The invention belongs to the technical field of extraction, and discloses a method,
system and application for recovering high-value
liquid ammonia and
protein from
glutamic acid waste
mother liquor, and the method comprises the following steps: extracting
mycoprotein from
glutamic acid waste
mother liquor, concentrating, feeding into a reaction tank, adding an
ammonia gas decomposing agent into the reaction tank, controlling the pH value, continuously stirring, and carrying out
solid-liquid separation; the solution violently reacts and releases dilute
ammonia gas, and the
ammonia gas is compressed, sterilized and conveyed to be fermented to be used as a
nitrogen source; performing
solid-liquid separation on the
mother liquor to obtain salt
solid products for sale, and preparing the separated mother liquor into feed for sale. According to the novel green method for extracting the
ammonia gas from the
glutamic acid waste mother liquor and efficiently recovering the
protein feed, the mother liquor is subjected to
component analysis, different methods are adopted for separation according to different components, high-added-value products ammonia and
protein are extracted and separated, green
recovery is implemented, the added value and the overall value are improved, the
environmental protection problem is solved, and the method is worthy of popularization and application. The economic benefit is achieved, and meanwhile the great social value is achieved.
