[email protected] ABSTRACT Methanol is the simplest form of alcohol. Methanol is often referred to as methyl alcohol, wood alcohol or spirit which includes chemical compounds with the chemical formula CH3OH. Most of methanol, is produced from fossil fuels and more than 85% of global methanol production is based on natural gas reforming and gasification of coal. Biomass is biolog…
ABSTRACT Along with the times, the need for chemicals in Indonesia is getting bigger. One of the most widely used chemicals is ethylene oxide. This chemical, also known as epoxyethane is widely used in the chemical and pharmaceutical industries. The main raw material for the manufacture of ethylene oxide with the DOW Meteor process uses ethylene and oxygen. Ethylene oxide (oxirane) is the …
ABSTRACT The acetic acid industry in Indonesia is one of the chemical industries that has good prospects. This acetic acid product has a fairly wide market such as the Purified Terephthalic Acid (PTA) industry, the ethyl acetate industry, the textile industry, the rubber yarn industry and is also used as a semi-finished material to make chemicals, such as vinyl acetate, cellulose acetate, acid…
ABSTRACT High density polyethylene or high density polyethylene is one type of high-density polymer that is flexible, impact resistant, low temperature resistant, even freeze water resistant which is potential as a matrix candidate in making bone replacement composites. One process that can be used in synthesizing high density polyethylene is the CX-Mitsui process. CX-Mitsui processes there is…
ABSTRACT Polybutylene Terephthalate (PBT) is a type of synthetic plastic that is nonbidegradable or cannot be degraded by microorganisms. Polybutylene Terephthalate (PBT) is urgently needed as a raw material for the manufacture of electronics, military, shipping, medical devices to household appliances. The need for PBT increases along with the increase in the capacity of plastic food and …
Vinil Acetate is the simplest ether compound in the form of a colorless gas. Vinil Acetate has similar properties to Liquefied Petroleum Gas (LPG) so it can be used as a new energy source. The main raw materials for the manufacture of Vinil Acetate are Ethylene, Acetic Acid and Oxygen. The process used in the dimevinil acetate plant is an acetic acid gas process because it produces high yield a…
ABSTRACT A mixture of used cooking oil and pertalite has not been widely used by people as fuel for stoves. In general, kerosene is used as fuel in the stove, but the price of kerosene is very expensive. This study aims to find alternative fuels to replace kerosene for stoves. In order to grt the best performance of the stove, the treatment of variations in the ratio of used cooking oil-pertal…
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. Limestone size and burning time are two factors that affect the quality of the raw materials used to…
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 Pectin was a complex polysaccharide derivative compound that was abundant in vegetables and fruits, including oranges, apples, bananas, carrots, nuts, and garlic. Pectin had the ability to form a gel, making it crucial in the production of various food products such as jam, jelly, fruit preparations for yogurt, fruit juice, and other products. The objective of this study was to determ…
