Abstract:

As crude benzole recovery rate is low,the factors affecting the crude benzole recovery rate are analyzed. Improvement measures such as reducing the resistance of benzole scrubber,increasing circulating wash oil flow,reducing the absorbing temperature of benzole scrubber,increasing reflux of crude benzole still and improving the quality of circulating wash oil,have been taken to improve the crude benzol recovery rate.The average crude benzole recovery rate is improved to 0.91% from 0.8%.
