NORAM Engineering and Constructors Ltd. products

MNB is a feedstock that, via intermediates aniline and MDI, ultimately becomes polyurethane. NORAM’s adiabatic aromatic nitration technology has been implemented for customers all over the world including the world’s largest MNB plant.  NORAM has a broad range of experience in meeting our clients’ local requirements. We continue to innovate and provide solutions for new challenges, which has resulted in a comprehensive suite of patents.

Our proprietary Nitric Acid Concentration process is characterized by its energy economy, minimal losses of nitric acid and sulfuric acid, and with the integration of our NO_x Recovery technology, almost 100% yield of nitric acid. Pre-heating of weak nitric acid feed reduces the consumption of medium to high pressure steam, and shifts heat exchanger surface area from tantalum to less expensive materials like zirconium and various stainless steel alloys specifically developed for nitric acid service. NORAM’s extensive knowledge of glass-lined piping systems ensures a safe and robust piping design with minimal maintenance costs. For specialized applications where organics-laden nitric acid streams are recycled to the NAC, NORAM draws on its extensive nitration experience to ensure safe designs in which organic compounds are unable to accumulate and form unstable mixtures.
