There are several synonyms for desulphurization, including desulfurization, desulphurisation, sulphur removal, and sulfur extraction. Other related terms include sulphur abatement, reducing sulphur emissions, and capturing sulphur dioxide. These terms are commonly used in industries such as power generation, oil and gas, and chemical manufacturing.

The development and use of desulphurization technologies is an important aspect of sustainable industrial practices.
