HOUSTON (ICIS)--Dow Chemical’s board of directors has authorised capital to finalise detailed engineering and to purchase equipment for the company’s planned world-scale propylene facility in ?xml:namespace>
Dow said basic engineering work for the on-purpose propylene production facility has begun.
The project is on track for production start-up in 2015, it added.
On-purpose propylene production uses propane as a feedstock versus obtaining it as a refinery-sourced byproduct.
Dow added that the board’s authorisation marks a milestone in its plan to benefit from low-cost shale gas-based feedstocks in the
“Our company was among the first in our industry to declare a comprehensive plan to take advantage of the increasing supplies of US natural gas liquids, and we remain on track to implement that plan, which will create thousands of domestic jobs,”
Dow announced its plan for the project in April 2011.
The two main sources of propylene are as a byproduct from the steam cracking of liquid feedstocks such as naphtha as well as LPGs, and from off-gases produced in fluid catalytic cracking (FCC) units in refineries.
The remainder of propylene is produced using on-purpose technologies such as propane dehydrogenation (PDH) and metathesis.
The dominant outlet for propylene is polypropylene (PP).
