Rosnik provides process engineering services, operational excellence and consulting support for Capital projects across the chemical, petrochemical, refining, oil & gas and energy sectors.
Our process engineering consultants support projects from early development and feasibility through FEED and detailed engineering, helping project teams establish process requirements, develop engineering deliverables and coordinate process design with other engineering disciplines. Rosnik also assists organizations in attaining operational excellence by helping improve processes, reduce inefficiencies, optimize operations, and achieve more consistent, cost-effective performance.
Whether you require dedicated process engineering consulting services or process engineering support as part of a broader engineering package, our scope can be aligned with your project’s phase, technical requirements and deliverables.




Process engineering is a critical component of successful industrial and CAPEX projects, connecting process requirements with equipment, piping, instrumentation and other engineering disciplines. Rosnik provides process engineering services and consulting support that can be integrated into broader engineering solutions across different stages of a project. Our process engineering consultants support project teams with process design, heat and material balances, PFDs, P&IDs, process calculations, equipment design inputs, utility requirements and other process engineering deliverables based on project scope. Whether the requirement is early-phase engineering, FEED development, detailed engineering or support for an existing facility, our process engineering expertise helps establish a clear technical basis for multidisciplinary engineering.
Process engineering is an essential part of integrated engineering solutions for industrial and CAPEX projects. It translates project objectives and operating requirements into a defined process basis that can guide equipment selection, piping, instrumentation and multidisciplinary engineering.
At Rosnik, process engineering can be integrated with our broader engineering solutions according to the project phase and scope. Our process engineering team supports clients in developing and reviewing process requirements, engineering calculations, process documentation and technical inputs required for subsequent engineering activities.
By integrating process engineering with other engineering disciplines, project teams can maintain consistency between process requirements, equipment design, piping, instrumentation and overall project execution.
Rosnik provides process engineering consulting services for clients developing, expanding, modifying or optimizing industrial facilities.
Our process engineering consultants work with project teams to understand the technical requirements of the facility, project phase and process scope, and develop the appropriate engineering inputs and deliverables.
Depending on the project requirements, our process engineering consulting scope may include:
The consulting scope can be provided as a dedicated process engineering assignment or integrated with Rosnik’s broader engineering services.
Chemical plant design requires coordinated engineering across process, mechanical, piping, electrical, instrumentation and other disciplines.
Rosnik can support chemical plant development, expansion and modification projects through process engineering and related multidisciplinary engineering services.
Our process engineering team can establish the process requirements and technical inputs needed to support subsequent plant design activities.
Refinery and petrochemical projects require close coordination between process engineering, equipment, piping, instrumentation, utilities and other engineering disciplines.
Rosnik provides process engineering support for refinery and petrochemical projects, including new facilities, expansions, modifications, revamps and other CAPEX initiatives.
Process engineering establishes the technical foundation for safe, reliable and efficient plant operation. A well-defined process design can help project teams evaluate operating requirements, equipment performance, utilities, process constraints and opportunities for improvement before they become downstream engineering or operational challenges.
Rosnik’s process engineering consulting services support clients in evaluating and developing process configurations with operational requirements in mind. Our work can include process analysis, process optimization, equipment design inputs, utility requirements and engineering studies that support informed project decisions.
Process engineering can contribute to operational excellence by helping process operating teams:
For new facilities and existing plants alike, process engineering provides the link between project objectives and the practical requirements of plant operation. By addressing process requirements early and coordinating them throughout the engineering lifecycle, project teams can develop solutions that are aligned with both project execution and long-term operational objectives.
A process engineering consultant can support project teams with:
