Abstract
The invention comprises an absorption heat pump to supply energy to a distillation process or an outside process. The streams used to effect the absorption heat pump are to be combined in any case as a feedstream to a conversion process, and energy thus is conserved by avoiding the necessity of reseparating the streams.
Claims20
A separation process comprising an absorption heat pump by dividing a feedstream into at least one lower-boiling vapor stream, at least one intermediate product, and at least one higher-boiling liquid stream and recombining at least one each of the lower-boiling and higher-boiling streams to obtain an enhanced heat source and feedstock to a conversion-process, comprising:
- a. absorbing the at least one lower-boiling vapor stream in at least one higher-boiling liquid stream to obtain an enhanced heat source;
- b. supplying heat to an energy-absorbing process from the enhanced heat source thus deriving a conversion-process feedstock from the heat source;
- and,
- c. processing the feedstock without further separation in a conversion process.
A distillation process comprising an absorption heat pump by dividing a feedstream into at least one lower-boiling vapor stream, at least one intermediate product, and at least one higher-boiling liquid stream and recombining at least one each of the lower-boiling and higher-boiling streams to obtain an enhanced heat source and feedstock to a conversion-process, comprising:
- a. absorbing the at least one lower-boiling vapor stream in at least one higher-boiling liquid stream to obtain an enhanced heat source to effect separation of the feedstream;
- b. supplying heat to the separation process from the enhanced heat source thus deriving a conversion-process feedstock from the heat source;
- and,
- c. processing the feedstock without further separation in a conversion process.
A distillation process comprising an absorption heat pump by dividing a feedstream into a lower-boiling liquid stream, an intermediate product, and a higher-boiling liquid stream and recombining the lower-boiling and higher-boiling streams to obtain an enhanced heat source and feedstock to a conversion-process, comprising:
- a. vaporizing the lower-boiling liquid stream using a low-temperature fluid to obtain a lower-boiling vapor stream;
- b. absorbing the lower-boiling vapor stream in the higher-boiling liquid stream to obtain an enhanced heat source to effect separation of the feedstream;
- c. supplying heat to the separation process from the enhanced heat source thus deriving a conversion-process feedstock from the heat source;
- and,
- d. processing the feedstock without further separation in a conversion process.
