Problems solved by technology

However, for a number of reasons, the use of this technique and equipment is limited to small laboratory-scale applications, and most are not suitable for scale-up to high-volume, high-throughput commercial use.
Expansion of scale and availability of equipment and instrumentation for some technologies is cost prohibitive
The high-volume flux of organic solvents also results in large hazardous waste streams, which require costly storage and disposal strategies

Embodiment 1

[0111] Example 1: Lab scale setup for generating a flow of PLP water through a chromatography column

[0112] An example of a laboratory-scale system 5 according to an embodiment of the present disclosure is shown in figure 1 in, and typically includes: a water supply 10, a pump 15 (e.g., Waters Model 515, Milford, MA), a temperature-controlled oven 20 (e.g., Fisher Scientific, Pittsburgh, PA) 851F type), preheating coil 25 (for example, 2.0m stainless steel pipe with an outer diameter of 3.2mm (1 / 8 inch), pressure column 30, 1.0m cooling coil 40 (outer diameter of 3.2mm (1 / 8 inch) 8 inches) of stainless steel tubing), a back pressure regulator 45 (Upchurch Technologies, Oak Harbor, WA) with a 5.2 MPa (750 psi) cartridge for maintaining pressure in the system, and a collection vessel 50. A pressure relief valve 35 is interposed between the preheating coil 25 and the pressure-resistant column 30 . Use stainless steel tubing (3.2 mm (1 / 8 in) OD) and connectors to connect equip...

Embodiment 2

[0113] Example 2: Commercial Scale Apparatus for Producing PLP Water Flow Through One or More Large Scale Chromatographic Columns

[0114] Another exemplary PLPW device 100 interconnected with two large chromatographic columns such as figure 2 As shown, the chromatographic columns 120, 121 have a maximum working pressure of 6200kPa (900psi) at a working temperature of 204°C. The column jacket is designed for a lower maximum working pressure of 2,580 kPa (375 psi) at an operating temperature of 204°C to prevent column breakage when the jacket is pressurized but not the column. However, because the temperature and pressure of various parts of the apparatus (accumulators 125, 126) have been shown to be lower than those of the columns 120, 121, the maximum operating pressure and temperature setting for the dual column system as a whole at a temperature of 5500 kPa (800 psi) and a temperature of 180°C, and the maximum working pressure of the jacket circuit 150 is 2400 kPa (350 ps...

Abstract

A method for separating, purifying, and recovering components from a liquid feedstock. The method steps include (i) commingling the liquid feedstock with a sorbent whereby one or more components in the liquid feedstock are bound onto the sorbent, thereby producing a loaded sorbent; (ii) packing the loaded sorbent into a first temperature-controlled pressure-resistant column; (iii) sealably engaging the first temperature-controlled pressure-resistant column with a supply of water, and cooling equipment for receiving a flow of an eluate from the temperature-controlled pressure- resistant column;(iv) from the supply of water, producing a first flow of PLP water at a first selected temperature; (v) flowing the first flow of PLP water through the temperature-controlled pressure-resistant column thereby producing a first flow of the eluate therefrom, said eluate containing the one or more components; (vi) cooling the first flow of the eluate; and (vii) collecting the cooled first flow of the eluate.

Description

technical field [0001] Various embodiments disclosed herein generally relate to apparatus, devices, and systems for isolating and purifying compounds from solutions containing multiple solutes. More specifically, the present disclosure relates to apparatus, devices and systems for generating and using pressurized low polarity water as a solvent utilizing sorbents that separate solutes from solutions. Background technique [0002] Ion exchange resins and other types of adsorbents are widely used in various high-volume production through separation, purification and purification processes. The most common ion exchange resins are based on cross-linked polystyrene. The four main types of ion exchange resins differ in their functional groups. The first group of ion exchange resins are strongly acidic and typically include sulfonic acid groups, eg sodium polystyrene sulfonate or polyAMPS. The second group of ion exchange resins are weakly acidic and generally contain carboxylic...
