HISAKA PHE in Bioethanol Plants - A Leading Solution in Preventing Global Warming by Reducing Emission of CO2 in Fuel Combustion

High Efficiency HISAKA PHE in Bioethanol Plants –A Leading Solution in Preventing Global Warming

Approaches to CO2 reduction has been a great industrial focus since the enforcement of Kyoto protocol due to acceleration of global warming. With the surging of petrol prices, environmental friendly bioethanol fuel is renowned as an alternative to gasoline, reason adopted from photosynthesis whereby consumption of oxygen in fuel combustion will not accelerates atmospheric CO2 levels. Japanese government aimed to reduce 80% of dependencies on petroleum in the transportation sector by year 2030,beginning with effort such as blending 3% bioethanol with gasoline as fuel. One limitation to this vision is lack of supply
source wherein ethanol has to be derived from cellulose derivatives found in wood waste, weeds and timber from deforestation. Consequently, focus has been placed on developing crops with high bioethanol yield.
To efficiently increase product yield, the heat exchangers used throughout the processes require excellent heat transfer performance. HISAKA PHE delivers various advantages, especially its outstanding heat transfer performance, leading to great innovation in plant engineering.

PHE facilitates higherefficiency of fermentation and distillation process

Bioethanol is a global trend, especially with cellulose. With economical constrains, industries emphasize on reducing the production cost of ethanol, a factor determined by the efficiencies of converting both cellulose and hemicellulose (approximately 60% of wood materials) into ethanol. Wood saccharification with diluted sulfurous acid requires PHE made of corrosion resistant materials along with wide-gap plates to reduce slurries clogging from the degradation of hemicellulose and other substances. It is also crucial to ensure that the ethanol is produced from sugar generated from saccharification process, with the elimination of fermentation heat and act as preheater during pre-fermentation process. Multi-stage distillation is used to condense the produced ethanol for commercialization. This process requires high performance condenser type PHE (HISAKA YX-Series) which emphasizes on small temperature difference and high condensing capacities. As such, HISAKA is able to cater for various industrial needs and conditions with its wide product pipelines.
