Flow regulated pressure swing adsorption system

Pressure swing adsorption (PSA) separation of a gas mixture is performed in an apparatus with a plurality of adsorbent beds. The invention provides rotary multiport distributor valves to control the timing sequence of the PSA cycle steps between the beds, with flow controls cooperating with the rotary distributor valves to control the volume rates of gas flows to and from the adsorbent beds in blowdown, purge, equalization and repressurization steps.

System and method for sequestration and separation of mercury in combustion exhaust gas aqueous scrubber systems

A process, system and sorbent for removal of mercury from a combustion exhaust gas stream in a combustion exhaust gas purification scheme that includes a combustion exhaust scrubber system that uses an aqueous liquid to remove acid gases from the combustion exhaust gas. A powdered mercury sorbent is used. The sorbent is introduced into the aqueous scrubber liquid in the scrubber system. After introduction of the mercury sorbent into the scrubber liquid, at least some of the mercury sorbent is separated from the scrubber liquid.

Methods and devices for the production of Hydrocarbons from Carbon and Hydrogen sources

Devices and methods are described for converting a carbon source and a hydrogen source into hydrocarbons, such as alcohols, for alternative energy sources. The influents may comprise carbon dioxide gas and hydrogen gas or water, obtainable from the atmosphere for through methods described herein, such as plasma generation or electrolysis. One method to produce hydrocarbons comprises the use of an electrolytic device, comprising an anode, a cathode and an electrolyte. Another method comprises the use of ultrasonic energy to drive the reaction. The devices and methods and related devices and methods are useful, for example, to provide a fossil fuel alternative energy source, store renewable energy, sequester carbon dioxide from the atmosphere, counteract global warming, and store carbon dioxide in a liquid fuel.

Integrated photobioreactor-based pollution mitigation and oil extraction processes and systems

Integrated systems including a photobioreactor system designed to contain a liquid medium comprising at least one species of phototrophic organism therein, and a facility associated with extracting and / or processing oil extracted from mixtures of oil and solid material, such as an oil sands facility, are described. Processes for using a photobioreactor system as part of a gas-treatment process and system able to at least partially remove certain undesirable pollutants from a byproduct gas stream produced by an oil sands facility are also described. Examples of such pollutants that may be removed include compounds contained within combustion gases, e.g., CO2 and / or NOx. These pollutants processed with the photobioreactor system, and, in some embodiments, biomass produced with the photobioreactor system may be utilized to produce a fuel source (e.g., biodiesel) and cutting stock for further operation of or use in the oil sands facility. Such uses of certain embodiments can provide an efficient means for recycling carbon, thereby reducing CO2 emissions, fuel, and / or cutting stock requirements for a given quantum of energy produced. In addition, in some cases the photobioreactor can be integrated with a holding pond and waste heat from the oil extraction process can be used to maintain the photobioreactor temperature and / or provide energy for other processes. Accordingly, embodiments described herein can improve the overall environmental and economic profile of the oil sands facility.
