According to the vendor, the HT-6 technology is not a destruction process but a separation process technology. The process cleans the soil and concentrates the organics into an organic oil phase. For refinery wastes, coal tar wastes, and creosote, this oil is directly suitable for commercial reuse as a refinery feedstock. The high-temperature thermal distillation technology is not currently commercially available. 

The high-temperatnre thermal distillation technology is not applicable to metal-only wastes, with the exception of mercnry, which has a boiling point below 2000°F (1090°C). 

It is apparent that around 1925 distillation equipment in the petroleum industry varied in design and complexity from the simple horizontal shell stills with fractional vapor condensation to the continuous pipe stills with the progenitor of the present bubble cap fractionating columns. The basic processing principles were being rapidly extended, and the foundation was well established for the further development of distillation technology. 

Carbon dioxide removal by reactive absorption in amine solutions is also applied on the commercial scale, for instance, in the treatment of flue gas (see later in this chapter). Another possible application field of the technique is gas desulfurization, in which H2S is removed and converted to sulfur by means of reactive absorption. Aqueous solutions of ferric chelates (160-162) as well as tetramethylene sulfone, pyridine, quinoline, and polyglycol ether solutions of S02 (163,164) have been proposed as solvents. Reactive absorption can also be used for NOx reduction and removal from flue or exhaust gases (165,166). The separation of light olefins and paraffins by means of a reversible chemical com-plexation of olefins with Ag(I) or Cu(I) compounds in aqueous and nonaqueous solutions is another very interesting example of reactive absorption, one that could possibly replace the conventional cryogenic distillation technology (167).

A prime application of graphical methods in modern distillation technology is for analyzing the results of computer simulations. Several of the graphical construction rules can be bent in order to benefit from computer accuracy and to reduce effort. Johnson and Morgan (28) described several key considerations their work is expanded here using the author s experience.
