Abstract
The invention refers to ammonia sulfate utilization patterns in the process of lysine, the characters of which include the evaporation and concentration of wastewater (mother liquid) after refining and separating lysine; in which the ammonia sulfate separated by crystallization is recrystallized, purified and separated, afterwards is sent back to fermentation production used as raw material; the waste mother liquid after fractional crystallization of ammonia sulfate is used for raw material in producing composite fertilizer. The technical project in recycle of ammonia sulfate introduced in the invention realizes the reasonable recycle and the cycle comprehensive utilization of useful ammonia sulfate in wastewater (mother liquid), that not only reduces the solid in wastewater and also realizes the cycle comprehensive utilization of raw material. That has suitable control condition and obvious economic value.
Description
Technical field:
The invention belongs to bioengineering field, relate to the Methionin production method, the recovery and the comprehensive utilization of ammonium sulfate in the fermenting lysine waste water specifically.
Technical background:
Methionin is one of eight kinds of primary amino acids of needed by human.Methionin and Threonine are topmost amino acid in the Animal nutrition, because other several seed amino acids general equal can replacement by analogue or the compact optical isomer with X-ketone group or hydroxyl.But Methionin is unique only L-type composition in eight seed amino acids could effectively be utilized.Because Methionin can not generate by reduction amination effect or transamination in human body, must be by absorbing in the food, so it is a kind of most important primary amino acid.
In recent years, fodder industry and foodstuffs industry fast development both at home and abroad, the purposes that Methionin is new on the medicine industry constantly is found, and Methionin has become good development prospect on a kind of world market, the bigger product of breach on the domestic market.
The production method of Methionin has extraction process, chemical synthesis and enzyme process and fermentation method.Produce the large-lot producer of Methionin in recent years in the world, most direct fermentations that adopt.
The raw material of fermentative Production Methionin is mainly glucose, soybean meal hydrolysate and ammonium sulfate.The consumption of ammonium sulfate accounts for fermented liquid gross weight 4～5%, ammonium sulfate is the mainly inorganic nitrogen-sourced of Methionin, need add in the substratum with the organic nitrogen source soybean meal hydrolysate, during the fermentation, growth along with thalline, the nitrogenous source of substratum constantly descends, and sulfate radical can constantly increase in the fermented liquid, and at this moment needing continues to flow adds ammonium sulfate and feed liquid ammonia and replenish nitrogenous source; Fermentation finishes, and puts into the fermented liquid storage tank, decomposes in order to prevent Methionin, needs to regulate with sulfuric acid the pH value of fermented liquid, and at this moment the ammonium sulfate of fermented liquid has increase again; Fermented liquid is through refining purifying, and ammonium sulfate will all enter in the waste water.
Current, the mode of manufacturing compound manure is handled the ammonium sulfate in the fermented liquid waste water after the majority Methionin manufacturer employing evaporation concentration, though this mode has also found the home to return to for ammonium sulfate, but utility value is low excessively, particularly there is a large amount of sulfate radicals in the waste water, bring in the fertilizer the growth of farm crop, particularly the farmland soil property is all had negative effect, not welcome by the peasant.
Summary of the invention:
For the ammonium sulfate in more rational recovery and the comprehensive utilization Methionin factory effluent, the inventor has proposed the technical scheme that ammonium sulfate is recycled in the Methionin factory effluent.
Technical solutions according to the invention are that the waste water (mother liquor) behind the refining separation Methionin is carried out evaporation concentration; The ammonium sulfate that crystallization is wherein separated out carries out recrystallization, purification, separation, sends back in the fermentative production then to recycle as raw material; Waste liquor behind the Crystallization Separation ammonium sulfate is as the processing composite fertilizer material.
Evaporation concentration equipment and working method can be selected for use with reference to routine techniques, but the degree of evaporation concentration is to embody the key that overall evaluation of a technical project of the present invention utilizes economic worth.Concentrating degree is not enough, does not reach the purpose that ammonium sulfate recycles and reuses, and concentrating degree is too high, does not calculate on the economic worth.The inventor confirms after multiple factors such as overall equilbrium energy consumption, recovery product, recirculated water and appointed condition and technological operation convenience, the weight of the ammonium sulfate that waste water evaporation concentration extent control is gone out in Crystallization Separation reaches 45%～55% of ammonium sulfate gross weight in the waste water, is the optimal selection scheme of the inventive method.
Ammonium sulfate recovery and utilization technology scheme of the present invention, reasonably reclaim and recycle have in the waste water and utilize the ammonium sulfate that is worth, both reduced the cured article in the waste water, realized the circulation comprehensive utilization of raw material again.Its control condition is reasonable, and economic worth is considerable.
Embodiment:
Be example now, analyze the value of implementing this programme with the production line of producing 60000 tons of Methionins per year.
In this production line, need to consume about 30,000 tons of ammonium sulfate raw material/year, by the technical program recovery 50%, the ammonium sulfate of recycling reaches about 1.5 ten thousand tons, can create 9,000,000 yuan/year of economic worths.Waste liquor processing composite fertilizer also can create new value in addition.
Claims (2)
1, in the Methionin production ammonium sulfate utilize method, it is characterized in that the refining waste water that separates behind the Methionin is carried out evaporation concentration; The ammonium sulfate that crystallization is wherein separated out carries out recrystallization, purification, separation, sends back in the fermentative production then to recycle as raw material; Waste liquor behind the Crystallization Separation ammonium sulfate is as the processing composite fertilizer material.
2, according to claim 1 in the Methionin production ammonium sulfate utilize method, the weight of the ammonium sulfate that the extent control that it is characterized in that said waste water evaporation concentration goes out in Crystallization Separation reaches 45%～55% of ammonium sulfate gross weight in the waste water.
