Madagascar H2S Plant

C&I was excited to work on this world class project to support one of the largest nickel project’s ever constructed. Our unique H₂S process is utilized to support mining operations, including this site which is the largest in the world for H₂S production. We joined this project during the construction phase and spent almost four weeks evaluating their building processes and pointing out areas of concern. From there, we created a punch list and started working on the design package. We returned on-site to support start-up and commissioning alongside a multi-cultural workforce. With many language barriers, our team had to be adept at communicating, training, and interpreting signs and materials.

Dimethyl Sulfide Grass Roots Plant

C&I is excited to have provided design for the unique process of converting waste H₂S from the refinery process to Dimethyl Sulfide (DMS), one of the only plants in the world. When our client began expanding their plant to process heavy sour crude, they were faced with additional H₂S to treat. C&I assisted with a cost comparison between options including installing a third Claus/Tail Gas Treating unit, versus converting to DMS. The neighboring facility uses DMS as a precursor to another compound for production of medical patches. Seeing this as a mutual beneficial opportunity, our Process team leveraged their experience with H₂S to create a new process by regressing coefficients in the simulation model based on lab work to predict the reaction chemistry.

Once the process was designed, our full discipline team took the concept to reality. We were able to successfully integrate a grass roots plant including five (5) fractionation towers and several supporting pieces of equipment into the existing facility. Our team helped with providing operator training and assisting with start-up, commissioning, and construction support. At the completion of the project, the DMS produced was of higher quality than the chromatograph calibration sample!

This project was so successful that we are now looking into opportunities to expand production capacity by either modifying the existing plant or installing a parallel plant.

C&I provided a complete process design package for a Hydrogen Sulfide Plant to support nickel mining operation. By establishing the turnaround and design parameters upfront, our team was able to complete the system design quickly and efficiently. Our team was on-site for 8 weeks performing operator training and assisting with start-up and commission. We worked alongside a multi-cultural team to ensure a smooth install and start-up.
