Under the contract, due to be signed in the first week of April, Enppi will install a new de-ethaniser column system and associated ancillary systems to process an additional 195,000 barrels a day (b/d) of ethane plus natural gas liquids (NGL) streams, which are a mixture of ethane, propane, butane and pentane. The project will raise total fractionation capacity at the plant to 585,000 b/d.

It will also entail the installation of associated vessels, heat exchangers and cooling equipment. In addition, a new 600-pound steam boiler will be installed and utility systems will be modified to accommodate the new process equipment. The US’ Jacobs Engineering has carried out the front-end engineering and design (FEED) package. The project is due to come on stream in December 2008.

Enppi won the contract against competition from two other companies – US-based ABB Lummus Global and Germany’s Uhde.
