The treated gas is introduced from the gas inlet at the bottom of the main body, passes through the filling layer of HiLex, and is discharged from the gas outlet at the top. Meanwhile, the absorbent liquid is sprayed from the top of the filling layer and comes into countercurrent contact with the treated gas. During this process, the target substances in the gas diffuse and dissolve into the liquid phase. 【Features】 ■ Efficient removal: High-performance packing material HiLex selected according to design conditions ■ Low pressure loss, low power costs: ■ Compact design: ■ Compatible with various applications: Designed for use not only in absorption towers but also in dispersion towers, dehumidification towers, recovery towers, mist and dust removal towers, and gas cooling towers. *For more details, please contact us or download the catalog to view.

[Case Study] - Industry of delivery destination: Chemical - Designed and installed equipment: Pre-cooling tower + Venturi + demister tower + two packed towers - Designed removal rates: - Acetic acid gas: 25,000 ppm to below 1 ppm - Fume-like sublimates: 5 g/Nm³ to below 0.1 g/Nm³ - Packing material: Hyrex 200PP 2000H x 2 - Material: Main body made of SUS304 and corrosion-resistant FRP *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the delivery of a pre-cooling tower and a Venturi scrubber conducted by E-Techno. The processing gas volume is 4568 Nm³/h, with a temperature of 60.4°C, targeting the removal of white pigment dust, reducing particulate matter from 0.2 g/Nm³ to below 0.01 g/Nm³. Gas-liquid contact is achieved using water (circulation + supply) for cooling and removal of hydrogen chloride. Particles in the circulating liquid are precipitated and collected. [Case Study] - Industry of the delivery destination: Chemical - Equipment designed and installed: Pre-cooling tower + Venturi scrubber - Processing gas volume: 4568 Nm³/h - Target removal substance: White pigment dust - Designed removal rate: Particulate matter from 0.2 g/Nm³ to below 0.01 g/Nm³ - Material: Both the main body and the blower are made of SUS304 *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the two-stage Mist Eliminator delivered by E-Techno. The target substance for removal is salt dust, with a processing gas volume of 290 m³/min and a temperature of 20°C. The gas-liquid contact for removal is achieved using water (circulation + replenishment). The designed removal rate is over 99% for particles larger than 20μm. 【Case Study】 ■ Industry of Delivery: Food ■ Designed and Installed Equipment: Two-stage Mist Eliminator ■ Processing Gas Volume: 290 m³/min ■ Target Substance for Removal: Salt Dust ■ Designed Removal Rate: Over 99% for particles larger than 20μm ■ Gas-Liquid Contact: Removal using water (circulation + replenishment) ■ Material: The main body is corrosion-resistant FRP *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the Mist Eliminator two-stage system implemented by E-Techno. The processing gas volume is 1160 m³/min, with a temperature of 90°C (starting at 165°C), and the target substance for removal is sodium chloride dust (dust amount of 1200 kg/h) with a concentration of 17.24 g/m³. The gas-liquid contact is achieved using sodium chloride brine (circulation + replenishment) for removal, with a salt recovery concentration of 200 to 260 g/L, and the designed removal rate is over 99% for particles larger than 20 μm.

This document is a collection of case studies on exhaust gas treatment, mist separation, and dust removal devices that are highly efficient, have low pressure loss, and low running costs. We introduce a variety of items, including "E-Techno Co., Ltd.'s lineup of environmental equipment," "examples of local exhaust systems," "characteristics of the E-730 series," and "delivery photos." Additionally, we also include "selection materials for dust, fume, and mist removal devices" and "site photos of venturi scrubbers." We encourage you to read through it.
