Saudi Aramco, Total and McDermott sign ethylene patent technology contract

Recently, Saudi Aramco, Total and McDermott signed an ethylene patent technology engineering service contract for the Jubail petrochemical proje.

McDermott said the contract uses McDermott's Lummus technology, and McDermott will provide the project with a patent license, a basic engineering design package, extended basic engineering, training, technical services and proprietary equipme.

Specifically, technical services include olefin technology, low pressure recovery (refinery tail gas recovery and treatment), coal gas hydrotreating, catalytic distillation to produce CDMtbe methyl tertiary butyl ether technology, CDIB (methyl tertiary butyl ether reverse cracking to produce high Purity of isobutene and methanol) and BASF NMP (N-methylpyrrolidone butadiene extraction process) and so .

Additionally, Lummus will supply its proprietary Short Residence Time (SRT) heater for the proje.

There will also be $500-250 million in contract orders in the third quarter, McDermott sa.

Aramco said the latest contract follows a memorandum of understanding between the joint venture and South Korean petrochemical company Daelim Dael.

Front-end engineering and design of the polyisobutylene plant began in February this year and will be completed in the fourth quarter of this ye.

Aramco and Total said the new unit includes a mixed feed steam cracker (50% ethane and refinery gas) with a capacity of 5 million tonnes/year of ethylene and related petrochemicals, bringing the overall output to more than 7 million tonnes/year Years of high-quality chemical produc.

The proposed Amiral petrochemical complex is expected to be commissioned in 2024 and is currently in the FEED pha.

In addition to the total investment of about 5 billion US dollars for the ethylene project of Saudi Aramco and Total, other supporting chemical plants need to invest 4 billion US dollars, which means that the total investment of the project is about 9 billion US dolla.
