Chemical engineering distillation column Essay Example | Topics and Well Written Essays - 500 words
Chemical engineering distillation column - Essay Example The required task is therefore to determine if the column has potential to efficiently distillate within economic operation costs. While a five-step procedure is recommended for testing the facility, time is scarce and not all the steps can be implemented. The steps are; calculation of the theoretical capabilities of the distillation column in the lab, preparation of an accurate vapor liquid equilibrium diagram of water and ethanol, accounting for the energy usage of the distillation process, accounting for the final products ethanol concentration, and analysis of the costs and benefits of obtaining higher yields against higher purities. The time scarcity however dictates that only two of the steps are adopted in order to determine the columnââ¬â¢s capacity. My team would choose to prepare an accurate vapor liquid equilibrium diagram for water and ethanol, and to account for the final productââ¬â¢s ethanol concentration. The vapor liquid equilibrium would be preferred because of its theoretical basis that can be used in an experiment to test the facilityââ¬â¢s efficiency and freedom from errors. This is because for any mixture of two fluids and across varying temperatures or pressures, there is an equation that determines corresponding mole ratios of mixture components in the vapor state given a temperature or pressure. A given volume of water and ethanol can then be used in the column and measurements taken at a given temperature and mole ratio determined. If the experimental values correspond to theoretical values, as determined by Raoultââ¬â¢s theory, then the column is approved to be operationally efficient. It is therefore an accurate measure of efficiency (Theodore, Ricci and Vanvliet, p. 233). Accounting for the final et hanol concentration is another efficient process for determining the operational efficiency of the distillation column. This is because of the

The Legal Framework for Criminal Investigations and the Relationship Essay
The Legal Framework for Criminal Investigations and the Relationship with the Criminal Justice System - Essay Example This speaks itself about the importance of tough criminal investigation procedures. In order to collect reliable and secure evidence, the investigators must put in concrete efforts so that the person found guilty should be punished in accordance with law. Therefore, for a criminal prosecution to become successful, it is extremely important that the Crown Prosecution Services should provide solid and reliable evidence to the court of law to punish the culprits. ââ¬Å"In a number of countries where democratic set up exists and where rule of law succeed, the burden of proof lies on the shoulder of the prosecutionâ⬠(Conner et al 2008). The safeguards within the legal framework designed to protect people under criminal investigation Under the UK Law, those who are convicted by the lesser courts may file an appeal to higher court for the answer they are looking for. ââ¬Å"The hierarchy of the courts starts from the magistrates / youth courts to the Crown Court, from the Crown Court to the Court of Appeal. However, in some exceptional cases further appeal is allowed to the Supreme Court onlyâ⬠(Cate 2008). Appeals to Courts that are higher up in jurisdiction are restricted to the point of law. If the right of appeal is obsessive for a convicted defendant, then he or she has the option to pursue to the administrative body known as Criminal Cases Review Commission (CCRC). If there is malpractice found then this renders the conviction irrelevant and sums up to the miscarriage of justice. ââ¬Å"There are two sorts of ââ¬Ëwrongful convictions a) One where the defendant is convicted unfairly b) other where a lack of fair trial makes it difficult to determine whether the defendant is guilty or notâ⬠(Sanders and Young 2010). Conviction through unfair means is considered a miscarriage of justice that raises many suspicions. The CPS sometimes allows appeals against acquittal especially if there is an error found in the law. For example, a jury member can be rejected if they attempt to prosecute with certain kinds of evidence that the judge feels that the police lacked the required legal power to secure that evidence. In a few cases, when compelling evidences of guilt comes to surface, fresh cases against the earlier acquittals can be restarted. ââ¬Å"An element of criminal justice, which is not taken into account, is criminal defense; as per the law of the land, anyone arrested and taken into custody by the police officials is entitled to receive free legal aid from an adviser, usually a qualified legal practitionerâ⬠(Sanders and Young 2010). Great Britain is known to set aside funds for free legal representation to its people in the ordinary courts and the Crown Court. The wealthy classes of people usually do not take the benefit of legal representation and normally pay their legal fees from their own resources. ââ¬Å"The numbers of litigants have two options a) present themselves or b) engage a solicitor to plead the cases of the poor. This is done by the government which hires the services of solicitors for them at the governmentââ¬â¢s expensesâ⬠(Sanders and Young 2010). The operation of safeguards within the legal frameworkà Section 47 enquiries aim at to minimize the destruction on the personality of a child and to ensure that the families are treated in a respectable way by the agencies. The Children Social Care organizations should appraise the guardians responsible for the security of
