Improving the Operation of Ammonia Synthesis Loops

Magnetite-based synthesis catalysts have formed the basis of ammonia synthesis. Operating experience using the latest ammonia synthesis catalysts is described in this article.

Inherent Safety application to ensure an ALARP

In general it is better to incorporate safety into design earlier, i.e. during design development, than later, when the design is finalised. This article discusses how the methodology can be applied to a conceptual design stage.

Energy efficiency improvements using emissivity refractory coating

By applying a “High Emissivity Coating” on the surface of the furnace walls, it is possible to increase the emissivity and thereby improve the thermal efficiency of the furnace box significantly.

Catalyst deactivation Common causes

The causes of deactivation are basically three-fold: chemical, mechanical and thermal. Some lose their activity after a few minutes, others last for more than ten years.
