HOUSTON (ICIS)--INVISTA officials did not return a query on Thursday about a report of chemical air emissions at  at its Sabine River adipic acid (ADA) process unit in Texas.

ADA is used to produce nylon 6,6.

According to a filing with the Texas Commission on Environmental Quality (TCEQ), four chemicals were emitted to the atmosphere on Wednesday with estimated amounts given - 12,000 lbs (4.4 tonnes) of nitrous oxide, 40 lbs of carbon monoxide, 30 lbs of nitrogen dioxide and 15 lbs of nitrogen oxide.

The Sabine River facility has an ADA capacity of 220,000 tonnes/year, according to ICIS plants and projects.

A third-party utility maintenance team triggered a momentary power shutdown that caused the nitrous oxide compressor and other equipment to shut down, INVISTA said in the regulatory filing.

It also said that when the compressor shut down, the unit automatically interlocked and vented through the absorber vent.

The compressor and unit were returned to service.
