AGENT AND METHOD FOR REMOVING HYDROGEN CHLORIDE IN EXHAUST GAS, AND METHOD FOR MAKING SLAG

摘要

PURPOSE:To easily solve environmental problems associated with waste incineration and to provide an effective material by removing efficiently hydrogen chloride generated from the incineration and making slag easily from recovered fly ash. CONSTITUTION:An agent for removing hydrogen chloride in exhaust gas is composed of a mixture of lime powder and porous calcium silicate hydrate granules of light weight foam concrete granules. In a hydrogen chloride removing method, the mixture is contacted with hydrogen chloride in exhaust gas. Slag is made from a mixture of the hydrogen chloride removing agent which removed hydrogen chloride and recovered fly ash.
