Actemium UK provides process engineering from early concept and process definition through to detailed design and operational support.

Whether developing new infrastructure, increasing capacity or modifying an existing plant, effective process engineering starts with understanding what the operation needs to achieve and the conditions in which it needs to perform.

We develop solutions around your process requirements, with safety, efficiency, reliability, and the long-term operation considered from the outset.

From individual specialist support to multidisciplinary engineering for complex programmes, our expertise can scale around your requirements.

From process concept to detailed engineering

Good process engineering provides the technical foundation for the disciplines that follow.

Our engineers can help establish the design basis, understand material and energy flows, define equipment requirements, and develop the documentation needed to progress a process from initial concept towards detailed engineering.

As the design develops, process requirements can be integrated with mechanical, piping, instrumentation, electrical and control requirements. This helps identify interfaces earlier and ensures equipment and systems are designed around a collective understanding of how the process needs to perform.

For modifications to existing facilities, this approach also allows the proposed process to be developed around existing assets, available space, operational requirements, and other site constraints.

Integrated process engineering

Process engineering rarely exists in isolation.

Actemium UK can bring together process, mechanical, piping, CE&I, automation, engineering substantiation, and specialist analysis expertise around your project.

Working with one multidisciplinary engineering partner can reduce interfaces between disciplines and improve coordination as the process moves from definition into detailed engineering and delivery.

This helps create solutions that are not only technically robust, but practical to install, control, operate and maintain.

Process Engineering FAQs

  • What is process engineering and what does it include?

    Process engineering defines how an industrial process needs to operate, and the equipment, systems and controls required to achieve it. Our capability includes Basis of Design, Process Flow Diagrams, mass and energy balances, P&IDs, operating philosophies, equipment sizing and process and instrumentation datasheets.

  • When should a process engineer be involved in a project?

    Process engineering should ideally be considered early, particularly when developing a new process, modifying existing plant, increasing capacity, or changing operational requirements. Early involvement helps establish the design basis and identify process requirements and interfaces before detailed engineering progresses.

  • What is the difference between a PFD and a P&ID?

    A Process Flow Diagram (PFD) provides a high-level representation of the main process flows, equipment, and operating conditions. A Piping and Instrumentation Diagram (P&ID) provides greater detail about piping, equipment, instrumentation, and control requirements.

  • Can Actemium UK support modifications to existing process plant?

    Yes. Process engineering can be developed around existing assets, infrastructure, and operational constraints. Site and asset information can be considered alongside the process requirements to develop a practical approach to plant modifications and upgrades.

  • Can process engineering be integrated with automation and control?

    Yes. Actemium UK’s process, CE&I and automation expertise can be brought together to consider instrumentation, control, and automation requirements alongside the process design, reducing interfaces between disciplines.

  • Can Actemium UK provide multidisciplinary process engineering support?

    Yes. We can bring together process, mechanical, piping, CE&I, automation, substantiation, and specialist engineering expertise, either as an integrated team or to provide individual specialist support.
