Abstract

Temurui leaves or curry leaves (Murraya Koenigii) are widely available in Aceh, this plant is one of the wild plants, but unfortunately it is only used as a cooking spice by the community. In this study, the temurui leaves were distilled to extract the essential oil, thereby increasing the economic value of the temurui leaves. The tests carried out to determine the criteria for the essential oil of temurui leaves (curry leaves) were yield, density, refractive index and GC-MS analysis. The temurui leaf distillation is operated by the steam boiler distillation method and uses leaves that have been aerated, using variations in drying 0, 1, 2, and 3 days and distillation time variations of 4, 5, 6, and 7 hours, with a distillation time of 7 hours. hours and 1 day of drying to get the best yield and distillate with a value of 21.5 ml. Based on the research conducted, it can be concluded that the longer drying time can affect the yield obtained, and the longer the refining time, the more oil distillate is obtained. The results of GC-MS obtained Caryophyllene of 76.33% which has a function as an antibacterial, and -Humulene 18.49% which has a function as a prevention of cancer cell growth, with the highest density of 0.8928 and the result of a refractive index of 1.5128. it has fulfilled the SNI for teumuri leaf essential oil. Keywords: Murraya Koenigii, Temurui Leaves, Distillation, Curry Leaves.

Abstract

Absorption was a separation process between gas fluids using liquid fluid media. The glycol contactor aims to separate the water content contained in the gas using tri-ethylene glycol media with process conditions at a pressure of 795-810 psi and a temperature of 85-110 oF. The contact process between fluids is assisted by the Intalox Saddle type packing which aims to maximize the contact process between fluids and it is hoped that the absorption process that occurs can be maximized. Tri-ethylene glycol which has absorbed the water content in the gas is regenerated in the glycol burner. This analysis used 4 packing variables (Raschig Rings, Pall Rings Plastic, Berl Saddles Ceramic, and Intalox Saddles Ceramic), 5 flow rate variables (1600, 1800, 2000, 2200, and 2400 BPD) and this analysis use the Hysys simulation program. Based on these variables, the absorption efficiency analysis results are obtained in the range of 93-94%, and the flooding percentage is 21-36%. It can be concluded that the type of packing is very influential on the percentage of flooding. Pall Ring Plastic was the type of packing with the lowest flooding percentage. According to research, lower flow rates increase the efficiency of H2O absorption.

Abstract

The lube oil system in the compressor plays an important role for any rotating equipment because it functions to provide lubrication against the effects of friction on various rotating equipment. This overhead tank works by gravity to distribute lubricating oil from operating speed to zero rpm. The large volume of lube oil provides lubrication to the compressor bearings when the normal circulating flow from the pump stops and is assisted by the backup flow from the overhead tank. The purpose of this approach is to calculate the need for lubrication when an electrical fault occurs in the Boil-off Gas compressor (K-6801). Based on the results of analysis and calculations where the Boil-Off Gas Compressor (K-6801) is the object of observation, the amount of lubricating oil needed for the remaining rounds is 1885 liters while the amount of lubricating oil available in the field is 1528,286 liters. From the calculation results, 1528,286 liters is sufficient based on the reference API Standard 614 edition 4, chapter 2, Section 1.4.10.2 because it has exceeded the 20% reduction from 1885 liters, namely 1508 liters. The height of the overhead tank that is suitable for flowing lubricating oil to the compressor bearings is 5.2588 meters above the compressor with a distribution pipe diameter of 3 inches and an orifice bore diameter of 1 inches.
