Abstract

Rolling oil is one kind of the lubricants which is used for metal working especially for cold rolling mill (CRM), roll collant, roll oil and pickle oil.Mostly, lubricat based rolling oil was derived from mineral or synthetic oil where its source has been depleted. Castor oil has some advantages to be employed for lubricants or rolling oil based materials since it has high load wear index lubricity, and viscosity as well as low pour point. This research was aimed at investigating the production of rolling oil using castor oil with oxidation treatment. Chitosan was also used to know its effect on rolling oil characteristics. The method of rolling oil production was designed y adding NaHSO4 as catalyst into castor oil, dehydrating of castor oil at 200 C during three hour, cooling of castor oil at room temperature, dissolving buthylated hydroxy toluene (BHT), dehydrating oil (oxidation) at 100 C during 8 hours, addition of 1 %, 3 % and 5 % of chitosan solution into oil, and dissolving O-fenilfenol into oil with oxidation treatment showed better result in term of acid number, iodine number, viscosity, and density. The best result of experiments was showed for the oxidixed rolling oil with dehydrated treatment with 5 % chitosan aolution which has acid value 1,1 mg KOH/gr oil, iodine number 59,3 gr iod/100 gr oil, saponification value 196,9 mg KOH/g oil, viscisity 180, 6 cps, density 0,97 gr/ml. In coclusion higher chitosan concentration resulted lower acid and saponification value. On the Other hand higher chitosan concentration affected higher iodine number and viscosity.

Abstract

Deodorizing and reaction time of degumming are some of the most important factors that can affect the quality refined vegetable oils or its derivatives. The results of unit operations in doedorizing and degumming give low viability of product especially produced by vegetable oils smallholder industry in Indonesia. To increase quality of those and income producer there is a need to enhance process by introducing appropriate equipments. This study was devoted in designing and testing centrifuge for degumming of crude vegetable oils (Palm kernel oil) and vacuum deodorizer using jet pump for refining oils. The maximum capacity of sentifuge constructed is 12 liters and it was equipped with four container and 1 horse power of induction motor. The performance test of centrifuge showed reaction time for degumming was two hours with maximum impurities or gums (7%). This reaction time is shorter than those of conventional degumming process using settling tank e.g all night reaction time. Deodorizer reactor has capacity of 40 liters oil processed, and it is generated with 1,1 hp of induction motor. steam from small boiler unit was introduced to the doedorized tank to reduces impurities and free fatty acid (FFA). The reactor was equipped with metal heater element of 5000 watt which immersed in silicon oil as heating medium and it was covered by insulator. The reaction temperature of deodorizing process was 160 degree celcius. Palm kernel oil quality processed by vacuum deodorizer tested e.g. free fatty acid (FFA) was 0,03%, peroxide number was 3,03 meq/kg, moisture content was 0,94%,anisidin number was 3,97, and color were yellow and red (0,4 and 7). It means that those results of refined palm kernel oil caracteristics meet the standard required.
