Abstract: A water-based coil coating without amine neutralization includes the following components in percent by weight: an amine-free waterborne resin: 88-93%, a crosslinking resin: 4-9%, a first auxiliary: 0.5%, a second auxiliary: 0.5%, a third auxiliary: 2.0%, and a diluent. A solid content in the water-based coil coating is greater than 40%. A solid content ratio of the amine-free waterborne resin to the crosslinking resin is in a range of 4-9. The water-based coil coating does not include amine neutralizing agents, not only possesses performance equivalent to or even exceeding that of oil-based coatings, but also greatly reduces VOC emissions, allowing for direct exhaust of tail gases. Wastewater treatment is extremely simple, and there is no pollution from ammonia nitrogen and nitrogen oxides. Downstream coating enterprises have a very high acceptance of the water-based coil coating without the amine neutralization.

Abstract: Techniques for processing residuum include receiving a feed stream that includes a residuum hydrocarbon fraction at an ebullated bed hydroconversion reactor; contacting the residuum hydrocarbon fraction with hydrogen and a hydroconversion catalyst in the ebullated bed hydroconversion reactor to produce a partially converted reactor effluent product; separating, in a first separation zone, the partially converted reactor effluent product into a distillate stream and a heavy hydrocarbon stream; feeding the distillate stream to a bottom portion of an integrated hydrocracking/hydrofinishing reactor; and feeding the heavy hydrocarbon stream to a top portion of the hydrofinishing reactor.

Abstract: A method of forming C6-C8 aromatics may include selectively dealkylating a Fluid Catalytic Cracking (FCC) heavy cut naphtha that has at least C9+ aromatics to selectively crack C2+ alkyl chains from the C9+ aromatics, thereby forming the C6-C8 aromatics. The selectively de-alkylated heavy cut naphtha is then combined with a FCC middle cut naphtha, and aromatics including the C6-C8 aromatics are separated from the combined stream. A system for forming C6-C8 aromatics may include a fluid catalytic cracking unit for producing a FCC heavy cut naphtha comprising at least C9+ aromatics; a de-alkylation reactor for selectively cracking C2+ alkyl chains from the C9+ aromatics, thereby forming the C6-C8 aromatics; and an aromatic extraction unit for extracting at least a portion of the C6-C8 aromatics.

Abstract: Increased paraxylene production through the use of a split feed reforming process, wherein hydrotreated naphtha is split into light, middle and heavy fractions. Each fraction is reformed separately to generate streams containing aromatic compounds. These streams can further be processed and can undergo dealkylation, transalkylation, disproportionation, isomerization, and separation steps to maximize paraxylene production. In addition, some streams are recycled or recombined in order to maximize paraxylene production.

Abstract: Sales gas output from a glycol dehydration unit in a gas plant is flown into a sales gas pipeline. One or more operational parameters of the glycol dehydration unit are received. One or both of an amount of glycol carryover and an amount of water carryover in sales gas output from the glycol dehydration unit in the gas plant are determined based on the one or more operational parameters of the glycol dehydration unit. An amount of glycol and water co-condensation in the sales gas pipeline is determined based on one or more operational parameters of the sales gas pipeline and the one or both of the amount of glycol carryover and the amount of water carryover. An amount of black powder formation of the sales gas is determined based on the amount of glycol and water co-condensation.
