Abstract: A method for treating polluted material such as industrial waste water or polluted water from other sources, sewage or sewage sludge, or other forms of sludge, to degrade oxidizable substances therein. The polluted material is subjected to a wet oxidation process in a tubular reactor so as to decompose and/or modify oxidizable substances therein and improve the filterability of any solids present in the material. The material may also be pretreated to facilitate the wet oxidation process. Solid polluted material is preferably in the form of an aqueous suspension when subjected to wet oxidation. The wet oxidation process is performed to such an extent that the decomposed and/or modified substances remaining after the oxidation step are substantially biodegradable. Heavy metals may also be removed subsequent to the wet oxidation process.

Abstract: A vacuum valve for use in a tanker is constructed with means (11, 12, 13, 33, 35, 36) for applying a supplemental closing force to the valve body if the pressure drop across the vacuum valve rises substantially above a value designated for the vacuum valve. Such an extraordinary rise of the pressure drop will occur by escapage from an injury under the waterline caused by grounding, and the supplemental closing force will therefore close the valve very fast and will thereby contribute to maintaining a high vacuum in the tank, counteracting continued escape.

Abstract: A vacuum valve for use in a tanker is constructed with means for releasing a supplemental force on the valve body if the pressure drop across the vacuum valve rises substantially above a value designated for the vacuum valve. Such an extraordinary rise of the pressure drop will occur by escape from an injury under the water-line caused by grounding, and the supplemental closing froce will therefore close the valve very fast and will thereby contribute to maintaing a high vacuum in the tank, counteracting continued escape.

Abstract: A pressure relief valve for pressure equalization between a closed space and the surrounding atmosphere comprises a valve housing (1) with an upwardly facing blow-off opening (11) in which a conical valve seat (13) is formed. A drop-shaped body (14) arranged in the blow-off opening (11) is formed on its underside with a conical valve surface (15) co-operating with the valve seat (13). The drop-shaped body is connected with a lifting disc (21) which has a larger area than the valve seat (13) and is surrounded by a free passage slot (22). By suitable dimensioning, advantageous characteristics can be obtained for pressure and blow-off velocity as functions of the blow-off quantity, and the blow-off will always take place in the form of a jet which by means of the drop-shaped body (14) is directed vertically upwards at high velocity.

Abstract: A method for treating polluted material such as industrial waste water or polluted water from other sources, sewage or sewage sludge or other forms of sludge, or polluted soil, to degrade oxidizable substances therein, comprising subjecting the polluted material to a wet oxidation process in a reactor so as to decompose and/or modify oxidizable substances therein and optionally improve the filterability of solids when present in the material; the material may optionally be pretreated so as to facilitate the wet oxidation process. Solid polluted material is preferably in the form of a liquid suspension, such as an aqueous suspension, when subjected to wet oxidation. The wet oxidation process is performed to such an extent, optionally with subsequent substantial removal of heavy metals, that the decomposed and/or modified substances remaining after the wet oxidation and the optional removal of heavy metals are substantially biodegradable.
