The problem solvers and opportunity creators of process optimization

Process engineering is a strength at C&I. We have a long and successful track record of solving the most difficult technical issues, whether they are for grassroots refinery projects, expansions or revamps, turnarounds, smaller maintenance projects, or simply ongoing technical support. Our senior process specialists have decades of experience addressing all forms of refining processes. They recommend, design and implement modifications to improve unit efficiency, profitability, operating stability, OSHA-PSM compliance and safety.

C&I performs process audits, economic studies and range of different types of evaluations. We utilize various modeling programs to simulate the processes of new and existing units.

Our expertise allows us to help tech service departments perform root-cause discovery for equipment failures, then formulate an effective, permanent, solution.

We also like to solve problems others have given up on. There isn’t much our team hasn’t seen, but we’re always up for a new challenge.

ISBL Expertise

Given the experience mentioned above, our teams are especially adept at planning and executing ISBL projects. We know what questions to ask, what traps to run, what obstacles might pop up along the way. Our people know instinctively to design not just for steady state operations, but also for the shutdowns and restarts and other eventualities when the unforeseen occurs. That is why refineries have called upon us again and again to handle their critical ISBL jobs.

High level collaboration up front leads to elegant, cost effective solutions.

Pre-Conceptual Studies

When we embark on a project, our process group teams with those in our other engineering disciplines to determine what we need to do to meet the client’s end goal. We decide what we can change to deliver what the client wants. At this stage we are essentially defining possibilities.

Conceptual Studies

Here we build the business case, evaluating proposed process solution options and running numbers. Once we have proof of concept and a high level estimate, we can help the client make the decision to move forward or not.

Feasibility Studies

We analyze our options and narrow our focus to the best solution for our client. The estimate we generate here is tighter than the conceptual stage.

Refinery Shutdown and Crude Unit Upgrade
For a facility in the Midwest, this project involved upgrading a crude unit to increase capacity by 20%. The project entailed detail design and approximately 60 sub projects required for a three-week turnaround. The schedule was three months in duration leading up to the outage. Projects involved process design, piping design, structural steel and foundation design, electrical engineering, construction cost estimating and planning, and field construction support.
Ultra Low Sulfur Grassroots Distillate Hydrotreater
C&I performed a feasibility study to determine the modifications necessary to produce Tier 2 diesel fuel for a Midwest refinery. The study consisted of evaluation of catalyst vendors, block flow diagrams, process modeling, process flow diagrams, preliminary P&IDs and equipment data sheets. We looked at several innovative technologies for sulfur removal and disposal before settling on a conventional amine-sulfur plant design, which was designed by C&I.
Natural Gasoline Processing Study
C&I developed a definition-quality estimate for replacing existing PFS charge pumps to increase charge rate to 26,000 BPD, install a new preheater in the PFS charge line, and replace PFS bottoms pumps to meet the 26,000 BPD design rate.
