Experimental results show the recognition rate of the method is 95%for a known expresser and 72% for a novel expresser. Aiming at the shortcomings of optical flow technique,two improved optical flow algorithms are presented.One way is to introduce forward and backword constraint eqution and Hessian matrix of optical flow equation is computed.The well- posedness of each point of local neighbourhood is examined and the weight of Lucas-Kanade's method is defined as the reciprocal of the conditioning number of its Hessian Matrix.

It showed that the propane recovery rate of new process would be 23%~27% higher than that of cryogen refrigeration process at the same refrigeration temperature. To increase the absorption tower pressure appropriately was good to improve the propane recovery rate. However, the choice of pressure must take the pressure of the feed natural gas and product gas into account together. The flow rate of absorbent had great effect on propane recovery rate and tower heat load.
