ORLEN Unipetrol, the largest refining and petrochemical group in the Czech Republic, continues modernising its chemical facility in Záluží near Litvínov. To gradually meet the targets within its low-emission strategy, the company replaced the current boiler plant for the steam cracker’s operations with a brand-new gas boiler plant. The total investment reached CZK 1.2 billion. The state-of-the-art equipment has contributed to lowering the dust emissions by 50 per cent and NOx emissions by 70 per cent.
“We continue developing our production capacities to increase efficiency and lower the energy and emissions intensity. The brand-new high-tech boiler plant of the steam cracker is a great example. Its commissioning is another step towards carbon neutrality, which we aim to achieve by 2050 at the latest,” says Tomasz Wiatrak, Chairman of the Board of Directors of the ORLEN Unipetrol Group.
The new steam cracker boiler plant contains two high-pressure oil-and-gas boilers. Each can generate up to 105 tonnes of high-pressure steam per hour (at the temperature of 520 oC and pressure of 11.5 MPa). Their efficiency is by about three per cent higher than the current heat source. The latest equipment for emission reduction has helped decrease the dust emissions by 50 per cent and NOx emissions by 70 per cent. ORLEN Unipetrol currently meets the requirements set out by Czech and EU air-protection legislation, including the stricter emissions limits based on the EU document entitled Best Available Techniques Conclusions for Large Combustion Plants, which became effective in August 2021.
BERTSCHenergy from Bludenz, Austria, was responsible for the turnkey project implementation. As a general contractor, the company offers customised power plant solutions for industrial enterprises and regional energy suppliers, focusing on maximum efficiency in terms of performance and costs.
