ABSTRACT The stripper serves to process the resulting condensate and evaporation in the final effect on the evaporator with the aim of reducing the COD content in the condensate so that condensate with a lower COD value is obtained. In addition to reducing the COD content of condensate, by-products are also obtained from the stripper, namely SOG (Stripping Odorus Gas) which can then be repro…
ABSTRACT In the Chemical Plant department, caustic soda are produced by the electrolysis of a saturated solution of sodium chloride/brine (NaCl). The electrolysis process is a prosses by which electric current is passed through a substance to effect a chemical change. The chemical change is one in which the substance loses or gains an electron (oxidation or reduction). Electrical energy (power…
ABSTRACT This process requires a lime kiln unit to burn lime mud so that a calcination reaction occurs which produces lime. Product quality is determined by various factors, one of which is the dryness of the lime mud. Drynes in lime is the water content in lime mud. To get the dryness of lime there are several value factors that must be maintained such as WSS (water soluble sodium), Vat level…
ABSTRACT The growth of technology and the world today is very fast as time passes. One industry that has a big role for the economy in Indonesia is the pulp and paper industry. Paper is defined as a thin material produced from fibers derived from pulp. One of the processes in papermaking is calendering. Calendering is a refinement process carried out with the help of pressure and heat. One of …
ABSTRACT Along with the development of the paper industry in the world, it is very important to pay attention to the quality of the paper produced. One of the things that affect the quality of the paper produced is the paper filler or filler. Company PT. RAPP produces PCC as a paper filler.

ABSTRACT Division Water Treatment Plant at PT. Riau Andalan Pulp and Paper (RAPP) processes kampar river water into water that meets factory standards so that it can be used for mill operations. There are several stages of water treatment including; processes of aeration, coagulation, flocculation, sedimentation, filtration and disinfection. In the process of treating raw water into clean wate…
ABSTRACT The paper production process produces a lot of waste, such as white water which still contains high total suspended solids (TSS). To overcome this, PT. RAPP uses a disc save all system which functions to recover fiber and separate the filtrate into several types of filtrate, namely super clear filtrate, clear filtrate, and cloudy filtrate. In this final project, we learn about dis…
ABSTRACT The roughness of the paper surface is an important parameter in paper making. Roughness is defined as the condition of the uneven surface of the paper, the basis for measuring it is how much air ml/min can come out of the surface of the paper. In this study the authors analyzed the roughness values of copy paper and offset paper. Observations were made on copy paper MR060670 and offse…
ABSTRACT Recausticizing is part of the kraft chemical recovery process which aims to regenerate white liquor by reacting green liquor with lime (CaO) originating from the lime kiln process. The green liquor reacts with the lime in slaker, where the reaction that occurs is exothermic. This reaction causes an increased temperature in slaker. The temperature difference between the green liquor in…
ABSTRACT PT Riau Andalan Pulp and Paper as one of the largest Indonesia’s pulp and paper factory, produces screen reject pulp waste from the Fiberline Department, and sludge from the Effluent Treatment Department in large quantities. Both types of waste are reused as fuel in the Power boiler unit (Steam Power Plant unit) to reduce landfill’s heap. Power boiler #3 uses biomass dominance fue…
ABSTRACT Currently, Indonesia has installed 20 airborne radar points and 11 maritime radars. However, not all areas in Indonesia can be reached by this radar. With the limited number of existing radars and the large number of areas that must be monitored, a portable radar such as a man-pack radar is needed. Man-pack radar is a radar that can be used on a mobile basis and can be used in remote …
