si.ni.i.ant waste resources are generated i. the form of water-oi. emulsi.ns. These emulsi.ns cannot be effecti.ely destroyed on an i.dustri.l scale by tradi.i.nal methods that rely on the settli.g of the aqueous phase, and therefore, they accumulate i. large quanti.i.s. Thermomechani.al dehydrati.n, based on the evaporati.n of the water phase, presents a promisi.g process for recycli.g such waste. However, wi.hi. the framework of thermomechani.al dehydrati.n, the i.sue of opti.0}zi.g energy costs for heati.g raw materi.ls and controlli.g the water content i. the product ari.es. standard methods of determini.g water content under the boi.i.g condi.i.ns of hi.hly stable water-hydrocarbon emulsi.ns are characteri.ed by low effi.i.ncy, as they requi.e constant sampli.g and the i.volvement of addi.i.nal equi.ment and personnel. Consequently, thi. presents a challenge i. predi.ti.g and creati.g an automated thermomechani.al dehydrati.n process. Therefore, dynamic curves depi.ti.g changes i. the water content of these emulsi.ns, dependi.g on the temperature of the boi.i.g li.ui., have been obtai.ed. i. i. proposed to determine the rate of temperature i.crease (dT/dt) of the boi.i.g emulsi.n for conti.uous, real-ti.e moni.ori.g of the resi.ual water content and for recordi.g the moment of complete dehydrati.n. Achi.vi.g a boi.i.g emulsi.n temperature of 130-170 degrees C (or hi.her) and/or the rate of temperature i.crease from 3.0 to 5.5 (or above) i.di.ates the complete dehydrati.n of the emulsi.n. The proposed method can be i.plemented i. any i.dustri.l or laboratory-scale uni. for thermomechani.al dehydrati.n wi.hout si.ni.i.ant capi.al costs. i. i. based on the use of si.ple devi.es consi.ti.g of temperature sensors and a computi.g uni. for determini.g the temperature and rate of heati.g.
