he removal of acidic components (primarily H2S and CO2) from hydrocarbon streams can be broadly categorized as those depending on chemical reaction, or adsorption. Processes employing each of these techniques are described. The principle process stream is the removal of the acid gases by counter flowing contact with an amine solution, commonly known as Amine Gas Sweetening. The acidic components removed are termed acid gas streams (containing H2S,) and may be flared, incinerated, or converted to elemental Sulphur in a Sulphur Recovery Unit. Various Sulphur Recovery processes (primarily The Modified Claus Process) are discussed.

A significant fraction of the natural gas produced today contains acid gases--primarily hydrogen sulfide (H2S) and carbon dioxide (CO2) in sufficiently high concentrations as to be considered subquality. These contaminants must be removed for the gas to be safely and economically utilised. The Amine Gas Sweetening & Sulphur Recovery course is designed for delegates as a single source of information on:

• The identity and characteristics of the waste streams produced by the major gas sweetening and sulfur recovery processes

• The possible effects of process chemistry and the nature of the gas being treated on waste characteristics

• Currently available options for waste stream disposition

• The effects of environmental regulations, both current and foreseeable, on waste stream disposition
