As a result, refineries have become a more important source of propylene. However, refineries treat propylene as a by-product.
Recently, though, several
Unlike other sources of propylene, these plants would rely on propane to produce the monomer. Moreover, the plants would be dedicated producers of propylene.
This should help ensure that the propylene will be available when Braskem and other consumers need it, Musa said.
The PDH plants also could lead to a different pricing dynamic for propylene, Musa said. Since propane is derived from natural gas, on-purpose propylene could become more dependent on gas prices versus oil prices.
The PDH plants could even bring more stability to prices, he said.
However, Musa warned that it is unclear what the ultimate effect the PDH plants would have on propylene pricing.
That effect will depend on when the plants start operations, how they are operated and how the propylene is marketed, he said.
Some producers could use most of the propylene internally, Musa said. Other companies may back away from building new plants.
So far, PetroLogistics as well as Enterprise Products, Dow Chemical and Formosa Plastics have announced plans to increase on-purpose propylene capacity. Williams is considering building a PDH plant in
Already, Braskem has signed an agreement with Enterprise Products to secure some of the propylene to be produced at the company's new plant.
