Plants Geleen

Ammonia is produced through the synthesis of nitrogen and hydrogen. Hydrogen is produced from low-sulphur, high-calorific natural gas with a low calorific value of approximately 37.4 GJ/nm3, using a steam reforming process. Nitrogen is sourced from atmospheric air.
 
OCI Nitrogen has two world-scale production plants at Geleen with effective capacities of 560kt and 570kt per year, respectively. State-of-the-art Bechtel and Kellogg technologies allow us to produce ammonia in an energy-efficient manner.
 
The controls for the two plants are fully integrated and monitored from a single control room using the latest technology control system, providing high production reliability. Both plants are certified to ISO 9001 standard.
 

Storage Geleen

The ammonia produced in Geleen is stored in two atmospheric cooled (-33°C) ammonia storage tanks, each containing 25,000m3 each, and a pressure storage sphere of 2,200m3. At the Geleen site, ammonia is supplied through a liquid ammonia distribution grid to which the ammonia storage tanks are connected. The grid is protected by several methods, for example acoustic alarms to detect and limit the effects of potential leaks. Supply to external customers is through leased rail cars that directly connect the Geleen site to customer’s production sites. The Geleen site has fully integrated rail loading facilities and a daily loading capacity of 24 rail tank cars.
 

Argon

Sale of argon to industrial gas companies is through multi-year take-or-pay contracts. OCI Nitrogen stores argon at its Geleen site in a storage tank at -186oC.

OCI Terminal Europoort

OCI Nitrogen is the owner of two ammonia storage tanks at Europoort (Rotterdam). These meet the highest standards for safety and environmental protection. Each tank has a capacity of 15,000 tons of refrigerated ammonia. OCI Terminal Europoort has a permit to receive up to 0.60 mtpa of ammonia and deliver up to 0.55 mtpa. 
 
The assets at OCI Terminal Europoort include:

 

  • Two large ammonia storage tanks with a capacity of 15,000 tons, protected by a surrounding concrete wall;
  • Two ammonia loading pump units transporting ammonia through pipelines to loading platforms;
  • Two ammonia heat exchanger units for heating ammonia for rail and truck loading;
  • Two ammonia gas/liquid conversion compressor/condenser units for converting excess gas to liquid;
  • One ammonia cooling unit to keep ammonia at -33°C with sump pit operated by two pumps;
  • Aqueous ammonia blending unit to produce aqueous ammonia up to a max. concentration of 33.5%.
