Abstract

Dye waste that contains synthetic dyes like Direct Black 38, Remazol Yellow FG, and Reactive Red 2 in high concentration, is the main source of water pollution which can decrease the quality and ecosystem of water due to its difficult degradation properties. Physical and chemical adsorption method using adsorbent like activated carbon-chitosan composites can be carried out to decrease the concentration of dye waste. The purpose of this research is to find out the adsorption capacity of activated carbon-chitosan composites on Remazol Yellow FG dye waste using fixed bed column continuous system. The composites were made by adding 1:1 of the activated carbon into chitosan solution and then dropping it into the 15% NaOH-96% Ethanol in 4:1 v/v as the coagulant. Then, composites were used to adsorb the dye waste in order to find out the adsorption capacity. Next, samples were analyzed using UV-Vis Spectrophotometer. The results showed the optimum point was on 8 mL/min flow rate. The best adsorpstion capacity of 1.21781 mg/g was obtained in Thomas and Yoon-Nelson’s Models.

Abstract

Start up is the first step in the operation of the factory. The start-up process at the Ammonia Plant Operations department 1A requires some preparation, namely draining the entire system with nitrogen and the required system line-up. Nitrogen circulation is used for heating up several units, such as reformers and bycatch. Heating up is done so that the temperature of the reformer and bycatch units can be quickly achieved and the process can take place immediately. The description of the heating up process when improvised nitrogen circulation is carried out using a natural gas booster compressor, this process simultaneously goes through the desulfurized unit for heating up. So there is no need to use natural gas for heating up the desulfurization unit and then throwing it away. The responses carried out are data analysis, data collection and data processing. Based on the results of the economic analysis, it can be seen that at start-up by carrying out improvement conditions it will be more efficient because natural gas that is usually wasted is no longer wasted and gains additional profits from the gas, production will be 3 hours faster so that profits increase, and save the amount of process gas and fuel used for the start-up process for 3 hours. And the time needed to return the capital issued is four times the start up.
