UOP LLC, formerly known as Universal Oil Products, is a multi-national company developing and delivering technology to the petroleum refining, gas processing, petrochemical production, and major manufacturing industries. The company's roots date back to 1914, when the revolutionary Dubbs thermal cracking process created the technological foundation for today's modern refining industry. In the ensuing decades, UOP engineers generated thousands of patents, leading to important advances in process technology, profitability consultation, and equipment design. Wikipedia.

Catalytic dehydrogenation plays an important role in production of light (C3-C4 carbon range), detergent range (C 10-C13 carbon range) olefins and for ethylbenzene dehydrogenation to styrene. During the World War II, catalytic dehydrogenation of butane over a chromia-alumina catalyst was practiced for the production of butenes that were dimerized to octenes and hydrogenated to octanes to yield high-octane aviation fuels. The earlier catalyst development employed chromia-alumina catalyst and more recent catalytic developments use platinum or modified platinum catalysts. Dehydrogenation is a highly endothermic process and as such is an equilibrium limited reaction. Thus important aspects in dehydrogenation entail approaching equilibrium or near-equilibrium conversion while minimizing side reactions and coke formation. © 2012 Springer Science+Business Media New York.

Catalytic dehydrogenation is a critical and growing technology for the production of olefins, especially for propylene production. This paper will give an overview of advances in the catalysis science and technology for production of olefins by catalytic dehydrogenation, including the concomitant removal of H2 by selective oxidation. For light paraffin dehydrogenation, UOP has licensed the Oleflex™ process widely for production of polymer-grade propylene as well as isobutylene with over 12 million metric tons of capacity announced. Today there are nine UOP C3 Oleflex™ units in operation accounting for 55 % of the installed world-wide propylene production capacity from propane dehydrogenation technology. The heart of the process is a noble metal multi-metallic catalyst and the continuous catalyst regeneration (CCR) process. The coupling of catalytic dehydrogenation with selective oxidation of hydrogen allows one to design a process, which greatly improves equilibrium conversions while maintaining very high selectivity to olefin. The Lummus/UOP SMART™ SM process (Styrene Monomer Advanced Reheat Technology) allows 30-70 % capacity expansion, achieves a higher per-pass ethylbenzene conversion, and provides the most cost-effective revamp for higher capacity. Styrene Monomer Advanced Reheat Technology (SMART™) uses an oxidation catalyst and novel reactor internals to allow oxidative reheating between dehydrogenation stages. In the case of selective oxidation catalysts containing dispersed metal active sites, the role of diffusion and pore architecture is as important as the active metal sites. © 2012 Springer Science+Business Media New York.

One exemplary embodiment can be a process for cooling a vent stream from a receiver. Generally, the process may include providing a refrigerant including at least one compound contained in the receiver so the refrigerant leaking into the receiver can be compatible with the process.

Apparatuses and processes are provided for stripping gaseous hydrocarbons from particulate material. One process comprises the step of contacting particles containing hydrocarbons with a stripping vapor in countercurrent flow to remove at least a portion of the hydrocarbons with the stripping vapor to form stripped particles. Contacting the particles includes advancing the particles down a sloping element of a structured packing toward a reinforcing rod that is disposed along a lower channel portion of the sloping element. The particles are advanced over the reinforcing rod. The particles are contacted with the stripping vapor that is rising up adjacent to the lower channel portion.

Methods for forming bio-derived fuel products, upgrading bio-derived feedstocks, and processing bio-derived normal nonane are provided. In an embodiment, a method for forming a bio-derived fuel product includes providing a bio-derived hydrocarbon stream comprising at least about 50 wt % normal nonane and having a research octane number of less than about 10. The method further includes isomerizing the bio-derived hydrocarbon stream over a non-zeolitic, non-sulfated and/or non-halogenated catalyst to form the bio-derived fuel product with a research octane number of greater than about 50.
