Liquefied Gas

Liquefied Petroleum Gas (LPG) ships carry a liquefied gas either pressurized, refrigerated or both at the same time. Due to that, among the other cargo containment solutions on LPG ships, type C tanks may be distinguished: they are independent tanks built as conventional pressure vessels. A single hull design of such ships is common and a question of their crashworthiness arises. In particular, the safety of the cargo may be of concern in the case of high energy collision event. In a previous study, crashworthiness of both common and novel sandwich hull design of an LPG ship was studied. In both cases, cargo tank was damaged. It is the aim of this work to study this damage in detail. An LPG ship and ferry collision event was modeled and studied by the means of nonlinear FEM. Collision parameters were altered to study their influence on the resulting collision damage on both ships. Bi-lobe cargo tank crashworthiness is analyzed and the possibility of cargo spill examined.

Comprehensive residual stress of a 1500m3 liquefied petroleum gas spherical vessel was measured and analyzed after many cracks arised. The results show that the general residual stress was at a high level in the field with cracks as well as the field without cracks. Furthermore, the measurements were taken at the same place to evaluate the effect of the heat treatment after this spherical vessel was re-welded and the integral heat treatment was performed. Meanwhile, the measurement to the stress in the vertical direction with X-Ray was finished after a set of special treatments in the outfield.

This study was conducted based on Davis's extended technology acceptance model (TAM) (1989) and survey data of 486 petroleum and liquefied gas enterprises in Vietnam on their intention to apply using a total quality management (TQM) system. Research results show that factors such as (1) Perception of the effectiveness of TQM; (2) Perception of the effectiveness of the convenience in using TQM; and (3) Perception of the effectiveness of TQM compared to the old system which has a positive impact on the intention to apply the total quality management system in petroleum and liquefied petroleum gas enterprises in Vietnam. Besides, the perception of decision-makers on issues related to quality management in these enterprises also has a direct influence on the perception of the TQM usability and indirect effect of the intention to use TQM application in these enterprises.

The expediency of using vehicles of liquefied petroleum gas as a motor fuel, as com-pared with traditional liquid motor fuels, in particular with diesel fuel, is shown. The advantages of converting diesel engines into gas ICEs with forced ignition with respect to conversion into gas diesel engines are substantiated. The analysis of methods for reducing the compression ratio in diesel engines when converting them into gas ICEs with forced ignition has been carried out. It is shown that for converting diesel engines into gas ICEs with forced ignition, it is advisable to use the Otto thermo-dynamic cycle with a decrease in the geometric degree of compression. The choice is grounded and an open combustion chamber in the form of an inverted axisymmetric “truncated cone” is developed. The proposed shape of the combustion chamber of a gas internal combustion engine for operation in the LPG reduces the geometric compression ratio of D-120 and D-144 diesel engines with an unseparated spherical combustion chamber, which reduces the geometric compression ratio from ε = 16,5 to ε = 9,4. The developed form of the combustion chamber allows the new diesel pistons or diesel pistons which are in operation to be in operation to be refined, instead of making special new gas pistons and to reduce the geometric compression ratio of diesel engines only by increasing the combustion chamber volume in the piston. This method of reducing the geometric degree of compression using conventional lathes is the most technologically advanced and cheap, as well as the least time consuming.

The present research aims to analyse diffusion flame in a tube type burner with Liquefied petroleum gas (LPG) as a fuel. An experimental investigation is performed to study flame appearance, flame stability, Soot free length fraction (SFLF) and CO emission of LPG diffusion flame. Effects of varying air and fuel velocities are analysed to understand the physical process involved in combustion. SFLF is measured to estimate the reduction of soot. Stability limits of the diffusion flame are characterized by the blowoff velocity. Emission characteristic in terms of CO level is measured at different equivalence ratios. Experimental results show that the air and fuel velocity strongly influences the appearance of LPG diffusion flame. At a constant fuel velocity, blue zone increases and the luminous zone decreases with the increase in air velocity. It is observed that the SFLF increases with increasing air velocity at a constant fuel velocity. It is observed that the blowoff velocity of the diffusion flame increases as fuel velocity increases. Comparison of emission for flame with and without swirl indicates that swirl results in low emission of CO and higher flame stability. Swirler with 45° vanes achieved the lowest CO emission of 30 ppm at Φ = 1.3.
