Disclosed herein are a method and systems for cumene hydroperoxide cleavage with an improved configuration for online instrumentation. The systems comprise a first fluid loop comprising one or more reactors and a fluid pump and a second fluid loop in fluid communication with the first fluid loop. This second fluid loop comprises an instrument configured to measure a characteristic of a fluid flowing through the second loop, wherein an input of the second fluid loop is disposed downstream of said fluid pump and an output of the second fluid loop is disposed upstream of said fluid pump. The method comprises causing fluid to flow within a first stage comprising one or more reactors and a fluid pump, wherein the first stage is configured to decompose a cumene hydroperoxide in the presence of a catalyst mixture to form a dicumyl peroxide mixture. The method also comprises causing at least a portion of the fluid to flow through a instrumentation line in open fluid communication with the first stage. This instrumentation line comprises an instrument configured to measure a characteristic of the fluid flowing through the instrumentation line and an input of the instrument line is disposed downstream of said fluid pump.

Continuous photochemical production of high purity linear mercaptan and sulfide-containing compositions.

An isomerization method consists of a deisobutanizer column receives feed comprising n-butane. The deisobutanizer column delivers its bottoms a portion to a reboiler and another portion along with hydrogen is routed to a isomerization reactor and the reactor effluent is returned to the column. A stabilizer which is integrated with the column, an overhead stream used as a reflux and bottoms containing an iso-butane-rich stream that is the iso-butane product stream. The column overhead effluent is routed to separator, which splits the hydrocarbons and effluent, where the hydrocarbons are routed to deisobutanizer column and effluent recycled to stabilizer, where the stabilizer separates the reactor effluent into product streams contains an iso-butane product stream, a n-butane product stream, and a lighter hydrocarbon product stream.

The present invention relates to a process for the preparation of an alkanesulfonic acid by oxidation of a sulfur containing starting compound with an oxygen containing fluid, wherein the sulfur containing starting compound is provided in a reaction system, comprising a reaction vessel (1) with an expansion vessel (2) on its top, wherein the reaction vessel and the expansion vessel are connected to allow a flow of a fluid stream from the reaction vessel into the expansion vessel.

The disclosure, in one aspect, relates to methods of preparing a CHA zeolite under ambient pressure conditions. In further aspects, the disclosure relates to methods such that a mother liquor can be isolated from a disclosed method, and recycled for use in a disclosed method for further preparation of a CHA zeolite. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

The present invention discloses a hydrogen sulfide reactor vessel with an external heating system that is conductively and removably attached to an exterior portion of the reactor vessel. Also disclosed are processes for producing hydrogen sulfide utilizing the reactor vessel.

A reaction apparatus used for a continuous reaction process for the preparation of trifluoroethane includes a housing, a rotary cutting component, a submersible pump and a flow deflector. The flow deflector includes two sets of flow-deflecting plates, each set of said flow-deflecting plates including a plurality of flow-deflecting plates. Two sets of flow-deflecting plates are fixed to each of the two opposing side walls, and the two adjacent flow-deflecting plates are in offset alignment. The submersible pump is arranged inside the reaction chamber body. A liquid inlet line can connect a directly to the submersible pump without requiring the arrangement of an additional pipeline.
