OP-III-B-11STATE-OF-THE ART REACTOR DESIGNFOR HIGH-CAPACITY OIL-REFINING PROCESSKapustin V.M.OAO VNIPIneft;Gubkin Russian State Oil & Gas University, Moscow, RussiaE-mail: vkapustin@vnipineft.ruAt present, special attention is given to an oil conversion degree. Increasing theoil conversion depth and upgrading heavy ends are achieved due to presence ofdestructive processes in process flow diagrams of refineries. Destructive processesare presented by various chemical reactions: cracking, hydrogenolysis,hydrogenation-dehydrogenation, dehydrocyclization, alkylation, isomerization,polycondensation, etc. These processes run in special-purpose vessels, so-calledreactors. A reactor design depends on peculiarities of a particular reaction andprocess conditions (temperature, pressure, catalysts available, etc.).Permanent improvement of technologies and development of new efficientcatalysts contributes to modernization and creation of new reactor equipment. In turn,emerging new structural materials offers the opportunity for changing the conditionsof chemical reaction, using next-generation catalytic systems and necessitatesdeveloping and creating of new reaction facilities.Of particular interest is the evolution of a catalytic cracking reactor-regeneratorblock, having been updated concurrently with development of catalytic systems, froma moving-bed reactor to a riser A trend to involve heavy petroleum feedstock andresides in processing necessitates modernizing a regeneration unit with a specialheat-rejection device, developing special feeding equipment for reactors and creatinga fundamentally new ultra-short contact time reactor (millisecond reactor).A number of new design solutions have been used for the reactor of a new VGOcatalytic cracking complex of OAO TAIF-NK in Nizhnekamsk built on the basis of adomestic technology developed by INKhS RAN, OAO VNII NP and OAO VNIPIneft.These R&D allowed achieving global competitive performance.Ever-heavier feedstock used in hydrocracking necessitates running processes ina moving catalyst bed, which, in its turn, results in more and more complicatedreactor design (H-Oil and LC-fining).200
