CNG Cooler is a heat exchanger in CNG Plant System which has function to reduce CNG temperature. CNG (Compressed Natural Gas) is natural gas which compressed by gas compressor from normal pressure up to certain high pressure. CNG Plant is gas storage and supply facility for PLTGU when it work at peak load hours. CNG Cooler reduce temperature of CNG which out from gas compressor before saved in storage utility which purpose to avoid over heating in the next process, increase durability of the next process utility, and make gas storage utility design easy.

This discussion paper is based on a preliminary design and is not to be construed or interpreted as being a suitable basis for adoption as a final design for natural gas storage facilities or marine vessels. The gas storage concepts were developed as a basis for project budgeting, further design studies such as HAZID/HAZOP/FEMA, and for review/comment by Classification Societies and Regulatory Authorities as a precedent to further design development.

Abstract The use of high-pressure vessels for the purpose of storing gaseous fuels for land based transportation application is becoming common. Fuels such as natural gas and hydrogen are currently being stored at high pressure for use in fueling stations. This paper will investigate the use of autofrettage in high pressure cylinders and its effects on the life of a vessel used for gas storage. Unlike many high-pressure vessels, the life is controlled by fatigue when cycled between a high pressure near the design pressure and a lower pressure due to the emptying of the content of the vessels.

A theoretical study was conducted to investigate the cooling effect of throttling compressed natural gas during the pressure regulation process. The concept of using this effect in cooling down the induction air was investigated. A thermodynamic model was developed for a typical fuel delivery system used on a vehicle fueled with compressed natural gas. The model was based on a set of integral conservation laws applied to each component of the fueling system. Several heat exchanging arrangements between the throttled gas and the inlet air were examined. The effect of the added heat exchanger on engine delivery ratio was examined for different engine sizes as well as for different operating conditions. An increase of 1 to 2.5% in engine delivery ratio was predicted due to the added heat exchanger.

Reduce the pressure and reheating CNG, created a tool called a pressure reducing system (PRS) which consists of a pressure reducing regulator, heating CNG or we call this section with heat exchanger and measuring tools or gas meter. In connection with this task, will be discussed on the heat exchanger in the heat of this CNG. In this study, a survey was conducted on the heat exchanger Pressure Reducing System (PRS) is installed with a capacity of 200 m3/h, while the use of CNG for the production process is 150 m3/h. CNG temperature after coming out of the PRS read on the thermometer is at 50ºC. From these data it can be concluded that the heat exchanger is greater than the required capacity. In order to get heat exchanger in accordance with the capacity of 150 m3/h will be redesigned according to the capacity. From the data obtained it can be concluded that the pressure reducing system capacity greater use of capacity will value of higher effectiveness at about 90%. As for usage as needed obtained effectiveness of 70%. The advantages that can be drawn is that the efficiency in terms of construction materials and a smaller space than the existing PRS.

ABSTRACTAn apparatus to measure phase equilibria under pressure is described. The composition of the gas phase was determined using a high pressure, high temperature sampling cell. We have found that compressed natural gas is a very good solvent of hydrocarbons. A possible application of this study is the understanding of processes which lead to migration of oil and the location of oil and gas fields.
