摘要： A self-cleaning magnetic filter for removing ferrous contaminates from a natural gas process stream including a housing through which the process stream follows for removing ferrous contaminates in the process stream by magnetic attraction with a plurality of magnetic bars that are removably disposed in a plurality of non-magnetic sleeves disposed within the housing. A recirculating washing solution is used to flush contaminates that adhere to the exterior surfaces of the non-magnetic sleeves and from the housing. A bag filter is used to remove contaminates from the washing solution to allow recycling the washing solution.

摘要： A waste management system for plastic or other material floating on the surface and in the subsurface of a body of water. A shredding device will reduce the size of the particles of waste. Ocean water is removed by a drying device. The dried waste material is frozen to a temperature at or below minus fifty degrees Fahrenheit, using liquid nitrogen or other suitable means. The frozen waste material is then pulverized and ground into a powder. The powder may then be sprayed into a gas-filled chamber and heated. Temperature, pressure and humidity are maintained within the chamber for more than one minute. Microwave or other radiation and catalysts may be used to enhance the process of extraction. The processed material is then removed from the chamber. Carbon may be recycled or used as fuel by the ship. Water may be used by the ship or returned to the ocean.

摘要： A system and method directed to the economical recovery of valuable iron constituents from iron blast furnace and steel-making slag fines wherein the slag is obtained and subjected to a series of classification steps which progressively sort the slag fines by various physical characteristics, including magnetism, size, and density, into relatively iron-rich and relatively iron-poor classifications, resulting in the isolation of iron-rich commercial byproduct at one or more of the classification steps.
