Sasol of South Africa said it was trying to resolve the unidentified technical problems, which were causing a build-up of fine or powder-like material in the gas-to-liquids process.
"We are confident we will resolve it (the problem) based on our long experience with this technology," said chief executive Pat Davies. "It will not affect our overall GTL growth plans."
Production at the $1 billion plant, built in Qatar by a joint venture of Sasol (49%) and Qatar Petroleum (51%), is running at 7000 bpd to 10,000 bpd.
