“Ethylene XXI” Production Plant, Coatzacoalcos, Veracruz, Mexico

The biggest ethylene production plant in all of Latin America
ULMA played a critical role in this project, which is the biggest ethylene production plant in all of Latin America.

Description

A petrochemical plant was completed in Coatzacoalcos, Mexico, to meet the domestic demand for petrochemical products, substituting imports with highly competitive national production.  An estimated 40% of polyethylene products currently imported will be supplanted by these facilities alone.

ULMA played a critical role in this project, which is the biggest ethylene production plant in all of Latin America.

We consider it extremely important to offer simple, rapid, and effective engineering solutions for projects such as these, which greatly affect the economy of the host country.

ULMA solution

The structures built for this project are composed of columns with a cross-section of 1 m x 0.6 m and slabs at heights of 7.48 m and 10.48 m respectively.

To construct the columns, lightweight NEVI formwork was used in structures reaching 7.5 m tall composed of panels 2.4 m and 1.2 m tall, with widths of 0.75 m, 0.4 m, and 0.3 m. As a special feature, pouring windows were set in the columns at a height of 3.5 m.

BRIO shoring was used to support the slab surface measuring 1,400m2 with a thickness of 0.3 m in some sections, and up to 1.2 m in the beam sections. Shoring towers with cross sections of 2.5 m x 1.5 m and 2.5 m x 1.02 m met the high load-bearing requirements. BTM beams made the primary formwork structure, with VM-20 beams used as joists. 

NEVI formwork was used for the walls, while large multidirectional BRIO scaffolding structures were used for the work at height.
