Xylene BI Improvement
The scope of this project includes Phase 2, 3 and 4 services to modify operation of Xylene unit and allow the Bromine Index to improve. Re-routing was performed to clay treat Xylene Column overhead. Initially a +/-40% total installed cost estimate has been provided.
VaxonTM and PNA Unit Revamp
Complete project services for development of a 35MT lube oil reprocessing facility, including full basic conceptual frond end and detailed engineering services for installation of lube oil reprocessing unit in Denmark. Project included revamp of existing facility to provide lube oil reprocessing capability and procurement of equipment, supervision of module construction, construction inspection, commissioning startup support and ongoing plant engineering support.
Benzene Interconnection
The scope of this project was to install the necessary piping and resize the pump to transfer benzene between two plants using a spare interconnecting pipeline system. Onyx performed the engineering estimates, detailed design and construction support.
Lube Oil Reprocessing Plant
Provide engineering, construction and operations support for a 70MT per year lube oil reprocessing. Scope of project included full basic, conceptual, front end and detailed engineering services for a grass roots lube oil reprocessing plant in Al-Jubail Saudi Arabia. Project included all facilities and utilities. Scope also included providing procurement commissioning startup support and plant operation supervision. Project implemented licensed technology to reprocess used lube oil and provide virgin grade base oil with no waste streams. Project execution was similar to DBOOT process.
HOC Flue Cooler Replacement
