A method for removing a saeuregaskomponente from a gas stream

摘要

A process for removing an acid gas component from a gas stream is shown. The gas is passed in contact with finely divided nepheline syenite which selectively sorbs acid components such as hydrogen fluoride, sulfur dioxide and silicon tetrafluoride from the gas. The nepheline syenite is desirably treated with water to increase its sorbant characteristics.
