Atkinson and Bourguignon (2000) ‘lack research that integrates distribution centrally into the examination of how the economics works’. To fill in such lack this study put in touch recent developments from Inequality Measurement and National Accounting literatures. This paper presents a reduced and rearranged Social Accounting Matrix (SAM) taking forward chapter 20 of SNA93 and after showing the limits of Jacobi multipliers to analyse inequality, this study proposes the calculation of border norms when distributive judgements are not robust.
Supercritical water oxidation (SCWO) has been shown to be an appropriate technology for the treatment of water containing toxic and hazardous substances, because it provides high destruction ef®ciencies. This paper reports a study of alternatives, and optimisation of various parameters and conditions, which are applied to the design of a mobile treatment unit. Phenol was selected as a model organic compound present in the feed stream and NaCl was selected as a model polar compound for solid separation. Pilot plant results show that ef®ciencies above 99.9% in phenol destruction are reached, at an operation temperature of about 650°C, with stoichiometric amounts of air. Feed streams with a wide range of heating values (lower limit 530 and upper limit 930 kJ kg À1 ) can be handled, because these values allow both thermal and mechanical energy recoveries, which are the key factor for economic feasibility. The unit is capable of handling wastewater containing toxic, recalcitrant or nonbiodegradable compounds that cannot be treated with global streams at the wastewater treatment plant of a factory. It is speci®cally proposed for use in industries in which wastewater contains solvent mixtures of ®ne chemicals and pharmaceuticals.

Water above its critical point (Tc = 374°C, Pc = 22 MPa), is a suitable medium to oxidise organics because it provides a very high solubility for both organics and gases and because the relatively high temperatures provide rapid oxidation rates. Detailed information on SCWO processes 1±4 and the properties of supercritical water are found in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
