Steam - Desuperheating and Attemperation

electric power generation plant
Steam is a motive force used to generate electric power
Industrial operations of many types utilize steam as a heat or power source, plus there is electric power generation. Steam is an important sort of "back office" component of the lives of many dwellers in modern economies.
What is steam?
Sorry, but we need to get everybody on the same page here. Steam is water vapor, produced by the application of heat to water. In order for steam to do work and serve as a useful energy source, it must be under pressure. There can be applications that employ steam at atmospheric pressure, but most are pressurized.

The heat goes on, the water boils, steam is produced and flows through the piping system to where it is used. Sounds simple, sounds easy. It is not. There are intricacies of designing and operating a steam system that determine its raw performance, as well as how efficiently it uses the fuel or other heat source employed to boil water. Steam utilization equipment is also carefully designed to provide its rated performance when supplied with steam of a given condition.

Steam at any given pressure has a saturation temperature, the temperature at which the vaporized water content of the steam is at its maximum level. Heat steam above its saturation temperature and you have superheated steam. Cool it below the saturation temperature and vapor will start to condense. The way in which the steam is to be used determines whether, and how much, superheat is desirable or necessary.
  • Turbine operations benefit from properly superheated steam because it avoids exposure of the turbine to liquid water droplets, generally a source of surface erosion and other accelerated wear.
  • Heat exchanger performance is based upon certain inlet conditions, one of which is the degree of superheat.
  • Maintaining sufficient superheat throughout a continuously operating steam system minimizes the need for, and size of, a condensate return system
Processes are designed to deliver a predictable output when provided with known inputs. In the case of steam, the temperature of the steam may be an input requiring control. This brings us to attemperation, which in the case of steam most often refers to lowering the temperature of a steam supply. Attemperation and desuperheating (reducing the degree of superheat) are accomplished in a similar fashion, but with differing objectives. Attemperation involves simply controlling the temperature of the steam, without any direct regard for the level of superheat. Desuperheating, as a control operation, is not directly related to the temperature of the steam, just the degree by which it exceeds the saturation temperature at the current condition. For attemperation, steam temperature measurement is all that is needed. For desuperheating, pressure and temperature measurements are needed. Decreasing the temperature of superheated steam will naturally reduce the amount of superheat.

Some process requirements may focus on temperature of the delivered steam, without regard to superheat level. Others will rely on a specified level of superheat. The application scenarios are vast, with equipment available to accomplish whatever is needed.

Either operation can be accomplished with a specialized heat exchanger or other device that extracts heat from the steam. Another option relies on the addition of atomized water to the flowing steam to manage temperature or superheat level. Share your steam system challenges with steam system experts, leveraging your own knowledge and experience with their product application expertise to develop an effective solution.

Modular Refrigerated Air Dryer For Industrial Compressed Air

air dryer combines backup capacity with demand based usage.

Compressed air is a common, and in some cases lifeblood, utility and source of power in industrial plants and operations. It is well established that limiting the moisture in compressed air is preferred. Modern operations increasingly demand drier compressed air supply containing fewer contaminants. Some of the potentially damaging effects of moisture in compressed air systems include:
  • In air operated instruments, corrosion, leading to incorrect readings and false responses by plant operators.
  • In pneumatic controls, clogging of orifices and malfunction of controls due to rust and scale can result in additional maintenance and repair, even process malfunction or shutdown.
  • Spray-on coating operations are impacted by moisture level, which can affect color, finish, and adherence of the applied material.
  • In industrial production equipment, moving parts can experience rust and premature wear due to the washing away of lubrication by excessive moisture in compressed air.
When ambient air is compressed, its temperature increases, but also does the ratio of water per unit of air volume. This results in a compressed air supply with what may be an unacceptably high dew point. Dew point is the temperature at which air is saturated, and cooling air below its dew point will result in the formation of condensate (liquid water). As compressed air is consumed by usage equipment, the air pressure drops, along with the temperature. These condition changes, and others, can result in condensate formation in the compressed air system and connected equipment. This is generally considered a negative development, as the presence of excessive moisture can lead to line freezing, corrosion, excessive equipment wear, and malfunction.

For many industrial applications, removing moisture from compressed air can be accomplished on a continuous basis utilizing a properly configured mechanically refrigerated air dryer. SPX Flow Techonology's Pneumatic Products brand of refrigerated air dryers applies best in class refrigeration technology to deliver substantial energy savings to the process. The ESM product line features:
  • Measurable energy savings.
  • Rapid return on investment
