Abstract: Solid wastes, and wastes to be compacted, are pretreated for introduction into underground salt cavities or salt caverns via a downpipe under the force of gravity by a process in which solid, uncomminuted or comminuted or finely divided to very finely divided wastes are mixed with waste sludges in a ratio such that a material results from which moldings are produced, with or without the addition of a binder, in the form of granules, agglomerates or pellets by a granulation method, or in the form of flakes by a pressing method, the flakes being comminuted to give small moldings, and, if appropriate, the moldings are surface-dried or dried completely, the moldings which are free-flowing under the force of gravity are then trickled into the salt cavity or into the salt cavern and form a pile therein until the said cavity or cavern is substantially full, and, if required, the salt cavity or the salt cavern is closed.

Abstract: Oil polluted water or solid adsorbents are treated with microbially produced glycolipids to separate the oil phase. The treatment may be carried out in an apparatus which can be taken to the site and which comprises a mixing vessel supported by an undercarriage and provided with a storage container to supply the glycolipids, filling means, overflow discharge means and outlet means at its base.

Abstract: Oils or petroleum hydrocarbons are separated from solid or solid/liquid mixtures thereof with soil, sand or oil processing residues, by treating these oil-containing mixtures with an aqueous solution or dispersion of a crude extract of microbially produced glycolipids and separating the oil-containing phase from the aqueous phase.

Abstract: A process and installation for the flooding of petroleum deposits and oil shale and, more particularly, through the use of dispersions of non-ionogenic, boundary surface-active materials in water as the flooding medium. For the flooding of petroleum-hydrocarbon materials from petroleum deposits and oil shale there can be utilized dispersions of non-ionogenic, boundary surface-active glycolipids, and such preferred structures can be employed which are produced from hydrocarbon mixtures as the C-source. This is effected in two stages with predetermined technological measures. In the first stage, there are initially produced glycolipids through microorganisms with alkane mixtures under predetermined parameters in semi- or continual process cycles and, in the second stage, separated from the cellular material through temperature, pH, osmotic shock. The formed glycolipids can also be separated from the cellular material with unpolarized, organic solvent media.

Abstract: A device for displacing the walking beam of deep-well pump drives. The walking beam support of the pivot bearing has on its long sides guides for the walking beam, while its narrow sides have slide arrangements for slightly raising and supporting the walking beam during lengthwise displacement. A two-way shifting device is hinged to the pivot bearing. The other end of the shifting device is connected to that part of the walking beam which engages the crank. On both long sides of the walking beam support, a guide rail may protrude beyond the contact plane of the walking beam support and enclose the lower part of the walking beam. The narrow sides of the walking beam support may mount rollers whose axes run parallel to the narrow sides of the walking beam support. The bottom side of the walking beam has arc-shaped recesses for receiving the roller parts protruding beyond the contact area of the walking beam support. The center axes of these recesses are parallel to the rotary axes of the rollers.

Abstract: A method for the recovery of crude petroleum from mineral oil deposits, utilizing hot water flooding or alkali containing hot water flooding is described.

Abstract: Green petroleum coke is indirectly dried, than calcined in a cylindrical rotary kiln and indirectly cooled utilizing a one-way gas flow in the system. Most of the dust in the vapor from the drying step is directly burned in a steam boiler whose off-gases are used to heat the dryer. Any residual dust in the gas is collected in an electro-filter. This dust together with dust which settles out from the dryer and the kiln is collected and added in controlled amounts to the dried coke before calcining. Hydrocarbons expelled during calcining are partially burned off with a stream of secondary air introduced at the coke exit end of the kiln. Most of the remaining hydrocarbons are burned off before they leave the coke inlet end of the kiln. The calcined coke product contains 0.1% by weight of hydrocarbons. The final off-gas from the process has a residual dust content of less than 100 mg/nm.sup.3.
