CO2 stripping process, CO2 flow rate problem?

The elbow flowmeter is a differential pressure flow measurement system. When the fluid passes through the elbow sensor, the fluid is restrained by the sensor, forcing the fluid to make a similar circular motion in the pipe according to the curvature of the elbow. The centrifugal force generated by the fluid causes a pressure difference ΔP (P1-P2) on the inner and outer walls of the sensor. The size of the centrifugal force is related to factors such as the fluid's flow rate V, density ρ, and the radius of curvature R of the circular motion. The pressure difference is detected through a differential pressure transmitter and converted into a 4-20Ma signal output to a microcomputer or secondary instrument. 　　Elbow flow meters can be divided into L type and S type according to the installation method. ； According to the shape of the tube, it can be divided into round tube type elbow flow meter and square tube type elbow flow meter. 　　Bend tube flow meter features: It has a wide range of applicable measurements, high reproducibility and measurement accuracy, no additional pressure loss, good wear resistance, long service life, and low requirements for straight pipe sections (meeting 5D before and 2D after). ； It can be installed by direct welding, which reduces the workload of on-site maintenance, has low operating costs, and can realize online compensation of temperature and pressure.

What are the requirements for the front and rear straight pipe sections of a long-life curved tube flowmeter? Answer The straight pipe section requirement for L-type and S-type elbow flowmeters is 5D in front and 2D in back. What are the specific installation requirements for elbow flow meters? Answer: The installation of the elbow flowmeter is a very important link. It is related to whether the elbow flowmeter can be used normally and whether its accuracy can be guaranteed. First of all, when installing the elbow sensor, ensure that the pressure sensing bodies on both sides are on the same level. In addition, the entire elbow sensor must be kept level. If you are measuring steam, when installing the disc condenser, you must also ensure the overall levelness of the disc cooling on both sides. For the installation of other components, please refer to their instructions. Why is the elbow flow meter an energy-saving product? Answer: The elbow flow meter is a differential pressure flow meter. Its core pressure-taking component, the elbow sensor, does not have any inserts or flow obstructions. In use, the L-shaped elbow sensor only needs to replace the elbow at the bend of the original pipeline. Therefore, it does not produce additional pressure loss and is an energy-saving product compared with other flow meters. The S-type elbow flowmeter will produce a certain additional pressure loss, which is very small compared with other flowmeters. Does the ZWL2000 elbow flowmeter have an output function? Answer: The host meter of the ZWL2000 elbow flowmeter can be equipped with 4-20MA, RS232, and RS485 interfaces. What media are suitable for measuring by the elbow flowmeter? Answer: As long as it is a medium with low viscosity, the elbow flowmeter can accurately measure. Due to the characteristics of the elbow flowmeter, the media that are more suitable for measurement include steam (superheated and saturated steam), circulating water for heating, chilled water for air conditioning and refrigeration units, various gases (blast furnace, coke oven, converter gas), compressed air, natural gas, sewage, etc. What media can elbow flowmeters successfully measure today? What are the areas of design? Answer: The media that the elbow flowmeter can successfully measure include heating water, superheated steam, saturated steam, chilled water, blast furnace gas, coke oven gas, converter gas, compressed air, combustion air, induced air, sewage, liquid ammonia, nitrogen, oxygen, acetylene, diesel, transformer oil, natural gas, dehydrogenation tail gas, etc. ； Application fields include heat, thermoelectricity, iron and steel metallurgy, coking and gas production, tobacco, petrochemicals, papermaking, food processing, environmental protection, building materials and other fields. The elbow flowmeter has certain requirements for the on-site environment. Are you afraid of vibration? Answer: The elbow sensor, the primary component of the elbow flowmeter, has no special requirements for the site environment and can be used under general industrial site conditions. The host meter of the elbow flow meter is generally required to be away from strong interference sources. It is best to use shielded wires for signal lines and lay them separately from the power cord (consistent with other host meters). There are no special requirements. What is the price of elbow flow meter? Answer: The price of the elbow flow meter is slightly higher than that of the orifice flow meter. The gap narrows as the pipe diameter increases. However, in view of the no pressure loss and maintenance-free characteristics of the elbow flow meter, its cost performance is unmatched by the orifice flow meter. The elbow flow meter is an energy-saving flow meter. How is its energy-saving data calculated? Answer: Compared with differential pressure flow meters such as orifice plates, elbow flow meters have no additional pressure loss and are energy-saving. The calculated values ​​are also based on this. For example, if the flow rate is 600t/h, the pressure loss flowing through the orifice flowmeter is 1mH2O column. If an energy-saving flowmeter such as a bend pipe is used, the energy saved is equivalent to 600×103×1×9.8=5880000 joules, which is equivalent to nearly 1.65 degrees of electricity. If it runs all day, it can save nearly 40 degrees of electricity every day. The introduction here only covers the content of power consumption. The energy loss caused by pressure loss that reduces the quality of transported energy varies according to different industries and will not be covered here. To sum up, the cost of the elbow flow meter can be recovered within one year through the benefits of energy saving. The S-type elbow flowmeter has a slight pressure loss due to its installation on a straight pipeline. What is the accuracy level of the elbow flow meter? Answer: Nowadays, the system accuracy of elbow flow meters can be guaranteed to be within level 1.0. It has been confirmed both in practice and in the process of real flow calibration. The theory and application technology are quite mature and there are no major doubts. This is inseparable from the diligent research of many experts and scholars and the large amount of practical work by many elbow flow meter manufacturers. It is also inseparable from modern bending processing technology and ever-changing computer technology (especially single-chip microcomputer technology). How do you understand the process of understanding elbow flow meters? Answer: As a kind of flow meter, elbows have been used in industrial applications for more than a hundred years. There are many textbooks and textbooks on flow meters. * * The calibration regulations of differential pressure flow meters have been introduced as a type of differential pressure flow meters. However, the understanding of the characteristics of this flow meter is different in different eras, and some views are even tit for tat. This mainly focuses on aspects such as accuracy, whether geometric calibration is necessary or real flow calibration is required, and requirements for installing straight pipe sections. However, they are completely consistent about the flow meter’s no pressure loss, high reproducibility (0.2%), and the insignificant impact of fouling and wear on accuracy. What are the types of elbow flowmeters? Answer: Since the development of elbow flow meters, the specific types commonly used in industry include L-type elbow flow meters used in 90° turns, S-type elbow flow meters used in straight pipelines, and elbow flow meters used in 135° pipeline connections. Its leading types are L-type elbow flowmeter and S-type elbow flowmeter. How to choose between temperature component and pressure transmitter? Answer: Whether devices such as temperature components and pressure transmitters are needed depends on the situation. Generally, superheated steam must be equipped, and saturated steam can only be equipped with temperature components. The principles for other media are as follows: Temperature and pressure have a great influence on the density of the medium, so it is generally required to be equipped with ； Temperature and pressure fluctuation ranges are large, generally requiring equipment ； The measurement medium has high accuracy requirements and is generally required to be equipped with ； If there are requirements for heat measurement, a temperature component must be equipped.
