Rentech Nitrogen Partners, L.P. announced the achievement of key milestones for the ammonium sulfate (AS) debottlenecking project at its Pasadena Facility. With the achievement of these milestones, the commissioning phase of the project is now complete.

The plant now produces ammonium sulfate at an average instantaneous rate of 2,100 tons per day, the targeted rate for the project. The increased rate represents a 20% increase from the plant’s previous nameplate production capacity. In addition, on-stream rates and plant reliability have improved, and the quality of ammonium sulfate is the highest since the facility began AS production in 2011.

John Diesch, president of Rentech Nitrogen, commented, “We are extremely pleased with the improved operating performance of the Pasadena Facility since the completion of the debottlenecking project. Importantly, we expect work completed during the debottlenecking project to drive lasting improvements in the plant’s operating performance, reliability, and product quality.” Diesch added, “We are seeing repeat customers after our first full year of production, and as a result of better liquidity in the domestic market, we are contracting sales at a faster pace compared to last year.”
