Funded Projects

We are carrying out an energy efficiency improvement project at the Crude-1 Industrial Complex in A Coruña that consists in the installation of two new heat exchangers that recover heat from products to be used to pre-heat crude oil being sent to the furnace, and thus reduce fuel consumption in the unit's furnace. This will lead to a reduction of 5,082 tons of CO2 per year in one of the largest units at the refinery, which could mean an energy savings of 2.2341587 ktoe/year.

This €3,000,000 investment is part of Repsol's 25/25 Plan for emissions reductions. The project has received aid amounting to €1,080,000 from the financial assistance fund for energy efficiency and savings in SMEs and large businesses in the industrial sector, which is co-financed by the European Regional Development Fund (ERDF), coordinated by the Institute for Energy Diversification and Savings (IDAE, in Spanish), administered by the Energy Institute of Galicia (INEGA, in Galician), and paid out of the National Energy Efficiency Fund, with the objective of achieving a cleaner, more sustainable economy.

At the REPSOL PETROLEO industrial complex in A Coruña, a project has been carried out involving a series of modifications in the low pressure section (stripper) of the Unifiner 2 unit aimed at achieving its operational and energy optimization. This project consists in replacing the stripper plates and five control valves, incorporating recirculation for minimum flow in pump P-P4A/B, and installing a variable speed drive for engine P-E4.

These modifications will lead to energy savings of 0.585548 ktep/year, thereby avoiding 1,373.48 tCO2/year of emissions into the atmosphere, which results in direct natural gas and electricity savings for the complex.

Energy losses in the low-pressure steam network and condensate recovery have been reduced by reducing steam pressure from 18 bar to 6 bar and reducing steam consumption in the asphalts area, U714, as well as recovering low-pressure condensate in the Tank area, U724. Thanks to these actions, energy savings of 424.86 toe/year and 994.00 tCO2/year avoided have been achieved.

A new 653-E-XX1 exchanger has been added to heat naphtha by recovering residual heat from kerosene. On the other hand, a new sulfur adsorbent bed 651-C-XX1 has been added to reduce the sulfur content in naphthas, so that this can be fed directly to the 651-C4 stripper. These actions allow energy savings in reaction furnaces 651-F-1 and reboiler 651-F-2, which are part of the naphtha desulfurization unit U-651. Thanks to these actions, energy savings of 1,374.20 toe/year and 4,026.72 tCO2/year avoided have been achieved.
