1.WO/1991/017956PRODUCTION OF ACID SOLUBLE TITANIA

WO - 28.11.1991

国际分类 C01G 23/047 申请号 PCT/AU1990/000217 申请人 WIMMERA INDUSTRIAL MINERALS PTY. LTD. 发明人 HOLLITT, Michael, John

The specification discloses a method of making acid digestible titania. The method comprises the steps of: (1) adding a magnesium or manganese compound to a titaniferous mineral if the content of manganese and magnesium in the mineral is insufficient; (2) heating the mineral in the presence of a reductant for a sufficient length of time and at a sufficiently high temperature to permit the reduction of iron containing compounds to metallic iron and enable titania present to convert to an acid digestible form; (3) cooling the mineral; and (4) separating iron from the mineral by means of an aqueous aeration step. The titaniferous mineral contains insufficient magnesium and manganese if the following expression is not satisfied: (1.98a + 1.14b)/d » 0.08, where a represents the percentage by weight of MgO contained in the mineral, b represents the percentage by weight of MnO contained in the mineral; and d represents the percentage by weight of TiO₂ contained in the mineral. The magnesium or manganese compound is either an oxide or a compound that is capable of converting to an oxide under reaction conditions. An aqueous aeration technique described in the specification involves the use of a sequesterant that is capable of sequestering iron from the mineral without significantly lowering the local pH while at the same time permitting the formation of an oxide of iron at a point away from the mineral. An example of such a sequesterant is citric acid.

The method allows the building of houses of any size in conformity with anti-seismic and anti-cyclonic regulations, particularly in regions subjected to hurricanes.

4.WO/1995/018268TENSIONED RISER COMPLIANT TOWER

WO - 06.07.1995

国际分类 E02B 17/02 申请号 PCT/EP1994/004345 申请人 SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ B.V. 发明人 HUETE, David, Armstrong

A tensioned riser deepwater platform suitable for offshore oil and gas applications is disclosed having a foundation (16) secured to the ocean floor, a topside facility above the ocean surface, and a vertically extending tower jacket (12) secured to the foundation and supporting the topside facility. A plurality of substantially vertically extending risers provide fluid communication between the wells and the topside facility. These risers are connected to riser supports near their upper ends and the riser supports provide the pricipal load transfer between the risers and the tower jacket. Thus, the conductor guides and attendant horizontal bracing of conventional deepwater design can be substantially eliminated.
