Exxon uses crude oil instead of refined naphtha oil to make petrochemicals
From Article by Florence Tan and Seng Li Peng, Reuters, January 8, 2014
SINGAPORE – - ExxonMobil officially launched the world’s first chemical unit that processes crude oil in Singapore, aiming to lower costs to better compete with rivals in a market saddled with excess capacity.
Chemical companies typically process refined oil products such as naphtha – created by separating crude oil into lighter groups – at facilites called crackers to create petrochemicals like ethylene and propylene. These are further processed into products such as plastics, soaps or synthetic fibres.
But Exxon’s new cracker in Singapore allows the company to bypass the refining process by processing crude directly into petrochemicals. ”This is the right place to do crude cracking because it gives us an advantage over the predominant feedstock in the region,” ExxonMobil Chemical’s president Stephen Pryor told Reuters. ”The cracker we’ve built is by far the most feed flexible cracker we’ve ever built. It can crack anything from light gases to heavy liquids, including crude oil.”
The new technology helps reduce raw material costs, energy consumption and carbon emissions, Pryor said, while the cracker also produces fuel components.
The cost of Brent crude is more than $160 a tonne lower than Asia’s naphtha NAF-1H-TYO, Reuters data showed. Crackers in Asia typically use naphtha as a feedstock, while those in the Middle East enjoy a cost advantage as they process cheaper ethane and propane gases into petrochemicals.
The multi-billion dollar complex on Singapore’s Jurong Island includes the 1 million tonne per year (tpy) steam cracker as well as production of at least 1.4 million tpy of polymers and elastomers.
CHEMICAL DEMAND RISING
An improved economic outlook in the United States and better demand in China is expected to raise global chemical demand growth in coming years. Global petrochemicals growth of 4.1 percent in 2014 and 4.5 percent in 2015 is predicted, up from 2.1 percent last year.
“After a couple of very slow years, we saw good demand growth in China last year,” said Pryor. “With China’s export sector picking up, we would expect that to continue.” Global chemical demand for primary petrochemicals was expected to grow by about 50 percent over the next decade, with China accounting for half of the growth, he added.
To meet this demand, Exxon also plans to raise ethylene capacity at its joint venture with Saudi Aramco and Sinopec in southern China Fujian by 200,000 tonnes per year in 2015. At the Singapore plant, Exxon could also produce specialty petrochemicals such as butyl rubber for tires and premium resins for adhesives, Pryor said.
Yet, supply from the United States could jump as petrochemical producers, including Exxon, launch projects to take advantage of cheap ethane gas from the shale resources boom. Exxon plans to build a 1.5 million tpy ethylene complex at Baytown, Texas by 2016.
“Demand will grow but it will be a competitive marketplace from a standpoint of capacity and that means that marginal liquid crackers are going to be under a lot of pressure,” Pryor said. ”You already see that in Europe, you see that in Japan and you’re going to see it throughout the region.”
French oil major Total and Ineos have said they will shut loss-making petrochemical plants in France and Scotland as Europe readies for a competitive assault from U.S. rivals armed with cheap feedstock.

ExxonMobil used 40 proprietary technologies in the newly expanded Singapore Chemical Plant, the company’s largest petrochemical complex in the world.
The expansion includes the new 1m tonne/year steam cracker that can use crude as feedstock; two 650,000 tonne/year polyethylene units: a 500,000 tonne/year polypropylene unit; a 300,000 tonne/year specialty elastomers unit; a benzene extraction unit that can yield 340,000 tonnes/year of benzene.
It further includes a 125,000 tonne/year oxo-alcohol unit expansion, an 80,000 tonne/year paraxylene expansion, as well as a 220-megawatt power cogeneration unit.

NOVA Chemicals announces first petrochemicals utilization of Marcellus Shale ethane at its Ontario cracker
Calgary, Alberta (January 16, 2014) – NOVA Chemicals Corporation (NOVA Chemicals) today celebrated its commitment to the Sarnia, Ontario region during a ceremony to commemorate the first barrels of ethane sourced from the Marcellus Shale Basin being utilized at its Corunna, Ontario cracker.
NOVA Chemicals began consuming this new feedstock in late December 2013 as part of a project to revamp its Corunna, Ontario cracker to utilize up to 100% natural gas liquid feedstock in line with its strategy to ensure the long-term economic viability of its Ontario assets.
“The introduction of Marcellus Shale ethane into the feedstock diet at our Corunna cracker marks a tremendous milestone in our journey to utilize more cost-competitive feedstock in Ontario, which should result in stronger and more consistent financial performance for our Ontario-based assets,” stated NOVA Chemicals CEO Randy Woelfel. “This is a critical component to our NOVA 2020 growth strategy of capitalizing on new feedstock sources to meet our current needs and expanding customer demands.”

I read this article completely on the topic of the difference of most recent and previous cracking technologies, it’s amazing article.
Generally, we do not realize there is such innovation in the complex world of the technology based on chemistry and physics.
But, who is watching for environmental impacts, who is speaking up for the Earth?
Thank you.
