Acid gas treating, also known as gas sweetening and sour gas treating, refers to a group of processes that use various aqueous solvents such as Amines, Hot Potassium Carbonate, Sodium Hydroxide etc, to remove hydrogen sulfide (high toxicity) and carbon dioxide (lack of heating value) from gases. It is a very common unit process used in Gas Processing plant, Refineries, petrochemical plants, Coal Fired Power Plant and other industries. Principle Separation Technologies are listed below: Solvent Separation Adsorption Membrane Separation Cryogenic Distillation Solvent Separation: Figure below shows a general schematic of the CO2 removal using a sorbent.   Acid Gas Removal using amine treating Solvent separation process uses liquid absorbent or solid sorbent. It consists two steps - the absorption step and the regeneration step. In the contactor vessel, the CO2 - containing gas is brought into contact with regenerated solvent which captures the CO2. The rich solvent, loaded with C...

There are  many factors that affect steam generating system  in the energy industry, and multiple pros and cons in selecting a right steam trap for your application, the following are advantages vs. disadvantages of each type of steam trap to consider when selecting one for your project. Advantages Disadvantages Disc Steam Traps • Failure mode. gradually, predictably open over time. • Simple construction. • Small size and light weight. • Can be mounted in any position. • Rugged. withstands water hammer. • Self draining, not damaged by freezing. • Function not impaired by superheat. • Versatile, suitable for wide pressure range. • Condensate discharge temperature closely follows the saturation curve. • Performance is easily checked in field. • Marginal air handling capability. • Excessive backpressure in return systems can prevent trap from closing. • Life is reduced significantly as pressures move above 300 psi. • High discharge noise level. • Dirt particles can increase cy...
