Definitions

  • step (c) the flow of liquid desiccant 7 is sent through a heat exchanger El, to the distillation column D1 of the regeneration device R1, which further comprises a reboiler R2; from said regeneration device R1, it leaves a vapor effluent 8 containing water and BTEX at the top and a liquid effluent 3 at the bottom, constituting the regenerated liquid desiccant, which is sent through the heat exchanger El and the pump P1, at the head of the absorption column A1 of step (a).
  • the temperature in the reboiling zone R2 is generally between 150 ° C and 250 ° C.
  • the gaseous effluent leaving column L1 via line 14 is freed from the BTEX fraction but is also dehydrated. It can therefore be recompressed by a compressor K1 and mixed with the treated gas as indicated in the diagram in Figure 4.
  • a compressor K1 can be associated with the effluent 14. This can thus improve the production yield of the treated gas, which constitutes an additional advantage of the process .
  • Said effluent 14 can also be used as fuel for heating the reboiler R2 of the regeneration system R1.
