The techniques provide for a reconfigurable extraction column length based on the number of columns from a plurality of columns configured for use in an extraction apparatus. The apparatus includes a plurality of columns that each have an inlet, a central portion configured to hold extractable material during an extraction process, and an outlet. The reconfigurable extraction apparatus also includes a piping system connected to each of the plurality of columns that can selectively connect each of the plurality of columns, such that each column from the plurality of columns can be configured for an extraction process either singularly or in series or in parallel with one or more other columns from the plurality of columns, administering a solvent to one or more of the plurality of columns, and outputting the solvent after an extraction process occurs in the one or more of the plurality of columns.

The extraction method of claim 1, wherein the plurality of columns is configured vertically, the extraction method further comprising: providing, for at least one column from the plurality of columns, a solvent at a solvent inlet disposed at a top of the column so that the solvent can flow downwards through the column and out a solvent outlet disposed at a bottom of the column. 3. The extraction method of claim 1, wherein the plurality of columns is configured vertically, the extraction method further comprising: providing, for at least one column from the plurality of columns, a solvent at a solvent inlet disposed at a bottom of the column so that the solvent can flow upwards through the column and out a solvent outlet disposed at a top of the column. 4. The extraction method of claim 1, wherein the extractable material outlet of at least one of the columns of the plurality comprises a set of outlet valves including a first outlet valve and a second outlet valve, and the first outlet valve is disposed inwards towards the central portion of the column and the second outlet valve is disposed outside of the first outlet valve such that the second outlet valve is further away from the central portion than the first outlet valve, the extraction method further comprising: configuring the first outlet valve in an open position and the second outlet valve in an open position to discharge extractable material from the column. 5. The extraction method of claim 1, further comprising: configuring the piping system to isolate a column of the plurality of columns after the column has been used in an extraction process; andcleaning the column in place while other columns of the plurality of columns are still being used in the extraction process. 6. The extraction method of claim 1, further comprising: configuring the piping system to exhaust solvent from a first column of the plurality of columns after an extraction process is completed in the first column; andconfiguring the piping system to input the solvent exhausted from the first column into a second column of the plurality of columns. 7. The extraction method of claim 1, wherein the extractable material inlet of each column of the plurality has a corresponding set of inlet valves including a corresponding first inlet valve and a corresponding second inlet valve, and the method further comprising configuring each corresponding first inlet valve and each corresponding second inlet valve in an open position to fill each of the corresponding columns of the plurality with extractable material. 8. The extraction method of claim 1, wherein: the extractable material inlet of each column of the plurality has a corresponding set of inlet valves including a corresponding first inlet valve and a corresponding second inlet valve;the extractable material outlet of each column of the plurality has a corresponding set of outlet valves, each corresponding set of outlet valves including a first outlet valve and a second outlet valve, and the first outlet valve is disposed inwards towards the central portion of the corresponding column and the second outlet valve is disposed outside of the first outlet valve such that the second outlet valve is further away from the central portion than the first outlet valve; andthe extraction method further comprising: configuring each corresponding first inlet valve and each corresponding second inlet valve in an open position to fill each of the corresponding columns of the plurality with extractable material; andconfiguring each corresponding first outlet valve in an open position and each corresponding second outlet valve in an open position to discharge extractable material from the corresponding column. 9. The extraction method of claim 1, wherein at least one first inlet valve of the set of inlet valves comprises a valve member, the valve member having an open position and a closed position, and wherein the valve member includes a screen configured to prevent solids larger than a predetermined size from passing through the first inlet valve while allowing fluids to pass through the first inlet valve when the valve member is in the closed position. 10. The extraction method of claim 4, wherein the extractable material outlet of each column of the plurality has a corresponding set of outlet valves including a corresponding first outlet valve and a corresponding second outlet valve, and the method further comprising configuring each corresponding first outlet valve and each corresponding second outlet valve in an open position to discharge extractable material from the corresponding column. 11. The extraction method of claim 4, wherein at least one column of the plurality that has the set of inlet valves also has the set of outlet valves. 12.
