DuPont technology selected for refinery

The PETRONAS owned PRPC refinery and cracker will install three DuPont MECS DynaWave Scrubbers at the facilities in Malaysia.

DuPontTM MECS® DynaWave® technology, licensed by MECS, Inc., a wholly owned subsidiary of DuPont, has been selected by a major international oil and gas services provider for the installation of three custom-engineered scrubbing systems for sulfur dioxide removal at PRPC Refinery & Cracker Sdn. Bhd, a subsidiary of PETRONAS, the Malaysian National Oil Company. The DynaWave units are set to be delivered to the company’s refinery and petrochemicals integrated development (RAPID) project refinery in Pengerang, Southern Johor, Malaysia, before the end of the year for subsequent fitting.

“Each of the specially engineered DynaWave scrubbers will treat the off-gas of one sulfur recovery unit (SRU) and its dedicated tail gas treatment unit (TGTU),” said Angus Yip, MECS Sales Manager for South East Asia & Australia - New Zealand. “PRPC requires SO2 emission levels to be lower than 150 mg/dNm3, which DynaWave technology can guarantee under any given set of upstream conditions. Malaysia is now the second country in Asia Pacific and the first in South East Asia to benefit from the added reliability that this technology can offer for SRU emissions control and air quality improvements.”

All three scrubbers consist of two reverse jet stages located in an inlet barrel, which is connected to a disengagement vessel. They are capable of handling high inlet acid levels, which make it possible to bypass upstream TGTUs while still meeting and even exceeding regulatory emissions requirements. DynaWave scrubbers can be designed to cope with inlet temperatures of up to 1200°C, but for PRPC the choice fell on optimising heat recuperation from the incinerator so that these DynaWave scrubbing units will take incoming gas at around 300 - 350°C.

The RAPID project represents a significant investment of US$16 billion for PRPC. Scheduled for completion in 2019, it is expected to be capable of processing 300 000 bpd and will operate three 470 tpd sulfur recovery units.
