Successful application case of Hangzhou Shenshi Channel Industrialization
Successful application case of HangzhouShenshi Channel Industrialization
In the pastten years, micro-channel reactortechnology has developed rapidly. Through the design of
the channel shape,the channel size has been extended to the millimeter level, and thecharacteristics of the
micro-channel reactor can be maintained to meet theneeds of industrial production, while achieving "size
enlargement"and "number increase enlargement" "Combined, especially suitablefor multi-phase difficult to
mix, strong exothermic, difficult to control fastreaction, and intermediate unstable, flammable and explosive
reactions,suitable for chemical, pharmaceutical, dyes and other fields.

Hangzhou Shenshi began to introducemicro-channel heat exchanger technology in 2010, and cooperated
with well-knowndomestic universities such as Zhejiang University and Tsinghua University. Itis in a leading
position in the development and design of micro-reactionsystems.
Figure 2 micro-channel reactor
Micro-chemicalcontinuous flow reaction system is the first civilian product developed byHangzhou
Shenshi's self-developed micro-level channel structure design andvacuum diffusion welding technology
application innovation. The device realizesthe product characteristics of safety, high mass transfer efficiency,
high heattransfer efficiency, high pressure bearing capacity, high temperatureresistance and high corrosion
The micro-chemical system innovated a new reactorproduction process, improved the original reaction
conditions, optimized thechemical process, and overturned the intermittent production of traditionalreactors.
The reaction mode was realized as a microchannel continuous flowreaction automation control. The industrial
control of the device isincorporated into the DCS remote centralized control system, becoming an
unattended, continuous and intelligent production of the entire productionline. Among them, the Shenshi
Microchemical reaction plate adopts more than tenunique structural designs, which can be superimposed
according to differentreaction conditions.
Inaddition, the micro-reaction system also adopts a modular design, assembling anintegrated micro-
tubular reactor. Differentpermutations and combinations can meet the requirements of different chemical
processes. Miniaturization and mobility of industrial equipment.
Successful industrial application cases
Hangzhou Shenshi Energy Conservation Technology Co., Ltd.and Jiangsu Yangnong Chemical Co., Ltd.
cooperate in the field ofmicrochemicals. Yangnong Chemical is the largest production base of new-type
biomimetic pesticides-pyrethroids in China. Industries such as chloropropane,agricultural and sanitary
pyrethroids have leading market positions and global influence.
Figure 3 Chemical plant
YangnongChemical’s original intermediate production plant with an annual throughput of18,000 tons
covers an area of about 150 square meters and a building area ofabout 300 square meters. The workshop
requires two floors and the total heightof the device is about 15 meters. The intermediate project is changed
toShenshi After the integrated micro-channel reactor, the whole device onlyneeds a 40-foot container to
be fully loaded. The area is only about 28 squaremeters, and the height of the equipment does not exceed 2

The projectused the Hangzhou integrated micro-channel reactor to completely overturn theoriginal
reaction conditions, and the scale-up experiment of the productionscale proved that the production yield of
the product was increased by 6-8%. Inaddition, more than 1 million energy costs were saved each year.
HangzhouShenshi's micro-reaction system has outstanding advantages in energy saving,environmental
protection, efficiency, space, safety, etc., and is anindispensable upgrade replacement product for traditional
chemical heatexchange equipment and reaction equipment.
