Abstract: An educational board game includes a board depicting a track with a plurality of spaces sized to accept player position tokens and a card set for each player containing questions or tasks designed to test the player's knowledge, with each player's card set differing based on the quantity of cards, the difficulty level, and/or the subject matter. Movement of the position tokens is determined by a random number generator. Some of the spaces on the track are designated draw spaces, directing the player to draw a card from the card set and attempt to give the correct response. A player may win the game by correctly responding to all cards in the card set. The variation between each player's card set allows players of differing skill levels to play at the same time.

Abstract: The present invention relates to an integrated gasification and hydroprocessing process. A hydrocarbonaceous fuel is first gasified to produce syngas, and then a portion of the hydrogen is removed from the syngas. The hydrogen is compressed and used as an excess reactant in a hydroprocessing unit. Hydrogen gas is recovered from the hydroprocessing unit product, purified, compressed and recycled to the hydroprocessing unit. The hydrogen-poor syngas is expanded in an expander that drives the compressor that compresses the recycled hydrogen gas. The expanded syngas is then combined with light hydrocarbons removed from the recycle hydrogen gas stream, combusted in a gas turbine and used for power generation.

Abstract: The primary object of the present invention is to provide a process and an apparatus to recover heat from a combustion engine turbine exhaust that involves exchanging heat between the combustion engine turbine exhaust and both a heat transfer medium and water. The exhaust is cooled in a series of heat exchange steps that ultimately produces a heated heat transfer medium fluid and superheated steam.

Abstract: Syngas for use, as fuel in the combustion turbine of an IGCC process is heated to a maximum temperature of about 350° F. (177° C.) prior to entering the combustor. Non-combustible diluent gas and additional fuel with a high heating value is also added to the syngas to increase the total heating value of the feed to the combustor of the gas turbine. The cooler temperature allows for more mass flow to the combustion turbine, allowing for greater sensible heat in the syngas to offset the latent heat loss due to the cooler temperature. Because the syngas/diluent feed steam is not heated to the high temperatures disclosed in the prior art, the steam that would otherwise heat the feed stream is available for power generation in the steam turbine, increasing its individual power output and the overall power output of the IGCC process.

Abstract: A hydrotreated liquid contains volatile hydrocarbons, hydrogen, and contaminants such as hydrogen sulfide. An inert gas, preferably nitrogen, is used to strip volatiles from the hydrotreated liquid. This stripper gas is then added to fuel gas fed to a combustion turbine, where combustibles in the fuel gas and stripper gas are combusted. The stripping is at a pressure sufficient to allow the stripper gas, now containing hydrocarbons and hydrogen, to be added to the combustion turbine fuel without additional compression. This process allows for efficient use of the stripped combustibles, and the nitrogen added to the fuel, gas provides increased power generation from the combustion turbine and reduces NOx emissions.

Abstract: This invention involves heat integration of a solvent deasphalting process with a gasification process and an improved process for separating a resin phase from a solvent solution comprising a solvent, deasphalted oil (DAO) and resin. This improved process comprises heating the solvent solution so as to precipitate the resin from the solvent solution, and then separating the resin and some solvent from the solvent solution. This will produce a resin product and a mixture comprising the DAO and the remaining solvent. The DAO/solvent mixture is then boiled so as to vaporize a fraction of the solvent, with waste heat from a gasification unit providing the heat source for the boiling. The vaporized solvent is removed from the DAO/solvent mixture leaving a resin-free DAO product that contains any unvaporized solvent. The vaporized solvent is used for heating the aforementioned solvent solution and preheating the resin-free DAO/solvent mixture.

Abstract: The high pressure syngas product of a gasifier is routed first to a high pressure absorber unit that removes most of the H2S and some of the CO2 from the syngas. The syngas is then released through an expander to reduce the pressure of the syngas and simultaneously generate electricity. Steam is then injected into the syngas as a reactant in the subsequent COS hydrolysis step, converting the COS to H2S. After hydrolysis, the syngas is routed to a reabsorber where the remainder of the H2S and CO2 are removed. Sweet syngas can then be sent to a combustion turbine for use as a fuel source.

