“…Since the entire BOG system is a dynamic operation and never really at a steady state, dynamic simulation is a powerful and effective tool to analyze the system. Figure 19 shows simulation conducted by Shin et al [4] depicting the interaction between tank pressure and the number of BOG compressors deployed.…”

“…This paper discusses the ways and means of increasing the capacity of the plant and/or reducing the operational costs of the facility by improving the management of BOG. Most publications in the past have focused on regasification terminals [3][4][5][6][7][8][9][10][11], and while this paper focuses on liquefaction, several of the concepts would apply to regasification and multidirectional terminals. The paper also addresses the range of compression machinery available and the range of typical parameters found in industry.…”

This paper discusses complexities and challenges of managing boil off gas (BOG) in liquefied natural gas (LNG) liquefaction plants. Most publications in the past have focused on regasification terminals and have not addressed the area of liquefaction plants. The paper discusses the generation and management of BOG and the associated networks and machinery to manage it. BOG options available for both Greenfield plants and in debottlenecking situations are covered. The advantages and disadvantages of different options and compressor systems are covered and the concept of dynamic simulation as an analysis tool is addressed.

“…Other optimization studies relevant to storage terminals are focused on energy efficient operation of compressors used to handle the BOG. Optimal operation of compressors by solving a mixed integer linear programming (MILP) problem which minimizes the total power consumption in a LNG plant has been addressed in recent literature. − A Nonlinear Programming (NLP) model to determine the optimal compressor operations for a refrigeration system in a LNG plant has been proposed. , A dynamic model in ASPEN was used in an MILP formulation to determine the optimal operation schedule of compressors …”

Petroleum products such as propane, butane, liquified propane gas, and liquified natural gas are unloaded from ship carriers through pipelines to storage facilities located 10–12 kms inland. This process is an energy intensive and a time-consuming operation. Unloading at high flow rates results in excessive boil-off gas (BOG) generation in the storage tank thereby resulting in increased cost of pumping the fluid and increased cost of compressing the resulting BOG. If the BOG generated exceeds the capacity of the compressors, then the excess gas has to be flared resulting in loss of valuable raw material, besides the associated environmental damage. But, when low unloading flow rates are employed, it results in longer berthing time of the ship to unload the product thus incurring demurrage. In this paper, efficient ways to minimize the total cost of an unloading operation are explored by solving a generalized simulation optimization model and the results are discussed. The strategies and the results presented in this work are valuable for industrial applications.
