Efficiently Reducing SO2 Emissions on a Smaller Plot: A Case Study at Ta-Lin Refinery, Taiwan

A typical approach has been to use a highly efficient amine-based tail gas treatment unit (TGTU) downstream of the Claus plant.

Today, an alternative configuration has been proven to add reliability to the overall Claus plant, especially in terms of emissions during emergency shutdowns and startups. Installing a highly flexible reverse jet scrubber between incinerator and stack makes it possible to operate a more cost-effective TGTU (such as a direct oxidation or sub-dewpoint process). This solution efficiently reduces sulfurous emissions on a smaller than usual plot space at a lower investment cost. When combined with the unique flexibility of the MECS® DynaWave® technology, this approach ensures emission control at all times, even during bypass of the TGTU or entire Claus plant.

This presentation will discuss the reasons for and results from an installation of such a sulfur removal system by the state-owned CPC Corporation, Taiwan at its Ta-Lin refinery.
