Switchboards for "Bio-renewable"

Cierre attended with a group of companies in the design and manufacture an innovative pilot plant aimed at dicomposti treating ligno-cellulosic biomass, to obtain biofuels through experimental and patented technologies in the renewable.

The project, which lasted more than eight months at the turn of 2012 and 2013, involved a group of Italian companies with specific skills, coordinatesi to provide process consulting and engineering capabilities useful to provide a key high-tech plant in hand, fully automatic, controllable Internet, earthquake-proof.

.

Companies that have contributed to the project have been the first such prime contractor for the design and construction plant, a second for the study of the process, in addition to CIERRE for the implementation of the power-electronics.
Was responsible for the implementation of the management section and Electric plant control, CIERRE provided the electrical panels, the wiring board machine, and the main components used including PLC and ABB drive inverters, sensors Blue Sensor and Krohne and Enress + Auser, Sartorius and Dini Argeo, temperature sensors - pressure - flow, CO2 and O2 analyzers.

The plant is essentially composed of 3 tanks of 150 Lt, 1500 Lt, 3000 Lt, for the treatment in sequence of the various compounds. Two tanks (150 liters and 1500Lt) are operated on load cells for the verification of weights during the process.

The painting, wiring and connections were made using components appropriate to ensure a degree of protection IP54, protected also by vapor spills, oils, ammonia.


All the paintings were made of stainless steel AISI 304.
The operating temperature of the plant is in the range from -20 ° C to + 150 ° C.

The Quadristica is equipped with UPS continuity group for the maintenance of the control in case of power mains failure.

The plant is equipped with security systems for detecting and dieventuali managing emergencies in the field.

Plc ABB MP573 series operates the plant automatically or manually, by keeping track of process LOG via a PC in Ethernet.
