New recycling plant for the Repetco company in the Romica industrial estate, in Albacete.
The electrical installation departments are involved in this project; mechanical installations; and the subsidiary Conscytec.
This is a unique and innovative project in which the company has coordinated and executed the civil works; electrical installations; mechanical; control; and asset security.
Civil work
The recycling plant will be made up of six attached warehouses for the different recycling processes; as well as an office building, R&D and auxiliary facilities rooms. It will also have auxiliary facilities, such as an industrial treatment plant (EDARI); a tertiary treatment plant for reuse of the water treated at the WWTP in industrial processes; truck wash, etc.
The structure and envelope of the buildings will be made of precast concrete. They stand out for heights of up to 20 meters and spans of up to 33 meters.
Electrical installations
The electrical connection to the plant will be carried out in Medium Voltage, with an installed power of 8 MVA. The building’s transformation center will have three transformers in a (2+1) configuration of 4 MVA each. These will be connected to a CGBT of 6300A and a breaking capacity of 100 kA. The configuration of the plant protection system will be IT, except in offices and auxiliary service panels. These will have a TN protection system. The different electrical lines that will feed the process panels and auxiliary services will start from the CGBT.
The plant will have a high degree of automation, having a control and supervision center in which the control SCADA will be installed. This will integrate, monitor and manage communications between the different process PLCs; as well as the production management program. To achieve this control, it will be necessary to execute the fiber optic installations and structured cabling necessary for the interconnection of the different points of the system.
Mechanical installations
Mechanical installations include the following works:
PCI installation. The plant will be provided with a network of hydrants, BIEs and sprinklers; as well as fire extinguishers, automatic extinguishing, and fire detection installation.
Gas and steam installation. The facility will have two steam boilers with a production of 4,000 Kg/h each; as well as the gas installation associated with them.
HVAC installation. The facility will have two chillers of 1,200 KW each dedicated to both process equipment and temperature control of the warehouses. The air conditioning of the offices will be carried out by installing a Variable Refrigerant Volume (VRV) system.
Compressed air installation. The plant will be provided with a compressed air network. It will have three compressors, with a production of 1,530 Nm3/h. each.
In addition, a CCTV and intrusion installation will be carried out to guarantee the property security of the plant, allowing the Security Forces to be alerted to any intrusion into the facilities.
