Waste Heat Boiler - an overview | ScienceDirect Topics

Sulfuric acid method. In this method the gas is cooled in waste heat boilers and its dust content is removed in cyclones and electrostatic precipitators. The gas at 350 °C is cooled in heat exchangers to about 200 °C using concentrated H 2 SO 4 as a heat exchange medium. It is then scrubbed with the same acid, which is now at 150–200 °C, to convert elemental mercury into a sulfate according to

Firetube Boilers, Waste Heat Boilers | Optimus Industries

Steam systems are most commonly associated with sulphur burning sulphuric acid plants, however, acid regeneration plants have steam systems and some metallurgical acid plants. When the process generates waste heat, the generation of steam is the simplest way to put the energy to use either for process uses or for the generation of electrical power.

Plant Construction & Waste Heat Systems for the Chemical

Acid regeneration plants include plants that decompose spent sulphuric acid into SO2and H2O to be regenerated in to fresh acid and plants that take waste sulphur gases (H2S, CS2) to produce acid. Some plants are a combination of two types of plants. Sulphur is sometimes burned in acid regeneration and metallurgical plants to increase SO2

Waste Heat Boilers - Sulphuric Acid

Boilers in acid plants are waste heat boilers cooling gases from sulphur furnaces, regeneration furnaces and between catalyst beds. Types of Boilers. There are basically two types of boilers in common use: 1) Firetube 2) Watertube. Firetube Boilers. In firetube boilers the hot gases are confined within tuibes arranged in a bundle within a shell.

Sulfuric Acid - Veolia North America

Veolia owns and operates seven sulfuric acid plants throughout the United States. Some of these plants are sulfur-burning plants that use a contact process (refer to "Sulfuric Acid Process, page 3). Other plants use Spent Acid Regeneration (SAR) processes, where unreacted sulfuric acid that was used in other processes is regenerated for re-use.
