We have taken a number of steps at our production facilities over the past few years to improve energy consumption efficiency and to mitigate or reduce eventual energy losses.
MOL Group is committed to reducing its environmental footprint. We have recognized the importance of increasing energy efficiency - thus we have taken a number of steps at our production facilities over the past few years to improve the efficiency of energy consumption and mitigate or reduce eventual energy losses.
We annually report on our energy consumption in the Annual Report – click here to read the 2009, 2010, 2011, 2012, 2013 summary.
Below is an overview of the measures implemented in recent years in our business divisions:
Exploration and Production:
- Preparing studies to rationalize electricity consumption rates at four sites;
- Launching an energy rationalization project (“ENRAC”) aiming at long-term energy and cost savings; improving the efficiency of long-term oil and gas producing operations and at the same time decreasing of our environmental footprint;
- Replacing gas engine driven compressors with electric ones, with the effect of decreasing CO2 and noise emissions and decreasing maintenance needs - resulting also in the generation of less hazardous waste;
- Modernising steam heating systems in our gas technology units through replacing them with water heating types.
Refining and Marketing:
- Revamping distillation columns in the gas fractionating unit (Duna Refinery);
- Reducing pressure on the industrial water system (Duna Refinery);
- Optimizing APC with the installation of temperature meters in GFR unit (Duna Refinery);
- Decreasing LP steam-consumption of the E-102 air cooler during coke fracturing. (Duna Refinery);
- Shutting-down of the de-propanizer and stripper processes in our HF Alkylation unit (Duna Refinery);
- Saving condensed water to stop it “running to waste” (Duna Refinery);
- Decreasing nitrogen consumption in the Maleic Acid Anhydride production unit (MAA unit) (Duna Refinery);
- Using of thermostatic electric heating instead of steam heating at places of freeze risk (Duna Refinery);
- Revising and reconstructing pipeline-heating (Tisza Refinery, Zala Refinery);
- Minimizing heat loss at refinery production unit steam traps (Slovnaft Refinery);
- Reviewing the impact of decreasing pressure in the process circuit at the ETOX production unit (Slovnaft Refinery);
- Effectively utilizing the cooling capacity of water at once-through cooling systems (Slovnaft Refinery);
- Decreasing raw water consumption by replacing once-through cooling water with circulation cooling water at Slovnaft Refinery production units;
- Optimizing medium’s temperature at Slovnaft Refinery production units;
- Modernizing heat-storage heaters in office and technological building units, replacing the steam-heating systems of 2 product lines with electric heating (Logistics HU);
- Modernising vapour recovery units (Logistics HU);
- Terminating reserve electric power supply at Csepel Base Depot, and at the same time installing a gas engine driven generator (Logistics HU);
- Decommissioning the old boiler shed at Csepel Base Depot and commissioning a new heating system with a stand-alone gas boiler (Logistics HU);
- Reconstructing locomotives T448 (Logistics SK);
- Replacement of outdated pumps with new energy efficient units at bottom loading filling stations and at the barge unloading facility at Korneuburg (Logistics A).
- Utilizing the outgoing fuel gas waste heat in the heating hot water system at the Power Station (the quantity of steam required for TVK operations is still ensured by TVK Power Station which ensures low CO2 emissions and profitable production);
- Removing a low-utilization line at the old Plastics Processing Plant (TVK);
- Decreasing steam consumption in SC2 through reconstruction of the 110/24 bar steam reducer (TVK);
- Replacing road and plant lighting lamps with low consumption compact tubes (TVK);
- Reducing the number of product change stops at HD2 (through a change between 7100S and 6300B product types) (TVK);
- Reducing high pressure steam consumption through maximizing the use of the condensing water at SC (SPC);
- Reducing steam network losses by replacing DN 500 line supplying steam for PP logistics with a new low diameter (DN80) direct line (SPC);
- Utilising ADT (Advanced Donor Technology) instead of CDT (Conventional Donor Technology) in the PP3 plant (SPC).
- Preparing an energy balance and usage study for filling stations;
- To promote the everyday use of energy saving solutions, the RVI standard (Retail Visual Identity) has been upgraded with economic LED lighting on filling station roofs;
- LED lighting and energy efficient light bulbs were installed in the SHOP and forecourt area at 2 filling stations in Budapest in a pilot project.
- The ’Fuel Station of the Future’ project with environmentally responsible and energy efficient soultions
Supply an Trading (former Gas- and Power):
- Launching of an Energy Audit in TVK factories by the Energy Efficiency Team to examine the energy supply system (as a first step) and preparing of audit structures within MOL Group for the next phase;
- Launching a pilot project of 0.25 MWe generation capacity (using Organic Rankine Cycle (ORC) technology) in order to prove the technical feasibility of such applications before broader scale implementation.
