Abstract: A gas-phase polymerization system and a solids recovery system for a fluidized bed reactor. The fluidized bed reactor can include a fluidizing gas outlet from which a discharged mixture of fluidizing gas and polymer fines is released, and a cyclone separator can separate the polymer fines from the fluidizing gas for reentry into the fluidized bed reactor. It has been found that by situating the reactor entry nozzle of the fines return line which is closest to the gas-phase reaction zone significantly higher in the reaction zone than in a conventional fines return line, and by directionally orientating the incoming stream of polymer fines and carrier gas into the fluidized bed in the reaction zone, a significant increase in the residence time of the particle in the reaction and larger particles which meet a product size distribution specifications are achieved.

Abstract: A method for providing information based on geographic parameters is disclosed. The method includes providing a map. A user-defined position on the map is received. Data of a first type, wherein the first type data relates to the user-defined position on the map, is provided.

Abstract: A method for providing economic information based on geographic parameters that includes providing a map for display on a device, receiving a user-defined area on the map, and providing data relating to the user-defined area. Obtaining the relevant information or data about a particular geographic region frequently involves consulting a plurality of sources. The current method is much more efficient and cost effective to retrieve from fewer sources and provide the information in a quick and easy to comprehend format.
