[0023] FIG. 1 is a plan view of an example umbilical corridor 100 coupled to a plurality of modular cube structures 102 in accordance with an example embodiment of the present disclosure. Umbilical corridor 100 is formed from a plurality of hollow elongate corridor segments 104 coupled together using flanges 106 formed integrally into each corridor segments 104. Corridor segments 104 have a predetermined length 108. Each of the plurality of corridor segments 104 includes a first end flange 110 couplable to a complementary second end flange 112 of an adjacent one of the plurality corridor segments 104. Each of the plurality of corridor segments 104 may also include a side flange 114 couplable to a complementary end flange 116 of an adjacent modular cube structure 102. Each corridor segments 104 also includes a plurality of service conduits (not shown in FIG. 1) extending from end flange 116 of corridor segment 104 to at least the side flange 114 of the respective corridor segment 104. Typically, the plurality of service conduits extends from end flange 116 to an opposite end flange of corridor segment 104.

[0024] FIG. 2 is a perspective end view of a corridor segment 104 (shown in FIG. 1). In the example embodiment, corridor segment 104 includes a floor member 202 and a roof member 204 extending the predetermined length 108. Second end flange 112 circumscribes a hollow passageway interior 206. Second end flange 112 includes a plurality of members coupled together to provide a mating surface 208 for adjacent corridor segments 104 to be connected together. Second end flange 112 includes a vertical flange member 210 including a structural column member 212 and a cube corner assembly 214 fixedly coupled to at least one end of structural column member 212. In some embodiments, second end flange 112 includes a single cube corner assembly 214 in at least some corners of second end flange 112. In other embodiments, second end flange 112 includes a plurality of single cube corner assemblies 214 in at least some corners of second end flange 112. While described as being couplable together end-to-end, adjacent corridor segments 104 can also be configured to couple together side-by-side.

[0025] A plurality of service conduits 216 may extend between the first end flange 110 and second end flange (not shown in FIG. 2) within floor member 202 and/or within roof member 204. A distal end 218 of conduits 216 are fitted with couplings (not shown in FIG. 2) that are complementary with couplings of an adjacent corridor segment 104. In various embodiments, the plurality of service conduits include at least one of electrical supply conduits, control and instrumentation signal conduits, plumbing conduits, sewer/waste liquid conduits, heating, ventilating, and air conditioning (HVAC) conduits, and security and surveillance signal conduits.

[0026] FIG. 3 is a plan view of a plurality of corridor segments 104 coupled together end-to-end to form umbilical corridor 100.

[0027] FIG. 4 is a plan view of another example of a modular cube structure 102 that may be used with umbilical corridor 100 shown in FIG. 1. In the example embodiment, modular cube structure 102 includes a plurality of rooms, which may be configured to support a particular step of a process. The process may entail the cultivation of plant or animal life, the harvesting of the plant or animal life, processing the plant or animal life, extracting valuable materials from the plant or animal life, and preparing the residue of the plant or animal life for disposal. Some of the rooms are configured to support potentially hazardous operational steps or hazardous material within them. Some of the rooms may be subject to industrial codes or other restrictions on their construction or processes. For example, a first room 402 may be a production/operation where aspects of the process are carried out, initiated, monitored, and/or controlled. A second room 404 may include a freezer 406 and an area 408 that supports freezer process operations. A third room 410 may be used for an extraction step of the process. An extraction step may remove the valuable material from the plant or animal life being processed. Such a step may yield the valuable component being sought, waste gases, and waste solids. The waste gases may need to be captured for a forced air exhaust system 412 and exhausted outside modular cube structure 102 before the waste gas builds to a hazardous concentration. In the example embodiment, a fourth room 414 includes two additional production rooms 416 and 418 to facilitate increasing production levels of the valuable component.

[0028] FIG. 5 is a plan view of an exemplary joint 500 between adjacent ones of the umbilical corridor segments 104 (shown in FIGS. 1 and 2). A plurality of service conduits 216 may extend between the first end flange 110 and second end flange 112 within floor member 202 and/or within roof member 204 (shown in FIG. 2). A distal end 218 of conduits 216 are fitted with couplings 502 that are complementary with couplings 504 of an adjacent corridor segment 104. In some embodiments, pigtails 506 are used to bridge a gap 508 between couplings 502 and 504. Each pigtail 506 includes a length 510 of appropriate conduit 512 and mating couplings 514 on each end 516.

[0029] FIG. 6 is a front elevation view of third extraction room 528 (shown in FIG. 5) that may be used for an extraction step of the process.

Third extraction room 528 includes a fan balance controller 632 configured to maintain a predetermined pressure within processing enclosure 604. Fan balance controller 632 is also configured to maintain a predetermined flow through processing enclosure 604. Fan balance controller 632 includes at least one of a flow sensor 634 and a pressure sensor 636 configured to supply signals to fan balance controller 632 relative to a flow into processing enclosure 602 and a pressure within processing enclosure 602, respectively. Fan balance controller 632 further includes a hydrocarbon gas sensor 638 configured to initiate an off-normal operational sequence of fans 626 and 628 to increase air and/or diluent flow through processing enclosure 604 when a hydrocarbon gas concentration in processing enclosure 604 exceeds a predetermined value. Third extraction room 528 includes a conditioned air supply duct 640 coupled in flow communication with a heat pump or other flow conditioner (not shown in FIG. 6) to maintain a selectable temperature within processing enclosure 604. A vent connection extends from processing enclosure 602 directly into exhaust stack 606 for venting pressurized containers.

[0032] FIG. 8 is a flow chart of an example method 800 of extracting a component of a quantity of bio-matter. In the example embodiment, method 800 includes maintaining 802 a first flow of diluent through a processing enclosure of a multi-enclosure extraction room of a modular cube structure, the extraction room including an equipment enclosure and an exhaust stack.

Method 800 further includes monitoring 806 a concentration of at least one solvent of a plurality of solvents used in the extraction process, receiving 808 a container of bio-matter into the processing enclosure, and maintaining 810 a second flow of diluent through a processing enclosure when the concentration of the at least one monitored solvent exceeds a threshold range, the second flow of diluent greater than the first flow of diluent.

[0033] In some embodiments, the multi-enclosure extraction room includes an equipment enclosure and an exhaust stack. Method 800 optionally includes receiving a container of bio-matter into the processing enclosure of the multi-enclosure extraction room. In various embodiments, fan balance controller 632 is configured to maintain a negative pressure in the processing enclosure using fans 626 and/or 628 positioned in the equipment enclosure or the exhaust stack. In other embodiments, method 800 includes receiving a container of bio-matter into the processing enclosure that includes a solvent within the container. The solvent may be in a gaseous, liquid, or supercritical form and may be under pressure within the container. In such a case, the solvent may leak into the processing enclosure and present a problem for equipment and for personnel working within the processing enclosure. Any pressure in the container may be vented through a vent connection to the exhaust stack from the processing enclosure. In some embodiments, it may be necessary to repressurize the container with the same or a different solvent.
