- Equipment protecting enclosures
- (57) Abstract
Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, in a vault in which the equipment is protected from radiation and hazardous gases by equipment enclosures. The equipment enclosures may be purged with gas.

Claims (17)
- A method of protecting material processing equipment, the method comprising; conveying a biomass material under an electron beam on a conveyor; and enclosing motor components in an equipment enclosure that does not surround the conveyor and that is opaque to ionizing radiation; and purging the enclosure with a gas selected from the group consisting of oxygen reduced air, nitrogen, argon, helium, carbon dioxide, and mixtures thereof.
- The method of claim 1, further comprising exchanging the gas in the equipment enclosure at an exchange rate of less than once every 10 minutes.
- The method of claim 1, wherein the conveyor is disposed within a vault.
- The method of claim 3, wherein the vault also contains irradiating equipment.
- The method of claim 1, wherein the gas is provided from within the enclosure and the method further comprises filtering the gas prior to purging the equipment enclosure with the gas.
- The method of claim 5, wherein the gas has been filtered to remove ozone.
- The method of claim 1, wherein the method further includes moving the equipment enclosure to access the motor components.
- The method of claim 7, wherein the equipment enclosure is configured to be movable.
- The method of claim 1, wherein the equipment enclosure includes lead.
- The method of claim 1, wherein the exposure of the motor components to radiation is reduced by at least 10% as compared to the radiation exposure that would occur without the equipment enclosure.
- The method of claim 1, wherein the conveyor is a vibratory conveyor.
- The method of claim 11, further comprising providing a gap between the equipment enclosure and the vibratory conveyor to accommodate movement of components of the vibratory conveyor during use.
- The method of claim 1, wherein the exposure of the motor components to ionizing radiation is reduced by at least 20% as compared to the radiation exposure that would occur without the equipment enclosure.
- The method of claim 13, wherein the exposure of the motor components to ionizing radiation is reduced by at least 30% as compared to the radiation exposure that would occur without the equipment enclosure.
- The method of claim 14, wherein the exposure of the motor components to ionizing radiation is reduced by at least 50% as compared to the radiation exposure that would occur without the equipment enclosure.
- The method of claim 15, wherein the exposure of the motor components to ionizing radiation is reduced by at least 70% as compared to the radiation exposure that would occur without the equipment enclosure.
- The method of claim 16, wherein the exposure of the motor components to ionizing radiation is reduced by at least 90% as compared to the radiation exposure that would occur without the equipment enclosure.
Description
This application is a continuation application of U.S. patent application Ser. No. 14/434,953, filed Apr. 10, 2015, which is a National Stage of International Application No. PCT/US2013/064317, filed Oct. 10, 2013, which claims the benefit of U.S. Provisional Application Nos. 61/711,801, filed on Oct. 10, 2012; 61/711,807, filed on Oct. 10, 2012; 61/774,684, filed on Mar. 8, 2013; 61/774,773, filed on Mar. 8, 2013; 61/774,731, filed on Mar. 8, 2013; 61/774,735, filed on Mar. 8, 2013; 61/774,740, filed on Mar. 8, 2013; 61/774,744, filed on Mar. 8, 2013; 61/774,746, filed on Mar. 8, 2013; 61/774,750, filed on Mar. 8, 2013; 61/774,752, filed on Mar. 8, 2013; 61/774,754, filed on Mar. 8, 2013; 61/774,775, filed on Mar. 8, 2013; 61/774,780, filed on Mar. 8, 2013; 61/774,761, filed on Mar. 8, 2013; 61/774,723, filed on Mar. 8, 2013; and 61/793,336, filed on Mar. 15, 2013, all of which are hereby incorporated by reference in their entireties.
Many potential lignocellulosic feedstocks are available today, including agricultural residues, woody biomass, municipal waste, oilseeds/cakes and seaweed, to name a few. At present, these materials are often under-utilized, being used, for example, as animal feed, biocompost materials, burned in a co-generation facility or even landfilled.
Lignocellulosic biomass includes crystalline cellulose fibrils embedded in a hemicellulose matrix, surrounded by lignin. This produces a compact matrix that is difficult to access by enzymes and other chemical, biochemical and/or biological processes.
