According to the daily water quality analysis and laboratory results, supplement the discharge water and control the dosing amount to make it reach the required data index. When the turbidity is >20mgL, increase the amount of drainage water, increase the flow of side filtration, and supplement clean water. According to the current situation of the circulating water system, try to increase the concentration multiple operation to save water and medicine. If the concentration multiplier is g...

Before the air cooling columnand water cooling columnare hoisted in place, the anchor hole shall be cleaned, and there shall be no water and debris in the anchor hole.   After the air cooling columnand water cooling columnare hoisted in place, the perpendicularity of the equipment shall be checked. The perpendicularity shall be ≤ 1/1000 and the total length shall not exceed 10mm.   The bottom of the anchor bolt shall not touch the bottom of the reserved anchor hole. Af...

What are biogas purification technologies

The stroke of the valve plate of the piston compressor valve of the small air separation unit should be reasonably selected according to the speed and pressure of the compressor and should not be too large or too small. If the valve stroke is too large, the valve blade may not open fully and may also close with a hysteresis due to the inertia of the moving parts. At the same time, if the stroke is too large, it will increase the speed of the valve blade when opening and closing, and the impact o...

Why is two-stage distillation column widely used in air separation column?

What is the definition and function of reflux ratio in air separation distillation?

To determine whether the heat exchanger has thermal scale: a. View the last 3 to 6 months of the heat exchanger convergence temperature (gas temperature inlet water temperature) annual convergence temperature rise greater than 2 ℃ per year. b. If the convergence temperature has increased significantly more than 0.5 ℃ per month, indicating the existence of problems. Treatment options. Slight thermal scale (convergence temperature rise less than 0.5℃/month): firstly reduce the concentration of...

In the upper column fractionation, below the liquid air inlet is called the stripping section, and above the liquid air inlet is called the distillation section. The stripping section realizes the separation of oxygen and argon, and the distillation section realizes the separation of oxygen and nitrogen. Because the boiling points of oxygen and argon are relatively close, the separation is difficult. In order to ensure the purity of oxygen, the separation of oxygen in the distillation section is not clean, and argon escapes with oxygen and nitrogen. If high purity nitrogen is to be obtained, argon will condense with oxygen in the distillation section, which will affect the purity of oxygen. In order to ensure the purity of oxygen and obtain high purity nitrogen, it is necessary to extract part of the gas with high argon concentration in the distillation section.
