Highlights of the SD Maleic Anhydride (MAN) process include:

• In MAN licensing business for over half a century. First plant licensed in 1954.
• Over 40 licensed plants worldwide.
• Fixed bed reactor design for n-butane feedstock.
• Now offering a new, patented, high efficiency Series Reactor design:
  • with lowest cost-of-production (COP)
  • favorable NPV analysis
  • adaptable to solvent or aqueous recovery system
  • suitable for process integration with BDO/THF process
  • with reduced environmental impact
• A leader in feed-stock conversion projects; from benzene to n-butane.
• Experienced in capacity expansion projects.
• Experiences in revitalizing old phthalic anhydride (PAN) reactors for MAN production.
• Proprietary catalyst that demonstrates high selectivity and long life

With the advent of large size fixed-bed reactors, the Series Reactor design could offer a plant capacity of 70 - 80,000 mtpy of molten MAN in a single train (two reactors operating in series).
