Technological design of the processes of transforming and heat transferring in sulfuric acid producing using sulfur

Abstract

Sulfuric acid is an important raw material in chemical industry,it is widely used in many industries.Sulfuric acid has high qualities in acidity,causticity and water absorption.The sulfuric acid used in industry is usually an aqueous solution with a high concentration,sulfur,pyrite and smelt smoke are used as raw material in industry,currently domestic producing of sulfuric acid uses pyrite as the raw material mainly,the proportion of sulfur is gradually increasing in recent years,compared to pyrite,using sulfur as the material of producing sulfuric acid has advantages of simpler craft processes,lower investment,higher rate of energy utilizing,better environment benefits and etc.

This paper talks from the basic properties of sulfuric acid,and analyzes the current status of sulfuric market,systematically introduces the backgrounds and craft conditions of acid producing using sulfur,then explains the principles,craft processes and information about equipment.This paper reverts the whole process of acid producing using sulfur in form of steady simulations,and focuses on the analyzing and calculating of the processes of transformations and heat transferring,to achieve the understanding,analyzing and further improving of the crafts.

Key word:acid producing using sulfuric,steady simulation,double transformations and absorption.

Key Words: acid producing using sulfuric；steady simulation；double transformations and absorption.
