Inline Hydrochloric Acid Density Meter
Hydrochloric acid concentration is taken as the "speed regulator" or "steering wheel" in chemical synthesis process. Precise measurement of hydrochloric acid concentration is the cornerstone in guaranteeing expected reaction rate and direction, in which even minor deviations in concentration make a big difference in reaction.
For example, concentrated hydrochloric acid lead to overly intense reaction with numerous side reactions, introducing impurities and lowering product quality. On the contrary, insufficient reaction incurred by low concentration results in resource wastage and cost increasing for low conversion rates of raw material. Furthermore, low conversion rates turns down the efficacy of drugs, posing potential safety risks to patient health.
Challenges in Concentration Measuring of Hydrochloric Acid Feed
Traditional devices like glass float-type densitometers are often worn and corroded after prolonged use. Then measurement of accuracy and stability will be affected, resulting in great deviations between the collected concentration and the actual value. Such glass float-type densitometers fail to monitor concentration in real-time for their instabilities.
Complex factors pose challenges for concentration measuring of hydrochloric acid. For instance, volatile acids and bases may adhere to sensors, which interfere to the accuracy of hydrochloric acid concentration. Besides, strong electromagnetic interference to measuring instruments which work on the principle of electronic sensing technology. Output readings then fluctuate abnormal; even data loss will come across for technological interference.
Manual sampling and measurement points influence accuracies, too. Overall concentration of the hydrochloric acid feed should be measured in a more reasonable way. Local sampling of hydrochloric acid feed is not accurate to reflect the overall concentration in case of unstable flow rates and insufficient mixing of raw materials.
Advantages of Real-Time Concentration Measurements
The density meter online makes real-time measurement of hydrochloric acid possible, providing information about the concentration or density in real time. Sensors work on the principle of ultrasonic velocity measurement, without interference from demanding measurement conditions.
A sound pulse is sent through the liquid and the time it takes to reach the receiver is measured to calculate the speed of sound. The speed of sound could be calculated easily since the distance from transmitter to receiver is constant by design.
Real-time monitoring of the online densitometer makes the device a critical hub to guarantee the continuity and stability of production. Data on concentration could be updated and transmitted to the control system instantly. The intelligent control system will respond immediately to adjust the flow rate at inlet feed if the concentration deviates from the preset value.
