1.WO/1989/009365METHOD AND APPARATUS FOR STRIPPING VOLATILE ORGANIC COMPOUNDS FROM SOLID MATERIALS

WO - 05.10.1989

Класс МПК B09C 1/06 № заявки PCT/US1989/001029 Заявитель KEATING ENVIRONMENTAL SERVICE, INC. Изобретатель KEATING, Paul, J., II

Apparatus, and a method for using the apparatus, for stripping solid material containing at least one volatile organic compound (VOC). The apparatus is provided with a dryer (12) having a heat source to heat the VOC-containing material to a first temperature, hot enough to volatilize the VOC, but below the cracking temperature of the VOC. The VOC in the dryer is volatilized to form VOC gases. A means for combusting the VOC gases (e.g. a kiln) (14) heats the VOC gases with excess air to a second temperature, hot enough to destroy the organics in the VOC gases. Simultaneously the combustion means preferably can be used to treat a kiln processable material to form a desired product. The kiln includes means for feeding the kiln processable material to the heating chamber, means (21) for cooling and recovering the desired product, the means (16) for providing heat for the VOC dryer. The apparatus also includes a conduit (15) for conducting the gases containing VOC from the dryer to the kiln.

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

WO - 28.11.1991

Класс МПК C01G 23/047 № заявки PCT/AU1990/000217 Заявитель WIMMERA INDUSTRIAL MINERALS PTY. LTD. Изобретатель 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.

4.WO/1995/018268TENSIONED RISER COMPLIANT TOWER

WO - 06.07.1995

Класс МПК E02B 17/02 № заявки PCT/EP1994/004345 Заявитель SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ B.V. Изобретатель 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.
