Chemical companies are clamoring to proclaim their energy efficiency success and I got several emails asking why they were left out from my ICIS Chemical Business' August 17 article "Optimizing Energy - Chemical firms lower energy use with new technologies."
Since the blog has unlimited space (I think) and that article only has 2 pages to fit, here are several other energy efficiency initiatives from chemical companies within the past year:
The company said it was able to reduce energy use and carbon dioxide emissions at its Blue Island, IL, production facility simply by "challenging assumptions about standard industrial practices," according to Operations and Maintenance Manager Nathan Mills.
The facility's natural gas consumption was reduced by 40% over the past 2 years, and some production batches are run with up to 30% less heat. Additional energy savings came from recovering the heat naturally generated by production and using it in place of conventional heating methods during winter months.
Rhodia plans to launch several more energy efficiency projects in the near future.
Bayer says its IMPACT technology for polyether production processes dramatically improved the company's Channelview, Texas, plant by reducing 80% in energy consumption and eliminating 75m lbs/year of wastewater.
The company says the technology is being considered for implementation worldwide as plants are being upgraded or constructed. The key to the new process, according to Bayer, is a combination of a catalyst invention and the design of a novel process where low molecular weight materials react preferentially in a mixture of molecular weights.
ExxonMobil installed in March its newest high efficiency cogeneration
plant at its Antwerp, Belgium, refinery, and says that it has invested
in over 1,500 megawatts (MW) of cogeneration capacity in five countries
Cogeneration is the simultaneous production of electricity and
useful heat or steam used for industrial processes. This results in
lower operating costs and significantly less greenhouse gas emissions.
Antwerp's new cogeneration plant is capable of generating more than
125 megawatts of electricity. ExxonMobil says additional new facilities
are under construction in Singapore and China and will increase the
company's cogeneration capacity to more than 5,000 megawatts in the
next three years.
ExxonMobil Chemical is one of this year's 17 Responsible Care Energy
Efficiency Award winners given in May by the American Chemistry Council
The company has received 11 Energy Efficiency awards this year from the
ACC. Some of their manufacturing improvements included unique use of
raw material stream to reduce energy demand, and conversion of boilers
from superheated to saturated steam.
