One aspect of the present disclosure provides a system for producing 1,3-butadiene, which includes: a first supply unit, by which a first feed including a butene raw material, oxygen and steam is supplied; a second supply unit, by which a second feed including a butene raw material and oxygen is supplied; and a reaction unit, which includes a catalyst fixed bed and in which an oxidative dehydrogenation reaction takes place, wherein the first supply unit is connected to a front end of the reaction unit, and the second supply unit is connected to an intermediate end of the reaction unit.

The present invention is a combustion strategy using a swirl burner tip, which is one of stoichiometric mixture of reactants (2H.sub.2+O.sub.2.fwdarw.2H.sub.2O) with added high quality dry steam (H.sub.2O (g)) as a thermal diluent. The amount of dry steam can be determined by the safety requirements of the reactants and the desired temperature of post-flame gases. It can be appreciated that the design of the swirl burner tip is for safe handling of the reactants, and for rapid and thorough mixing of the reactants so combustion occurs in a nearly premixed configuration exterior of the swirl burner tip. The H.sub.2/O.sub.2 ratio is fixed to consume all H.sub.2 and O.sub.2 (stoichiometric), with dry steam (H.sub.2O (g)) strategically added to the reactants. The burner tip is configured to create counter swirling reactant flows separate from each other.

A processing system for producing a product material from a liquid mixture includes an array of one or more power jet modules adapted to jet the liquid mixture into one or more streams of droplets and force the one or more streams of droplets into the processing system, a dispersion chamber and a reaction chamber adapted to process the one or more streams of droplets into the product material. A method for producing a product material from a liquid mixture on a processing system includes moving each of the one or more power jet modules and be connected to an opening of a dispersion chamber opening one or more doors of the one or more power jet modules, processing the one or more streams of droplets inside a reaction chamber, closing the one or more doors of the power jets modules and moving each of the one or more power jet modules in a second direction.

A method and system for rapidly preparing lithium carbonate or concentrated brine using high-temperature steam. The method comprises the steps of: feeding brine into a reactor, heating the brine with high-temperature steam above 200° C. while simultaneously discharging steam produced in the reactor, cooling and condensing the discharged steam in a condenser and collecting the condensate, and stopping the high-temperature steam after the brine is concentrated to a predetermined concentration or after a sufficient amount of lithium carbonate is collected. The system comprises: a reactor provided with a brine inlet, a steam outlet connected to a condenser, a product outlet, and a plurality of steam pipes. The method concerns the direct heating of brine using high-temperature steam, which is effective and efficient, and also produces fresh water. The heating is uniform and rapid, and does not require jackets, heat exchange tubes, mixers and vacuum pumps, vastly simplifying the system.
