Tobolsk, 30 September 2011. At the Tobolsk-Polymer construction site, four reactors have been installed at the propane dehydrogenation unit. The unit’s assembly took place within the framework of installing large-sized equipment at the site.

As part of this programme, in September 2011, 21 units of oversized and heavy equipment were assembled. By the end of October, 19 more units of oversized and heavy equipment are supposed to be installed. These include tower and heat exchangers, tanks, reactors, and a catalyst regeneration unit. The heaviest unit is the Cold Box refrigeration system unit, weighing 282 tonnes. The most voluminous unit is one of the modules of the catalyst regeneration unit, which is almost 53 metres in length. LIEBHERR cranes, with a lifting capacity of 350 and 750 tonnes, were used to install the equipment.

The equipment for the propane dehydrogenation unit was produced in factories in Korea and EU countries, and delivered to Tobolsk by road, rail, and sea through Archangelsk and St. Petersburg, then via the Northern Sea Route and up the Ob and Irtysh rivers to the industrial port of Tobolsk.

Background information:

The most notable large-scale operation for the delivery and installation of equipment for the Tobolsk-Polymer project involved the transportation and installation of the propane-propylene fraction distillation column, 96 metres in height and weighs 1095 tonnes, which was carried out in September-November 2010. In terms of its complexity and the technical and human resources required for this operation, this project is unique for both the global and Russian petrochemical industry.
