NOx system permitted for power unit at Louisiana chemical plant

The Louisiana Department of Environmental Quality went out for comment on Sept. 25 on draft air permit approvals that would allow Eagle US 2 LLC and Lotte Chemical USA Corp. to add new chemical production facilities, and to install compensating NOx controls on an existing power generation unit.

The subject facility is located at Westlake in Calcasieu Parish. A hearing will be held on Oct. 29 at the Calcasieu Parish Council Chambers. Comments will be taken until Nov. 2. 

Eagle US 2 LLC, a wholly-owned subsidiary of Axiall Corp., and Lotte Chemical USA, a wholly-owned subsidiary of Lotte Corp. of South Korea, requested permits to construct two new chemical manufacturing process units in Calcasieu Parish adjacent to Eagle’s existing chemical manufacturing complex, called the Lake Charles Complex. The new chemical manufacturing process units will be an Ethylene Plant and a Monoethylene Glycol (MEG) Plant.

Eagle will also implement a Dry-Low-NOx Burner (DLNB) retrofit on the Powerhouse C-Turbine Unit 4 in the Power & Utilities Unit prior to the start-up of operations of the new Ethylene Plant and MEG Plant. The DLNB retrofit will be implemented to decrease NOx emissions in order to offset NOx emission increases from the proposed project such that there is no net significant increase in NOx emissions that triggers Prevention of Significant Deterioration (PSD) review for NOx. 

Five permits are involved with the proposed Ethylene Plant Project, including one for the DLNB retrofit project.
