Recently, Juhua Group Corporation completed the acceptance test of SUPCON Advanced Process Control solution (APC)
adopted in the R142b and 701(AHF) Units. In 2018, SUPCON signed 1.5million USD
contract with Juhua over their engineering plastic intelligent manufacturing
The R142b unit covered six units,
including reaction system, hydrogen chloride recovery system, water alkali
washing system, R143a distillation system, R143a recovery
system, and R142b distillation system. After put into use, the stationarity of
key process parameters was increased by 69.2%, and the automation rate reached
90.74%, which greatly improved the stability of production and reduced labor
intensity. Meanwhile, the steam consumption was reduced by 21.3%.
The 701 (AHF) unit covered seven units,
including fluorite drying system, acid feeding system, reaction system, product
refining system, tail gas system, gas pickaxe system, and oil pump system. After
put into use, the stationarity of key process parameters was increased by more
than 50%, and the automation rate reached 95.18%.
“It turned out that the operation effect is
remarkable after comprehensive review by the expert group. All the technical
indicators meet the contract requirements. The project documents are standard
and complete. All agree to pass the acceptance.” declared by the expert review
group leader of Juhua Group Corporation.
