Benefits of technology

This patented technology describes an improved method for removing sulfur from calcium carbonates by adding certain substances that help them absorb or react with acidic gases like H2/S x , CO.3 /COO1.5 2. By doing this it helps prevent damage caused during processing steps such as milling processes.

Problems solved by technology

The technical problem addressed by this patented technology is finding ways to reduce sulfur dioxide emissions from combustion sources without requiring expensive or complicated chemical treatments while maintaining efficient removal of harmful substances such as nitrogen oxides (NO) at reasonable cost levels.

Abstract

The invention relates to the field of chemical industry, and particularly relates to a desulfurization additive as well as applications and a using method of the same. The desulfurization additive contains the following raw materials in parts by weight: 30-40 parts of accelerant, 50-60 parts of activator and 5-15 parts of catalyst. The desulfurization additive can be used in a wet-process flue gas desulfurization technology of limestone or limestone gypsum. The using method of the desulfurization additive comprises the steps of: adding the desulfurization additive in a circulation loop of a limestone wet-process desulfurization circulation system; stirring; and adding the desulfurization additive by a set frequency. The desulfurization additive is capable of enhancing the reaction rate of desulfurization.
