Blend time, sometimes termed mixing time, is the time to achieve a predefined level of homogeneity of a tracer in a mixing vessel. Blend time is an important parameter to evaluate the mixing efficiency of mixing devices. [1] In order to make this definition valid, the tracer should be in the same physical phase (e.g. liquid) as the bulk material.
Western Canadian Select (WCS) is a heavy sour blend of crude oil [1] that is one of North America's largest heavy crude oil streams [2] and, historically, its cheapest. [3] It was established in December 2004 as a new heavy oil stream by EnCana (now Cenovus), Canadian Natural Resources, Petro-Canada (now Suncor) and Talisman Energy (now Repsol Oil & Gas Canada). [4]
However, like methane, R-410A has a global warming potential (GWP) that is appreciably worse than CO 2 (GWP = 1) for the time it persists. R-410A is a mixture of 50% HFC-32 and 50% HFC-125. HFC-32 has a 4.9 year lifetime and a 100-year GWP of 675 and HFC-125 has a 29-year lifetime and a 100-year GWP of 3500.
Naphtha (/ ˈ n æ f θ ə /, recorded as less common or nonstandard [1] in all dictionaries: / ˈ n æ p θ ə /) is a flammable liquid hydrocarbon mixture.Generally, it is a fraction of crude oil, but it can also be produced from natural-gas condensates, petroleum distillates, and the fractional distillation of coal tar and peat.
Pyrolysis oil, sometimes also known as biocrude or bio-oil, is a synthetic fuel with few industrial application and under investigation as substitute for petroleum.It is obtained by heating dried biomass without oxygen in a reactor at a temperature of about 500 °C (900 °F) with subsequent cooling, separation from the aqueous phase and other processes.
Syngas, or synthesis gas, is a mixture of hydrogen and carbon monoxide, [1] in various ratios. The gas often contains some carbon dioxide and methane.It is principally used for producing ammonia or methanol.
Product sale value can change over time due to changing market conditions. Sufficiently large scale production sizes can influence market fundamentals and thus sale price. Operating costs are influenced by production rate and it is generally desirable to meet a specified operating capacity for the wash plant as well as to utilize contractual ...
Freeform surface modelling is a technique for engineering freeform surfaces with a CAD or CAID system.. The technology has encompassed two main fields. Either creating aesthetic surfaces (class A surfaces) that also perform a function; for example, car bodies and consumer product outer forms, or technical surfaces for components such as gas turbine blades and other fluid dynamic engineering ...
