Game theory approach for the design of an optimal air pollution control system for thermal power plants
A procedure, based on the concept of game theory, for the optimum design of an air pollution control system in thermal power plants is described. The problem is formulated as a four-criteria optimisation problem, with the cost of the electrostatic precipitator, the cost of the stack, the maximum ground-level concentration of particulate matter and the maximum ground-level concentration of sulfur ...

Industrial Air pollution control and Monitoring - Case Study
Industries emit various pollutants like Carbon Monoxide, Carbon Dioxide, Sulphur Oxide etc which are harmful for plant and animal life. Especially in cities where the pollution is at its peak, there needs to be continuous monitoring of pollution statistics to ensure that the pollution is within safe limits. Prkruti provides real time data of the pollution statistics from various locations within ...

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 ...

PADEP Transition from CAIR to CSAPR
As of January 1, 2015 the U.S. Environmental Protection Agency (U.S. EPA) has been implementing the Cross-State Air Pollution Rule (CSAPR) through a Federal Implementation Plan (FIP) that primarily impacts electric generating units (EGUs). This article reviews the transition of the Clear Air Interstate Rule and nitrogen oxide (NO2), sulfur dioxide (SO2) allowances to CSAPR allowances and ...

Local emissions trading in developing countries as a transitional strategy toward international greenhouse gas trading: a Beijing example
As is the case in most developing countries, China relies on command-and-control regulation to control air pollution. While it has instituted a modest air pollution levy system in the past 20 years for emissions in excess of standards, the effect on emission levels has been minimal. This paper focuses on how to use emissions trading as a policy instrument to achieve cost-effective reductions in ...

Strategy for Complying with Air Pollution Control Regulations in the Chemical Industry
Untitled Document The Clean Air Act (CAA) was originally passed by the United States Congress in 1970 and subsequently revised in 1977 for the purpose of protecting human health and the environment. In 1990, then-President George Bush signed the Clean Air Act Amendments. The far-reaching impacts of the 1990 amendments added significantly to the regulatory challenges ...

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 ...

Container and Flat Glass Manufacturing
Glass Melting Furnaces. Applications where several pieces of conventional equipment struggle to attain only marginal efficiency provides an opportunity for the Cloud Chamber Scrubber (CCS) to showcase its unique capabilities as a multi-pollutant device. Container / float glass manufacturing is a typical example. Following other successful applications in the glass industry, a pilot study to ...

Tri-Mer’s UltraCat glass furnace emissions filters deliver significant advantages in terms of sorbent use, maintenance requirements, and redundancy - Case study
UltraCat Catalytic Filter systems require much less sorbent to reach a given SO2 removal than ESP. This is because the sorbent accumulates on the filter surface, creating a filter cake. All the gas must pass through this cake, adding exposure and time for sorbent chemistry to occur. This is true for any sorbent, SBC or hydrated lime. Another advantage is the built-in redundancy inherent in ...

What is a wet scrubber and how it works?
A wet scrubber is a mechanical system that removes contaminants from a gas stream by contacting it with a scrubbing liquid, most commonly water. Wet scrubbers are often the only air pollution control devices that can remove both particulates and gases/vapors. They are very efficient at capturing the smallest dust particles and can trap them in droplets, eliminating over 99% of airborne particles. ...
