Special ball valves for extreme conditions: Innovative conversion of an ammonia factory.

Innovative conversion of an ammonia factory

Special ball valves for extreme conditions ensure energy efficient and economical production

From 2012 to 2013 Yara Germany realized a comprehensive process optimization at the plant in Brunsbüttel. The ammonia factory is worldwide unique: both gasification lines can either be run on natural gas or oil. One component are the 5“ shut-off ball valves from Hartmann Valves. These are especially designed for the challenging combination of pure oxygen, steam and high temperatures. All customer demands have been fulfilled above-average. The energy efficient production secured the economic future of the facility.

Hartmann has the reputation being known as the “Mercedes“ among the valve suppliers. For this important conversion we have made the decision for a high quality solution!
