Title: Removing mercury vapor from waste gases using an absorber/desorber column and a washing solution
Inventor: SPRENGER SUSANNE DIPL CHEM
IPC: B01D53/78
Filed: 1997-12-05
Abstract: The Hg vapor is removed by a washing solution circulating in an absorber/desorber reactor column. The solution contains an oxidizing agent such as I2 that converts the Hg to a soluble material. In the upper part of the column the I2 is absorbed from the gas phase into the solution and in the lower part it passes from the solution into the gas phase. The washing solution is recharged with I2 to make up for quantities lost or reacted. The operating conditions are such that the equilibrium line and the working line of the column are parallel. The desorber part of the column is 5-20  deg  C warmer than the absorber part of the column is 5-20  deg  C warmer than the absorber part. The oxidizing agent is iodine which converts the Hg to mercury iodide. After separating the Hg from the washing solution, it is recycled back to use in the column again.
