Total Petrochemicals USA started a 3 week revamp of a toluene disproportionation (TDP) unit at its 232,000 bpd in Port Arthur, Texas. Benzene and paraxylene are made from toluene at a TDP unit.
The unit is estimated to be shut until Dec. 9 for an overhaul that will include working on the concrete refractory lining the inside of the catalyst chamber.
