Vertical Skimmer Horizontal Skimmer
Advantages

Sand and other solid particles can be drained off the bottom more efficiently

Less susceptible to high level shutdowns due to liquid surges
Efficient at water treating because the oil droplets do not have to flow countercurrent to the water flow
Disadvantages Since oil droplets must rise upward counter-current to the downward flow of the water, the process is more complex

Does not drain sand and particles successfully

Liquid surges can trigger an internal wave
