There is provided an optical device for transferring light within a given field-of-view, comprising an input aperture; reflecting surfaces, and an output aperture located in spaced-apart relationship from the input aperture such that light waves, located within the field-of-view, that enter the optical device through the input aperture, exit the optical device through the output aperture, wherein the reflecting surfaces are at least one pair of parallel reflecting surfaces and that part of the light waves located within the field-of-view that enter the input aperture, pass directly to the output aperture without being reflected off the at least one pair of parallel reflecting surfaces, while another part of the light waves within the field-of-view that enters the input aperture, arrives at the output aperture after being twice reflected by the at least one pair of parallel reflecting surfaces.

A system and process are disclosed for the controlled combustion of a wide variety of hydrocarbon feedstocks to produce thermal energy, liquid fuels, and other valuable products with little or no emissions. The hydrocarbon feeds, such as coal and biomass, are first gasified and then oxidized in a two-chamber system / process using pure oxygen rather than ambient air. A portion of the intermediate gases generated in the system / process are sent to a Fischer-Tropsch synthesis process for conversion into diesel fuel and other desired liquid hydrocarbons. The remaining intermediate gases are circulated and recycled through each of the gasification / oxidation chambers in order to maximize energy production. The energy produced through the system / process is used to generate steam and produce power through conventional steam turbine technology. In addition to the release of heat energy, the hydrocarbon fuels are oxidized to the pure product compounds of water and carbon dioxide, which are subsequently purified and marketed. The system / process minimizes environmental emissions.

In a process for producing an aromatic carboxylic acid, it is a dehydrating process which can achieve compactification of a step for removing water from a mixture of acetic acid and water produced in the production process, and which can reduce the consumed energy. In a production process of an aromatic carboxylic acid having an oxidation reaction step for producing a slurry of an aromatic carboxylic acid by carrying out liquid-phase oxidation reaction of an alkyl aromatic compound with an oxygen-containing gas in a solvent containing acetic acid in the presence of an oxidation catalyst, at least a portion of a mixture containing acetic acid and water produced in the production steps is separated into a permeable gas mainly comprising water and nonpermeable substances mainly comprising acetic acid, using a separation membrane having water selectivity.
