Project Description

Butadiene production plant situated on the petrochemical complex of Braskem. The unit produces 103.000 Tons/year.

Emasa Engineering designed studies for the erection engineering and rigging plans of the 6 towers needed for the process that had been split for transportation with total heights of about 85m and in several different shapes.

Lifting lugs and trunnions were analyzed, reinforced and designed through very refined methods of finite element due to worries with localized loading effects on the shell of the towers. Studies were also performed to allow the union of towers sections on the ground prior to the verticalization and rigging in order to speed up schedule and reduce costs.

Emasa Engineering also developed procedures and structural verifications for steel structure assembly optimization, including modularization and rotation studies.
