Abstract: An apparatus and method for delivery of additives(s), e.g., catalyst, co-catalyst, scavengers, and/or other reaction- or product-modifying agents, to a reaction or mixing site, such as a reaction vessel, offers the capability for multi-additive delivery and customization of additive selection, flow and flow rate, and if desired, mixing thereof, without production train shutdowns. The invention includes at least two additive sources that are detachably connected, with conduit, to the reaction or mixing site, and a process control means, preferably automated, that is capable of initiating, terminating, and determining the rate of flow from the additive sources.

Abstract: Disclosed is a method for carrying out a chemical reaction in a reactor, at least one substance is present in a container that is closed in a gas-tight manner, is introduced into the reactor in said container and is released by breaking open the container. The container is designed such that it breaks open when a specified bursting pressure difference between the internal pressure and external pressure is exceeded. The container is broken open and the substance located in the container is thus released as a result of deliberate application in the reactor of a pressure difference exceeding the bursting pressure difference.

Abstract: An integrated process for the synthesis of urea and melamine, wherein: urea is synthesized with a stripping process in a high-pressure synthesis loop comprising a reactor, a stripper and a carbamate condenser, and the urea solution leaving said stripper is sent to a recovery section to produce a concentrated urea product and a recovered carbamate solution; at least part of said urea product is converted to melamine, and the off-gas from the synthesis of melamine are recycled to the urea synthesis by mixing with the gas phase from the stripper and with said recovered carbamate solution, thus forming a mixed flow which is then condensed in said carbamate condenser, and the condensate is eventually directed to the reactor.

Abstract: A precision volumetric liquid dispensing instrument is disclosed that includes two pressure sensors and a fluid passageway with a defined volume portion in communication with the two sensors for receiving and distributing liquid in relatively small volumes. One of the pressure sensors is positioned to measure pressure at one portion of the defined volume portion of the fluid passageway and the other of the gas pressure sensors is positioned to measure gas pressure at a different portion of the defined volume portion of the passageway. At least one valve is in communication with the passageway for moving fluids into or out of the defined volume portion of the fluid passageway, and a processor carries out a step selected from the group consisting of (i) calculating the volume of the liquid based upon the measured pressure and (ii) metering a liquid into the defined volume portion of the fluid passageway until the measured pressure indicates that a desired volume of fluid is in the fluid passageway.
