Engineering and Design

Dube Engineering has professional engineers (PE) on staff to help with your process engineering and design needs. Our product development engineers can help in many ways including:

  • Process Engineering and Design
  • Mass and energy balances
  • Equipment selection
  • Instrumentation selection
  • Layouts
  • PIDs (Piping and Instrument Diagram)

If you are at the early stages of the process design, Dube Engineering will first start helping by getting your ideas organized onto paper. From there, we can lead you through the scaleup process including:

Proof of Concept


Proof of concept can be done at several places along the product development path. It really depends on how you are growing your resources and your definition of “proof”. Some people just need proof at a gram(s) scale for themselves and others need 100+ kilograms as proof to a customer.

Bench Scale


Larger than lab scale, and starts to require some specific equipment. Depending on safety and what was learned from the lab scale, outputs are kilogram range with samples for full lab testing and possibly samples to a customer.


Lab Scale


Small quantities (grams) of materials, usually manipulated by hand (if possible) to keep cost at a minimum. The output is usually a sample just large enough for qualitative and possibly quantitative feedback.

Pilot Scale


Fully designed and operational pilot scale that mimics your full-scale plant process. Outputs would include samples at 10% to 60% of full scale, and allow for full lab test and large samples to the customer for review. From this, final changes and adaption can be made before finalizing production plant design.

Perspective

Our specialty engineering design company truly has your best interest at heart during all times of the engineering process. Always keep in mind that all processes scale different, and you should consider several factors when approaching your next engineering process phase including:

  • Safety - How well do you understand the process, is there a chemical threshold you want to stay below, etc.
  • Requirements - Customer wants, material quality, etc.
  • Complexity of process - Multiple reactions vs. single reaction, number of physical steps in the process, etc.
  • Cost - Get the most from your investment, does a 50% increase cost you 10% more capital or 110% more capital.
