Factory of rubber of Qi Lu petrifaction is from 2007 on device of second nitrile butadiene promotion used flow imitate technology, use platform of this one advanced technique to optimize craft to operate a condition ceaselessly, achieved energy-saving fall the bad news, remarkable result that increases benefit.
This factory finished second nitrile device to build a model to work at using software of foreign flow simulation last year, debug via relapsing, make imitate data be identical the requirement that actual production process bolts to all closing quality dominates index, establish imitate flow is directive to what produce actually action. Technical personnel applies this one technology to strengthen the research computation of a certain number of pair of elements that influence device runs, provided a basis to optimize operation and craft to transform, came true successfully to study positive result to productivity change.
Through imitate computation optimizes T206 tower sidetrack to adopt the control method that gives content shedding, make butadiene loss was reduced by 20% above 5% the following, can reduce butadiene loss every year more than tons 120, year achieve effect more than yuan 120. The parameter when extractive hillock changes through mastering bear adjusts the rule stabilizes technology operation, reduced butadiene product unqualified cycle time, every reduce a loop 1 hour to be able to reduce vapour to use up 18 tons, increase production butadiene 7 tons, achieve effect more more than yuan 10 thousand. According to imitate result, put in T208 tower briny refrigeration is added to reclaim in empty flow system, condensation of part of the butadiene in making put empty tail gas, reclaim, annual but increase production butadiene is controlled 100 tons, raise device to produce further can.
