Abstract: A continuous process for producing a polyurea concentrate or powder. The process includes combing at least one amine and an isocayante in the presence of a liquid diluent or a base oil in a rotor stator mixer. The concentrate comprises a polyurea in a base oil wherein the concentration of from about 20 weight percent to about 50, or 40 or 35 or 30 weight percent of polyurea based on total weight of grease thickener. The powder has particle size of 2 to 400 microns. This concentrate or powder can then be formulated by grease manufacturers to the desired final properties without the need for handling of the isocyanate and amine raw materials.

Abstract: A process and an apparatus (100) for producing a superheated working fluid from a concentrating solar plant. More specifically, the process and apparatus produce superheated steam. The apparatus is designed such that it can use more than one heat transfer medium to produce the superheated working fluid. A first heat exchanger system (101) is designed to use the heat of a first heat transfer medium in order to preheat, evaporate and superheat a working fluid in a power generating working cycle (103). A second heat exchanger system (102) is designed to use the heat of a second heat transfer medium to superheat the working fluid in cycle (103).

Abstract: Novel sulfur-containing compositions comprise a polyether polysulfide or an ether polysulfide. The polyether polysulfide may be based upon an alkoxylate (an alcohol or glycol-initiated compound) that is a copolymer of at least two of ethylene oxide, propylene oxide and butylene oxide. The polyether polysulfide may alternatively be based upon a homopolymer of ethylene oxide, propylene oxide or butylene oxide. The ether polysulfide may be based upon a methoxy-capped polyglycol or an alkyl ether of 1,3-dichloro-2-propanol.

Abstract: Water and organic low-boiling constituents in organic heat transfer fluids used to heat commercial processes are removed by introducing a gas such as nitrogen into a turbulent flow of the heat transfer fluid and separating gas which then contains low-boiling constituents from the heat transfer fluid of the heat transfer system. The gas containing low-boiling constituents may be sent to a condenser to return heat transfer fluid which also vaporizes into the gas, but to a lesser extent than the low-boilers, to the heat transfer system. The gas containing low-boiling constituents is then combusted.

Abstract: Water and organic low-boiling constituents in a organic heat transfer fluids used to heat commercial processes are removed by counter current stripping the fluid with a gas such as nitrogen. The gas containing low-boiling constituents is sent to a rectification column and condenser to return heat transfer fluid which also vaporizes into the gas, but to a lesser extent than the low-boilers, to the heat transfer system.
