As part of a significant project to upgrade a client’s two existing atmospheric treating batteries so as to ensure safe and continued operation of the facility for 15 years, Vista conducted the FEED and detailed engineering for a project to replace and extend a non-guyed Once-Through Steam Generator stack in order to address corrosion issues and to increase plum dispersion.
Vista designed a structural frame for a 42.4-metre (140-foot) stack to avoid the use of guy wires as well as the process to erect the structural steel within a building that had no structural or architectural drawings or plans. The stack was erected in a short time and required only a minimal amount of downtime for the facility.
Vista’s work on this replacement of an atmospheric treating train with a capacity of 1,800 m3/day emulsion, 1,500 m3/day dry crude included the following:
- Demolition of existing facilities
- Additional truck pit dump tank and new charge pump
- Wash and settling tanks with process building
- Two 3,000 barrel sales oil storage tanks
- Modifications to three truck pit dump tanks and three sales oil storage tanks
- Sales oil off-loading facility
- Tie-ins to existing facilities and utilities
