Sembcorp Industries, the energy, water and marine group operating in 17 countries, says it signed a 20-year long-term utilities services agreement with Jurong Aromatics Corporation (JAC) for the supply of steam and other water and wastewater treatment services to JAC’s upcoming aromatics complex located in the west of Singapore’s Jurong Island petrochemical cluster.

To provide these services to JAC, Sembcorp will build a multi-utilities facility adjacent to the JAC aromatics complex and a new gas-fired combined-cycle gas turbine cogeneration plant close to the JAC aromatics complex, to provide integrated supply of steam, water and wastewater treatment services.

With a total investment cost of $800 million, the new multi-utilities facility and cogeneration plant are expected to be completed by the third quarter of 2013, and will be funded through a mix of bank borrowings and internal sources. Occupying a land area of around 5.3 hectares, the new multi-utilities facility will be similar to Sembcorp’s existing multi-utilities centre in Jurong Island’s Sakra district and will supply around 350 tonnes of steam per hour, as well as other water and wastewater treatment services.

The new combined-cycle gas turbine cogeneration plant will have a capacity of 400 megawatts of power and 200 tonnes per hour of process steam in its initial phase. The development of the cogeneration plant is subject to the approval of relevant authorities.

Sembcorp says its expansion into the upcoming growth area in the west of Jurong Island will complement its current operations in the Sakra and Seraya districts of the island. Earlier in June, Sembcorp had announced that it had secured a long-term wastewater treatment contract from Lanxess for its upcoming butyl rubber production facility in Tembusu.
