Abstract

Base Sediment & Water (BS&W) is indicated high has to be as a corrosion factor in the pipeline. Corrosion is the damage or degradation of metals due to oxidation-reduction reactions between a metal and various substances in its environment which produce unnecessary compounds. Corrosion can be influenced by several factors, such as NaCl content, BS&W composition, dissolved gas content, pH, flow rate and temperature. The composition of BS&W can have an impact on the corrosion rate of the API 5L Gr B steel pipe.   Keywords : Pipeline, BS&W, Corrosion Rate

Abstract

Surfactants are chemical compounds that are surface active that can reduce surface tension. Methyl Ester Sulfonate (MES) is an anionic surfactant that can be produced from the reaction of methyl esters made from vegetable oils with sulfonating agents. Palm oil is vegetable oils that can be produced as MES surfactants. This study aims to make MES from methyl esters based on Crude Palm Oil (CPO) with various sulfonating agents (NaHSO3; Na2S2O5; H2SO4 ) and time variations (120; 150; 180; 210; 240 minutes). To speed up the reaction in the sulfonation process, the addition of a 2% Al2O3 catalyst was used. The process of making MES is through the sulfonation process, the next process is the process of purification, neutralization, and drying. The results obtained the best sulfonating agent, namely Na2S2O5 at 240 minutes with a surface tension value of 26.2421 dyne/cm, an acid number of 1.6830 mg KOH/g MES and emulsion stability up to 10 minutes.

Abstract

Palembang Jumputan Fabric, or commonly called Rainbow Fabric, one of the crafts produced with the jumputan technique, (Tie and Dye) is a technique of dyeing fabric by dipping it in colored ink, by adding silk and satin materials with a natural mixture of coloring method of natural and chemical origins. There have been many studies regarding the treatment of jumputan fabric wastewater using adsorbents, but this method has a weakness. Similarly, it allows the adsorbent to be left behind in the jumputan fabric wastewater. The purpose of this research is to treat the liquid waste of jumputan fabric with polysulfone membrane to reduce dry stuff . The membrane will be made using DMAc solvent and a PEG 400 additive with a composition of 18% polysulfone; 62% Dmac; and 20% PEG. The liquid waste of jumputan cloth will be purified with polysulfone membrane by ultrafiltration. In this study, the liquid waste of jumputan fabrics with variations of PAC Coagulants 500 ppm, 1000 ppm, and 1500 ppm was used, as well as with pressure variations of 0.5, ; 1; 1.5 , and 2 bars. From the results of the study, it was found that the rejection of the dye was 23.69%. Keywords: Liquid Waste, Polysulfone, Ultrafiltration
