202327 · Abstract— A pseudo-homogeneous model was developed for fixed bed catalytic styrene monomer reactor based on the reaction mechanisms and mass and energy balance equations. With the proposed mathematical model, the profiles of ethyl benzene conversion, styrene yield and selectivity were achieved through the length of catalytic bed …

6 · A hydrogen explosion and fire occurred in the benzene unit of a styrene plant in a large petrochemical complex. The unit was being restarted following a scheduled maintenance shutdown. The explosion followed the release of about 30 kilograms of 700-psig hydrogen gas from a burst flange into a compressor shed. Two men were killed and …

Preferred isolation and control valves for chemical plant and petrochemical plant separators. Separators can be both pre and post the furnace / reactor to separate phases or pre-filter the raw materials or feedstock, as well as part of the extraction process. Usually, there are multiple separator systems to handle the different phases of purification of the end …

2019215 · Abstract In this work, a thermally stable and eco-friendly separator composed of polyvinyl alcohol modified cellulose/styrene-co-acrylate composite (pCSA) was prepared via a facile and cost-effective phase inversion process. The results indicated that styrene-co-acrylate (SA) endowed the membrane with more network junctions, thereby, …

1998101 · In this article, styrene was copolymerized with BA (sparingly soluble in water) and MA (rather soluble in water) in both emulsion and microemulsion. The reactivity ratios were determined by n.m.r. according to Gan et al. [10] The differences between reactive ratios were discussed, and the copolymerization loci in microemulsion …
