■ Carbon Capture Technology
● Technology Overview
▶ Establish carbon capture technology by chemical absorption with formulated high-efficient
absorbent and optimized operation parameters with computer modeling allowing energy
consumption to be less than 3GJ/tCO2.
▶ The desorbed high purity CO2(>99.9%)can be utilized in the production of dry ice, electronic grade
CO2 as well as low carbon chemicals such as methane, methanol and dimethyl carbonate.
▶ The flue gas pretreatment has utilized a unique absorbent to remove the H2S and reduce the SO2
concentration below 1ppm.
● Implemented Fields
▶ Coal-fired power plant/boiler.
▶ Petroleum/cogeneration plant.
▶ Steel mill.
■ Highly Effective Automatic Microreactor System
● Technology Overview
▶ Be beneficial for high-speed mixing and high heat transfer performance, narrowed distribution for
reactants’residence time, repeatability, and quick process response than the traditional batch
reactor.
▶ An easy-operate unit that rarely has the scaling-up effect and with fewer residues remaining.
● Features
▶ The designed novel micro channel reaction apparatus makes the reaction rate 3 to 8 times the
origin(US10537869B1, TW202023679A)
▶ An application on continuous extraction is operated near the thermodynamic limit
(TW202228831A, US patent pending)
● Applications
▶ In Tadalafil synthesis, the reaction time had been shortened to 60 times, and byproduct had
reduced by around three times.
▶ In p-toluene-sulfon-amide(PTSA)synthesis, the yield had been enhanced by around 10~15%.
▶ The product purity is greater than 98% in manufacturing the active pharmaceutical ingredients of
triglyceride-lowering medicine.
▶ Optical-activity medicine synthesizing. The conversion is raised from 20.5 to 80.6%;purity is
increased from 56.1 to 76.6%.
▶ Shortcut the hydrogenation reaction time to 7 minutes(4 hours for origin)
■ Acid-Base Washing and Dust Removal via HiGee Technology
● Technology Overview
▶ A technology with a more extensive interfacial area that results in water-soluble contents could
be rapidly and effectively removed.
▶ Allows liquid to be repeatedly used with an automatic adjustment function on absorbent.
● Features
▶ Simultaneously pull out particles, water-soluble organics, and acid(or base)compounds.
▶ No risk of being stuck by particles!
▶ Lower occupied space to 50% than others(e.g., wet dust collector)
▶ High flexibility in operation, reusable absorbent, and high removal efficiency under low pollution feed.
▶ Removals of PM2.5 and PM10 are greater than 95% and close to 100%, respectively.
■ Thinner Reclaim System of LCD Panel Plant
● Background
▶ A massive amount of waste solvents(about 20K ton/yr in Taiwan)has been generated in LCD panel
processes; the recovery & purification of the thinner from those wastes are difficult due to photoresist
and multi-component.
▶ Besides, the outsourced treatment charges a higher fee and usually gets poorer recovery quality
▶ Existing TRS with a low recovery rate that leads to the recovered thinner could only be downgraded
applications.
● Implementation of ITRI-MCL's Technology
● A Commercial Case
▶ ITRI’s patented high-efficiency DWC(Dividing-Wall Column)distillation technology, energy-saving
equipment with lower hardware investment and less land occupied, was applied.
▶ The distillation facility has been operated since 2021; the annual recycled amount is 6500 tons. The
recovery rate has increased from 45% to 90%.
▶ The recovered quality is better than the electronic grade and is again utilized in the panel-making
process.
▶ The by-product containing multi-solvents is sold for other industrial applications.
