Abstract
Oil and gas industries employ sulfur recovery processes for limiting SOx emissions. Such emissions
have many dangerous impacts on the troposphere environment. In addition, world demand for sulfuric
acid products is increasing due to continuous increases in world population and to support economical
growth all over the world. From financial and environmental perspectives, investing in efficient sulfur
recovery processes is a very promising project.
The objective of this work is designing a Modified Claus plant accompanied with a Tail Gas Treatment
(TGT) process capable of producing 800 tonnes/day of sulfur from sour gas streams. Moreover, the
process has to be efficient in recovering at least 99% of sulfur from sour gas. This report shows a Front
End Engineering Design for the proposed sulfur recovery process. The major objective in this work is to
provide an estimate for the cost of the project and assessing this estimate from an economical point of
±30%.
