Abstract
The invention provides a triethyl phosphite neutralization temperature adjusting method. The neutralization temperature is decreased through using process circulating water, and the neutralization temperature after cooling is controlled at 20-30DEG C. The method can reduce the electricity consumption, and changes refrigerated brine cooling to process circulating water cooling in order to guarantee the temperature, so the steam consumption is reduced, and energy saving and environmental protection are realized. The method is suitable for being used as a triethyl phosphite neutralization temperature adjusting method.
Description
Technical field
What the present invention proposed is the NSC 5284 neutral temperature method of adjustment of chemical field process control art.
Background technology
Original process condition: Phosphorous chloride., dehydrated alcohol, purified petroleum benzin, triethylamine are measured through effusion meter, is continuously added to reactor by a certain percentage, react reaction of formation liquid.Reactant liquor continuously enters neutralization still, and the aqueous slkali adding metering is neutralized.Neutral temperature is-5～5 DEG C, and the neutralizer after neutralization continuously enters layering tower, and the thick ester containing NSC 5284 is dried through exsiccator.Isolated process spent water enters recovery tower and carries out solvent recovery, processes subsequently into sewage disposal system.Dried dry ester, through distillation, is isolated highly purified NSC 5284 and is entered groove, as finished product sale to be packaged.Purified petroleum benzin after separation, triethylamine return to synthesis procedure and recycle.
Summary of the invention
In order to make full use of reaction heat, the present invention proposes NSC 5284 neutral temperature method of adjustment.The method is adjusted by neutral temperature, solves the technical problem that reaction temperature adjusts.
The present invention solves the scheme that technical problem used:
Neutral temperature process recycled water is lowered the temperature, and after cooling, neutral temperature controls at 20～30 DEG C.
Good effect, the present invention can reduce the consumption of electricity, and before improving, neutral temperature need to be lowered the temperature with chilled brine, ensures temperature with process recycled water, thus decrease steam consumption after improvement, the most energy-conservation but also environmental protection.Suitably use as NSC 5284 neutral temperature method of adjustment.
Detailed description of the invention
Neutralizing reaction temperature process recycled water to lower the temperature, after cooling, neutral temperature controls at 20～30 DEG C.
Improvement advantage:
1, reducing the consumption of electricity, original temperature need to be lowered the temperature with chilled brine, uses process recycled water after improvement；
2, reducing steam consumption, the solvent drying tower to be entered after layering is dried, and need to heat up with steam, and after improvement, solvent temperature promotes, thus reduces steam consumption.
Claims (1)
1. NSC 5284 neutral temperature method of adjustment, is characterized in that: neutralizing reaction temperature process recycled water and lower the temperature, after cooling, neutral temperature controls at 20～30 DEG C.
