Salt Waste Processing Facility

In 2001, the SRS announced its choice of CSSX as the baseline cesium-removal technology over small-tank precipitation (a small-scale version of the ITP process) and ion exchange with CST for its Salt Waste Processing Facility (SWPF) to go into operation in 2010 [22], An optimized solvent system, model, and flowsheet were developed and demonstrated in 2001 and 2002 [37,49], and a modular concept was developed by ORNL in 2003 [68], Thus, the past decade has seen the emergence and maturation of a powerful new technology based on a macrocyclic cation receptor designed to function in solvent extraction to meet the critical need of the USDOE for a means of cleanly separating Cs from alkaline tank waste. [Pg.385]

A SETFICS countercurrent hot test was recently conducted with high loading of salt-free flowsheet (in order to reduce the solvent volume and the amount of waste stream by 50%) in the JAEA Chemical Process Facility (CPF) as part of the feasibility demonstration of the NEXT process. The solvent consisted of CMPO and TBP,... [Pg.167]

Chlorine in elemental or hypochlorite salt form is a strong oxidizing agent in aqueous solution and is used in water treatment for disinfection, and in industrial waste treatment facilities primarily to oxidize cyanide. Chlorine and hypochlorites can also be used to oxidize phenol-based chemicals, but their use is limited because of the formation of toxic chlorophenols if the process is not properly controlled. [Pg.491]

Closely related to the previous process is the plastic waste gasification facility being set up at Rotterdam with a capacity of 150 tonnes day-1 of plastic wastes.13 The feed of this plant will be a mixture of polyethylene, polypropylene and polystyrene with minor amounts of other polymers (2.4 wt% of PVC) and a significant proportion of cellulose. The plan is that an injection of ammonia into the gasifier will neutralize the chlorides entering with the plastic wastes, which will lead to the formation of ammonium chloride salt as a by-product. A production of 350 000 m3 day -1 of synthesis gas is estimated, which will be used in chemical synthesis. [Pg.66]

Due to its closed liquid loops for water and electrolytes only about SO m salt brine per year based on the 500 tons/year battery capacity has to be transferred to a waste water facility outside. The dust and activated carbon filters keep the process emissions to acceptable legal and environmental limits. [Pg.197]

Waste streams with a high chlorine content require dilution before processing to limit corrosion of the vessel. Due to the 10% by weight solids limitation, there is an inherent large dilution ratio required for solid materials. No SGPV facilities are recommended in salt domes or in areas where the vessel will cross a seismic fault line. [Pg.612]

Civilian applications are numerous, but most funding of SCWO technology has stemmed from the military s need to find a safe and effective alternative to incineration of their wastes, as well as the need to clean up mixed wastes (radioactive and hazardous organic materials) at DOE weapons facilities. For better utilization of SCWO for its application to a wide range of waste types, a better fundamental understanding of reaction media, including reaction rates, reaction mechanisms, and phase behavior of multicomponent systems is required. Such an understanding would help optimize the process conditions to minimize reactor corrosion and salt... [Pg.162]

Mound Facility Low-Risk Waste. Approximately 3 x 105 l of low-level waste are generated weekly at the Mound Facility. This particular waste stream is essentially local hard water which has been demineralized and then used in various chemical processes involving the radionuclides 238Pu and 233U. The first step in decontaminating the low-risk wastes entails addition of small amounts of calcium and iron salts followed by addition of NaOH to pH 11.5 to precipitate iron and calcium hydroxides and carbonates. The clarified effluent from the precipitation step is then passed through a 200 micrometer sand filter to yield a solution containing, typically, 0.1+ d/min/m alpha activity. [Pg.25]

Toxco, Inc. has developed processes to recover lithium as lithium carbonate from lithium batteries and other types of lithium-containing wastes [30]. As much as 98% of the available lithium can be recovered, along with a similar fraction of the available cobalt (Co) and much of the aluminum (Al), iron (Fe), and nickel (Ni). The lithium carbonate can be returned to lithium production and Pacific Lithium, Ltd. has done this. More recently, Toxco has acquired facilities to convert the lithium carbonate back into electrolyte salts for lithium batteries. Clearly, it is feasible and profitable to recycle the cobalt cathode and lithium components of these batteries. [Pg.316]
