As a consulting Process/Chemical Engineer in Calgary, Canada, Mr. Ahmed S Said started his career in the oil & gas engineering and construction business by designing, procuring and overseeing the construction of oil & gas well-site facilities, pipeline tie-ins and sweetening and dehydration installations for processing natural gas. Now a senior executive with natural resource financiers Forbes & Manhattan Inc., Mr. Ahmed Said utilizes his technical background while financing the development of large scale natural gas projects utilizing the importance of safe removal of sulfur, and its by products, from natural gas when it is processed.

Unprocessed gas, containing sulfur products, straight from the well is called “sour gas” because of the odor of hydrogen sulfide, the gaseous form of sulfur. Conversely, “sweet gas” results from removing the sulfur, which is both toxic to breathe and corrosive.

Sweetening employs chemicals known as amines to remove hydrogen sulfide. Sweetening plants pump the sour gas through towers containing amines in liquid form. In the United States, 95 percent of sweetening operations use this method.

Reusability is built into the system. Refineries can recover the leftover sulfur into its elemental form, a yellow powder, using a method known as the Claus process, which can extract 97 percent of sulfur from the waste products of sweetening. Amines can also be used repeatedly to sweeten gas.
