Linde Gasification Process

Linde KC A in Germany offers another technology for feedstock recycling that has been developed on the 

In 1999, the European Council of Vinyl Manufacturers (ECVM) chose this process as the most robust and economical, and started to support it within the context of ECVM s recycling efforts. ECVM committed 3 million as a support to the building of a pilot plant. The pilot will be build at Solvay s Tavaux plant, located in the eastern part of Erance. If the pilot is successful, most probably a 25,000 tpa full scale plant will be build. However, it is not expected that such a full scale plant will be operational before 2005. 

In principle, this process recycles all types of PVC waste. No differentiation between PVC formulae has to be made. There are no particular acceptance criteria. The waste is conditioned as follows to be acceptable for the slag bath gasifier  

For the Linde process, a material and energy balance has been produced. If the input is some 3 toimes PVC per hour, some 3,500-4,000 m combustible gas and 700 m /h HCl (STP) is produced. No dioxins or furans are expected to be generated given the reducing atmosphere. 

As for costs, ECVM estimates that considering all costs the total gate fee must be around 200 per toime to break even for a 25,000 tpa plant. For pretreatment like grinding another 125 per toime might be needed. However, it is clear that reliable estimates can only be given after experience with the pilot plant has been evaluated.

The German Lurgi Company and Linde A. G. developed the Rectisol process to use methanol to sweeten natural gas. Due to the high vapor pressure of methanol this process is usually operated at temperatures of -30 to -100°F. It has been applied to the purification of gas 1 plants and in coal gasification plants, but is not used commonlv natural gas streams.
