Abstract
The utility model discloses the device that season SAST's fat is reclaimed in a kind of raffinate from neopentyl glycol, including storage tank, compression pump, bottom of towe kettle, electric heater, rectifying column, condenser, vavuum pump, reflux ratio controller, collecting tank, pipeline.Neopentyl glycol raffinate in storage tank is squeezed into bottom of towe kettle by compression pump, then season SAST's fat steam is produced after electric heater is heated to certain temperature to rise in rectifying column, gaseous season SAST fat out enters cooling in condenser from rectifying column and is condensed into liquid, liquid enters split ratio controller by pipeline and shunted, a part delivers to rectifying column circular response, and a part, which is delivered in collecting tank, to be completed to collect.
Description
Technical field
The utility model belongs to technical field of petrochemical industry, is related to the accessory substance neopentyl glycol of hydrogenation method production neopentyl glycol
The technology application of raffinate, more particularly to from neopentyl glycol raffinate reclaim season SAST's fat device.
Background technology
Neopentyl glycol（NPG）It is with dihydric alcohol made from isobutanol and formaldehyde reaction.Due to symmetrical position in the molecule thereof
Put there is the hydroxyl rich in response characteristic, and central carbon atom does not have α-hydrogen atom, therefore, has other dihydric alcohol institutes
Some no special natures.The first step of neopentyl glycol production is the synthesis of hydroxy pivalin aldehyde, and the hydroxy pivalin aldehyde of generation exists
Under the catalytic action of base catalyst triethylamine, part disproportionation generation season SAST's fat.Ji Xianke fat, which is called, makees hydroxyl spy penta
Sour neopentyl glycol monoesters, abbreviation hydroxyl valeric acid monoesters（HPHP）, it is the valable starting materials for synthesizing high quality stability polyester resin, extensively
Applied to production colorful steel plate paint and polyurethane paint.Due to its molecular structure be containing saturation tertiary carbon atom structure and carbon chain length,
The features such as containing ester group, therefore not only stability is good for the polyester synthesized by it, while add the flexible of polyester and swing performance,
Make paint film that there is the performance such as stronger pressure-resistant, wear-resisting, anti-folding, flexible, be after neopentyl glycol, trimethylolpropane, pentaerythrite
Higher polyol of new generation afterwards.Because the boiling point of season SAST's fat is higher than neopentyl glycol, eventually with part neopentyl glycol with
The form of raffinate is discharged from system.Caused raffinate not only pollutes environment but also can cause pole during neopentyl glycol is produced
The big wasting of resources.
The content of the invention
To solve the above problems.The utility model proposes in a kind of raffinate from neopentyl glycol reclaim season SAST's fat device,
By maximum resource utilization, increase economic efficiency.
The device of season SAST's fat is reclaimed in a kind of raffinate from neopentyl glycol, by storage tank, compression pump, bottom of towe kettle, electricity
Heater, rectifying column, condenser, vavuum pump, reflux ratio controller, collecting tank, pipeline composition；It is characterized in that：Storage
Tank is connected by pipeline with compression pump；Compression pump is connected with bottom of towe kettle；Electric heater is connected with bottom of towe kettle, bottom of towe kettle with
Rectifying column is connected；Rectifying column is connected by pipeline with condenser；Condenser is connected with vavuum pump, condenser and reflux ratio
Controller is connected；Two outlets are connected with rectifying column and collecting tank respectively on reflux ratio controller.This device at work, is pressed
Power pump squeezes into the neopentyl glycol raffinate in storage tank in bottom of towe kettle, is then produced after electric heater is heated to certain temperature
Sheng Ji SAST fat steam is risen in rectifying column, gaseous season SAST fat from rectifying column out enter in condenser cool it is cold
Liquid is congealed into, liquid enters split ratio controller by pipeline and shunted, and a part delivers to rectifying column circular response, one
In dispensing to collecting tank.Vavuum pump is housed on condenser, device is kept negative pressure so as to change the boiling point of season SAST's fat, so as to
Bottom of towe temperature in the kettle need not reach its boiling point can Shi Ji SAST fat be changed into steam；Steam circulation can be separately set to accelerate to turn so as to be lifted
Become efficiency.
The beneficial effects of the utility model are：Season SAST's fat in neopentyl glycol raffinate is reclaimed using this device, reduces money
Source wastes and creates economic benefit.

Embodiment
As illustrated, in a kind of raffinate from neopentyl glycol reclaim season SAST's fat device, by storage tank, compression pump,
Bottom of towe kettle, electric heater, rectifying column, condenser, vavuum pump, reflux ratio controller, collecting tank, pipeline composition；It is characterized in that：
Storage tank is connected by pipeline with compression pump；Compression pump is connected with bottom of towe kettle；Electric heater is connected with bottom of towe kettle,
Bottom of towe kettle is connected with rectifying column；Rectifying column is connected by pipeline with condenser；Condenser is connected with vavuum pump, condenser
It is connected with reflux ratio controller；Two outlets are connected with rectifying column and collecting tank respectively on reflux ratio controller.Storage
Neopentyl glycol raffinate in tank is squeezed into bottom of towe kettle by compression pump, then produces season after electric heater is heated to certain temperature
SAST's fat steam is risen in rectifying column, and gaseous season SAST fat out enters cooling in condenser from rectifying column and is condensed into
Liquid, liquid enter split ratio controller by pipeline and shunted, and a part delivers to rectifying column circular response, and a part is sent
To collecting tank.Vavuum pump is housed on condenser, device is kept negative pressure so as to change the boiling point of season SAST's fat, so as to bottom of towe
Temperature in the kettle need not reach its boiling point can Shi Ji SAST fat be changed into steam；Steam circulation can separately accelerated so as to lift transformation effect
Rate.
