Case Study

Running a plant at minimum cost and within emission requirements - Habshan 5

Working on one of the largest sulphur removal plants to deliver the best operational and economic outcomes for the client's project.

The Situation

Habshan 5 consists of two rich gas trains and two lean gas trains. The plant is designed to process 1,000 million standard cubic feet per day (mmscfd) of offshore gas from Umm Shaif and an additional 1,000 mmscfd of onshore gas comprising a mix of associated gas from ADCO and non-associated high sour gas from the Habshan fields. 

Approach

The Advisian Sulphur Solutions team (formally WorleyParsons Consulting) worked closely with GASCO to develop the optimum process scheme before producing the basic engineering design package for the sulphur removal and tail gas treating units (TGU) at Habshan. In this case, the project selected Flexsorb solvent which minimised both equipment size and energy usage. The Habshan 5 facility comprises four trains producing a total of 5,200 tonnes of sulphur per day, making this the largest sulphur removal plant designed by WorleyParsons. 

Results
