LACC LLC, a venture of Lotte Chemical Corp. subsidiary Lotte Chemical USA Corp. and Westlake Chemical Corp., has let a contract to McDermott International Ltd. to deliver engineering, procurement, and construction for a seventh heater to be added at LACC’s 1 mta ethane cracking complex in Westlake, La. Designed to support cracker operations at the site, the new heater will be equipped with proprietary Short Residence Time (SRT)-III technology from McDermott’s preferred technology partner Lummus Technology LLC. While new cracking furnaces typically are added to cracker operations to accommodate increased capacity, neither Lotte Chemical nor Westlake Chemical have indicated any official plans to expand production at the Westlake complex. Commissioned in 2019, the USD 3.1-billion, 250-acre southwestern Louisiana petrochemical complex which produces 1 mta of ethylene, also houses a 700 kta MEG plant operated by Lotte subsidiary Lotte Chemical Louisiana LLC.
