In an economical and efficient process and apparatus for producing biofuel from waste oil, such as vegetable oils and animal fats, waste oil is esterified with alcohols to produce alcohol esters and the by-products of the transesterification reaction are recovered. Static pressure may be used as well as continuous flow-through reaction vessels and separation tanks without the need for additional pumps. There may also be specialized reaction tanks that have vertical rotating feed tubes having separators and inlet and outlet openings. The method and device achieves efficient production of biofuel while employing reaction and mixing tanks having a limited size, which in turn permits a smaller plant layout or “footprint”. For example, the largest tank may be in a size of about 36/100,000 times the desired plant output in gallons per year. The benefits of the process and apparatus include minimal space for a plant; minimal on-site feedstock needed therefore minimal on-site storage is needed; minimal capital costs to build a plant e.g., reduction by about fifty to sixty five percent (50 to 65%); reduction in construction time from typically over one year to under three months in many plants; minimal energy usage, e.g., reduction by about sixty percent (60%); minimal labor costs due to the automatic continuous flow; minimal pumps needed thereby reducing pump operation and maintenance costs; environmentally friendlier and safer plant design; and due to smaller plant footprint, lower capital cost and minimal construction time enables site selection much nearer to the raw material supplies, thereby minimizing or even eliminating transportation costs for yellow grease or vegetable oil.

An exemplary method for the operation of a CCPP with flue gas recirculation to reduce NOx emissions and/or to increase the CO2 concentration in the flue gases to facilitate CO2 capture from the flue gases as well as a plant designed to operate is disclosed. To allow a high flue gas recirculation ration (rFRG) an imposed combustion inhomogeneity ratio (ri) is used for flame stabilization. The imposed combustion inhomogeneity ratio (ri) is controlled as function of the flue gas recirculation rate (rFRG) and/or combustion pressure. Oxygen or oxygen enriched air to the gas turbine inlet gases or to the combustor is admixed to enhance operatability.

The innovation herein proposed describes a plant to produce electricity by the sea waves. The plant is designed to be installed on shore, near shore and offshore scenarios: on the coast line, in shallow waters and in deep waters. The plant is operated by action of the sea waves on a series of floaters (A). The resultant force on each floater (A) acts on a mechanical load amplifier (B) which moves two vertical high pressure piston pumps (C). These pumps (C) send pressurized fresh water to a hyperbaric system (E). The hyperbaric system (E) supplies an outflow water jet through a controlled valve that moves a conventional turbine (G). This turbine (G) connected to the electric generator (H) produce electricity.

A reformation power plant generates clean electricity from carbonaceous material and high pressure CO₂ which can be easily sequestered or utilized for a beneficial purpose, such as fuel production. The reformation power plant design utilizes a reformation process that reforms carbonaceous fuel with super-heated steam into a high-pressure gaseous mixture that is rich in carbon dioxide and hydrogen gas. This high-pressure gas exchanges excess heat with the incoming steam from a boiler and continues onward to a condenser. Once cooled, the high-pressure gas goes through a methanol separator, after which the CO₂-rich gas is sequestered underground or beneficially re-used. The remaining hydrogen-rich gas is combusted through a gas turbine. The gas turbine provides power to a generator and also regenerative heat for the boiler. Finally, the generator converts mechanical energy into electricity, which is transferred to the electric grid. Therefore, carbon-free electricity is generated from coal, biomass, or other carbon-based feedstock.

One process provides for operation of a bitumen froth treatment plant at optimum shear rates in the feed pipe carrying the bitumen froth to the froth settling unit. Another process provides for optimizing the design of a bitumen froth treatment plant by optimizing the diameter of the feed pipe to impart an optimum shear rate to the bitumen froth mixture and further optimizing the volume of the feed pipe to impart an optimum residence time for the bitumen froth stream in the feed pipe. An optimal plant design is also disclosed, the plant including optimal diameter and volume of the feed pipe.

An intelligent plant development library environment is presented. Contemplated environments comprise an EPC knowledge system capable of incorporating know-how of one or more construction firms in the form of assembly objects. Assembly objects represent construction components (e.g., bolts, cable trays, pipes, processing units, deliverables, etc.) that can be incorporated into a plant design. Assembly objects are stored in an assembly database and include available contexts considered relevant to the assembly objects. An inference engine is utilized to derive a specified context related to a plant design from one or more design tools. The inference engine applies rule sets to infer which assembly objects to instantiate as construction objects. The inference engine can further configure the design tools to incorporate the instantiated construction objects into a plant construction project model. Example rule sets include forward chaining rules, backward chaining rules, case-based reasoning rules, inductive reasoning rules, or abductive reasoning rules.
