SULPHURIC ACID CONVERSION PROCESS

摘要

A process for the production of sulphuric acid comprises providing a sulphuric acid precursor stream comprising oxygen and sulphur dioxide; feeding the sulphuric acid precursor stream to a sulphuric acid converter to produce a sulphuric acid stream and a gaseous stream containing unreacted sulphur dioxide; and, subjecting the gaseous stream to a regenerable sulphur dioxide recovery process to obtain a sulphur dioxide rich stream and a sulphur dioxide lean stream.
