Design, Build, Operate

The three building blocks
of our mission.
Merging design, manufacturing
and experience in plant operations,
we offer comprehensive support from the earliest stage of conceptual design up to after-sales services.


We oversee all design stages, from feasibility studies to detailed engineering, to ensure that our customers are convinced that their multiple needs are best met from the earliest stages.

Feasibility study

The design of a new plant or equipment always requires taking into consideration multiple parameters, frequently unknown, especially when a new substance has to be processed. To obtain data, establish the design criteria, and to verify process reliability, we perform process simulations and testing, leveraging our multidisciplinary teams and R&D centre capabilities.
Collected data and information allow us to prepare technical & economical feasibility studies to ensure that our customers are convinced with the solution offered.

We can also provide equipment for rent when customers want to perform the tests themselves.

Design engineering

The design of a new plant or equipment always requires meeting multiple targets and analysing multiple parameters and criteria. We are able to leverage our balanced multi-discipline engineering team to meet these requirements, based on our robust and consolidated chemical processing and mechanical engineering knowledge, integrated by effective automation, instrumentation and piping design capacities.
Acting as a partner, we work closely with our customers from the earliest stage of the feasibility study and conceptual design up to detailed engineering.
