Amine treating unit schematic diagram

This process flow diagram (PFD) example shows an amine treating system for the removal of gaseous hydrogen sulfide from gas streams. It is used in oil refineries and chemical plants.

"Amine gas treating, also known as gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H2S) and carbon dioxide (CO2) from gases. It is a common unit process used in refineries, and is also used in petrochemical plants, natural gas processing plants and other industries.
Processes within oil refineries or chemical processing plants that remove hydrogen sulfide are referred to as "sweetening" processes because the odor of the processed products is improved by the absence of hydrogen sulfide. An alternative to the use of amines involves membrane technology. Membranes are attractive since no reagents are consumed.
Many different amines are used in gas treating:
Diethanolamine (DEA),
Monoethanolamine (MEA),
Methyldiethanolamine (MDEA),
Diisopropanolamine (DIPA),
Aminoethoxyethanol (Diglycolamine) (DGA).
The most commonly used amines in industrial plants are the alkanolamines DEA, MEA, and MDEA. These amines are also used in many oil refineries to remove sour gases from liquid hydrocarbons such as liquified petroleum gas (LPG)." [Amine gas treating. Wikipedia]

Bubble diagrams in Landscape Design with ConceptDraw DIAGRAM

Bubble Diagrams are the charts with a bubble presentation of data with obligatory consideration of bubble's sizes. They are analogs of Mind Maps and find their application at many fields, and even in landscape design. At this case the bubbles are applied to illustrate the arrangement of different areas of future landscape design, such as lawns, flowerbeds, playgrounds, pools, recreation areas, etc. Bubble Diagram helps to see instantly the whole project, it is easy for design and quite informative, in most cases it reflects all needed information. Often Bubble Diagram is used as a draft for the future landscape project, on the first stage of its design, and in case of approval of chosen design concept is created advanced detailed landscape plan with specification of plants and used materials. Creation of Bubble Diagrams for landscape in ConceptDraw DIAGRAM software is an easy task thanks to the Bubble Diagrams solution from "Diagrams" area. You can use the ready scanned location plan as the base or create it easy using the special ConceptDraw libraries and templates.

Jet fuel mercaptan oxidation treating - PFD

"Merox is an acronym for mercaptan oxidation. It is a proprietary catalytic chemical process developed by UOP used in oil refineries and natural gas processing plants to remove mercaptans from LPG, propane, butanes, light naphthas, kerosene and jet fuel by converting them to liquid hydrocarbon disulfides.
The Merox process requires an alkaline environment which, in some of the process versions, is provided by an aqueous solution of sodium hydroxide (NaOH), a strong base, commonly referred to as caustic. In other versions of the process, the alkalinity is provided by ammonia, which is a weak base.
The catalyst in some versions of the process is a water-soluble liquid. In other versions, the catalyst is impregnated onto charcoal granules.
Processes within oil refineries or natural gas processing plants that remove mercaptans and/ or hydrogen sulfide (H2S) are commonly referred to as sweetening processes because they results in products which no longer have the sour, foul odors of mercaptans and hydrogen sulfide. The liquid hydrocarbon disulfides may remain in the sweetened products, they may be used as part of the refinery or natural gas processing plant fuel, or they may be processed further.
The Merox process is usually more economical than using a catalytic hydrodesulfurization process for much the same purpose." [en.wikipedia.org/ wiki/ Merox]
