Comparison of internal and external heating distillation technology

Type	Distillation Temperature	Vacuum Degree	Capacity	Yield	Glycerol treatment	Product quality
Type	Distillation Temperature	(Kpa)	（T/D）	Yield	Glycerol treatment	Product quality
Internal coil heating	180~210	6~8	10~100	Low	OK	Low
External circulation heating	150~170	0.2~0.3	50~300	High	Not recommended	High

The advantages of external circulation heating glycerol technology are:

The technology of external circulation and low energy consumption is equal to the existing technology.
The treatment temperature is below 160 degrees, which greatly reduces the generation of decomposition and polymerization.
The circulating cooling water is not contacted with the system, and it will never pollute.
Glycerol residues from non glycerol organic matter and polyglycerol are sold as industrial auxiliaries after desalting.
The salt in raw material is on-line continuous separation technology, which is mainly removed in solid form, and it can be sold as industrial salt.
Environmental design also achieves excellent level. The whole system is designed with negative pressure, without any sensitive gas leakage. At the same time, the sewage produced by the system is minimized and completely cleaned, sent to the sewage treatment center to deal with the discharge of the standard.
The water circulation pump adopts the technology of circulating closed water, which greatly saves the fresh water consumption.
Energy recycling is maximized, and processing cost is highly competitive.
A full set of DCS designs, continuous import and export, smooth operation, excellent quality and minimum labor force.
The circulating cooling water is not contacted with the system, and it will never pollute.
The yield of distillation is 2-3 percentage points higher than that of traditional process.
80% of the finished products were obtained with a high content of 99.9
