"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]

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.

"An oil refinery or petroleum refinery is an industrial process plant where crude oil is processed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene and liquefied petroleum gas. Oil refineries are typically large, sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids between large chemical processing units. In many ways, oil refineries use much of the technology of, and can be thought of, as types of chemical plants. The crude oil feedstock has typically been processed by an oil production plant. There is usually an oil depot (tank farm) at or near an oil refinery for the storage of incoming crude oil feedstock as well as bulk liquid products.
An oil refinery is considered an essential part of the midstream side of the petroleum industry." [en.wikipedia.org/ wiki/ Oil_ refinery]

"Ornamental plants are plants that are grown for decorative purposes in gardens and landscape design projects, as houseplants, for cut flowers and specimen display. The cultivation of these, called floriculture, forms a major branch of horticulture. ...
Similarly certain trees may be called ornamental trees. This term is used when they are used as part of a garden or landscape setting, for instance for their flowers, their texture, form and shape, and other aesthetic characteristics. In some countries trees in 'utilitarian' landscape use such as screening, and roadside plantings are called amenity trees." [Ornamental plant. Wikipedia]
