KBR's Purifier™ Ammonia Process combines the following proprietary technologies to yield an extremely reliable, robust, low-energy plant:
With KBR's cryogenic Purifier™ syngas technology, you receive a lower-cost, more robust processing route to high-purity synthesis gas in ammonia manufacturing plants. The proprietary, front-end process cryogenic purification technology simultaneously removes impurities (i.e., methane, argon) from synthesis gas by washing it with excess nitrogen while adjusting the hydrogen to nitrogen (H2/N2) ratio to 3:1.
Providing a clean, dry, make-up gas to the synthesis loop and simple and precise H2/N2 ratio control, Purifier technology offers benefits to the entire operation in several key areas:
The Purifier™ process system is a simple design consisting of three pieces of equipment: a feed/effluent exchanger, a column with a built-in condenser and an expander. All items and the connecting piping are welded and enclosed in a perlite-insulated cold box. Specific equipment design features include:

For conventional magnetite synthesis loops, KBR offers its horizontal ammonia synthesis converter. Inter-stage coolers between the catalyst beds provide for maximum conversion and heat recovery.
For conventional magnetite ammonia synthesis loops, KBR offers its horizontal ammonia synthesis converter. The converter contains two or three reaction stages, each with vertical downward flow in the magnetite catalyst beds. Intercoolers are provided between the catalyst beds for maximum conversion and heat recovery.
The catalyst basket is easily removed from the converter shell for catalyst loading and unloading. The basket can be rolled out of the horizontal converter vessels on tracks, thus avoiding the need for scheduling and erecting a heavy and expensive crane for periodic maintenance.
