Basic engineering, FEED, Concept study projects:​

Concept study projects:

The conceptual design is a study phase in which ideas and possibilities are evaluated. This phase results in a basic process concept, a preliminary schedule and a rough cost estimate. At weLITEN, we evaluate the process to assess its technical feasibility and economic viability for developing project scope as well as providing a well defined starting point for a more detailed process design.​

BASIC ENGINEERING:​

The basic engineering services offered by weLITEN consist of core documentation of projects, including process flow diagrams, heat & mass balances, piping and instrumentation diagrams (P&IDs), control & operational philosophy, basic equipment sizing, equipment specifications, conceptual equipment layout, etc.​
