Fertilizers

Mass transfer and separation across the fertilizer value chain — ammonia synthesis, urea, nitric acid, ammonium nitrate and phosphates. Depending on the application, EVERFIBRE can be used for acid mist services, EVERPACK for absorber columns and EVERFRAC for gas–liquid contacting duties.

Equipment for fertilizer process duties

Fertilizer plants involve a range of absorption, gas–liquid separation and mist-removal duties. Evergreen develops internals for new equipment and revamps, with designs suited to the process conditions and available column or vessel space.

Equipment selection considers capacity, pressure drop, liquid carry-over and service-specific requirements such as corrosion, solids loading, crystallisation and fouling. Materials are selected for the actual fluid composition, concentration and temperature. Engineering support can include hydraulic design, assessment of existing internals, revamp recommendations, and installation supervision, with the scope agreed to suit project requirements.

Process performance guarantees can be offered for selected applications, subject to agreed feed characteristics, operating conditions, and performance criteria.

Selected fertilizer applications

Ammonia Plant — Gas Treatment & Separation

Carbon dioxide absorption and solvent regeneration during synthesis-gas preparation, together with gas–liquid separation duties in the ammonia plant. Trays, packings, mist eliminators, and internals are selected for the specific process conditions.

  • EVERFRAC trays
  • EVERPACK packings
  • EVERMESH mist eliminators
  • EVERGREEN column internals

Urea Plant — Mist Removal

Mist-removal duties in urea solution concentration and associated gas-scrubbing systems. Mist eliminators can be evaluated for liquid carry-over control, with consideration for solution chemistry, temperature, crystallisation, and fouling.

  • EVERMESH mist eliminators
  • EVERON vane mist eliminators

Nitric Acid — Absorption & Mist Removal

Absorption of nitrogen dioxide in water to produce nitric acid. Trays and column internals support gas–liquid contact, while mist eliminators remove entrained acid droplets. Gaseous NOx treatment is a separate duty from acid-mist removal.

  • EVERFRAC trays
  • EVERFIBRE fibre-bed mist eliminators
  • EVERGREEN column internals

Ammonium Nitrate — Prilling & Exhaust Treatment

Treatment of exhaust containing ammonium nitrate particles and aerosols from prilling operations. Fibre-bed mist eliminators can be evaluated for fine-aerosol collection, with mesh or vane eliminators for scrubber droplet carry-over where appropriate. Selection considers particle size, loading, and deposition potential.

  • EVERFIBRE fibre-bed mist eliminators
  • EVERMESH mist eliminators
  • EVERON vane mist eliminators

Phosphate Fertilizers & Associated Acid Plants

Gas-scrubbing and mist-removal duties in phosphate fertilizer production and associated acid plants. Packings and mist eliminators are selected for the gas composition, acid chemistry, solids loading, and corrosion conditions. Sulphuric acid plant applications are covered separately.

  • EVERPACK packings
  • EVERMESH mist eliminators
  • EVERON vane mist eliminators
  • EVERFIBRE fibre-bed mist eliminators
