Abstract: The invention relates to a process for producing methanol and to a plant for producing methanol. A first fresh gas suitable for production of methanol and having a high carbon dioxide content is pre-compressed by a first compressor stage to obtain a second fresh gas. The second fresh gas is merged with a recycle gas stream and further compressed to synthesis pressure in a second compressor stage. Catalytic conversion of the thus obtained synthesis gas stream in a plurality of serially arranged reactor stages with intermediate condensation and separation of the crude methanol reduces the recycle gas amount in the synthesis circuit to such an extent that recycle gas may be directly recycled to the second fresh gas stream, thus ensuring that no recycle gas compressor stage is required and that the total compressor power may be reduced.

Abstract: The invention relates to a multi-strand plant and a corresponding process for producing olefins from oxygenates in which a plurality of reactor trains which each comprise one or more catalyst-containing oxygenate-to-olefin (OTO) reaction zones are arranged in parallel and operated in parallel, wherein at least one of the parallel reaction zones may be operated in a regeneration mode while the OTO synthesis reaction may be performed in the other reaction zones parallel thereto. The partial product streams obtained from the individual reactor trains operated in a synthesis mode are discharged via partial product conduits, combined into a complete product conduit using a connecting device, compressed using a compressor and separated into a plurality of olefin-containing hydrocarbon fractions using a multi-stage workup apparatus. The inventive configuration of the plant and of the process reduces pressure drops and thus enhances the yield for short-chain olefins, for example propylene.

Abstract: Systems and methods for process tending with a robot arm are presented. The system comprises a robot arm and robot arm control system mounted on a self-driving vehicle, and a server in communication with the vehicle and/or robot arm control system. The vehicle has a vehicle control system for storing a map and receiving a waypoint based on a process location provided by the server. The robot arm control system stores at programs that is executable by the robot arm. The vehicle control system autonomously navigates the vehicle to the waypoint based on the map, and the robot arm control system selects a target program from the stored programs based on the process location and/or a process identifier.

Abstract: A process for making multi-phase liquid compositions is disclosed. For example, a plurality of liquid phases can be placed in separate vessels equipped with supply lines. Predetermined amounts of each of the liquid phase can be transferred, via the supply lines, into a combiner that aligns each of the liquid phases. The liquid phases can be transferred from the combiner to a blender. A mixing element of the blender can blend the liquid phases together to produce a multi-phase liquid composition having a visually distinct pattern formed by the liquid phases. The multi-phase liquid phase composition can be transferred to an individual product container via a delivery nozzle. When said multi-phase liquid composition is transferred to said individual product container via said delivery nozzle, the individual product container can be rotated, via a rotating platform of a bottle holding device.

The method generally includes contacting a mixture comprising xylene isomers and ethylbenzene with a para-xylene selective adsorbent to obtain a para-xylene depleted raffinate, and a desorption effluent comprising a para-xylene enriched product. The method also includes isomerizing the para-xylene depleted raffinate. The contacting step is carried out in a manner such that the raffinate need not be pressurized prior to isomerization, thus advantageously obviating expensive compression steps.
