Petronas lets contract for RAPID complex

State-run Petronas, through a contractor, has let a contract to MECS Inc., a subsidiary of E.I. DuPont de Nemours & Co., to provide sulfur-removal technology for its refinery and petrochemical integrated development (RAPID) complex at Pengerang in southeastern Johor, Malaysia (OGJ Online, May 13, 2011).

MECS will install three custom-engineered scrubbing systems equipped with its proprietary DynaWave sulfur dioxide removal technology to treat off gas for one of RAPID’s sulfur recovery units (SRU) and a dedicated tail gas treatment unit (TGTU), MEC said.

The DynaWave scrubbers are intended to help Petronas reduce sulfur dioxide emission levels at RAPID to below 150 mg cu m/day, the service provider said.

All three scrubbers, which consist of two reverse-jet stages located in an inlet barrel connected to a disengagement vessel, will be equipped to handle high inlet acid levels, making it possible to bypass upstream TGTUs while still meeting and even exceeding regulatory emissions requirements, the service provider said.

The scrubbing units for RAPID will take incoming gas at temperatures of 300-350° C. in order to optimize heat recuperation from the incinerator.

MECS plans to deliver the DynaWave units to the RAPID project during this year’s second quarter for subsequent fitting.

On schedule to be completed in 2019, RAPID will include three 470-tonne/day SRUs, MECS said.

With a planned capacity of 300,000 b/d, the RAPID refinery will produce naphtha and liquid petroleum gas feedstock for the petrochemical complex, as well as gasoline and diesel meeting European specifications to help address Asia-Pacific’s growing need for petroleum and petrochemical products (OGJ Online, Oct. 21, 2015; Mar. 27, 2014).

The $27-28 billion refinery and petrochemical complex will have a combined capacity to produce 7.7 million tonnes/year of various grades of products, including differentiated and specialty chemicals products (OGJ Online, Oct. 23, 2014).
