A process is described for separating the heavier hydrocarbons from a gaseous hydrocarbon feed wherein a first separator is employed to separate partially condensed gaseous feed and wherein the vapour portion undergoes work expansion and is fed to a fractionation column. The liquid portion is subcooled in heat exchange with the overhead vapour from the fractionation column, expanded, evaporated to provide refrigeration at a low temperature level, and fed to the fractionation column. The rewarmed residual vapour is subsequently compressed to a pressure suitable for export, with a portion of the compressed gas being cooled, condensed and recycled back to reflux the top section of the fractionation column.Also described is a process wherein a first separator is employed to separate partially condensed gaseous feed and wherein the vapour portion undergoes work expansion and is fed to a high pressure wash column.

PCT No. PCT / JP97 / 00572 Sec. 371 Date Jan. 8, 1998 Sec. 102(e) Date Jan. 8, 1998 PCT Filed Feb. 27, 1997 PCT Pub. No. WO97 / 31990 PCT Pub. Date Sep. 4, 1997This invention provides a method for reclaiming oil from waste plastic in such a way that thermosetting resins and solid foreign matter in the plastic will not pose a problem. This method greatly reduces the burden of presorting the garbage or industrial waste. To achieve this objective when oil is to be reclaimed from a waste plastic containing chlorine compounds, such as vinyl chloride, the plastic must first be stripped of chlorine. Prior to pyrolysis, while being conveyed forward in a continuous stream, the plastic is mixed with heated sand and / or an additive agent to raise its temperature to 250-350 DEG C. This creates a product which is comprised of a mixture of sand and substantially dechlorinated plastic. The product is mixed with heated sand to heat it directly to a temperature of 350-500 DEG C. It is maintained at this temperature until pyrolysis occurs. In order to obtain high-quality oil with a low boiling point, a first gas / liquid separation process separates the product obtained from the aforesaid pyrolysis into liquid high-boiling point oil, gaseous low-boiling point oil and low molecular-weight gases, and recirculates the liquid high-boiling point oil to the pyrolysis process, and a second gas / liquid separation process separates the gaseous low-boiling point oil and low molecular-weight gases into liquid low-boiling point oil and low molecular-weight gases. The first and second gas / liquid separation process are connected in sequence.

Methods for removing heavy metals from water using chemical precipitation and field separation methods
InactiveUS6896815B2Small sizeChemical cost reductionSolid sorbent liquid separationGold compoundsWater useSludge
A two-step chemical precipitation process involving hydroxide precipitation and sulfide precipitation combined with “field separation” technology such as magnetic separation, dissolved air flotation, vortex separation or expanded plastics flotation, effectively removes chelated and non-chelated heavy metal precipitates and other fine particles from water. In the first-step, the non-chelated heavy metals are precipitated as hydroxides and removed from the water by a conventional liquid / solids separator such as an inclined plate clarifier to remove a large percentage of the dissolved heavy metals. The cleaned water is then treated in a second precipitation step to remove the residual heavy metals to meet discharge limits. In the second precipitation step, any metal precipitant more effective than hydroxide for metal precipitation can be used. The invention improves metal removal, lowers cost because fewer chemicals are used, produces less sludge, and reduces the discharge of toxic metals and metal precipitants to the environment.
