Project MagSUR with Fluidised Bed Calciner


Project Overview

The objective for this project was to provide a general description of two different processes for the crystallisation of magnesium sulphate (MgSO4), mainly the conventional evaporative crystalliser, and a high temperature crystalliser. In addition, Sargon Engineering provided a description of the downstream processes from the Fluidised Bed Calciner for the production of magnesia (MgO) to the acid plant. A comparison of utility requirements, such as steam, power and water was provided for both models.

Solutions Delivered

By way of thorough literature review, Sargon Engineeering obtained data to form appropriate design criteria, which would then inform the process simulation and associated documents (flow diagrams, stream tables & mass balance). A full METSIM model of both crystallisation scenarios was prepared, and then summarised as detailed Block Flow Diagrams (BFD’s). Commentary on both processes was provided in the final report, with careful consideration given to power consumption and operating efficiency.

Notable Results

Sargon Engineering was able to clearly communicate the requirements for two very complex processes, in both written and graphical form, allowing Vale to understand the process requirements for the two options, along with the anticipated virtues or drawbacks of both designs.
