PROCESS AND INSTALLATION FOR PRODUCTION OF LIGHT HYDROCARBONS, GASOLINE AND DIESEL FRACTIONS Russian patent published in 2002 - IPC

FIELD: petroleum processing and petrochemistry. SUBSTANCE: light hydrocarbons are prepared from vapor-gas mixture via hydrocyclonation of preheated to 130 C petroleum, separated in gasoline separator into liquid hydrocarbons and gas. The latter, at pressure 12 kg/sq.cm and temperature 90 C, is fed into reactor through loose bed of catalyst, condensed, introduced into separator to yield isomerizate, which is mixed with light liquid hydrocarbons by bubbling through it. Under varied conditions, gasoline or diesel fraction can be produced. Gasoline or diesel fraction production plant is provided with tubular-type reactor filled by loose catalyst, diesel fuel and straight-run gasoline collection tanks, the first one being provided with bubbling device. EFFECT: enhanced process efficiency and enabled gasoline and diesel fuel production under oil-field conditions. 2 cl, 1 dwg
