Optimization of a Kraft Pulp Mill Chlorine Dioxide (ClO2) Scrubber - With Q-PAC Repack Power Costs are Reduced by Over $80,000 per Year and Emissions are Non-Detectable
An existing ClO2 (chlorine dioxide) scrubber tower at a pulp mill was repacked during a planned maintenance shut down. As the result of replacing 3" Kynar and 2" CPVC Norton Super Interlox saddles with Q-PAC from Lantec Products, the scrubber tower is now operating at a greatly reduced pressure drop compared to when the tower was packed with saddles. The reduced pressure drop has ...

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 ...

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 ...

Introduction of scrubber + activated carbon adsorption exhaust gas purification device
Washing tower + activated carbon adsorption exhaust gas purification device It is suitable for the treatment of waste gas with low concentration and non-single components. The granular dust, smoke and grease can be removed through the water shower tower. The treated waste gas is absorbed by the activated carbon adsorption tower. The function of the water shower tower is to purify the waste gas ...

To MACT and Beyond case study
In the 1970s, FMC Corp., a chemical manufacturer headquartered in Philadelphia, began operating a high-efficiency thermal destruction facility to dispose of hazardous liquid wastes at its Baltimore pesticide manufacturing plant. The facility used a thermal oxidizer with a rapid quencher and packed tower scrubber to remove air pollution emissions. The system was upgraded in the early ’80s ...

What waste gas can the wet scrubber treat?
The packing layer in the wet scrubber serves as a mass transfer device for the contact components between the gas and liquid phases. The bottom of the packing tower is equipped with packing support plates, and the packing is placed on the support plates in a random pile. A packing pressure plate is installed above the packing to prevent it from being blown by the rising airflow. The spray liquid ...

Odor Control H 2 S / Sewer Gas Wet Scrubbing Explained
H2S / Sewer Gas / Rotten Egg Smell Control Hydrogen Sulfide, chemical formula H2S. also commonly referred to as 'sewer gas' is frequently a nuisance problem at waste water treatment facilities - and a source of complaints from neighbors of such facilities. Additionally, H2S not only stinks, at high concentrations it incapacitates, blinds and eventually will kill if allowed to concentrate ...

Common Treatment Technologies for Nonhalogenated VOCs
Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

Radon Air Stripping of Well Water
Radon is Frequently Found in Ground Water Radon, symbol Rn, atomic number 86, is a colorless, odorless gas at ambient conditions. It is the heaviest element of the Noble Gas family. As such it is extremely stable and unreactive chemically. But it also is highly radioactive. Its half-life is only 3.8 days. Both Thorium, symbol Th, atomic number 90 and Uranium, symbol U, atomic number 92, have no ...

Food Processing: Odor Control in Edible Oil Processing
Abstract: The problems with odor around a typical edible oil deodorizer are discussed in detail, and a three-step solution to eliminate these problems is presented. The three steps are a distillate recovery system which recovers most of the fatty acid in the deodorizer vapor discharge as a valuable byproduct, a closed loop barometric cooling water system which keeps the fatladen hotwell water out ...

Introduction to the internal structure of the wet scrubber, spray device and defogging device
The organic waste gas is introduced into the scrubbing tower through the air pipe, and passes through the packing layer. The waste gas and the sodium hydroxide absorption liquid undergo gas-liquid two-phase full contact, absorption and neutralization reaction. Into the atmosphere. The absorption liquid is sprayed down at the top of the tower after being pressurized by a water pump at the bottom ...

Chemical Industry: Compliance problems solved by Ethylene Oxide Scrubber at Specialty Gas Plant Chemical Industry The ethylene glycol produced in the ethylene oxide scrubbing operation acts as an antifreeze to allow year-round operation - Case Study
Problem: A specialty gas producer was confronted with an EPA compliance problem in dealing with ethylene oxide (EtO). The chemical had been added to the toxicity lists of the U.S. EPA and the Occupational Safety and Health Administration (OSHA). Effective August 21, 1984, the OSHA standard for EtO limited exposure to a 1 ppm, eight-hour time weighted average. Ethylene oxide is used to sterilize ...
