Abstract: A process and system for conditioning a bulk container for ultra-high purity liquefied gas. Vapor is generated in the container from a conditioning quantity of the ultra-high purity liquefied gas by imposing a temperature difference on the container so that the vapor condenses when a temperature difference is achieved. The resulting liquid reflux, e.g., the condensed liquid drips or flows back to the conditioning quantity of the liquified gas, washes or removes contaminants, e.g., particles, metal and moisture, from the interior surface of the container. A portion of the vapor is vented from the container for reclamation. The used conditioning liquid may also be reclaimed.

Abstract: For the processing of waste oil, i.e. environmentally safe processing, a process and installation are used whereby the waste oil is preheated with the distillation gases and is then distilled itself by burning the distilled waste oil. The liquid and solid residues are exposed to the flame produced by the combustion of the distilled waste oil, while the gaseous residues are heated to over 1,200.degree. C. in a long-hold chamber constructed as a fume incinerator. In order to calcine the solid or burn the liquid residues, they are collected in the distillation chamber and transported via a rotating cylinder and a chute into the combustion chamber where they are then correspondingly calcined by the burner flame. In contrast, the gaseous residues are fed to a long-hold chamber, whereby the latter is a pipe system with a length of 75 m or more.

Abstract: Sludge is removed from a reboiler while the reboiler is supplying heat to a fractionator, by using sludge removal apparatus added to the reboiler. The reboiler to which the sludge removal apparatus is added comprises an evaporative type shell and tube heat exchanger in which sludge can accumulate as a residue from evaporated liquid, and further in which unevaporated liquid is withdrawn from the reboiler as a product. Sludge removal is accomplished by drawing a relatively small liquid flush stream from the reboiler liquid product stream, pressuring the flush stream through a pump, and then recycling the flush stream to a sparger appropriately disposed in the heat exchanger shell. Sludge dislodged by the sparger is removed along with the reboiler liquid product in a flow path along the bottom surface of the shell through cut-outs provided in the lower edge of the weir and baffle plates in the reboiler which without the cut-outs would block the flow path for the sludge.

In a preferred embodiment, feed water is admitted to the boiling tank in large batches and the production of distilled water continues uninterrupted until the entire batch is distilled to conserve heat energy even if demand ceases during such batch distillation. A cleaning mode is provided to remove scale from the interior of the boiling tank with a simplified manual cleaning procedure.
