Abstract

The Chemical Engineering Department offers two majors for undergraduate students, P technology. Both offer the option of performing a thesis experiment or undergoing an on-the-job training as part of the curriculum to satisfy the requirement for graduation. A student majoring in Sugar Technology (SUTC) has to submit the requirements specified by the sugar company offering the position of on -the-job-trainee. The training program takes place in the summer (April to May) which usually lasts for six weeks during which the student (s) familiarizes himself with the job taking tours of the plant and performing tasks given befitting Chemical Engineers majoring in Sugar Technology. For A.Y. 2008-2009, there were three sugar producing companies available to choose from the SUTC students to undergo their practicum: Busco Sugar Milling Co., Inc.(BUSCO) in Quezon, Bukidnon, Lopez Sugar Corporation in Sagay City, Negros Occidental, and Central Azucarera Don Pedro, Inc. (CADP, Inc.) in Nasugbu, Batangas. Seventeen SUTC students chose Central Azucarera Don Pedro, Inc. for their on-the-job training. The sugar central provided the schedule of activities for the students to undertake within the required 280 hours to cover the sections of the plant: Mills, Boiling House, Refinery, Boilers, Raw Sugar and Refinery Laboratories (Quality Control), and Wastewater Treatment. The students report to the Superintendents and shift supervisors of the specific sections Aside from the performing tasks given by the Superintendent or Shift Supervisor, the student gather data for their individually assigned special topics. The author's special topic was to compare the clarification efficiencies of the four-compartment (2006) and trayless(2009) clarifiers. The shift done in 2008, was to accommodate the increase in plant capacity brought by the expansion implemented. Clarification, in the Sugar Industry, primarily aims to remove the maximum amount of impurities in the cane juice to prepare the juice for the subsequent processes in raw sugar production. Without clarification, the production of high quality sugar with minimal loss is not possible thus the degree of clarification has great bearing on the yield of raw sugar. The principal factors involved in a clarification process are heat and lime ( Official Chemical Handbook for Philippine Sugarcane Industries, 1997). The different clarification processes employed in sugar production and operating parameters and equipments for the clarification process for the four-compartment and trayless clarifiers., crop year 2006-2009, were discussed and compared. Weekly factory statements from the raw sugar production quality control laboratory were used to compare the clarification efficiencies. The author found out that the use of the trayless clarifier not only addressed the increased capacity but also the persisting problems encountered with the four-compartment. The trayless clarifier more efficiently the mixed juice when capacity, mud withdrawal, control of process parameters, and liquidation and cleaning operations were considered.
