Abstract

In this article the author conducts research related to energy consumption studies on electric motorbike vehicles (SEMOLI) made and developed by the author. The purpose of the energy consumption study is to determine the energy consumption of electric motorbike vehicles that have been made for further improvement and development. The method used is experimentation with the first phase testing on a straight flat road for one kilometer with flat road conditions, this phase of experimental results shows an average energy consumption of 30 Wh, for an average uphill road consumption of 40 km / h and for the second phase of experimental data using experimental methods with speed parameters 30 - 35 km energy consumption has an average of 30 Wh, at speeds of 40 - 45 km / h energy consumption has an average of 28 Wh, and 50-55 km / h average energy consumption of 27 Wh. The test results show that on flat road conditions and the increasing speed, the energy consumption will decrease.

Abstract

Natural gas production areas and processing sites for use in the residential and industrial sectors are separated by a long distance. Contaminants such as H2S and CO2 are present when natural gas is transported. The reaction process that occurs in the pipe walls will experience a reduction in material. A process that occurs repeatedly over a long time will form deposits at the bottom of the pipe. This research investigates the sludge produced by the pigging process every month. The sludge characters are identified using SEM and XRD testing, while the condensate is examined using XRF testing. The XRF results show that the presence of Cl- in the condensate increases the anodic reaction in the corrosion process. Condensate has a pH of 5-6, which will cause corrosion around internal piping. Sludge produces Fe3O4, FeS, and FeCO3. Fe3O4 is more dominant than FeS and FeCO3. More FeS is produced by % mol H2S than by % CO2. Because of the existing FeS, the particles formed are irregular.
