EPC for Chemical Plant

Manufacturing and assembly of the largest stainless steel chimney in Latin America.

In this project, executed in approximately 11 months, MCM carried out the replacement of Paranapanema's Emergency Chimney. In parallel, we also handled challenges such as the dismantling of tower T-1106, relocation of the new Remote House, revamp of the Flash Furnace Cooling Piping and replacement of duct P-1102, all executed during the scheduled plant shutdown in approximately 30 days.

The emergency chimney CH 5201 is the largest stainless steel chimney in Latin America, with 108 meters in length, equivalent to a 36-story building. The engineering was entirely designed using a tubular structure, offering less wind resistance at great heights and optimizing the final project weight.

Its entire structure was manufactured at MCM Metal Mechanics. Over 90 days, our team worked in 2 shifts to deliver the 10 modules and 9 structures on time. The entire chimney was pre-assembled at our Escada Operations Center for testing and adjustments, avoiding setbacks during on-site replacement.

For assembly, 100 days were required, using several large-scale pieces of equipment. We relied on the Innovation and Technology Department to develop an access platform that facilitated the cutting process for dismantling the old chimney, avoiding scaffolding and minimizing time and, especially, operational accident risks.

During the dismantling of tower T-1106 and relocation of the new Remote House, we worked in an aggressive acidic area, yet managed to execute the activities with quality and without any accidents.

The revamp of the flash furnace cooling piping was one of the main shutdown projects, as the plant's return to operation and the production increase expected by the client depended on it, in addition to the replacement of duct P-1102, where part of the spools, structures and equipment used were manufactured by Metal Mechanics.
