Nanjing Invelychem has developed a defoamer (anti-foaming
agent); Invely-0030, which exhibits a superior defoaming property in the
sugarcane ethanol production process.
【Background of the
development】
Amid the taking
measures against global warming, bioethanol is considered a green alternative
to gasoline that does not affect the total amount of CO2 in the
atmosphere. It is expected to be carbon-neutral biofuel and its use has been
steadily increasing mainly in U.S. and Brazil.
Bioethanol is
produced from feedstock crops such as sugarcanes and corns via alcoholic
fermentation. Especially sugarcanes give very high bioethanol yield per unit of
land; thus bioethanol has been already widely used in Brazil where the largest
amount of sugarcane is produced worldwide.
Bioethanol is
produced by a decomposition of sugar to ethanol and carbon dioxide through
alcoholic fermentation using yeast. Carbon dioxide generated during the
fermentation process creates a lot of foams, and the foams cause troubles such
as an overflow of the fermentation tank and a pump failure by an air locking.
Defoamer plays a crucial role to eliminate such troubles.
Besides,
suppressing foams can minimize the dead volume occupied by the foam in the
tank, and accordingly increase the productivity of the ethanol.
However, since it is a biological process,
foam formation is affected by multiple factors such as temperature, medium
composition including impurities (their amount and types) and condition of
yeast. Therefore, it was difficult to develop the defoamer to perform
effectively regardless such factors.
Nanjing Invelychem
has been developing various defoamers and leading the industry since our
establishment in 2005 by leveraging our abundant field experiences and surfactant
technologies. We have also developed a lot of original evaluation methods
capable of reproducing complex field conditions in the lab. Based on such
accumulated expertise, we have developed the defoamer; Invely-0030, which is
effective for the sugarcane ethanol production process.
【Features of the technology】
Invelychem-0030 is
a surfactant having excellent water-dispersibility and has features below.
1.
Excellent defoamability - Eliminates the troubles caused by foams -
Increases the productivity by utilizing the dead volume occupied by foams -
Reduces the amount of use compared with conventional defoamer
2.
Widely applicable to meet the diverse fermentation conditions (temperature,
media composition and yeast)
3.
Not inhibit the ethanol fermentation These features
are highly evaluated and Invely-0030 is increasingly being used in Pakistan
which is the largest producer of sugarcane ethanol.
【Feature Plan】
The utilization of bioethanol is expected to
proceed further as a leading measure against global warming. Nanjing Invelychem
will promote further sales of Invely-0030 to major sugarcane ethanol producing
countries not only Pakistan but other countries such as India, Thailand and
Brazil. Nanjing Invelychem will provide detailed supports globally to the
various problems with prompt and proper solutions. And we will contribute to
respond quickly to the changes in the times and customer needs, and reduce the
environmental load by putting priority on “Environment and Energy”.
