- and (b) a divided wall distillation column fluidly connected to said fluid connector and comprising a side-draw outlet.
A heat transfer assembly, said assembly comprising (a) a heat transfer system comprising contaminated synthetic aromatic heat transfer fluid contained in a heat transfer loop;
- and (b) a synthetic aromatic heat transfer fluid regenerating assembly fluidly connected to said heat transfer system;
- wherein said heat transfer fluid regenerating assembly comprises a divided wall distillation column.
