Line drainage system and water supply/sewerage/sanitary connections were constructed, and washers and separators were installed at PKN ORLEN distribution facilities (at newly constructed facilities in new locations or at existing purchased/leased facilities being adapted to the Company’s standards). At PKN ORLEN’s fuel terminals, wastewater treatment systems were upgraded and vapour recovery systems were installed for handling operations.
PKN ORLEN expanded its leak detection and repair (LDAR) system to cover more production units, this time in the petrochemical section of the Płock and Włocławek production plants. Hence, the relevant requirements of Best Available Techniques were fully met in a timely manner. The purpose of the project is to identify, monitor and reduce diffuse emissions of volatile organic compounds, thereby contributing to the reduction of the plant’s environmental impact and feedstock and product losses, as well as to improving the process safety and staff’s working conditions. Roughly 170,000 potential emission points were examined at 16 production units as part of the implementation activities in the petrochemical section of the Płock and Włocławek production plants. Importantly, the examination showed a very low leak rate of less than 1% at the petrochemical units.
A number of investment projects were carried out in ORLEN Lietuva process units where high-pressure steam was replaced with low-pressure steam, thus reducing the consumption of gas fuel. Upgrade of the heat exchangers and sealing of the heaters enabled reuse of heat for heating lower temperature streams. The projects have helped to optimise fuel and energy consumption for the production of process steam.
ORLEN Unipetrol completed the construction of a new boiler house at the steam cracking unit, which now meets the BAT emission requirements for LVOC units. The company also carried out a number of projects concerning wastewater management, which included: replacement of the industrial sewage pipeline, installation of equipment for collection and transport of sludge at the wastewater treatment plant, commissioning of new pumping stations, and commencement of construction of an emergency sulfur drain and overflow tank.
A state-of-the-art flue gas desulphurisation unit was constructed at Energa Elektrownie Ostrołęka, significantly reducing SO2 and dust emissions. At Kalisz CHP Plant, a peak-load/reserve water gas-fired boiler house was constructed, with two 20 MWt boilers and one 10 MWt boiler.
Installation of a heat pump along with solar photovoltaic system and adjustment of the central heating system was completed in the ORLEN KolTrans administration building in Włocławek.
