    On 1/7, the Alky started to only process FCCU BB and no longer process Coker BB. Alkylation chemistry, neither likes contaminants nor diluents. Contaminants are direct acid consumers. The more contaminants in the feed, the more often the unit will be at an acid constraint. Diluents do not react in alkylation chemistry, but they take up space and decrease the effective area for isobutane and olefin to contact. With less contact, side reactions like polymerization are more likely to occur; polymerization

    interventions. RCT’s have predefined study samples built out of the target population and randomly assigned to different groups (placebo vs. new treatment). The observed effects of investigational treatments at defined time points constitute predefined endpoints. Pharmaceutical companies must meet this standard when working out levels of efficacy and safety that can be achieved by an experimental drug. It is important in a clinical trial to have randomization to prevent the results from being skewed. If

    concentration and is produced at a pH of 7. The indicator used in this experiment was Phenolphthalein which determined the end point, which was shown as a form of colour change. In this experiment, citric acid was titrated with sodium hydroxide producing an endpoint between pH range of 8.3-10. (EASYCHEM, 2018) Citric acid has three acidic protons therefore it is a triprotic acid (lumen, 2018). The accurate concentration of the sodium hydroxide must be known to determine the citric acid concentration. The aim

The sample size of looking at only 10 years is too small to have a statistical significance, while choosing using observational selection of endpoints in his data that support his claim. Third, Fred Singer also claims that climate change is a natural phenomenon, because it’s constantly changing all the time. This is an example of telling apart pseudoscience from science because, there is no clear
