Abstract

Abstract: The crude sulfur and waste desulfurization liquid from HPF unit,after pre-treatment,are respectively sent to combustion furnace.The high temperature flue gas is decreased to 300~320 ℃ via waste heat boiler and produced to 98% concentrated sulfuric acid after twice conversion and twice adsorption.This process produces zero waste liquid,which can thoroughly solve the problem of waste desulfurization liquid pollution and meet the requirement of environment-friendly production.

Key words:

"> Crude sulfur, Concentration, Combustion, Acid-making
