An improved process for the recovery of high-purity ethylene-oxide water feed streams to EO purification and MEG reaction units when both are operating in EO plants that incorporate EO Stripper bypass technology, by installing a second lights stripper to exclusively degasify the diluted EO feed to the MEG reactor, thus permitting the use of additional bypassed (gasified) EO absorbate as the diluent and resulting in a substantial increase in the total amount of EO absorbate that can bypass the EO Stripper.

A hydrocarbon-forming gas compression method comprising: a hydrate formation step in which water and hydrate-forming gas are mixed at a first pressure and a first temperature, resulting in the formation of hydrate; a decomposition step in which the hydrate is warmed, and the hydrate is decomposed to re-generate hydrate-forming gas at a second pressure higher than the first pressure.

Method and system for the extraction of oils from a biomass with a liquid carbon dioxide using cosolvent. The system and method can be used to extract cannabinoids from Cannabis biomass by cryogenically freezing the biomass and exposing the Cannabis biomass to sub-cooled liquid carbon dioxide and capturing a first high-terpene extract fraction, and then exposing the Cannabis biomass with a mixture of superfluid carbon dioxide and a cosolvent to capture a high cannabinoid second fraction.

Disclosed is a recycling apparatus for a cross-linked polyethylene resin using a twin screw extruder. The recycling apparatus for a cross-linked polyethylene resin using a twin screw extruder according to an embodiment of the present disclosure includes: a raw material supply unit configured to supply a raw material that is a cross-linked polyethylene resin; and a twin screw extruder configured to receive the raw material from the raw material supply unit, the twin screw extruder including a cylinder and a twin screw installed inside the cylinder to rotate in the same direction, the twin screw extruder being configured to de-crosslink and recycle the raw material under a de-crosslinking reaction temperature and reaction pressure atmosphere while continuously transporting the raw material along the twin screw by the rotation of the twin screw.

This invention relates to a robotic device 10.1, 10.2 and method for handling catalyst material 106, 206 in a reactor 100 by removing spent catalyst from the reactor and/or loading the reactor with fresh catalyst without an operator having to enter an interior of the reactor which increases operator safety. The robotic device includes a body 12, which is configured to engage a flange 104 of the reactor, and a handling arm which is configured for use both as a cleaning arm 18 and a loading arm 218. The handling arm is connected to the body and is angularly and longitudinally displaceable relative to the body. The handling arm has a segment which is telescopically extendible/retractable relative to the body. When used as a cleaning arm, the arm receives a vacuum line for removing catalyst. When used as a loading arm, a telescopic loading sleeve is connected to the segment.
