MECS® DynaWave® technology, licensed by MECS, Inc., a wholly owned subsidiary of DuPont, has been selected by international oil and gas services provider Petrofac for the installation of three custom engineered scrubbing systems for sulfur dioxide removal at PETRONAS, the Malaysian National Oil Company. The DynaWave® units are set to be delivered to the company’s RAPID Project refinery in Pengerang, Southern Johor, Malaysia in the 2Q16 for subsequent fitting.
“Each of the specially engineered DynaWave® scrubbers will treat the offgas of one Sulfur Recovery Unit (SRU) and its dedicated Tail Gas Treatment Unit (TGTU),” says Angus Yip, MECS Sales Manager for South East Asia & Australia - New Zealand. “PETRONAS requires SO2 emission levels to be lower than 150mg/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 DynaWave® technology can offer for SRU emissions control and air quality improvements.”
All three DynaWave® 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 makes 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 PETRONAS 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 (Refinery and Petrochemicals Integrated Development) project represents a significant investment of US$16 billion for PETRONAS. On completion in 2019 it is expected to be capable of processing 300 000 bpd and will operate three 470 tpd sulfur recovery units.
