Abstract

The invention discloses petrochemical process parameter measurement experimental equipment based on a safety interlock system. The equipment comprises a sieve plate rectifying column device, a packing absorbing column device, a universal valve performance tester and a measurement and control system for controlling the devices above to operate. The sieve plate rectifying column device comprises a sieve plate rectifying column, a feeding system, a reflow system, a bottom steam generating system, a product outlet pipe and a residue outlet pipe; the packing absorbing column device comprises a packing absorbing column, a mixed gas supply system, a water supply system and an ammonia absorbing device. The universal valve performance tester comprises a gas supply system, a liquid supply system and a valve test bed. The front end of the valve test bed is connected with the gas supply system and the liquid supply system. A reflux ratio experiment of the sieve plate rectifying column, a flooding experiment of the packing absorbing column and a universal valve performance test are integrated, experimental data guides the design of related complete column equipment and research on valve performances, and the whole equipment is high in integrity level and compact in structure.

Description

technical field [0001] The invention relates to an experimental device for measuring parameters of a petrochemical process based on a safety interlock system. Background technique [0002] The reflux ratio, flooding point, and valve flow coefficient are important parameters in the petrochemical process. The selection and control of related parameters are the key to the normal operation of the corresponding process engineering. [0003] The reflux ratio is an important parameter for the design and operation of the distillation column. The reflux ratio not only affects the required theoretical plate number, column diameter, and structural size of the plate, but also affects the consumption of heating steam and cooling water. The selection range of the reflux ratio is at the minimum reflux ratio R min to infinity. If the selected reflux ratio is too small, the number of theoretical plates required will be large, and the equipment investment cost will be large. If the selecte...
