Stepwise approach of revamping
There are different drivers for revamping an urea plant, each with their own stakeholders and limitations. The limitations are usually dictated by the ammonia plant and utilities (macro scale) as the order of magnitude of the investment and the impact on the capacity increase of a chemical complex is higher compared to the urea plant. When a revamp in an urea plant is required, the most optimal result can be achieved when a long-term planning is included in the plan of approach. By thinking ahead the planning can be made as such that the revamp design can be executed stepwise fitting in the company’s investment plant and aligned with the long- and short term company vision.
