【正文】 easy to be blocked, it is not appropriate treatment of dirty, viscous and with solid particles in liquid.This design topic is the separation of benzene and chlorobenzene rectifying tower design, namely the design of a distillation column used for the separation of volatile benzene and chlorobenzene not volatile, with continuous operation, the specific process parameters are as follows: Processing capacity: 12000 tons / year Liquid position (containing chlorobenzene): 34% Product position (chlorobenzene purity): 99% Overhead product position (containing chlorobenzene: ≤ %) Operating pressure: the pressure 4KPa (gauge) Thermal conditions of feed and reflux ratio of optional Tower bottom heating steam pressure: (gauge) Single plate pressure drop: ≤ Earthquake intensity: 7 degrees Soil conditions: second types of site soil Local pressure =100kPa Equipment working time: 300 days (day 24 hours of continuous operation) Power supply: source of water is enough, the normal power supply For the 16MnR, =0 plate negative deviation, thus the nominal for low alloy steel vessel, shall not include corrosion allowance minimum thickness shall be not less than 3mm, with 5mm corrosion allowance, nominal thickness of at least 8mm. Because the head partially warp curvature change is smooth and continuous, so the stress distribution is relatively uniform, and semi spherical head elliptical head depth is much smaller, easy forming, is present in low pressure container, which is often applied in the design of elliptical head. Tower of the hand hole is the operator of the tower for inspection and repair design of hand hole DN250 welding neck flange hole. The process needs to take over, in the tower design over size are DN32, DN50, DN65, DN80, DN125, all connecting pipes are not reinforced.9
