Campofrio Alimentacion S.A. is a leading international
company within the food sector. It produces meat products
which require significant amount of heat in the form of
steam and hot water including industrial cooling and electrical
energy.
With the purpose of reducing energy costs on the production
process and equipping the company with flexible installations
in order to meet both present and future energy needs in
a secure and efficient manner, Guascor Energia entered in
a joint venture with Campofrio in order to build a trigeneration
plant producing heat, cold and electrical energy.
The Trigeneration plant operates 24/7 with a total of 8,700
hours annually.
The installation incorporates four turbo charged gas engines
each one rated at 3MW with a total installed power of 12
MW.
To cover the cold demand on the production process, the
trigeneration plant is fitted with an ammonia-water absorption
machine, which runs off saturated steam obtained from the
heat recovered from the engines exhaust gases.
OXAQUIM is a leading business in the manufacture of oxalic
acid, which for its production process needs significant
amounts of steam, industrial cooling and electricity.
Guascor Energia, after having carried out a meticulous
program of measurements for the process’s thermal
and electrical needs, decided to install a trigeneration
plant, the goal was to reduce the plants energy costs and
to improve its performance.
The plant was built under a joint venture scheme with Qxaquim
and the electric company ERX. It operates 24 hours a day
365 days per year. The plant has 10 Guascor FGLD 480 gas
engines with a total installed power of 6.6 MW.
Control System
The plants control system is based on microprocessors allowing
for a centralized supervision and ease of operations. The
system can produce reports to assist with its management
and to optimize the plants performance.
Electrical Energy
The electrical energy is generated by 10 generators each
rated at 800 KVA at a voltage of 660V. The generators operate
in parallel with the electric company’s grid to which
they export any non consumed electricity.
Thermal Energy
The steam needed for the process is supplied by two heat
recovery boilers running off the engines’ exhaust
gases, producing 2,600 kg of saturated steam per hour at
a pressure of 8 bar.
Hot and Cold Water
70 degree Celsius water is needed in the manufacturing process.
This is obtained by using a heat exchanger in the engines’
cooling circuit.
On the other hand, part of this heating power is used to
generate cold water at 7 degrees, by means of a lithium
bromide absorption chiller. This is done with hardly any
consumption of electricity.
