Arveng develops Feasibility and Conceptual Studies as an instrument that serves to make decisions in the evaluation of a project. It is formulated based on information that has the least possible uncertainty to measure the chances of success or failure of an investment project. These studies are fundamental since they will set the standard in the following phases of the project, mainly during Basic and Detail Engineering.

After setting the objectives of the project and defining the applicable regulatory framework according to the location and type of project, we focus on the following aspects:

Evaluate and establish the technologies used in the project

Define critical elements with the greatest impact on the project

Evaluation of associated strategic, economic and operational risks

Criteria for the economic evaluation and profitability calculation

Comparisons are made during the conceptual study phase to evaluate the technologies and mitigate the risk. First, the available information is carefully examined to confirm the design of the processes and to challenge the assumptions in order to guarantee their optimization, from a technical, economic and safety point of view. Finally, constructability is studied and cost analysis are carried out that provide the key conclusions for the following phases.


Some of the activities and scope during the Conceptual Engineering phase are...

  • Preliminary process studies using simulation software

  • Process description and operation philosophy

  • Pre-design of main equipment

  • Flow diagrams | cause-effect matrix of processes

  • Constructability analysis of the main equipment

  • Economic evaluation and profitability calculation
