Compablocs ensure process stability in major Czech petrochemical company

Unipetrol is the Czech Republic’s leading refinery and petrochemical group. In 2007, at Litvínov, 13 Alfa Laval Compabloc heat exchangers in stainless steel were chosen by engineering and supply company Intecha Ltd. for a new benzene production unit. According to Intecha, the Compablocs ensure stable operation all year round, irrespective of changes in the temperature of the cooling water.

Michal Drebitka, Chief Technologist, Intecha Ltd., explains that initially traditional shell-and-tube heat exchangers were selected for the project:

However, we decided to compare them with plate-type heat exchangers as we have had positive experience with this technology in the past. The main focus at the time was on making a price comparison.

Miroslav Malecký, Unipetrol Litvínov’s Production Manager, relates that his company appreciates the efficiency and reliability of the Compablocs:

Their compact size is also beneficial in this application. The new benzene production unit, based on extraction technology, had to be placed inside a steam cracker in a very limited space. Compared to shell-and-tubes, the Compablocs occupy less space, they are easier to clean and they require less room for cleaning.
