Gasification is a system widely used by industry, and its commissioning should be evaluated with caution. A well-executed commissioning is fundamental for reducing labor cost and time, for predicting possible problems during the starting process and for the initial adjustments of the industrial systems. In this work, two commissioning processes were analyzed and, from them, a simplified macroprocess was generated with the main equipment. This was intended to better understand the gasification process and could assist in commissioning planning.
