Our engineers have the experience to take your initial ideas and turn them into practical equipment and process designs. We can help size a new pump or design a new processing unit. We can turn troublesome existing units into robust, state-of-the-art facilities with well-trained operators.

Our projects range from small pump and exchanger systems to large-scale greenfield processing units with advanced controls. We know that the best design is simple and easy for your operations staff to run it as intended.

We help our clients by finding the root cause of operation problems and determining the right process or equipment modifications that are simple and controllable.

Amine Study

A southern, heavy oil refinery undergoing an expansion needed to increase its amine processing capacity.  They wanted to achieve that goal by reviving equipment from an idled unit as much as possible.  Our engineers evaluated their expansion plans, determined the new amine requirements, and identified the modifications required for the idled equipment to meet those requirements.  We rated existing equipment to determine bottlenecks, specified tower internals to increase capacity, re-rated existing pumps, exchangers, and piping, and detailed changes to existing instrumentation for capacity expansion and process controllability.

Water Reclamation

Our client approached us with the challenge to reduce their municipal water costs at their machine wash facility by reclaiming spent wash water, treating, and reusing it in another part of their process.   The current technology for direct recycling and filtration systems suffers from maintenance headaches and excessive odor problems and is not an option.  

PTI engineers met with stakeholders to understand the unique details of their process, analyzed the reclaimed water samples, and developed a separation and treatment strategy to recycle this waste stream efficiently.  PTI’s engineers designed the process with the goal of using common industrial equipment to keep the system cost-efficient and minimize supply chain challenges for custom components.  

After completing the design and reviewing the 3D Model with our client, we fabricated the initial prototype in our Plano, Texas facility.  With the system in our shop, our engineers and shop personnel completed an initial function test and performance run before shipping the unit to our client’s facility.  

Once onsite, our engineers provided operator training and assisted with the initial start-up and full-capacity operation.  The unit is in operation and undergoing long-term performance testing.   Our client has targeted the system to become the standard water reclamation module for all their US-based facilities.
