Sulphur Recovery Unit are exposed to severe and extreme operating conditions, highest level of plant reliability and availability are mandatory, since unplanned SRU shut-down can cause important loss of production that cannot be tolerated in the current critical Oil & Gas Market conditions. At the same time, due to the dangerous nature of H2S, safety has to be put first in design as well as in plant operation in order to achieve the mandatory target of Zero Accident. When safety, environmental issues and production rates are involved, it becomes of paramount importance to fully understand how the Process Unit is performing and which is the most effective strategy to be adopted, in real time, to achieve both operation excellence and long term performance of the unit. A continuous monitoring and gathering of plant and laboratory data is normally conducted to support operational activity, nevertheless it may be not easy to understand what is really happening "behind the steel". DCS reading sometimes are not consistent, are misleading or are not available, while basic information like feedstock, fuel gas and flue gas composition are not always available on continuous basis. In this contest, KT Kinetics Technology has developed the SA-SRU™, Supervisory Analytic for Sulphur Recovery Unit, which is a digital platform aiming to help Operators to reach SRU Operational Excellence. SA-SRU™ is an engineering tools based on KT leading know how in design and operation of SRU and VMG expertise on thermodynamics and process simulation. The digital platform has been specifically built to be easy to work with, capable to model the real and correct operation of the Unit starting from few basic data and process constrains. The main purpose of this paper is to present real cases in which the new digital platform has been applied in a SRU not only to improve the performance, reliability and availability of the plant but also to achieve a real saving of the operating costs.
