Abstract: Purification of liquefied coal using a centrifugal filter and drying at least a part of the filter cake with a gas is improved in that the filtering aid used in this process is recovered from the filter cake (together with coarse particles of the non-liquefied residue) and re-used. The recovery of the filtering aid is carried out on a screening appts. of a wind sifter; or by extraction, or by magnetic sepn. (if a magnetic filtering aid is used e.g. iron or nickel granules. The pref. filtering aids are inorganic, water-soluble salts, such as, sulphates, chlorides, bromides, borates, silicates and carbonates, or oxides. The salts can be recovered by extraction with water. By this method, the filtering aid can be economically recovered and re-used (in the conventional process, the filter cake is discarded together with the filtering aid contained therein).

Patent DE-2656513-A1 (DE)
Inventor: WALTER HEINZ ING GRAD
IPC: F16L3/00
Filed: 1976-12-14
Abstract: In order to avoid damage to components due to whiplashing pipe ends in the event of a pipe break, the pipelines in nuclear power stations have pipeline securing systems which are constructed as steel frames and are anchored in a concrete wall. In order that the forces to be absorbed by the steel frame (3) are not introduced into the concrete wall (10) without being damped, it is not directly mounted on the concrete wall. Rather, it is connected to two steel girders (9) which are anchored in the concrete wall on supports (11) and via mounting elements (12). The steel girders (9) are designed in this case such that they absorb the forces acting on the steel frame through the work of deformation. <IMAGE>

Title: Purification of pyrolysis gas - by oil scrubbing and contact with sorbent above dew point
Inventor: HOELTER HEINZ
IPC: F23G5/027
Filed: 1977-01-01
Abstract: Purificn. of pyrolysis gas (esp. from a refuse pyrolysis plant) is carried out by first scrubbing the gas and cooling it to a temp. above the dew point by contact with a wash oil. The gas is then passed through a packed bed of sorbent to remove residual contaminants, and is then burned in the combustion section of the pyrolysis reactor.

Title: Continuous washer for non-filterable hydroxide precipitates - having initial mixing zone with subsequent horizontal settling zone
Inventor: MARDERSTEIG HANS-GEORG DIPL CH
IPC: B01D11/02
Filed: 1977-03-02
Abstract: Pptes. which are difficult to filter are washed in continuous process with final sepn. of suspension and wash liquor. The suspension is the heavy phase and the wash liquor the light phase, both being intensively mixed. The agitated mixture is then fed along a horizontal settling zone to allow sedimentation. By means of the flow and of gravity the heavier phase collects and is subjected to a horizontal motion. The two phases are sepd. at the end of this horizontal zone. The sepd. heavy phase can then be recontacted with more of the lighter phase in a series of contactors arranged in series giving repeated mixing and sedimentation processes. For use in washing gelatinous pptes. of metal hydroxides esp. Ni(OH)2 and Cd(OH)2. Gives a process for washing any such aq. suspensions in a quasi counter current wash which is economical in water usage and low in energy usage. Such materials cannot be washed on filters because they rapidly clog them.
