Specialty Chemicals Company
On-Site Cryogenic Quality Nitrogen Generation
In this project, our engineers supported the installation of an on-site system that reduced our client’s nitrogen generation costs by 40%.
This Specialty Chemicals Company uses unique processes to develop and deliver quality chemical products to their customers.
This client was spending over $1 million per year in liquid nitrogen for tank process equipment inerting. A process study was completed that demonstrated that nitrogen generation costs could be reduced by 40% by generating nitrogen on-site. The project goal was to clear a site at the client’s existing facility and to install a new foundation and electrical transformer for a vendor-supplied, cryogenic nitrogen system. The age of the plant and the narrow footprint of the selected space presented significant design challenges. Another challenge was the need to replace the plant’s existing liquid nitrogen tank while keeping the existing nitrogen facility in service.
Our engineers worked closely with site operations, safety personnel, and equipment vendors to overcome existing challenges, including the adjustment of the equipment layout to fit the narrow site footprint.
This project was a complete success, and the process was repeated at another of this company’s plants where pressure swing adsorption was installed without cryogenic distillation due to a less stringent requirement for nitrogen purity. Reduction in the cost of nitrogen for this plant was 50%.
