The characteristics of TongHui Batchpoly Engineering: | |||||||
>15t/d--100t/d Polyester Batch Polymerization Plant Characteristics | |||||||
Maximum running flexibility with various of compact & precise additive dosing units to produce speciality products |
|||||||
2-reactor or 3-reactor process can be available as different plant selection |
|||||||
2 nd esterifier or pre-poly can be added for the speciality production convenience |
|||||||
Esterification is proceeded continuously to reduce batch cycle time, and keep esterification running stably |
|||||||
Low temperature, low mol ratio, mild reaction; |
|||||||
Low material and utility consumption with high operation economic property; | |||||||
Low DEG content, low oligomer content; | |||||||
> Plant Design | |||||||
Tonghui offers 15-100tpd batch polymerization plant for different end users like yarn or staple fiber spinning, chip production, film stretching; The design can be also tailor made to meet for individual demands or speciality production; | |||||||
Three stage EG ejector can
be applied for vacuum supply to pre-poly and autoclave which can reduce
MEG consumption and effluent drainage Full automatic computer control system is applied, all process data can be monitored and controlled by the control system; Reverse control for liquid level is applied for reaction vessels, that the liquid level of each vessel controls the material feeding to ensure the balance processing of the polymerization; The control model set by IV figure from driving currency of autoclave agitator can justify the formula between vacuum and IV to gain stable IV; Protection alarm and safety interlocks are set in the major control loom and equipments to ensure the safe running of the batchpoly line, emergent stop system is also set to ensure the safe stop in case of necessary. |
