» Processing Natural Gas NaturalGas.org

In this process, a liquid desiccant dehydrator serves to absorb water vapor from the gas stream. Glycol, the principal agent in this process, has a chemical affinity for water. This means that, when in contact with a stream of natural gas that contains water, glycol will serve to 'steal' the water …

Correct procedure for water filling in boiler - ASKPOWERPLANT

The make-up water is usually natural water either in its raw state, or treated by some process before use. Feed-water compositiontherefore depends on the quality of the make-up water and the amount of condensate returned to the boiler. The steam, which escapes from the boiler, frequently contains liquid droplets and gases.

How to Destroy a Boiler -- Part 3

The feedwater (make-up water) from outside needs to be treated for the reduction or removal of impurities by first filtration, and then followed by softening, evaporation, deariation, ion exchange etc. Internal treatment is also required for the conditioning of impurities within the boiler system, to control corrosion, as reactions occur in the boiler itself and the steam pipelines.

The ideal regenerative Rankine cycle

A considerable percentage of the total energy input is used to heat the high pressure water from T 2 to its saturation (point a). Figure.2. Rankine cycle. To reduce this energy, the water could be preheated before it enters the boiler by intercepting some of the stream as it expands in the turbine and mixing it with the water as it exits the

Economizer - an overview | ScienceDirect Topics

Colin French CEng, FlnstE, FBIMgt, in Plant Engineer's Reference Book (Second Edition), 2002. 31.1 Introduction. Economizers for boilers have been available for nearly 150 years, almost as long as boilers themselves. For modern shell boilers, high efficiencies have made it increasingly difficult to justify the use of an economizer, the final decision being based in terms of payback period

Heating Systems Flow Rates - Engineering ToolBox

The volumetric flow rate in a heating system can be expressed as. q = h / (cp ρ dt) (1) where. q = volumetric flow rate (m3/s) h = heat flow rate (kJ/s, kW) cp = specific heat (kJ/kgoC) ρ = density (kg/m3) dt = temperature difference (oC) This generic equation can be modified for the actual units - SI or imperial - and the liquids in use.
