Automation solution according to IEC standard

Automation concepts for biodiesel plants are designed in Europe in accordance with IEC standards. Our models comprise our SIMATIC PCS 7 process control system, drive and field technology, as well as components for energy management. The production of biodiesel is controlled by means of two single-user operator stations. Engineering is carried out centrally using a uniform GUI, and communication with the operation and monitoring level over Industrial Ethernet.

Distributed control for biodiesel production

The low-voltage power distribution and the automation functions are designed on a distributed basis, corresponding to the plant subsections, of which there are three in our example solution. Controllers from the AS400 series can be used, redundantly if required. Cooling, steam generation or wastewater treatment are controlled locally using SIMATIC S7-300 PLCs or centrally using the SIMATIC PCS 7 control system, frequently also with fail-safe controls. The remote I/O SIMATIC ET 200M/S/iSP can also be distributed between the subsections of the plant. This shortens the cable paths to the field devices, thus reducing the installation costs and commissioning time.

Power distribution and energy management

Motor control center and low-voltage power distribution are combined in the SIVACON switchgear. One switchboard is installed in each of the three switchrooms, comprising the central infeed and motor connection. The large motors of the compression/refrigeration plants are powered directly from the air-insulated NXAIR M medium-voltage switchgear. These are also integrated via PROFIBUS DP into the automation system.

As you can see, Siemens offers solutions tailored to your requirements for biodiesel production. The integrated automation results in increased efficiency and profitability of your biodiesel plant.
