METHOD OF PRODUCING GAS-FLUID REACTIONS IN SUB- AND SUPERCRITICAL FLUID

摘要

FIELD: process engineering.;SUBSTANCE: invention relates to continuous gas-fluid reactions in high-pressure tubular reactor. Proposed method comprises feeding, at least, one fluid reagent by gas reagent flow feeder 2, and, not obligatorily, by feeder 3. Note here that, at least, one initial flow is fed at supercritical pressure. It comprises also heating, at least, one said flow by heater 4 connected with feeder and combining said flows in jet mixer 5. Obtained gas-fluid mix reacts in direct-flow tubular reactor in, in fact, adiabatic conditions. Reaction mix flow is throttle via reducing device 7 into evaporating separator 8 at lower pressure with stripping gas flow comprising, mainly, low-boiling components from top part of evaporating separator 8, and liquid flow comprising, mainly, high-boiling components from bottom part of said evaporating separator 8. Note here that said flows are heated to temperature that allows interaction reaction in supercritical fluid. Aforesaid flows are combined in jet mixer 5 with gas-fluid mix rate of 10-350 m/s. Note here that time whereat combination occurs makes less than 1 second. Obtained gas-fluid mix interacts in direct-flow tubular reactor 6 that drastically reduces liner rate of said gas-fluid mix to 0.01-10 m/s. Note also that time whereat said interaction occurs makes less than 600 seconds.;EFFECT: higher reaction rate and target product yield.;25 cl, 3 ex, 1 dwg
