    Abstract: A horizontal sulfur condenser may include an exterior casing with a plurality of condenser tubes arranged longitudinally within the casing, a liquid sulfur reservoir at a longitudinal end within the exterior casing, and an internal baffle that protrudes into the liquid sulfur reservoir from the surface. The lowest of the plurality of condenser tubes is parallel to a wall of the exterior casing. A Claus process gas inlet is proximate a first end of the plurality of condenser tubes, which are arranged horizontally but are positioned vertically above the sulfur reservoir. A liquid sulfur outlet is located at the liquid sulfur surface. The baffle creates multiple chambers above the sulfur reservoir, such as a first chamber defined by the exterior casing and the baffle to receive condensed Claus sulfur in the liquid reservoir, and a second chamber defined by the exterior casing and the baffle to receive degassed liquid sulfur.

    Abstract: Methods and systems relate to upgrading light olefins, such as ethylene, propylene and butylenes, diluted in a gas mixture, such as refinery fuel gas. The upgrading yields products in a gasoline, distillate, lube oil or wax range without requiring purification or compression of the gas mixture prior to feeding the gas mixture to a reactor. In operation, the mixture contacts a solid oligimerization catalyst, such as silica supported chromium, within the reactor. This contact occurs at a first temperature suitable to produce oligomers that are formed of the olefins and adsorb on the catalyst in liquid or solid phases. Next, heating the catalyst to a second temperature higher the first temperature desorbs the oligomers that are recovered and separated into the products.