Abstract: The present invention is a process to recover a high purity, high pressure hydrogen gas stream from synthesis gas. The synthesis gas is contacted with a membrane that separates the synthesis gas into a hydrogen-enriched permeate and a hydrogen-depleted non-permeate. The permeate is conveyed to a carbon dioxide absorber. The carbon dioxide absorber removes carbon dioxide using a solvent. The carbon dioxide-rich solvent from the absorber is heated and sent to a gas-liquid contactor, where the solvent is regenerated by nitrogen stripping. A small recycle stream of a regenerating gas, i.e., hydrogen, is subsequently contacted with the solvent, stripping entrained and dissolved nitrogen from the solvent. This stripping gas, the regenerating gas, or preferably both, are then mixed with the non-permeate for combustion in a combustion turbine.

Abstract: In this invention, a hydrogen recycle stream from a hydrotreater is heated before returning to the hydrotreater using the energy from a first shift reaction, thereby eliminating the need for a fired heater to heat the hydrogen recycle stream. This heat integration significantly reduces the overall capital and operating costs as well as emissions for the refinery because no fired heater is needed for the hydrotreater and no boiler is needed to cool the effluent from the first stage of shift.

Abstract: The invention is the integration of a process of gasifying asphaltenes in a gasification zone by partial oxidation and the process of asphaltene extraction with a solvent. The integration allows low level heat from the gasification reaction to be utilized in the recovery of solvent that was used to extract asphaltenes from an asphaltene-containing hydrocarbon material. Asphaltenes are extracted from an asphaltene-containing hydrocarbon material by mixing a solvent in quantities sufficient to precipitate at least a fraction of the asphaltenes. The precipitated asphaltenes are then gasified in a gasification zone to synthesis gas. The gasification process is very exothermic. The low level heat in the synthesis gas, either directly, or via an intermediate step of low pressure steam, is used to remove and recover the solvent from the deasphalted hydrocarbon material and from the asphaltenes prior to gasification.

Abstract: The invention is a process for separating acid gases from synthesis gas and treating the resulting solids. A mixture comprising synthesis gas and acid gas is contacted with a fluid that reacts with said acid gas to form a particulate solid dispersed in a fluid. The slurry comprising fluid and particulate solid is filtered to separate the particulate solid from the fluid by means of a regenerable filter. The particulate solids are removed from the regenerable filter by back-washing with a back-washing fluid to form a pumpable slurry comprising a mixture of particulate solids and back-washing fluid. The slurry is gasified to form synthesis gas and vitrified solids.

Abstract: An apparatus and a process for cooling a feed injector of a gasification reactor that produces synthesis gas is described. Cooling fluid is injected into a channel in the feed injector adapted for circulating the fluid. The injection pressure is maintained near or above the gasification reactor pressure. The fluid is withdrawn from the channel through an outlet at an outlet pressure between about 515 KPa above to about 1030 KPa below the gasification reactor pressure. The fluid is cooled, degassed, and injected back into the channel in the feed injector. The pressure on the cooling system is variable and tracks the gasification reactor pressure.

Abstract: The system for controlling oxygen flow in a gasification process of the instant invention comprises a suction control valve located between the oxygen source and the oxygen compressor. The suction control valve is adapted in order to open to deliver oxygen from the source to the compressor through the first pipe and to move to a reduced flow position to prevent excess delivery of oxygen from the source to the compressor. The system also comprises a second pipe which operably connects the oxygen compressor to a port of a gasifier. The system comprises a normally closed vent valve located between the oxygen compressor and the port of a gasifier. The system comprises a means located in the gasifier or in the gasifier effluent for detecting when it is necessary to change the oxygen flow to the gasifier and to actuate the suction control valve sufficient to change the oxygen flow.

Abstract: The invention is a process of degassing and cooling a hot black water slurry. The hot black water slurry is obtained from syngas scrubbers. The black water slurry is cooled and degassed by exposing the black water slurry to a vacuum under conditions sufficient to separate dissolved gases from the black water slurry. These gases are then removed from the black water slurry. These gases can advantageously be recycled in the gasification process.
