From first refineries to future facilities

We’ve designed systems to handle all hydrocarbon components and chemicals found in a refinery, from crude delivery through to blending and shipment of finished products. As demand for energy grows, we continue to develop experience with the facilities of the future. In addition to upgrade, expansion, revamp, and de-bottlenecking activities for hydrocarbon production and processing units, we also have extensive experience in turnaround maintenance activities.
