Nitric Acid - Process Description

Weatherly has developed the WEATHERLY Nitric Acid plant design with low capital cost, high ammonia conversion, low catalyst cost, low maintenance cost, and high energy efficiency. Weatherly's high pressure mono-pressure design's low operating cost is always competitive with the dual pressure process and depending on specific plant location circumstances, it may be superior. The WEATHERLY Nitric Acid plant design also improves the advantage of lower capital cost for the single pressure process.

Characteristics of the high pressure mono-pressure process:

  • Results in smaller plant equipment.
  • Minimizes area requirements for the plant site along with a vertical arrangement.
  • The vertical design and equipment arrangements also minimize piping runs and expansion problems in the high temperature gas piping.
  • The facility is carefully designed to provide ample access for maintenance.
  • High energy recovery options can be arranged in various combinations to minimize plant operating and capital costs.
  • Consistently high ammonia conversion efficiency and long gauze life.
