ESPINDESA participates in the different specialized magazines and annual Conference/Meetings in its fields of activity, by publishing different subjects related to the technologies which are considered of general interest. Below, it is collected a selection of some of these publications:

A Welcome Adaptation

Article presented in the WORLD FERTILIZER magazine, September 2021 issue, looking at how heat exchanger design can be adapted for use in nitric acid units to achieve energy savings.

A Digital Twin

Article presented in the WORLD FERTILIZER magazine, September 2018 issue, in collaboration with INPROCESS (Spain), to present a dynamic tool (OTS) that acts as a Digital Twin of a real Nitric Acid Plant, providing End Users with a training tool valid for engineers and operators.

The Challenge of Modular Design

The challenge of Modular Design for a Nitric Acid and Technical Ammonium Nitrate Project in Australia, due to remote site location in order to reduce construction manpower costs.

Harnessing Power from Plant synergies

The installation of a power generator linked to the Nitric Acid Compressor Train to produce enough energy to operate the ANNA Complex as an island and improvements in Ammonium Nitrate neutralizer reactors.

Highlights in Production Costs of the Dual Process for Nitric Acid

A sound comparison of the unitary consumptions, through a complete year, between the Dual Process for Nitric Acid manufacturing in front of the Mono Pressure Process, in the case of large plants.
