operating a cooling tower water system. In spite of these concerns, treatment and control of cooling tower water is commonly neglected, which is then responsible for substantial problems due to downtime, equipment damage, loss of process control, high water use, environmental violations, safety hazards, and increased energy usage.
Description: Packed Tower Gas Scrubbers are low-energy gas scrubbers. They are used for gas absorption, cooling, and recovery.Because of their high scrubbing efficiency and low power consumption, they are used in many industries for a broad range of applications.

Cooling Tower Operation and Types. Cooling towers are specialized heat exchangers that reduce the temperature of water by bringing it in contact with air. Water, which has been heated by an industrial process, is pumped to the cooling tower through pipes.
Cooling Towers  ... Dr Eduardo Calixto, in Gas and Oil Reliability Engineering (Second Edition), 2016. Water Cooling Subsystem Modeling. ... In a recent process, iron electrodes are used for reduction of chromate and can be used for the removal of hexavalent chromium.
In reality, cooling towers do not keep things cool as much as they reject heat, which they do by transferring heat from the water source to the atmosphere through the process of evaporation (latent) and sensible heat transfer, thereby reducing the water temperature.
Freezing & Cooling Many industrial production processes require rapid cooling and freezing capabilities. Liquid nitrogen (LIN) and carbon dioxide (CO 2 ) are extremely effective cooling agents due to the low boiling point of LIN (-196°C) and the low sublimation point of CO 2 (-78.5°C).
For industrial companies using a cooling tower for its facility, some type of cooling tower water treatment system is usually necessary to ensure an efficient process and long equipment service life.
Cooling towers. Cooling towers remove heat from process water by evaporation and latent heat transfer between hot water and air. The two types of towers are counterflow and crossflow. · In counterflow cooling, hot process water is pumped to the uppermost plenum and allowed to fall through the tower.
Corex Process in Iron Making. ... (850°C) through the addition of cooling gas. A major part of this gas is subsequently fed to the reduction shaft. The excess gas is used to control the plant pressure. This excess gas and the reduction shaft top gas are mixed prior to the take over point and is termed as COREX export gas. ... Sponge iron ...
IRON SPONGE gas purification is a process originally developed for cleaning coke oven gas to remove hydrogen sulfide (H2S) resulting from the sulfur in the coal. This product called IRON SPONGE is hydrated iron oxide on a carrier of wood shavings and chips. IRON SPONGE is most frequently supplied with 15 pounds of iron oxide per bushel of product.

Basic Chemistry of Chlorination Chlorine (Cl 2) is a gas, heavier than air, toxic, non-flammable and an economically available oxidizing agent that provides properties desirable in disinfection usage. Chlorine is available in one of three forms: sodium hypochlorite, calcium hypochlorite and liquid chlorine. 1.
Instead, the tower containing the spent iron sponge is taken out of service, and the standby tower is placed in service. The spent iron sponge is moistened with water, removed, and disposed of at an approved disposal site, and the tower is filled with a new charge of iron sponge.
Generation of Energy Conservation Measures for Sponge Iron Plants Anil Kumar Prasad, Vivek Kumar and Shabina Khanam, Member, IAENG Abstract - During the operation, a tremendous amount of heat is generated in the coal based sponge iron plant and a significant part of this heat associated with the waste gas, remains unutilized.
This gas not only replaces the coal fines but also results in overall saving of roughly 20% of total coal used. This technology have given new life to Sponge Iron plant as this process is now viable with roughly 20MT of coal saving for 100 TPD Plant in a day. This CASE gasifier is totally PLC controlled automatic machine.
Cooling towers are hidden profits for energy conservation and dollar savings when properly engineered and maintained. The limiting factor of production is the quality and quantity of cold water ...
Recovery and utilization of waste heat in a coal based sponge iron process Vivek ... gas throughout the process is generated by an induced draft (ID) fan located near the chimney. The operating data of the process, taken from a typical plant of 100tpd, is shown in Fig. 1.

· In this modification cooling gas is pumped by a pump 74 through pipes 76 and 78 to the bottom of cooling zone 14 and flows upwardly through the descending body of particulate sponge iron to cool it. The recycled gas, withdrawn from the top of cooling zone 14 through a pipe 80, is cooled in a cooler 82 and returned through pipe 84 to the suction ...
Coal-based sponge iron process The process of the direct reduction of haematite in a rotary kiln is schematically described in the Fig.21 tph Spent lime=0.000 TPA module of DR plant. 1. The cooler discharge is then separated into sponge iron.166 tph Char= 0.
In a process for the direct reduction of metal oxide to iron sponge by means of reducing gases containing hydrogen gas in a reduction apparatus in which at least a portion of the water vapor formed in the reduction process and contained in the exhaust gas is separated as condensate by means of cooling …
Evaporative Cooling Towers are installed mainly in the cement & sponge iron industry. The essential components of an evaporative cooling tower are : The gas inlet cone with accessories for gas distribution devices. The cylindrical cooling tower casing in which the exhaust gases are cooled and conditioned by evaporation of water.
