Abstract
Abstract A mobile vehicle is utilized to process hydrocarbons having high toxicity due to the presence of PCB. Hydrocarbons containing PCB are blended with metallic sodium at a temperature of about 130° C. and thereafter the mixture is separated into its components one of which is a hydrocarbon containing less than about 2 ppm of PCB.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
Apparatus for removing PCB from hydrocarbons comprising a common support for the following components and the components themselves: a filter for removing water from hydrocarbons, a reactor, a heat exchanger for heating hydrocarbons containing PCB, a vessel selectively communicating with said reactor for introducing sodium into the hydrocarbons for reacting with the chlorine in the PCB, and a separator for separating reactant sodium chloride and phenyl polymer from the hydrocarbon having less than two ppm PCB, the outlet of said filter being connected to said reactor, an outlet of said reactor being coupled to an inlet of said heat exchanger and an outlet of said heat exchanger being coupled to an inlet of said reactor so that hydrocarbon containing PCB may flow through a closed circuit including said reactor and said heat exchanger, an outlet of said reactor being coupled to an inlet of said vessel and an outlet of said vessel being connected to an inlet of said reactor so that hydrocarbons containing PCB may selectively flow through a closed circuit including said reactor and said vessel, an outlet of said reactor being connected to an inlet of said separator.
Claim 2
Dependent Claim
191 words

Claim 3
Dependent Claim
26 words
Apparatus in accordance with claim 1 wherein said common support is a mobile vehicle adapted to be transported to the site of hydrocarbons to be decontaminated.
Claim 4
Dependent Claim
20 words
Apparatus in accordance with claim 1 wherein the inlet in said first mentioned filter includes a pump and flow meter.
Claim 5
Dependent Claim
62 words
Apparatus in accordance with claim 1 wherein the separator comprises a housing, a filter member within said housing, said filter member having a perforated lower portion and containing a filter material, and a standpipe located within said filter member so that the hydrocarbons flow into said housing, through the perforations in said filter member, through said filter material and down said standpipe.
Claim 6
Dependent Claim
13 words
Apparatus in accordance with claim 4 wherein the filter material is steel wool.
Claim 7
Dependent Claim
40 words
Apparatus in accordance with claim 1 including means to selectively couple said reactor, said heat exchanger and said vessel so that hydrocarbons containing PCB may selectively flow through a closed circuit including said reactor, said heat exchanger and said vessel.
