Although production can take place in loads, it is recommended that the method be performed continuously, wherein a duration time in the reactor is maintained lying between 2 and 250 hours, in general between 5 and 200 hours.
  • the quantity of organic compound produced depends on the conditions but lies for amino acid in general between 0.5-5 g amino acid per gram of ammonia; for instance, with sufficient ammonia in the condensate 80 to 90% of the theoretically maximum feasible fermentation efficiency can be achieved, such as for instance 40 g lysine per litre of condensate.

The mixture of concentrated condensate and nutrients is neutralized to pH 7.2. The condensate is subsequently fed to a reactor 120 in which micro-organisms are oculated. Through the specific composition of the condensate the micro-organisms will mainly grow and increase strongly in biomass. The increase in micro-organisms is fed via a conduit 121 to another reactor 122. Further fed to this reactor 122 via the conduits 116 and 123 is concentrated condensate from the concentration device 115. Used condensate that leaves the reactor 120 via the conduit 124 can optionally also be fed to the reactor 122.
  • the condensate serves as substrate for the micro-organisms for the production of the amino acid, namely 1-lysine or 1-methionine.
  • the mass which leaves the reactor 122 via the conduit 125 is filtered in the separating unit 126 into a biomass fraction which is fed back via the conduit 127 to the reactor 122.

  • a second known processing process is the so-called Greenfield process (US-3.855.079, US-4.270.974 and US-4.608. 120) .

The biogas formed during the biological degradation can be used in the processing process, see further "Natuur en Techniek" 52, 894-903 (1989) .
  • the invention is based on the insight that present in manure are valuable, volatile organic compounds which are economically separable from the manure if condensate is re ⁇ moved from the manure without prior fermentation thereof and this condensate is subjected to a suitable physico-chemical separation process for separating the volatile organic com ⁇ pounds.

  • Suitable extraction agents is the group of higher alkylamines. Preferred are trialkylamines, in particular trioctylamine and di-tridecylamine. For further information regarding the use of amines in liquid extraction reference is made to N.L.Ricker et al, J. Separ. Proc. Tech- nol. 1, 23-30, (1980) .

  • These means can for instance be embodied such that steam or water is injected herewith into the flame.
  • Another possibility is to mount the burner in a water-cooled furnace tube. The flame can then rapidly transfer heat to the relatively cool wall of the furnace tube through radiation.
  • the boiler is preferably embodied as a fire tube boiler. Since a relatively large quantity of ash constituents can be released during burning of manure fat, the boiler can quickly become dirtied.
  • a fire tube boiler has in contrast to a water tube boiler the advantage that it can be cleaned quickly.
  • Another favourable embodiment of the combustion boiler is one wherein a heat resistently walled cyclone for separating dust is arranged between the burner and the heat exchanger. Because a consider-able portion of the dust ash formed during burning of the manure fat can be separated from the hot flue gases, the heat exchanger of the boiler connected thereafter remains to a considerable extent free of dirt so that the cleaning frequency will be markedly lower.
