defoamer for sugarcane ethanol prodcution process


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”.

The magical effect of fumed silica in silicone rubber

The magical effect of fumed silica in silicone rubber Fumed silica is one of the most important high-tech ultra-fine inorganic new materials. Due to its small particle size, it has a large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion performance, thermal resistance, It has specific properties in terms of electrical resistance, etc. Its superior stability, reinforcement, thickening and thixotropic properties are unique in many disciplines and fields and have an irreplaceable role. Today, Xiaobian will work with you to learn how to apply fumed silica in silicone rubber. Application of fumed silica in high temperature vulcanization (HTV) silicone rubber The use of fumed silica can be divided into silicone materials and other fields, in which the amount of silica in the silicone material is nearly 60%, and the silicone rubber is the most used material in the silicone material. It can be added in an amount of up to 50% ...

How do we assess antifoam efficiency ?

How do we assess antifoam efficiency ? Quality of an antifoam is given by two main characteristics : • Knockdown ability or shock effect :Meaning the speed to destroy an existing foam. • Persistence or durability : Meaning the efficiency over time.   These two parameters can be assessed by several tests. The main test is the bubbling method. A graduated column with a glass frit in the bottom is required. Foaming water is poured in the column and air at constant flowrate is introduced through the glass frit in the column. Foam is generated by the air and starts to travel up the column. At a determined level of foam, antifoam is injected. By this method several antifoaming agents can be tested. A graph reporting foam height vs time is very helpful to establish the knockdown ability and the persistence for each product. The selected antifoam is the product with the best compromise between shock effect and durability       Environmental performance   Silicone antifo...

Why is there foam in the paint and coating? What we should do to eliminate foam?

Why is there foam in the paint and coating? What we should do to eliminate foam?             check below details:           Surface tension The surface tension of the coating has a great influence on the defoaming agent.  The surface tension of the defoaming agent must be lower than the surface tension of the coating. Otherwise, there is no defoaming and foam suppression. The surface tension of the coating is a variable factor, so a constant surface tension is required when using the defoamer, and then the surface tension variation factor is taken into account. The influence of other additives Surfactants used in coatings are mostly functionally incompatible with defoamers. In particular, emulsifiers, wetting and dispersing agents, leveling agents, thickeners, etc., have an effect on the effect of the antifoaming agent. Therefore, we must pay attention to ...
