While establishing itself as a trusted source for engineering, PSE has spent 25 years providing engineering and design services in the petrochemical industry. PSE has worked with refineries, gas plants, chemical plants and in the plastics industry including many large companies such as BP, Chevron and Tesoro, as well as with small start-up companies making railroad ties from recycled tires, or recycling PET. Nonetheless, PSE is flexible and very capable to handle large or small projects. Whether technically advanced processes need analysis through Aspen Tech’s Hysys or if pipes and fittings need Finite Element Analysis, or if basic calculations or designs are needed, PSE provides the right resources to make that happen.
