Sierra Chemicals is a preferred vendor for many major oil companies. In 2018, ExxonMobil spotlighted Sierra Chemicals in their sustainability report based on our cleaning work in two of their Texas refineries.
























"They were professional, courteous and did everything that was asked of them from a safety and quality aspect. The jobs were planned appropriately and went smoothly. The follow up call after the work was complete was good as well. I would recommend Sierra Chemicals to anyone who has fin fan cleaning needs."
"Our 2021 turnaround was one of the largest midstream TARs in 2021. Sierra used 2D/3D waterjetting technology to clean some of our most difficult and largest vessels in our plant. From Sierra's clean-in-place chemical circulations to their waterjetting technology, we were pleased with results from their cleaning techniques. Sierra not only finished within schedule but under budget."
"Sierra Chemicals was our first call when we needed help with a plate and fin exchanger that was plugged up. Our exchanger was completely clogged with mol sieve dust and heavy hydrocarbons. Sierra had the system cleaned & flushed with methanol and turned back over to us in just 12 hours. Thanks to Sierra's chemical cleaning, we were able to extend the lifespan of the exchanger and avoid a costly unplanned shutdown — saving over $4 million."
"Being that every location was different, Sierra did a fantastic job understanding all needs of the project. They took care of providing access to elevated areas, providing access to a fresh water source and the containment and disposal of the spent fluid. Sierra conducted pre and post-service calls with us to make sure all portions of the project were handled properly and came in under budget. We were proud to nominate them as a supplier of the year in result of their performance."
