摘要:
A process for isolating liquid urea and its thermal decomposition products from the off-gas of melamine synthesis, which gas has been freed from melamine by fractional condensation and then been washed with molten urea, wherein the off-gas, containing 2-10 kg of melt per kg of pure gas, is passed at 8-30 m/sec tangentially into the upper part of an axially symmetrical separation zone. As a result of the rotation imparted to the gas/liquid mixture, the two phases are separated from one another, and both pass downward through the separation zone. The gas and liquid are separately taken off at the bottom end of the separation zone. The residence time of the gas mixture in the separation zone is not less than 0.5 second.

A system and method for facilitating mentoring in an enterprise. An example method includes establishing a set of candidate mentors and a set of candidate mentees; providing a first user option to match a candidate mentor with a candidate mentee from the set of candidate mentors and the set of candidate mentees, respectively, yielding a mentor and an associated mentee in response thereto; selectively tracking a first performance parameter of the mentee over an interval during which a mentoring relationship exists between the mentor and the mentee and providing an indication of a change in the first performance parameter over time; and providing a second user option to initiate an action in response to the indication. The action may include initiating an adjustment in compensation for the mentee or mentor when the indication indicates a particular improvement in one or more performance parameter(s).

A continuous closed-system process for the environmentally friendly drying and purification of benzanthrone which comprises the steps of charging a benzanthrone-containing paste of pumpable consistency onto a melt held in a stirred kettle, dewatering and melting the paste by means of steam, condensing the water vapor emerging from the stirred kettle, flaking the melt from the stirred kettle by means of a rotating drum, and packaging the flaked solids.
摘要:
The invention relates to a process for rapidly letting-down the pressure in continuous high pressure polymerization systems for the polymerization of ethylene. In this process, the let-down hot reaction mixture is passed into an expansion vessel in such a way that the jet of let-down hot reaction mixture issuing from the let-down line is led into the partially water-filled expansion vessel at an angle of from 0.degree. to 45.degree. to the water surface, so that the jet does not enter below the surface but must touch or strike it. The method described makes it possible to let the mixture down partially and thus to slow down the decomposition in the case of explosive decomposition reactions occurring in the polymerization system.

摘要:
A system and method for providing career-related information. An example method includes acquiring user information, wherein the user information includes an indication of a target career position or opportunity; obtaining aggregated information pertaining to workers who have attained the target career position; and employing the user information and the aggregated information to provide career-related information pertaining to one or more career paths. In the example method, a user questionnaire is employed to facilitate acquiring the user information. The step of obtaining aggregated information includes collecting anonymous information from profiles of the workers. The profile information may be retrieved from a Human Capital Management (HCM), performance management system, social network system, or other Enterprise Resource Planning (ERP) system component of an organization.

摘要:
The invention relates to a process for preparing an aqueous powder coating dispersion, which comprises introducing a liquid melt comprising binders and crosslinking agents and also, if desired, catalysts, auxiliaries and further additives such as devolatilizers, UV absorbers, free-radical scavengers and/or antioxidants into an emulsifying apparatus, preferably with the addition of water and stabilizers, and cooling and filtering the resultant emulsion.
摘要:
A process for separating a liquid eutectic mixture by crystallization of one eutectic forming substance of the mixture on a cold surface to which seed crystals of the eutectic forming substance have been applied in the form of a seed crystal layer, and subsequent removal of the eutectic forming substance in liquid form after heating of the surface.
摘要:
Ethylene/.alpha.-olefin copolymers are prepared by catalytic dry-phase copolymerization of the monomers in a stirred or fluidized polymerization zone, transfer of the resulting mixture of solid copolymer and unconverted gaseous monomer into a let-down zone and separation of the mixture, after pressure reduction, into a gaseous phase and a solid phase, by a continuous process in which the solid phase is continuously flushed beforehand with gaseous ethylene and then flushed with a mixture of nitrogen and steam. The ethylene copolymers are very substantially free of residual monomers and odor and flavor substances.
