Petrochemicals

Present vacuum resid conversion processes, either coking or hydroconversion, are far from achieving their maximum conversion. With the remaining petroleum resources, on average, having a greater fraction of the vacuum resid fraction, it is imperative that new resid conversion processes or schemes...

(Please Note: the audio does not start until 5 minutes 20 seconds as the speaker's microphone was not turned on.) A number of models have been proposed for the prediction of fouling rates in heat exchangers forming the pre-heat trains used in crude oil distillation units. Most of these models...

Crude oil distillation accounts for a large fraction of the energy used in oil refining. Crude oil contains a variety of substances which tend to deposit as fouling layers in heat exchangers, and this results in decreased energy recovery and requires increased energy input to the furnace. CDU pre-...

Availability of pure olefin monomers is a key step in the production of polymers. These olefins are mainly produced by steam crackers. KataLeuna offers a wide range of catalysts and adsorbents to purify the various steam cracker cuts. This contribution will report on the latest catalyst...

Considering the rapidly increasing demand for light olefins in the emerging markets, especially propylene, as petrochemical feedstocks, apart from steam cracking a number of processes such as catalytic cracking and metathesis are being modified and/or developed to enhance the propylene production...

Reliable operation of an Olefin gas/liquid dehydrator requires careful attention to the integrity of the grid supporting the molecular sieve. Problems with retention of the sieve can stem from many points in the design, fabrication, and installation process for these assemblies. Two case studies...

This session will develop a fundamental understanding of how cycle time variation in stages of a supply chain propagates into measures of overall cycle time. Application can be seen in supply chains and inside plants with batch processes. While the sources of variation are symmetrical and can be...

Since radiant coils operate under severe conditions of carburization, oxidation and erosion tube material selection plays an important role. Schmidt + Clemens and the R&D-institute HDZ have developed a new bench-scale unit to simulate high temperature corrosion of alloys in petrochemical plants...

Increased emphasis is being placed on renewable, sustainable, domestic forms of energy, including transportation fuels, at national, state and local levels. Successful deployment of alternative solutions to petroleum-based liquid fuels for the transportation industry is dependent upon technical,...

This tutorial will begin with a brief introduction to molecular sieves followed by a description of the process, covering overall operation of the charge gas dryer including adsorption and regeneration steps. Key design considerations will be discussed along with optimization and troubleshooting...
