Cogen Cleaning Technology uses 18 Atlas Copco Rental compressors to clean the pipes of the Russell City power plant, California, USA, during the final stages of the construction.
18 April 2013
The process of commissioning a startup requires cleaning the pipes throughout the facility. A big airblow requires 8 to 12 compressors: this project had 18 Atlas Copco PNS 1250 and XRVS high pressure compressors. Cogen also rented 9 Atlas Copco Hurricane boosters for the high pressure portion of this project, each with a coalescing filter pack and 14 fuel tanks.
The plan was to have 2 backup compressors but the 2 XRVS compressors allowed to reconfigure the manifold so both high and low pressure testing could be conducted at the same time.
On this job the chemical cleaning process was followed by a “hydrolaze” process: a high-pressure spray that knocks out debris stuck in the pipes.
It took a month for this project. “It’s about a week per system [18 on this job], but we combined the process to get it done faster,” Wakeem said.
“ Choosing Atlas Copco Rental as our partner in this project was a no-brainer. [Atlas Copco Rental was] critical in securing this project, providing their expertise all throughout the bid process. ”
After this a target [polished carbon steel plates shined to a mirror finish] was inserted into the line. When sufficient time had passed, the target was removed and checked for quality of air in the system. Targets at first are pitted and abrasive: when the targets show repeatedly clean, the process is finished. This project required 18 systems to be blown, each with different lengths of time. “You go into a project this size knowing there will be issues. We received very good support from Atlas Copco Rental that allowed us to continue to make progress.”
