A method of removing pollutants from flue gas includes cooling the flue gas to remove condensed water. The flue gas is then compressed and dehydrated. The dehydrated flue gas is chilled to separate pollutants.

Cryogenic separation of carbon dioxide, sulfur oxides, and nitrogen oxides from flue gas

The present disclosure is directed to a new and improved separation process that isolates individual minerals from brines containing a mixture of minerals. The brines may be derived from seawater, brackish water, oilfield brines, solution mining, mine run-off, and other sources. Typically, the minerals are recovered as chlorides using a variety of processing steps including evaporation, centrifugation, elutriation, filtration, electrocogulation, crystallization, adsorption, and chromatography.

Mineral recovery from concentrated brines

An embodiment of the disclosure provides a universal sealing apparatus for one or more cannulas. The apparatus includes a first portion, a second portion, and a third portion. The first and second portions are configured to removably adhere directly or indirectly to a nose. The third portion is coupled to the first and second portions. The third portion removably couples to one or more cannulas and places a force upon a base of flared portions of the one or more cannulas when the first and second portions are adhered to the nose. The force maintains a fluid seal of the one or more cannulas within one or more respective nostrils of the nose.

Air-delivery system for breathing-assist devices

According to one embodiment of the invention, a gerotor apparatus includes a first gerotor, a second gerotor, and a synchronizing system operable to synchronize a rotation of the first gerotor with a rotation of the second gerotor. The synchronizing system includes a cam plate coupled to the first gerotor, wherein the cam plate includes a plurality of cams, and an alignment plate coupled to the second gerotor. The alignment plate includes at least one alignment member, wherein the plurality of cams and the at least one alignment member interact to synchronize a rotation of the first gerotor with a rotation of the second gerotor.

Gerotor apparatus having outer gerotor with strengthening members

A system and method are presented for improved performance of gerotor compressors and expanders. Certain aspects of the disclosure reduce porting losses in a gerotor system. Other aspects of the disclosure provide for reduced deflection in lobes of an outer rotor of a gerotor system. Still other aspects of the disclosure provide for reduced leakage through tight gaps between components of a gerotor system.

Gerotor with reduced leakage

According to one embodiment, an open brayton bottoming cycle includes a heat exchanger configured between a compressor and an expander. The heat exchanger is configured to receive heat from a heat source and supply at least a portion of the exhaust heat to an expander using a fluid. The compressor configured to supply compressed fluid to the heat exchanger. The expander has a shaft connected to the compressor and configured to supply energy to the compressor. At least one of the compressor or the expander has an efficiency greater than 80 percent.

Open brayton bottoming cycle and method of using the same

According to one embodiment of the invention, a gerotor apparatus includes an outer gerotor having an outer gerotor chamber, an inner gerotor, at least a portion of which is disposed within the outer gerotor chamber, and a synchronizing apparatus operable to control the rotation of the inner gerotor relative to the outer gerotor. The inner gerotor includes one or more entrance passages operable to communicate a lubricant into the outer gerotor chamber.

Gerotor apparatus for a quasi-isothermal Brayton cycle engine

According to one embodiment of the invention, an engine system comprises a housing, an outer gerotor, an inner gerotor, a tip inlet port, a face inlet port, and a tip outlet port. The housing has a first sidewall, a second sidewall, a first endwall, and a second endwall. The outer gerotor is at least partially disposed in the housing and at least partially defines an outer gerotor chamber. The inner gerotor is at least partially disposed within the outer gerotor chamber. The tip inlet port is formed in the first sidewall and allows fluid to enter the outer gerotor chamber. The face inlet port is formed in the first endwall and allows fluid to enter the outer gerotor chamber. The tip outlet port is formed in the second sidewall and allows fluid to exit the outer gerotor chamber.

Methods and apparatus for treating biomass that may include introducing a biomass to a chamber; exposing the biomass in the chamber to a shock event to produce a shocked biomass; and transferring the shocked biomass from the chamber. In some aspects, the method may include pretreating the biomass with a chemical before introducing the biomass to the chamber and/or after transferring shocked biomass from the chamber.

Biomass shock pretreatment

According to one embodiment of the invention, a gerotor apparatus includes a first gerotor, a second gerotor, and a synchronizing system operable to synchronize a rotation of the first gerotor with a rotation of the second gerotor. The synchronizing system includes a earn plate coupled to the first gerotor, wherein the cam plate includes a plurality of cams, and an alignment plate coupled to the second gerotor. The alignment plate includes at least one alignment member, wherein the plurality of cams and the at least one alignment member interact to synchronize a rotation of the first gerotor with a rotation of the second gerotor.

Sealing system for gerotor apparatus

A method of producing hydrocarbons from biomass that includes converting at least a portion of the biomass into a first product having at least one of a carboxylic acid, a ketone, an ammonium carboxylate salt, and combinations thereof; converting at least a portion of the first product into an alcohol; reacting at least some of the alcohol in an oligomerization reactor as part of a process that produces an oligomerization product.

Alternative paths to alcohols and hydrocarbons from biomass

A method of producing alcohols, hydrocarbons, or both from biomass, the method including converting biomass into a carboxylic acid; reacting the carboxylic acid with an olefin to produce an ester; and hydrogenolyzing the ester to produce alcohol. The steps of reacting the carboxylic acid with an olefin to produce an ester, and hydrogenolyzing the ester to produce an alcohol, may both be carried out in the same reactor.
