Absorbing System - Sulphuric Acid

Introduction. The Absorbing Acid System absorbs the sulphur trioxide (SO3) that is formed in the converter to produce sulphuric acid.The reason for absorbing the SO3 is to achieve the desired production of sulphuric acid and to avoid environmental problems that would result if the SO3 were allowed to exscape to the environment. Efficiently absorbing the SO3 will also help to maintain a clear ...

Sulphuric acid - HUGO PETERSEN

Sulphuric acid. At the beginning of the 20th century HUGO PETERSEN set new standards for the production of sulphuric acid with the PETERSEN tower plant process, whereby the obsolete lead chamber process was replaced by a new tower plant process. For more than 110 years HUGO PETERSEN has built sulphuric acid plants to meet the highest standards.

The contact process is a modern method used by industries for manufacturing concentrated sulfuric acid. During this process, sulfur dioxide and oxygen are passed over a hot catalyst (V 2 O 5). They unite to form sulfur trioxide, which combines with water to produce sulfuric acid. Contact Process Equation. 2SO 2(g) + O 2(g) ⇌ 2SO 3(g)
