Chemieanlagenbau Chemnitz GmbH has successfully finished the construction of a new plant for benzene enrichment for Total Raffinerie Mitteldeutschland GmbH (TRM). For TRM, it was currently the largest completed investment project in Leuna. For CAC, this meant the successful continuation of a long tradition in the realization of plants at the Central German refinery site. Total invested 30 million euros in the new plant.
The lifting and installation of the partition wall column in March 2017 was one of the milestones of construction. This column with a height of 65 meters and a weight of 245 tons is the core piece of the new plant. Just one week later followed the installation of the assembly unit, which has a weight of 35 tons and consists of four air coolers. Contrary to what had originally been planned in the basic engineering, the complete assembly of the partition wall column was carried out on the basis of pre-dressing. This means: The column was delivered to the construction site in three pieces with a length of 20 meters each. Then it was welded on site in horizontal position. Next, all attachments - fixed ladders and operating platforms, insulation, piping including insulation as well as cable trays were mounted to the horizontal column. Finally, the column was erected and set up in one piece.
During the project phase, all site employees, including CAC colleagues, worked approx. 134,000 hours - this corresponds to more than 15 years of life. They moved 7500 m³ of earth mass, installed 147 t of steel and 558 m of railing.
In the course of plant construction, CAC was responsible for detail engineering, procurement services, expediting and inspection, site management, participation in pre-commissioning, commissioning and performance test run.
