A long period of time was dedicated to the process of selecting companies with experience in the field, along with the identification of the best and safest technologies for neutralizing and eliminating these acidic tars, generated over time by the technological processes for obtaining fuels and crude oil processing.
The actual stage of the project implies two main trends: treating tars and transforming them into solid waste that will be stored on site without endangering health and environment, as well as recovery through co-incineration in authorized plants (cement factories)
A major benchmark for the choice of the technological solution was its sustainability, with the company planning to monitor the area and water sources for 30 years after the completion of the works.
The treatment of these tars implies solutions adapted to their stabilization and neutralization. For stabilization, internationally certified professional binders, such as those used in civil engineering and those used to stabilize soils in motorway construction, will be used.
Enviromental protection and care for communities
To protect the local communities near the refinery and to reduce the impact of these works, the refinery developed and implemented a comprehensive program of measures:
Creation of a green curtain around the historical lagoons
Constant monitoring of the groundwater through more than 20 drillings
Installation of air monitoring stations
Installation of soundproofing panels for noise reduction
Industrial exhausters / “suction apparatuses” for retaining gas and dust, dusting stations, the use of water curtains for particle retention.
Operations will be monitored by constant measurements of environmental parameters and by perimeter measurements to comply with the maximum noise limits permitted by law.
In addition, the refinery will mount in the next period an electronic display panel at its perimeter boundary, which will provide real-time environmental data to those interested.
Strict cleaning and safety measures
The transport of the waste will be carried out in a dedicated refinery area, with trucks that will be covered with a tarpaulin. Wheels of every truck will also be cleaned to avoid soiling the asphalt.Stabilizing materials will be transported in tightly sealed cement trucks, these means of transport respecting all the statutory requirements.
The traffic of the trucks loaded with neutralized waste for recovery shall be carried out only with prior notification of the Inspectorate for Emergency Situations and following the route established and approved by the state authorities.
For the supply with the necessary products as well as for evacuation to the authorized points of valorization of the treated tars, a dedicated access path was established to DN1B - Ploiesti belt. The route was chosen and agreed with the local authorities, in order to reduce the impact on residential areas.
In the first phase, daily traffic is estimated at about 5 trucks, which will vary, depending on the volume and necessity of the products / materials. The approved work schedule for settling tanks’ remedial operations is from Monday to Friday, 10 hours a day, with an hour of pause.
