Combustion in industrial burners is a critical operation in the chemical process industries (CPI) for supplying thermal energy for heat transfer, fluid heating, steam generation, distillation, endothermic chemical reactions, metal melting and others. Burners are mechanical devices utilized for mixing…
Follow these recommendations to select the right centrifuge for your application Many chemical process operations require the separation of multiple phases. This can be done in a number of ways, including simple gravity separation, traditional or crossflow membrane filtration and…
Ongoing advances in both adsorbent materials and system engineering allow today’s pressure swing adsorption (PSA) systems to produce nitrogen of varying purities and volumes at relatively low cost compared to cryogenic air separation Nitrogen production that is carried out using…
This column is based on “LLDPE Production via Gas-Phase Process — Cost Analysis,” a report from Intratec. It can be found at: www.intratec.us/analysis/lldpe-production-cost. Linear low-density polyethylene (LLDPE) is a copolymer of ethylene and longer-chain alpha-olefins, manufactured on commercial scale via…
A handful of compounds derived from natural gas and crude petroleum are converted into a vast array of industrial petrochemicals. Starting materials for most petrochemical intermediates include synthesis gas, ethylene, propylene, butadiene and BTX (benzene, toluene, xylenes). This one-page reference…
