Fractionation is a separation process in which a certain quantity of a mixture (of gasses, solids, liquids, enzymes, or isotopes, or a suspension) is divided during a phase transition, into a number of smaller quantities in which the composition varies according to a gradient.
The design of fractionation columns is normally made in two steps; a process design, followed by a mechanical design. The purpose of the process design is to calculate the number of required theoretical stages and stream flows including the reflux ratio, heat reflux, and other heat duties.
This process is the origin of the name fractional distillation or fractionation. Distillation is one of the most common and energy-intensive separation processes. Effectiveness of separation is dependent upon the height and diameter of the column, the ratio of the column's height to diameter, and the material that comprises the distillation ...
The fractionation train typically uses a cryogenic low temperature distillation process involving expansion of the recovered NGL through a turbo-expander followed by distillation in a demethanizing fractionating column. [30] [31] Some gas processing plants use lean oil absorption process [27] rather than the cryogenic turbo-expander process.
The frozen solid phase subsequently has a different composition than the remaining liquid. This is the fundamental physical principle behind the melt fractionating process and quite comparable to distillation, which operates between a liquid and the gas phase. The crystals will grow on a cooled surface or alternatively as a suspension in the ...
Transporting and storing natural gas, natural gas liquids (NGL) fractionation. Import and export terminalling. Offshore production platform services. The company has four reportable business segments:
A nitrogen generator Bottle of 4Å molecular sieves. Pressure swing adsorption provides separation of oxygen or nitrogen from air without liquefaction. The process operates around ambient temperature; a zeolite (molecular sponge) is exposed to high pressure air, then the air is released and an adsorbed film of the desired gas is released.
A pair of siblings have reignited a debate over cake — specifically, what it means to be a chocolate cake. In December, Gia Cooper posted a video to TikTok, and later to Instagram, where the ...
