Abstract
In this research, the design principles of double-walled metal-metal (ethylene / ethane) storage tanks are extracted, focusing on the selection or proposal of super-insulation of double-walled middle perlite base. Presenting the results of research on companies with technology to design and manufacture liquefied gas storage tanks in the world, extracting basic concepts and studying the general and available principles of designing double-walled metal-metal tanks and providing sample calculations to explain the application of tank design rules and The software codes related to performing these calculations constitute the first two parts of this research. Then the principles of design and construction of concrete tanks and comparison from the macro perspective of metal and concrete tanks will be presented. The following are the basic concepts in liquefied petroleum gas storage tank insulation. Also, by performing insulation design calculations, the optimal insulation thickness is determined and related software codes are compiled and presented. In the final phase of this research, alternative studies for the insulation system will be studied and in order to prove the suitability of the introduced alternative insulations, thermal-economic analysis with an optimization perspective and including sensitivity analysis will be presented. The results of the analysis show that although the proposed insulation system as an alternative requires a little more initial cost to implement, in less than a year it reaches the point of investment failure and according to It will be much more durable and economically much more durable than conventional insulation systems.
