µg/m3. HelpCenter Definition. The concentration of an air pollutant (eg. ozone) is given in micrograms (one-millionth of a gram) per cubic meter air or µg/m3.
Thermal conductivity of some selected gases, insulation products, aluminum, asphalt, brass, copper, steel and other common materials. Thermal conductivity is a material property that describes ability to conduct heat. Thermal conductivity can be defined as. "the quantity of heat transmitted through a unit thickness of a material - in a ...
A de-asphalter is a unit in a crude oil refinery or bitumen upgrader that separates asphalt from crude oil or bitumen.. The de-asphalter unit is usually placed after the vacuum distillation tower. It is usually a solvent de-asphalter unit, SDA. The SDA separates the asphalt from the feedstock because light hydrocarbons will dissolve aliphatic compounds but not asphaltenes.
Environmental Impact Assessment - EIA . The EIA Directive (85/337/EEC) is in force since 1985 and applies to a wide range of defined public and private projects, which are defined in Annexes I and II:. Mandatory EIA: all projects listed in Annex I are considered as having significant effects on the environment and require an EIA ( long-distance railway lines, motorways and express roads ...

Carbon uses semantic versioning. We use our version number to communicate how Carbon changes from the last version. Carbon version numbers have the form When upgrading to a new version, if: Just the patch number has changed ( -> ) then we've only fixed bugs in a 100% backwards-compatible way.

Specific heat (C) is the amount of heat required to change the temperature of a mass unit of a substance by one degree.. Isobaric specific heat (C p) is used for air in a constant pressure (ΔP = 0) system.; Isochoric specific heat (C v) is used for air in a constant-volume, (= isovolumetric or isometric) closed system.; Note! At normal atmospheric pressure of bar - the specific heat of ...

Net Zero by 2050. Submit. Download data as CSV. All Net Zero Tracker data will be updated to reflect an Oxford-ECIU analysis that is pending journal publication, the high-level results of which can be read here. Later in 2021, our Tracker will enjoy a major upgrade so that we can track the *quality* as well as the quantity of net zero targets ...
The IPCC Working Group I (WGI) examines the physical science underpinning past, present, and future climate change. Scientists all over the world regularly assess the rich body of scientific literature, contributing to an ever-strengthening understanding of how the climate system works, and how it is changing in response to human activity.
Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines to remove hydrogen sulfide and carbon dioxide 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 …
Amine gas treating, also known as amine scrubbing, 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 (H 2 S) and carbon dioxide (CO 2) from gases. It is a common unit process used in refineries, and is also used in petrochemical plants, natural gas processing ...
