Ammonia decomposition unit
2NH3 ----- 3H2 + 2N2
In the ammonia decomposition hydrogen production unit, liquid ammonia is used as raw material. After gasification, it is heated and decomposed under the action of catalyst to produce a mixture of 75% hydrogen and 25% nitrogen. Pure hydrogen with 99.999% purity can be further prepared by pressure swing adsorption.
● The principle is simple, the structure is compact, the area is small, and the operation is simple.
● Low investment, low energy consumption and low operation cost;
● It is widely used to meet the needs of most hydrogen use.
● Optimum design of furnace body, furnace gallbladder and electric heating wire for core components, and three-year maintenance under normal working conditions.
● Raw ammonia:
● pressure——～0.5bar
● The dew point——≤－10℃
● Satisfying the Standard-First Class of National Standard
● Product decomposition gas：
● pressure——～0.5bar
● The dew point——≤－10℃
● Residual ammonia——≤0.1%
● Decomposition gas volume——1～1000Nm3/h
● Note: For lower ammonia content and dew point requirement, NHP series ammonia decomposition gas purification device can be selected. Equipment below 30Nm3/h is standard without gasifier. The configuration of ammonia tundish and ammonia storage tank can be considered in atmospheric ammonia decomposition device to obtain more stable working conditions and lower energy consumption.
