US stocks of propylene for non-fuel use fell last week for the first time in 13 weeks, Energy Information Administration data showed Wednesday.
Propylene inventories saw a draw of 59,000 barrels to 3.098 million barrels in the week ended May 19, the data showed.
Sources attributed the draw to an ongoing turnaround at a major propylene producer's plant.
Nationwide, refinery run rates last week rose 0.1 percentage point to 93.5%, also higher than the 89.7% rate seen last year at this time, the EIA data showed.
In the spot market, US polymer-grade propylene was assessed 1 cent higher Wednesday at 38 cents/lb FD USG for May deliveries and at 37.75 cents/lb FD USG for June deliveries. US spot refinery-grade propylene rose 1.25 cents, assessed at 25.75 cents/lb FD USG.
