Maleic Anhydride Expansion Project

Maleic Anhydride Expansion Project

Location: Geismar, La.

Client: Huntsman Corp.

Completion Date: 2009

Huntsman contracted Burns & McDonnell to perform preliminary design, cost estimating and site selection for the feasibility phase of the North American Maleic Anhydride Expansion Project, and to perform basic design, definitive cost estimating and procurement for the final definition phase of the project.

  • Preliminary design
  • Factored cost estimate
  • Site selection
  • Basic engineering
  • Definitive cost estimate
  • Procurement

The scope of work included the preliminary design of a 100 million pounds/year maleic anhydride plant using Huntsman’s fixed-bed/solvent recovery technology. Several sites were initially considered for the plant, and the plant design was customized for each site. Burns & McDonnell defined OSBL requirements and prepared a factored cost estimate for each site to assist in the site selection process. After Huntsman selected the site, Burns & McDonnell completed basic engineering and a definitive cost estimate for the plant. Burns & McDonnell also procured long delivery equipment during this phase of the project. 

The new facility will expand Huntsman’s North American maleic anhydride production capacity from 230 million pounds/year to 330 million pounds/year. The Huntsman technology produces maleic anhydride through the partial oxidation of normal butane over a vanadium phosphorus catalyst in a large, fixed-bed, molten salt-cooled reactor. The maleic anhydride is recovered in a solvent system and refined to finished product grade in a batch distillation system.

Burns & McDonnell has supported Huntsman’s maleic anhydride technology licensing program for over 14 years and has performed basic engineering on 12 facilities worldwide with a total maleic anhydride production capacity of over 1 billion pounds/year.
