Abstract: A liquid leak detector for above-ground tanks includes an upright standpipe connected to the tank so that the standpipe can be filled with liquid from the tank to the same level as the liquid in the tank. A pressure transducer is connected between the bottom of the tank and the bottom of the standpipe to measure the difference in pressure of the liiquids in the tank and standpipe. Any change in the liquid pressure at the bottom of the tank as a result of leakage from the tank will change the pressure differential on the pressure transducer. This changes the output of the transducer which can be recorded to indicate leakage from the tank.

Abstract: A novel composition is disclosed that is particularly useful as a lubricant viscosity index improver. The composition comprises branched C30-C10000 hydrocarbons that have a branch ratio of l ess than 0.19 and viscosity at 100°C between 725 mm2/s and 15,000 mm2/s. The novel compositions comprise the product of the oligomerization of C¿6? to C20 alpha-olefin feedstock, or mixtures thereof, under oligomerization conditions at a temperature between -20°C and +90°C in contact with a reduced valence state Group VIB metal catalyst on porous support. The compositions have viscosities at 100°C between 725 mm?2¿/s and 15,000 mm2/s. Using the foregoing compositions in admixture with mineral oil and synthetic lubricants provides novel lubricant blends that show an elevated viscosity index. The mixtures also show an increased stability to shear stress at high temperature with all blends notable by exhibiting Newtonian flow.

Abstract: Methanol or other alcohol is converted to high octane gasoline components by an integrated process wherein crude aqueous alcohol feedstock is extracted with a liquid extractant stream containing C4+ iso-olefin and reacted to form tertiary-alkyl ethers, such as MTBE. The aqueous raffinate is converted to olefinic hydrocarbons in a MTO catalytic reactor. Propene from the MTO reaction is reacted with water to produce di-isopropyl ether, which may be blended with MTBE and C6+ MTO hydrocarbons to produce high octane gasoline. Isobutylene and isoamylenes from the MTO reaction can be recovered and recycled as a liquid extractant stream.

Abstract: An integrated process for the production of alkylate and etherate rich high octane gasoline streams (113, 121 and 122) is provided which process comprises etherification (reactor A) to produce MTBE and TAME (113) in the presence of a high stoichiometric excess of methanol (110) followed by the conversion of unreacted methanol (114) in contact with zeolite type catalysts in the presence of aromatics (119) produce alkylated aromatics in gasoline. The light paraffinic effluent (120) from the methanol conversion zone (reactor B) is reacted in contact with a zeolite catalyst under aromatization conditions (reactor C) to produce an aromatics feedstream (124) for the methanol conversion reaction (reactor B). A supplemental olefinic feedstream (128) is provided to the methanol conversion zone (reactor B) after optionally serving as stripping medium for the separation (reactor E) of methanol (114) and etherate-rich C5 + gasoline (113) from the etherification reaction (reactor A).

Abstract: Surface layers of the earth contaminated with precipitates of alkaline earth metal sulfates including radium sulfate derived from subterranean waters brought to the surface of the earth, are decontaminated using an aqueous chemical composition including a polyaminopolycarboxylic acid such as ETDA or DTPA in combination with a synergist, preferably oxalate or monocarboxylic acid anion such as salicylate. The surface layers may be decontaminated in situ by applying the solvent to the earth to bring the precipitates into dissolved form after which the dissolved precipitates are leached into lower layers of the earth by percolation with water. Alternatively, the earth may be removed from its original site and decontaminated in a tank or lined pond after which the decontaminated earth may be returned to its approximate original site. There is also disclosed a method of decontaminating natural gas processing equipment using the aqueous chemical composition.
