Process Engineering Design Services

Whether you’re stepping into a project at front-end engineering design (FEED) or picking up detailed design mid-stream, Cognascents Consulting Group provides process engineering design support that adapts to whatever phase your project is in.

When Clients Engage Us

Common reasons organizations engage process engineering design services

Organizations typically engage Cognascents for process engineering design support when they are facing:

▸A capital project that needs process engineering support at any phase, from concept through commissioning
▸Internal engineering teams stretched too thin to carry a project through detailed design
▸A FEED package that needs independent review before sanction
▸Process flow diagrams, heat and material balances, or equipment sizing that need to be developed or updated
▸A brownfield modification requiring process design integrated with an operating unit
▸Commissioning support to bridge the gap between design and startup
Our Approach

Process design support that meets your project where it is.

Every project phase, from conceptual design through commissioning, has a different set of deliverables and a different level of technical definition — process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), heat and material balances, equipment sizing, and specifications. Cognascents’ engineers step into any phase and carry the work forward without starting over.

Step 01

Conceptual & FEED Support

Conceptual & FEED Support

We develop or review process flow diagrams, heat and material balances, and equipment sizing to establish the technical basis and investment-grade cost estimate for your project.

Step 02

Detailed Design

Detailed Design

We finalize plans, specifications, and design deliverables to the level of definition needed for procurement and construction, coordinating closely with your project team throughout.

Step 03

Construction & Commissioning Support

Construction & Commissioning Support

Our engineers stay engaged through construction and commissioning, resolving field issues, supporting startup, and confirming the process performs the way it was designed to.

Engineers Who Understand the Whole Process, Not Just Their Piece

MULTI-DISCIPLINARY EXPERTISE
Engineers Who Understand the Whole Process, Not Just Their Piece

Our team brings process engineering, process safety, and asset integrity perspectives to design work, so decisions made early don’t create problems downstream.

We Step In Wherever Your Project Needs Us

FLEXIBLE PROJECT ENTRY
We Step In Wherever Your Project Needs Us

Whether your project needs support at concept, FEED, detailed design, or commissioning, our engineers adapt to the phase and the existing project basis rather than requiring a restart.

Design Work That Accounts for the Operating Unit Around It

BUILT FOR BROWNFIELD REALITY
Design Work That Accounts for the Operating Unit Around It

Much of our design work happens alongside a running facility. We design with the operational constraints of your existing unit in mind, not just the new scope.

What You Gain

A process design that holds up from concept through startup.

Good process design pays off long after the project team has moved on. Cognascents builds designs meant to perform in the field, not just on paper.

OPTIMIZED PROCESS PERFORMANCE

Designs built around efficiency, not just feasibility

We identify opportunities to improve throughput, reduce energy consumption, and cut waste as part of the design process itself, not as an afterthought.

DESIGN-STAGE SAFETY

Hazards addressed before they’re built into the plant

Safeguards, hazard analysis, and risk assessment are part of our design process, reducing the safety gaps that are far more expensive to fix after construction.

STREAMLINED PROJECT EXECUTION

Fewer surprises during construction and commissioning

Thoughtful equipment selection, layout, and material handling decisions at the design stage reduce rework and downtime later.

SCALABLE, FUTURE-READY DESIGN

Designs that accommodate the next expansion

We design with future growth in mind, so your process can adapt as demands change without a full redesign.

Cognascents connects process design to the modeling, procedures, and safety review it depends on.

THE MODELING BEHIND YOUR DESIGN DECISIONS

Process Simulation & Modeling Services

Accurate simulation is often the foundation of a sound process design. We build and validate process models to support design decisions with data, not assumptions.

THE PROCEDURES YOUR DESIGN ENABLES

Operating Procedure Generation

A new or modified process needs procedures that reflect how it’s actually meant to run. We carry design intent through to the procedures operators will use.

THE SAFETY REVIEW YOUR DESIGN NEEDS

Process Hazard Analysis (PHA)

New and modified processes require a PHA before startup. We help make sure the hazard review keeps pace with your design schedule.

PROCESS DESIGN QUESTIONS, ANSWERED DIRECTLY

Frequently asked questions about process engineering and FEED design

What is front-end engineering design (FEED)?

FEED is the project phase that converts a selected concept into a defined technical basis — PFDs, preliminary P&IDs, heat and material balances, equipment sizing, and specifications — sufficient to support an investment-grade cost estimate and a sanction decision. Weak FEED definition is the most common root cause of capital project overruns.

What does a process engineer deliver at each project phase?

Concept: screening studies and feasibility-level balances. FEED: PFDs, heat and material balances, equipment sizing, and design basis documents. Detailed design: issued-for-construction P&IDs, datasheets, and specifications. Commissioning: startup support, field issue resolution, and performance confirmation. Each phase builds on — and is only as good as — the one before it.

Can you join a project mid-stream?

Yes. We routinely enter at FEED, detailed design, or commissioning, working from the existing project basis rather than forcing a restart. The first step is always the same: verify the technical basis we’re inheriting before building on it.

How is brownfield design different from greenfield?

Brownfield design must integrate with a running unit: tie-ins, turnaround windows, existing equipment limits, relief system capacity, and management of change requirements all constrain the design space. A design that ignores those constraints is a construction problem deferred, not solved.
