Abstract

Heat Exchanger 212-E9 is one part of the working fluid Debutanizer unit with seawater on inner tubes and H2S on the outside of the tubes. These tubes have failed in the form of leakage. Here the analysis of leakage and the remaining life of the tubes are based on data from the inspection and analysis of general corrosion of the tubes. Part inlet tube erosion-corrosion as well as there are some leaks in the tubes. From the results of inspections in the field, erosion-corrosion of the inlet tube caused by the flow of seawater on the inlet tube containing a solution/coarse material. While the leakage that occurs in tubes due to the H2S concentration is too high, which is equal to 2 mol % H2S. In fact, the recommended H2S concentration is 0.32 mol % H2S. The high level of concentration of H2S is not suitable with the level of material resistance tubes. In the analysis of remaining life obtained maximum corrosion rate in the tubes of 0.2372 mm/year. With the usage time now is 6 year obtained remaining life of 2.5 year again. Referring to the results of the analysis of leakage and remaining life on the tubes is recommended that a filtering of the seawater before entering into the tubes and provide tubes protector on the inlet tube so that tubes are protected from erosion-corrosion, and which is necessary to regulate the level of concentration of H2S Heat Exchanger flowing at the recommended standards.

Abstract

The national electrification ratio is only 72.95%. As many as 27.05% of the territory in Indonesia has not been reached by electricity with various obstacles, one of which is because of the remote location so that access is difficult. One of the efforts to overcome the electricity problem is to take advantage of the potential energy sources around people's residences. One potential that might be used is a water energy source with low head and discharge. Ideally, this is done by using a generator system that uses a propeller type turbine. The difficulty of making propeller turbines is especially in the manufacture of housings and turbine blades. In this research, an attempt is made to simplify the turbine housing and turbine blades so that they are easy to manufacture. The design is made for Head (H) : 5 m Water flow (Q) : 0.11 m3/s Viscosity (ρ) : 998 kg/m3 Gravity (g) : 9.81 m/s2 Assumed hydraulic efficiency (ηh) : 0 ,80 Power (P) : 4,37 kW, Angle of attack (180o-β∞) 16o, Glide angle 55o, Thickness of inner blade(λ) 2,16o, Thickness of outer blade(δ) 2o. Simplification of the turbine housing is carried out by making the turbine housing from pipe iron and the simplification of the turbine blade is carried out by making turbine blades by eliminating the aerodynamic cross section of the blades, so that the blades can be made of steel plates without casting as is treated in aerodynamic sections. To see the effect of aerodynamic and non-aerodynamic cross-sectional shapes on efficiency, an efficiency test will be carried out.

Abstract

The purpose of this study was to analyze the effectiveness of the hardening-temper process on the strength of M8 bolts. The research was carried out through a hardening process with heating temperatures of 900°C, 1000°C, 1100°C, using a holding time of 15 minutes then quenched in aquadest cooling medium, then continued with a tempering process at the same tempering temperature of 400°C followed by cooling at room temperature. The torsional strength of the M8 bolt was obtained through torsional testing using the SM 1 MK II Torque Testing Machine. The results showed that the torsional strength of treated M8 bolts was lower than without treatment. Efforts to increase the torsional strength of M8 bolts with the hardening – tempering method are not recommended, because M8 bolts are made of low carbon steel which has low hardenability, so that the increase in torsional strength of M8 bolts is not significant.
