p Bioethanol as a replacement for conventional fuel
Clever Alternative
Siemens offers a perfectly balanced portfolio that
covers all areas of the ethanol industry based on Totally
Integrated Automation.
Growing energy demand and spiraling oil
prices are putting financial strain on countries
and causing increased demand for fossil
fuel. Energy security has assumed greater significance
than ever as energy consumption, food
production and environmental quality are interconnected.
As a result, many countries throughout the
world see an attractive alternative in ethanol.
A large number of measuring tasks have to be carried
out in a manufacturing plant for bioethanol –
starting with the receipt of raw materials and up to
the delivery of the finished product. Selection of the
correct instrumentation is very important for the efficiency
of the complete plant. In addition to the technical
specifications, the instruments must be safely
integrated into the process automation. Reliability,
long service life, and simple operation are also important.
And in an emergency, a fast and trouble-free
supply of spare parts must be guaranteed.
Million liters) of ethanol. Corn is used as the primary
feedstock. The project was realization from
January 2003 to September 2003 with Siemens
China “SIAS”, Shanghai provided the project management
services. The system was implemented
by Vogelbusch as the contractor.
The unique combination of TIA used throughout
the plant includes the distributed control system
Simatic PCS 7, a highly distributed 8000 I/O system
with HART, PDM and optical network, eight redundant
controllers, nine Operator Stations implemented with
Chinese characters, and an MES based on OPC.
Siemens, a partner for bioethanol
Siemens has recognized the challenge and offers a
perfectly balanced portfolio that covers all areas of the
ethanol industry. Using Totally Integrated Automation
(TIA) - all encompassing of a unique vast of products
and systems portfolio, Siemens provides solutions for
the complete ethanol process from receiving of raw
materials to storage of the finished product.
Jilin Fuel Ethanol plant in China
Following a first boom in Brazil in the seventies, the
tremendous increase in the price of petroleum and
the recent demand for energy has finally turned ethanol
into a global issue. In the USA alone, more than
30 installations are being built every year and similar
figures are being constructed in Brazil. In Europe, a
traditional stronghold for biodiesel, planning is underway
for a large number of ethanol plants. In Southeast
Asia, the first installations have already commenced
operations, including the largest plant in the
world, located in Jilin, China.
The largest ethanol plant in the world, Jilin Fuel
Ethanol Co Ltd in China, was implemented with
Siemens distributed control system PCS7. The current
capacity is 200 Million gallon per year (750
Optimizing the complete workflow with
Totally Integrated Automation
Siemens is the only single vendor that can provide a
complete line of products and automation systems
throughout an ethanol plant including all auxiliary
systems. One set of engineering tools provides process
automation from the field level to the control
level through the enterprise management level including
superior system diagnostics and asset management
functionality. Reduced life cycle costs,
shortened times to market and improved production
efficiency can be easily achieved.
Besides greater independence from fuel oil, which
is becoming increasingly expensive, there are further
arguments that speak clearly in favor of ethanol, namely
reduction of greenhouse gases taking into consideration
the entire CO2 cycle and reduction of toxic
emissions when burning sulfur-free ethanol. Biofuels
are also less toxic than conventional ones. p
