介绍了硫酸厂甘汞法除汞技术的基本原理、工艺流程及技术演化与变革。传统甘汞法虽然具有较高的除汞效率（可达99.8%）,但某些厂仍存在甘汞洗涤器出口汞含量超标问题。Kimre公司采用在甘汞洗涤器出口增设一台2级SXFTM半错流洗涤器的改进工艺,取得良好效果,产品酸w（Hg）可由0.000 05%～0.000 07%降至0.000 02%～0.000 03%。通过进一步的技术改进和优化,Kimre公司最新开发一项用以冶炼烟气除汞的改进工艺———MercurEx B-GONTM技术,并由Hugo Petersen公司独家推广这一技术。在电厂烟气应用中,该技术可以除去烟气中的汞、二恶英及其他重金属。

Basic principle,process,evolution and revolution of mercury removal using calomel process in sulphuric acid plant are described.Some plants had very urgent issues with excessive mercury exiting their traditional calomel process scrubber.Kimre Inc adopted an improved technology and achieved good results by installing a two-stages SXFTM Semi-Cross Flow Contactor at the outlet of calomel scrubber.The mercury content in product acid was decreased substantially from 0.000 05 wt%-0.000 07 wt% to 0.000 02 wt%-0.000 03 wt%.By Further technical improvement and optimization,an improved process trademarked as MercurEx B-GONTM for the removal of mercury from gases generated in smelting has been developed by Kimre Inc and Hugo Petersen GmbH exclusively markets this technology.It can remove mercury as well as dioxins,and other heavy metals in power plant off-gases applications.
