A plasma gasification reactor vessel having a top section with a conical wall extending up from a bottom section, containing a carbonaceous bed into which plasma is injected by plasma torches, to a roof of the vessel is arranged in ways that can contribute to characteristics of gas flow and solids residence time that are favorable for thoroughness of reactions and yield of useful reactions products. In some cases, such a conical wall is combined in arrangements with other features such as one or more feed ports arranged to give more uniform distribution including examples with a feed port that has a distributive feed mechanism. The roof of the vessel, in some examples, has vertical outlet ports that include intrusions into the interior volume of the reactor proximate the conical wall of the top section. The configurations of outlet ports with intrusions and the configurations of feed ports for more uniform distribution of feed material are also applicable to reactor vessels with other geometries.

A system and process for upgrading hydrocarbons such as heavy oils includes a high temperature plasma reactor apparatus, in one or more vessels, into which the oils are introduced along with water, such as steam, to produce lighter hydrocarbon fractions, along with carbon monoxide and hydrogen, that flows to an additional stage where more hydrocarbons and water are introduced for further fractionating reactions facilitated by reaction of carbon monoxide and water to produce carbon dioxide and nascent, or prompt, free radicals of hydrogen. Heavy hydrocarbons upgraded can include heavy oils in the form of tar sands, oil shale, and oil residuals. The vessel or vessels can each contain a carbonaceous bed facilitating the described reactions and example embodiments include one vessel with the reactions performed in a single bed and, also, two vessels with the reactions performed in a carbonaceous bed portion in each vessel.

A process system is disclosed for the treatment of a waste sand material containing metal contaminants. The waste sand material is the product of sandblasting techniques used to remove paint. The metal contaminants generally include lead, copper, chromium, mercury and cadmium, among other heavy metals. The process particularly provides for the concentration of the lead contaminant in a waste sand that can be economically reclaimed or disposed in an environmentally safe manner. The process also produces a cleaned sand that contains only residual amounts of the metallic contaminants in environmentally acceptable levels. The process provides for the contacting of the waste sand material with a paint decomposer, attrition abrading this sand slurry, size separating the attrition abraded slurry to form a waste sand slurry and a cleaned sand, and removing a portion of the excess water content in the waste sand slurry.

A microcomputer-based real-time flash x-ray controller, which completely eliminates the 'guesswork' in capturing projectiles on radiographs. The microcomputer measures the projectile velocity with high precision, calculates the correct delays in real-time and sends out appropriate triggering pulses to activate the x-ray tubes, arbitrarily arranged along the projectile flight path, to capture the projectile on radiographs at desired locations. The system imposes virtually no restrictions on x-ray tube locations downrange. It is software driven, user friendly and fully programmable for various ballistic range set-ups and it can be easily adapted to synchronize the time-critical controls of other equipment such as high speed cameras, target instrumentations, and the like. The use of a personal computer, centralizes the range operations as equipment control and experiment record-keeping become an integral task.
