the technical reformation measures were adopted,i. e. the CO_2 gas circulation washing device was added between the de-carbon regenerator in ammonia synthesis loop and the separator at the first stage inlet of CO_2 compressor of urea plant,after reformation the pressure difference of de-hydrogen reactor was maintained always at 60~65 kPa within five months,6 months later,this pressure difference was also only 85 kPa;
A combined equipment scrubbing cooking fumes was designed and the model experiment were dynamically done to study the optimum of operation with freshwater as the scrubbing medium.
The characteristics of this shunt include a large-caliber catheter, a very low pressure slit valve, and a one-piece design with a large flushing device.
This required improvements in the flume water supply, construction of sand-washing equipment, and the use of defined clay and sand preparation procedures.
This required improvements in the flume water supply, construction of sand-washing equipment, and the use of defined clay and sand preparation procedures.Flume experimental result-, indicate that clay is extensively trapped by the bed.
A high-throughput antibody staining and washing system for large-scale routine indirect immunofluorescence testing was developed, using a robotic sample processor.
