Techniques for converting carbonate material to carbon monoxide include transferring heat and at least one feed stream that includes a carbonate material and at least one of hydrogen, oxygen, water, or a hydrocarbon, into an integrated calcination and syngas production system that includes a syngas generating calciner (SGC) reactor; calcining the carbonate material to produce a carbon dioxide product and a solid oxide product; initiating a syngas production reaction; producing, from the syngas production reaction, at least one syngas product that includes at least one of a carbon monoxide product, a water product or a hydrogen product; and transferring at least one of the solid oxide product or the at least one syngas product out of the SGC reactor.

A process for separating and upgrading a hydrocarbon feed includes passing the hydrocarbon feed to a distillation unit to separate it into at least a naphtha stream and a residue, passing the naphtha stream to a NHT that hydrotreats the naphtha stream to produce a hydrotreated naphtha, passing the hydrotreated naphtha to a NREF that reforms the hydrotreated naphtha to produce a reformate, passing the reformate to an ARC that processes the reformate to produce at least one aromatic product effluent and an aromatic bottoms stream, passing at least a portion of the residue to a residue hydroprocessing unit that hydroprocesses the portion of the residue to produce a hydroprocessed effluent, and passing a portion of the aromatic bottoms stream to the residue hydroprocessing unit to increase the solubility of the asphaltene compounds and reduce sedimentation. Systems for conducting the process are also disclosed.

A sparge for use in a high-pressure vessel operated at elevated temperatures and having high energy agitators for suspending mineral containing particles in a slurry. The sparge injects reagent fluids into the slurry to reduce reaction times and for controlling process parameters for extracting valuable minerals from the particles. The sparge has a vapor lock to inhibit the flow of particulate material and detritus material under low or no fluid flow situations which occur commonly in the operation of high pressure autoclaves. The sparge has a fluid flow path that increases in cross-sectional area in the direction of flow of reagent fluids so as to keep reagent fluids flowing at a velocity below a critical impingement velocity that can cause metal materials of the sparge to either wear rapidly, combust and in the worst case lead to loss of containment and violent and rapid depressurization of the high pressure vessel.

A catalytic membrane composite that includes porous supported catalyst particles durably enmeshed in a porous fibrillated polymer membrane is provided. The porous fibrillated polymer membrane may be manipulated to take the form of a tube, disc, or diced tape and used in multiphase reaction systems. The supported catalyst particles are composed of at least one finely divided metal catalyst dispersed on a porous support substrate. High catalytic activity is gained by the effective fine dispersion of the finely divided metal catalyst such that the metal catalyst covers the support substrate and/or is interspersed in the pores of the support substrate. In some embodiments, the catalytic membrane composite may be introduced to a stirred tank autoclave reactor system, a continuous flow reactor system, or a Parr Shaker reaction system and used to effect the catalytic reaction.

A flow splitter may include an inlet, at least two outlets, and an internal vane comprising a first end corresponding to the inlet and a second end corresponding to the at least two outlets, wherein the internal vane is configured to turn, between the first end and the second end, an internal flowing fluid from 0 degrees to a degree between about 60 degrees and 150 degrees. Methods of dividing fluid flow are also provided.
