PROCESS FOR TREATING A LOADED SOLVENT STREAM HAVING A TIME-VARYING CONCENTRATION OF CONTAMINANT

摘要

The invention provides a process for treating a loaded solvent stream having atime-varying contaminant concentration, the process comprising the steps of:(a) providing a plurality of hold-up tanks; (b) feeding the loaded solvent s-ream in dependence on its contaminant concentration to one or more of the hold-up tanks and; (c) allowing lowed solvent to flow from the plurality of hold-uptanks to obtain a smoothed loaded solvent stream having a reduced time-varyingcontaminant concentration. The inventio further provides a treating unitcomprising a circuit for circulating a solvent stream, which circuit includesa device for smoothing contaminant peak concentrations, said device comprisinga plurality of hold-up tanks each hold-up tank having at least one inlet andan outlet equipped with an outlet valve, the device further comprising aninlet distributor allowing the control of solvent flow to one or more of thehold-up tanks.
