Desalination using spray tower and vapour compression refrigeration system
A desalination system using a spray tower and Vapour Compression Refrigeration (VCR) system is proposed for obtaining fresh water from brackish water. In the spray tower, simultaneous heat and mass transfer take place between the brackish water and air, which results in the evaporation of the brackish water and humidification of the air. Fresh water is obtained from the humidified air by ...

Stochastic modeling approaches based on neural network and linear–nonlinear regression techniques for the determination of single droplet collection efficiency of countercurrent spray towers
This paper presents a new mathematical model and a two-layer neural network approach to predict the single droplet collection efficiency (SDCE), η d, of countercurrent spray towers. SDCE values were calculated using MATLAB® algorithm for 205 different artificial scenarios given in a large range of operating conditions. Theoretical results were compared with outputs obtained from a two-layer ...

Mass flow measurement with SolidFlow 2.0 - Case Study
Application In an opencast mine, brown coal with a very high content of wax is mined. From this coal, raw montan wax is obtained in different process steps. Therefore, the coal is crushed, dried and impinged with an environmentally friendly solvent to separate the wax from the coal. The acquired montan wax is transported into an evaporation system, where it evaporizes in several stages. After ...

What is a spray tower?
Spray tower, also known as scrubber, wet scrubber, is waste gas treatment equipment. The exhaust gas is fully contacted with the liquid, and the concentration of the waste gas is reduced by using its solubility in water or chemical reaction, so as to become a clean gas that meets the national emission standards. It is mainly used to treat inorganic waste gas, such as sulfuric acid mist, hydrogen ...

CFD Analysis of Gas Cooling
In many industrial processes, hot gas is cooled down due to the evaporation (boiling) of sprayed droplets. The effects of two different atomizer types, inner mixing air atomizing nozzles and flow back nozzles, on the cooling behavior inside a spray tower for a typical flue gas are discussed. The heat and mass transfer is computed using computational fluid dynamics (CFD). The interaction between ...

Hundreds of Options Facing Power Plants Purchasing New or Upgrading
The wet calcium (lime and limestone) process is only one option for removing SO2. Dry systems, ammonium sulfate, seawater, amine and other processes are also alternatives. Assuming that the purchaser has decided to purchase a new or upgrade an existing wet calcium FGD system, he must then make hundreds of decisions about processes and components. These systems represent up to 15 percent of the ...

Numerical Simulation of Spray Pattern in a Liquid Flashing Column
Spray columns and towers are fundamental in many industrial applications. Understanding the spray pattern in these dynamic environments is very important in the design of an overall spray system solution. Traditional laboratory physical experiments can be time-consuming, expensive, and sometimes impossible to complete. Computational fluid dynamics (CFD) modeling can be used effectively in this ...

Industrial waste gas treatment system design process
Most industrial manufacturing companies now install environmental protection equipment, and they are more concerned about whether they can meet the standards after installation. There are three points to achieve the standards: 1. Does the manufacturer have this technical strength? 2. Is the product selection correct? 3. Is there any experience in waste gas treatment engineering, or do not ...

Wet Scrubbers for Air Pollution Control
A wet scrubber, also known as a "wet scrubber system," is a device used to remove pollutants from industrial and commercial exhaust streams. It is an air pollution control technology that uses a liquid, usually water, to capture and remove pollutants from an airflow. Wet scrubbers are widely used in many industries including power plants, steel mills, chemical plants and refineries. The basic ...

Why we need wet scrubbers for industrial waste gas?
As a commonly used industrial waste gas treatment equipment, the wet scrubber has the advantages of high removal rate and wide application range. In industrial production, various types of waste gas will be produced, and corrosive waste gas also accounts for a large proportion, and these waste gases need to be purified before they can be discharged. There are many purification treatment ...

Wet scrubbers monitor flue gas emissions in a combustion system
Wet scrubbers are considered to be air treatment devices to take away gaseous particulate pollutants (NOx, SOx or other gases produced by combustion systems) that negatively affect the environment. According to air pollution control measures, it is required to take away these particulates in order to protect the receptors from the serious impacts of these gases on the health of humans and ...

Washing tower waste gas treatment equipment
Working principle of exhaust gas scrubber The scrubbing tower is also called spray tower and wet scrubber. It consists of four parts: tower body, trays, reboiler and condenser. The scrubber is a device for rough separation, so the number of trays is generally small, usually not more than ten stages. The scrubber is suitable for the separation of mixed gas containing a small amount of dust, the ...
