改造净化工艺设备　适应高砷硫铁矿制酸

Modified Equipmet of Purification Process for sulfuric Acid Production with High-Arsenic Suiphurous lron Ore

本文介绍了以高砷硫铁矿作制硫酸原料给生产工艺带来的问题，通过对净化工艺中的气液分离器和除沫设备的改造，问题得到了较好的解决。净化后气体中的砷含量大大降低，延长了触媒寿命和有关设备的使用年限。

The paper describes the problems resulted irom suliuric acid produtieo with high-arsenic as material.The problem has been successfully solpved through modification of gac trap and drfoaming equipment.Arsenic coutent decreases greatiy after gas is purified.This causes the service life of catalyst and devices to be prolonged.
