Description
Technical field
The utility model belongs to the testing apparatus of laboratory evaluation mink cell focus heat scission reaction situation, is a kind of testing apparatus that vacuum residuum pyrogenic reaction process subtracts Jiao, increases the liquid effect that is used for estimating specifically.Be applicable to laboratory evaluation mink cell focus heat scission reaction situation, mainly be to investigate, explore the certain law that the mink cell focus thermo-cracking is converted into coke, light-end products and gas, be specially adapted to estimate vacuum residuum and add behind the various auxiliary agents and to reduce the fouling coking, to improve the effect aspect total liquid oil yield, for reduce production energy consumption, prolong operation cycle, optimize product structure, increasing economic efficiency provides reference information accurately.
Background technology
Delayed coking is the hot procedure that vacuum residuum is converted into gas, liquefied gas, liquid oil (gasoline, diesel oil, wax oil) and coke through degree of depth thermo-cracking, be the main means that refinery improves yield of light oil and produces petroleum coke (CHx, wherein x＜1).Delayed coking is compared with residual hydrocracking, heavy oil fluid catalytic cracking, has that facility investment is few, production technique simply reaches advantages such as process cost is low.Delayed coking is the technology of domestic and international heavy oil deep processing first-selection.
One of improved important goal of delayed coking unit Technology, even if reduce boiler tube (comprising the transfer line of outlet of still) fouling coking, prolong operation cycle, minimizing coke and dry gas (hydrocarbons of C1 and C2) to coke drum productive rate, increase liquid oil (preferably lightweight oil such as gasoline, diesel oil) yield.Consider from changing feedstock property and processing condition both at home and abroad always.Improving raw material can be with the coking again of vacuum residuum elder generation's hydrogenation, and this method not only can improve liquid greatly to be received, but also can improve quality product, but the investment of this method and process cost are too high, economical profitless.Operation conditions optimization mainly is by reducing recycle ratio, reduce pressure, improving various operation measures such as temperature and separation column deep drawing wax oil, improve liquid yield, but these methods can be quickened boiler tube (comprising the transfer line of outlet of still to coke drum) fouling coking, shorten the operational cycle.
By in coking raw material vacuum residuum, adding various additives, reduce heating furnace tube (comprising the transfer line of outlet of still) fouling coking, reduce coke and dry gas generation to coke drum, be that prolong operation cycle, raising liquid are received the most convenient effective means.At present, have both at home and abroad and in delayed coking process, use various additives, reduce the fouling coking, improve the research of liquid yield and use report.At present testing tool that vacuum residuum heat scission reaction green coke is estimated or device have common coking testing tube, liner respectively with clean aluminium telescopic static reaction system, and small fixed reactor test device, small-scale fixed bed pilot plant, specific heavy oil hot workability are estimated instrument etc.But, be difficult to contrast even the result occurs mislead because various evaluating apparatus differences cause the gained data deviation very big.In addition, these evaluation appts or testing apparatus troublesome poeration, test is consuming time, error in dipping is big.
