The superiority of V-cone flow meter to measure urea hydrolysis vapor

Project Overview

In today's industrial production field that pursues high efficiency and environmental protection, the optimization of every detail may become the key to promoting industry progress. Especially in chemical processing and environmental protection technology, accurate measurement and control of gas flow is particularly important. The urea hydrolysis process is a basic step in nitrogen fertilizer production, denitrification technology and many chemical applications. The accurate measurement of ammonia and carbon dioxide produced is not only related to production efficiency, but also a key link in achieving energy conservation and emission reduction goals. In this context, V-cone flowmeter has become an ideal choice for this application scenario with its unique advantages.

The importance of urea hydrolysis

Urea hydrolysis reaction, simply put, is the decomposition of urea (CO(NH₂)₂) into ammonia (NH₃) and carbon dioxide under specific conditions (CO₂), this process is widely used in fertilizer manufacturing, flue gas denitration and some specific chemical synthesis processes. Accurately measuring the flow of ammonia and carbon dioxide released during this process is of great significance for controlling reaction efficiency, optimizing raw material utilization, and reducing energy consumption and environmental emissions.

The precision advantage of V-cone flowmeter

V-cone flowmeter, as a flow measurement device based on the principle of differential pressure, sets a cone with a downward tip in the fluid. To change the fluid flow state, thereby generating a stable differential pressure signal, and thus accurately measuring the flow rate. Compared with traditional flow meters, V-cone flow meters show the following significant advantages when measuring ammonia and carbon dioxide, the products of urea hydrolysis:

1. Wide range ratio: V-cone flowmeter can cover a wider flow range, from as low as several cubic meters per hourIt can maintain a high degree of measurement accuracy up to thousands of cubic meters per hour, which is especially suitable for the characteristics of large flow changes during the urea hydrolysis reaction.

   

2. Low pressure loss: The unique tapered design reduces the pressure loss when the fluid passes through, helping to reduce operating costs, especially in processes that require a large amount of gas circulation. This is particularly important.

3. Self-cleaning characteristics: Although ammonia and carbon dioxide are common industrial gases, they may carry particles or condense under certain conditions. The self-cleaning ability of the V-cone flow meter It can effectively avoid clogging problems and ensure long-term stable operation.

4. Convenient installation and simple maintenance: V-cone flowmeters have lower requirements on straight pipe sections and are more flexible and easier to install. And because of their sturdy and durable design, daily maintenance costs are greatly reduced. .
