OREANDA-NEWS. November 26, 2010. A column for the separation of propane-propylene fraction with a height of 96 meters and weight of 1095 tons has been installed in cooperation with experts from the Dutch company Mammoet and the installation company Trest № 7.

"The column is the heart of the propane dehydrogenation plant," said Dmitry Fomin, the director of capital construction at Tobolsk-Polymer.

The lifting of the equipment was carried out using a gantry crane system and two auxiliary cranes. Earlier, transportation trolleys brought the column to the installation area, where it was placed between the two pillars of the portal crane. After the removal of the ties fixing the column to the trolley and slinging with the gantry crane, the lift of the massive equipment began.

According to Alfredo Errico, the engineer from the contractor Tecnimont (Italy), assembling the almost 100-meter column was a unique operation. The Dutch company has carried out such operations in other countries, but the equipment for Tobolsk-Polymer was the heaviest they have had to deal with.

The installation of the column lasted 6 hours. Despite the weather, the operation went ahead without problems.
