Liquefied Petroleum Gas (LPG) Bottling Process and Required Safety During Bottling: A Case Study

Abstract

Energy security is very important in the current world. Liquefied Petroleum Gas (LPG) is one of the significant energy sources. LPG can be produced from natural gas processing as well as crude oil refining. Now LPG is available in different sizes of cylinder. The bottling system of LPG in the cylinder is the main discussion topic of this paper. Safety requirement during bottling work is also explained in this research article. LPG cylinder can be filled in both automatically and manually. The automatic filling system is more secure and effective. A visible check of the cylinder is needed before refilling. Washing and drying are also conducted before filling if necessary. To avoid gas leakage from cylinder valve "O" ring must be checked before gas filling, if it is missing in valve must put it. After putting the cylinder body weight, modern machine carousel runs to fill the LP gas in the cylinder. The automatic carousel machine can fill several cylinders at a time. Cylinder checked by automatic weight checking scale to be ensured filling the stipulated value. After this to check the valve leak of LPG filled cylinder for security and safety. If all the process is positive, it is needed to put a safety cap on the cylinder valve and attach the thermo-sleeve for more safety. Then the filled cylinders are kept in the storage for distribution. The Personal Protection Equipment's (PPEs) is must to wear during filling the cylinder.

Improvement proposal to increase performance by applying redesign of stations and work methods together with a preventive maintenance plan in a LPG bottling machine
