Various substantially styrene-, methylstyrene- and ethylbenzene-free C6-C9 aromatic hydrocarbon blends are produced from a hydrocarbon feed stream containing C5-C9 aromatic hydrocarbons including styrene, methylstyrene and sulphur compounds by first separating the stream into a distillate containing C5- C7 hydrocarbons, and a bottoms fraction containing C8 and C9 hydrocarbons; and converting the styrene and methylstyrene to their corresponding ethers by reacting with a C1-C3 lower alcohol in the presence of a selective acidic etherification catalyst. The effluent may be sent to a gasoline pool for blending or the effluent is separated by distillation into an ether stream and either a C8 or a C8-C9 aromatic hydrocarbon rich stream. The C5-C7 distillate is hydrogenated.

A two-stage sealed magnetic filter continuously removes magnetic and non-magnetic contaminants from liquid process streams. Elongated non-magnetic holder sleeves (13) encasing magnet bars attract magnetic contamtnants while a screen cylinder (14) captures non-magnetic contaminants. The magnet bars are accessible without having to open the interior (30) of the housing (1) to the environment. Thus, during maintenance, removing the magnet bars from the holder sleeves releases the magnetic contaminants that have adhered to the holder sleeves into the screen cylinder which partially encloses the holder sleeves. Contaminants are flushed out of the magnetic filter without exposing workers to potentially hazardous substances. Polymeric sludge occluded with iron compounds can be effectively removed from streams in refineries and chemical plants. The iron compounds are formed from carbon steel which is prevalent in plant machinery and that corrodes in the presence of acidic contaminants.

Recovering high purity benzene from hydrocarbon feedstock containing aromatics and non-aromatics is implemented by simple and low-cost modifications to conventional extractive distillation columns (EDCs). Methyl cyclohexane (MCH) that is generated through non-selective hydrogenation of toluene in hydrodesulfurization (HDS) units is a major contaminant in benzene production. To meet MCH specifications, often times the extractive distillation (ED) process for recovering purified benzene is operated with excessive benzene loss to the overhead raffinate stream, producing a lower quality non-aromatic product. Novel techniques (1) remove operational constrictions of the HDS unit on MCH production, thus lengthening the catalyst life and (2) allow the EDC to drive essentially any amount of MCH away from the bottom benzene product without concerns with benzene loss to the overhead raffinate stream and (3) recover benzene from the overhead raffinate stream to upgrade the quality of non-aromatic product and increase the benzene product recovery.

An energy efficient, high throughput process for aromatics recovery can be readily implemented by revamping existing sulfolane solvent extraction facilities, or constructing new ones, so as to incorporate unique process operations involving liquid- liquid extraction and extractive distillation. Current industrial sulfolane solvent based liquid-liquid extraction processes employ a liquid-liquid extraction column, an extractive stripping column, a solvent recovery column, a raffinate wash column, and a solvent regenerator. The improved process for aromatic hydrocarbon recovery from a mixture of aromatic and non-aromatic hydrocarbons requires transformation of the extractive stripping column into a modified extractive distillation column. The revamping incorporates the unique advantages of liquid-liquid extraction and extractive distillation into one process to significantly reduce energy consumption and increase process throughput. The revamp entails essentially only piping changes and minor equipment adjustments of the original liquid-liquid extraction facility, and is therefore, reversible.

In a method of blocking a water-out zone in a gas well by dumping cement and injecting pressurizing gas, a gas is injected into a target well to push and press accumulated water in the well back into the formation surrounding the well, so that the well is water-free; meanwhile, a dump bailer is lowered to the water-out zone in the well using a wire line. When the dump bailer has reached the water-out zone, it is controlled to open a bottom opening thereof to release cement milk loaded therein. The released cement milk accumulates in the water-out zone and then slowly flows into a gravel layer between a screen pipe and a wall of the well.

An energy-efficient extractive distillation process for producing anhydrous ethanol from aqueous/ethanol feeds containing any range of ethanol employs an extractive distillation column (EDC) that operates under no or greatly reduced liquid reflux conditions. The EDC can be incorporated into an integrated process for producing anhydrous ethanol used for gasoline blending from fermentation broth. By using a high-boiling extractive distillation solvent, no solvent is entrained by the vapor phase to the EDC overhead stream, even under no liquid reflux conditions. The energy requirement and severity of the EDC can be further improved by limiting ethanol recovery in the EDC. In this partial ethanol recovery design, ethanol which remains in the aqueous stream from the EDC is recovered in a post-distillation column or the aqueous stream is recycled to a front-end pre-distillation column where the ethanol is readily recovered since the VLE curve for ethanol/water is extremely favorable for distillation.

An energy-efficient extractive distillation process for producing anhydrous ethanol from aqueous/ethanol feeds containing any range of ethanol employs an extractive distillation column (EDC) that operates under no or greatly reduced liquid reflux conditions. The EDC can be incorporated into an integrated process for producing anhydrous ethanol used for gasoline blending from fermentation broth.

The invention disclosed relates to catalytic distillation column internals providing improved liquid reaction mixture and catalyst contacting for simultaneous catalytic reaction and separation of the reaction mixture. The invention is an improved catalytic distillation apparatus providing optimum balance of catalytic reaction and mass transfer steps, wherein distribution, mixing and feeding of liquid reaction mixture to the reaction zone and distillation section are better controlled and more uniformly applied. At least one catalyst bed is situated in at least one receiving pan of a distillation tray so that the tray performs the functions of both of the reaction section and the distillation section of the catalytic distillation column simultaneously within a stage.

A highly effective liquid-liquid extraction process to remove nitrogen compounds and especially basic nitrogen compounds from aromatic light petroleum oils with excellent recovery employs de-ionized water, which can be acidified, as the extractive solvent. The product is an aromatic hydrocarbon with ultra-low amounts of nitrogen poisons that can deactivate acidic catalysts. The extracted oils are suitable feedstock for the subsequent catalytic processes that are promoted with the high performance solid catalysts, which are extremely sensitive to nitrogen poison.
