摘要:
The present invention provides a weir quench, an apparatus utilizing the weir quench and processes incorporating the same. The weir quench incorporates an inlet having an inner diameter (Di) and an upper chamber having an inner diameter (Duc), wherein the inlet inner diameter (Di) is at least 90% of the upper chamber inner diameter (Duc). The apparatus constitutes a reactor having an outlet with an inner diameter fluidly coupled with the weir quench inlet, wherein the ratio of the reactor oulet inner diameter (Dr) to the weir quench inlet diameter (Di) is greater than one. The weir quench, and apparatus are advantageously utilized in processes utilizing a limiting reagent.

A reactor and a reactor system for carrying out high temperature and high pressure reactions is disclosed herein. The reactor has an isolatable inner vessel for allowing for heat energy efficient cooling and heating of the reactor. The reactor comprises an outer reactor adapted for withstanding a reaction pressure and a reaction temperature, the outer reactor having a sealable reactor lid; an inner vessel within the outer reactor for containing a reaction solution and at least one reaction vessel, the inner vessel being open to the outer reactor such that the reaction pressure of the inner vessel and the outer reactor are substantially equalized and vapor in the inner vessel passes to the outer vessel, the inner vessel having a splatter shield for substantially preventing spillage of the reaction solution from the inner vessel into the outer reactor; a vapor injector in communication with the inner vessel for injecting vapor into the inner vessel for heating the reaction solution; an outlet in the outer vessel for exhausting vapor from the outer reactor and the inner vessel; and an outer reactor outlet for draining a liquid contained between the outer reactor and the inner vessel.

Disclosed is a reactor and agitator useful in a high pressure process for making 1-chloro-3,3,3-trifluoropropene (1233zd) from the reaction of 1,1,1,3,3-pentachloropropane (240fa) and HF, wherein the agitator includes one or more of the following design improvements: (a) double mechanical seals with an inert barrier fluid or a single seal; (b) ceramics on the rotating faces of the seal; (c) ceramics on the static faces of seal; (d) wetted o-rings constructed of spring-energized Teflon and PTFE wedge or dynamic o-ring designs; and (e) wetted metal surfaces of the agitator constructed of a corrosion resistant alloy.
摘要:
Apparatus and methods are provided for converting methane in a feed stream to acetylene. A hydrocarbon stream is introduced into a supersonic reactor and pyrolyzed to convert at least a portion of the methane to acetylene. The reactor effluent stream may be treated to convert acetylene to another hydrocarbon process.
摘要:
The invention relates to a reactor for gasifying and/or cleaning a starting material (12), especially for depolymerizing plastic material (12), which reactor comprises: a reactor vessel (14) for receiving the starting material (12), especially the plastic material (12); a metal bath (26) which is arranged in the reactor vessel (14) and includes a liquid metallic material having a metal bath melting temperature (T Schmelz ); a plurality of filling elements (25) which are at least partially arranged in the metal bath (26); and a heater, especially an induction heater (18) for heating the starting material (12) in the reactor vessel (14). According to the invention, a metal bath intermediate storage device (52) is provided and is connected to the reactor vessel (14) and is designed to remove at least part of the metal bath (26) from the reactor vessel (14) and to return the metal bath (26) to the reactor vessel (14), and comprises a delivery device (64) for delivering the metal bath (26), the delivery device (64) having a pressure increasing unit (60) by means of which the metal bath (26) can be delivered by applying the gas pressure (p).
