Ive been looking around for a process flowsheet diagram of a LNG regasification terminal, but I haven´t found a single one. I dont need a fancy one, just the main equipments. I made the following state of the art PFD (its a joke) with the things I supose are the more important. So if you think that I missed some key equipments like an extra pump (not back-up pumps) or any other compressor please post it.

Thank you

Regards.

Why do you include a "separator" before your vaporizer feed pump? What exactly do you propose to separate?

Why do you connect the suction of the compressor with the "separator"? Do you intend to apply a centrifugal or a positive displacement compressor to feed your product gas line? How do you intend to manage the different compression ratios between the vaporizer output and the separator output?

Give details of what you propose to do because a simple block diagram doesn't address process issues such as what I've pointed out. - or draw a more detailed, P&ID.

I guess that part of the LNG could be vaporized due to heat loss.

Im not trying to design a LNG terminal, the objetive is to make a small dynamic simulation (thats the need of a simple PFD) and show it to a couple of companies in my country (since this companies have simulators, but they just use them for simply steady-state simulations) and try to sell them a simulation according to their plants.
