Description: technologyComment of air separation, xenon krypton purification (CA-QC, RER, RoW): Kr-Xe-concentrate with 99.7% O2 is obtained from a side column of large air separation plants. Processes as purification and further distillation and the achieved yield may vary. Data represents an average process.

Comment: This is a market activity. Each market represents the consumption mix of a product in a given geography, connecting suppliers with consumers of the same product in the same geographical area. Markets group the producers and also the imports of the product (if relevant) within the same geographical area. They also account for transport to the consumer and for the losses during that process, when relevant. This is the market for 'krypton, gaseous', in the Global geography. This is a constrained market for consequential system model, for attributional system models, this is a regular market. In the case of consequential system model, details about the marginal consumer can be found in the comment of the conditional exchange (by-product). Transport from producers to consumers of this product in the geography covered by the market is included. 'krypton, gaseous' is an inorganic substance with a CAS no. : 007439-90-9. It is called 'krypton' under IUPAC naming and its molecular formula is: Kr. It is gas under normal conditions of temperature and pressure. The substance is modelled as a pure substance. There is no publicly available information about the consumption of this substance on a consumer level. On industrial sites, the substance is used for the manufacture of products in the following sectors: research, pharmaceuticals. This market is supplied by the following activities with the given share: air separation, xenon krypton purification, CA-QC: 0.00444285714285715 air separation, xenon krypton purification, RER: 0.21531007437896 air separation, xenon krypton purification, RoW: 0.780247068478183 generalComment of air separation, xenon krypton purification (RoW): The process describes the production of pure xenon and krypton derived from a crude concentrate from a cryogenic air separation process. As products only gaseous xenon and gaseous krypton were considered. Oxygen that is used as carrier material and returned to the air separation process is not considered. The allocation factors were calculated from the sales price of xenon and krypton in Europe in the year 1998. The ressources xenon, krypton were allocated to 100% to the corresponing product. [This dataset was already contained in the ecoinvent database version 2. It was not individually updated during the transfer to ecoinvent version 3.
