CTO fire seen having no long-term US TOFA impact

US pine chemicals producer Mainstream Pine Products expects a recent fire at its crude tall oil (CTO) fractionation site in North Charleston, South Carolina, to have a limited impact on US supply of tall oil fatty acid (TOFA).

"We do not expect major effects on the US TOFA markets, and no long-term effects. This incident occurred during a planned outage, so inventories had been built in advance," the company told Argus. Repairs will "take weeks, not months", it added.

The 12 May fire was contained to part of the refinery. There was no damage beyond the affected column, the company said. Local reports indicate the North Charleston Fire Department is investigating the cause.

There has been no immediate disruption to TOFA supply, one buyer said. And domestic availability is sufficient to meet demand, according to market participants.

Mainstream supplies TOFA to the domestic market alongside US-based specialty polymers and pine chemicals producer Kraton. Mainstream supplies certain higher-rosin grades, while its TOFA volumes are smaller than Kraton's, participants said.

The North Charleston plant, formerly owned by Ingevity, has CTO refining capacity of 110,000-120,000 t/yr, according to market estimates. Mainstream completed the acquisition on 1 January this year.

TOFA is one of the fractions obtained from CTO distillation.
