Overview

Uhde offers its customers many years of expertise and experience in chemical plant engineering - from the execution of process studies to the handling of projects on an EPC basis.

We offer a highly competitive technology for the production of nitric acid in the range up to more than 2000 mtpd.

Based on customer-specific requirements an optimized process concept is developed, taking into account capital expenditure and operating cost. Both, mono-pressure and dual-pressure processes are available.

Plants can be designed for applications in fertilizer or explosives industries (usually approx. 60% nitric acid concentration), or for the chemical industry (up to 68% nitric acid concentration, azeotropic acid).

Technology Highlights:

• More than 130 references for all process variants since 1958, 23 references in the 21^st century

• High reliability and on-stream time

• Low emissions and colourless tail gas (EnviNOx^®, best available technology)

• High energy efficiency

• Long campaigns up to 12 months

• Up to date equipment referenced (e.g. NAMAX – the newest generation of an inline nitric acid machine train)

• Patented designs of key equipment

• Long lifetimes of plant e.g. by specially suited material selection

• Easy maintenance

• Proven cost-effectiveness

Uhde provides services from concept studies to turn-key plants, as well as operations and maintenance.
