A "grassroots refinery" refers to the construction of a new refinery from the ground up, starting with an empty site and building all the necessary infrastructure and processing units. The "Concept to Commissioning" phase encompasses the entire lifecycle of the project, from initial idea and planning to the final operational startup. This journey involves various stages, including design, engineering, procurement, construction, pre-commissioning, commissioning, and finally, the operational start-up and performance testing.
