Figures 2(a) and 2(b) show the results for a batch distillation column operating at constant reflux ratio of 2.0 with ten theoretical stages. In Figure 2(a) it is observed that at the bottom of the column, the composition of benzene decreased with time while the composition of the heavy components increased.arolo and Guarice [ 8 ] extended their continuous short-cut method to batch distillation columns and used an infinite stage column. Seader and Henley [ 9, 10 ] applied Sundaram and Evans [ 3 ] method and showed how the FUG equations were used to solve a simulation problem with constant reflux.
Executive Summary on Persistence and Retention Topics. â¢ Retention rates commonly measure the percentage of freshmen that re-enroll the next academic year as sophomores. The primary reason that retention rates, along with graduation rates, are important is that retention rates are. perceived as indicators of academic quality and student success. â¢ In addition to retention, persistence, a studentâs continuation behavior leading to a desired goal, helps describe.
Insurance retention (IR) is the portion of an insurance claim not covered by the insurance company. It is that portion of any loss paid by the insured. A deductible is the most common example of insured retention although there are other types of retentions. An insurance deductible on a liability policy is the amount that must be paid or reimbursed by the insured for each claim paid by the insurance company. In the case of third party claims, insurance companies must pay any legitimate covered claim and seek reimbursement of the deductible from their insured.
