Energy Efficient Regeneration Process
The present invention relates to a novel energy efficient multi-stage regenerator, for regenerating liquid desiccant (LD), and further relates to the application of rotating contacting disks to provide intimate contact between LD and vapour/gas without problems of carryover of LD in to the vapour/gas stream or flooding and suitable for low liquid throughputs, with significant change in concentration. -An energy efficient multi-stage regeneration process (EEMSRP) along with components for regenerating liquid desiccant (LD) comprising partial or complete regeneration of LD in a Low Temperature Regenerator (LTR), partial or complete regeneration of LD in a Intermediatg Temperature Regenerator (ITR), partial or complete regeneration of LD in a High Temperature Regenerator (HTR), desuperheating of vapour generated in HTR in a heat exchanger (HTRHE) while preheating the LD before entering HTR, subcooling of LD regenerated in HTR in HTRHE while preheating the LD before entering HTR, condensation of desuperheated vapour from HTRHE in heat exchanger inside ITR while regenerating LD, desuperheating of vapour generated in ITR in a heat exchanger (ITRHE) while preheating the LD before entering ITR and/or HTR, subcooling of LD regenerated in ITR in ITRHE while preheating the LD before entering ITR and/or HTR, subcooting of condensate from ITR in ITRHE while preheating the LD before entering ITR and/or HTR, desuperheating of vapour generated in ITR in a ITRHE while preheating the LD before entering ITR and/or HTR, condensation of desuperheated vapour from ITRHE in "passages" thermally in contact with LTR while regenerating LD, flowing of vapour/gas through LTR with the aid of and arrangement such as chimney/fan to pickup the vapours from LD, subcooling of LD regenerated in LTR in LTRHE while preheating the LD before entering LTR and/or ITR and/or HTR, subcooling of condensate from LTR in LTRHE while preheating the LD before entering LTR and/or ITR and/or HTR, wherein the number of stages in the regeneration process is (2+n) where n is the number of ITR"s in the process. A system for energy efficient single stage regeneration process and components for regenerating liquid desiccant (LD) comprising LTR, incorporating large surface density contacting device, having provision to heat the LD using heat from an external source in passages which are in thermal contact with a container such as a trough containing the LTR, optional arrangement such as a hood with chimney to aid the flow of ambient air through LTR to pickup the moisture from LD, a device to rotate/oscillate the contacting discs assembly in the LTR, optional heat exchanger used to recycle heat to enhance the energy efficiency of the process and liquid desiccant pump. The main advantages of energy efficient multi-stage regeneration of LD are no carryover problem, no orifices or nozzles to wear or clog, modular system that can be installed with flexibility, silent operation without splashing or spraying sounds and low auxiliary electrical power consumption.
