They have a lot of good stuff in their brochures.
In principle, what you want is equal distribution - low pressure drop in the headers, some pressure drop across the drips, so that all drips get equal amounts of liquid.

Marcelo,
Be careful. This is not the type of design I think you should attempt unless you've had significant experience with this sort of thing in the past. Your posting suggest otherwise. It would make little sense for you to attempt to implement a design that failed to properly irrigate the packing below. Different packings require differing irrigation rates. It is important that a good design provide the proper rates and do so efficiently. Should your design not adequately cover the packing, you would render your system ineffective. For example, if your design allowed "holidays" or areas that were not well irrigated, then there could be dry paths through the packing. Those paths would not be available for mass and heat transfer, defeating the intended purpose. Over irrigating some areas is also a problem since those areas might flood. In my opinion, this is a task best left to those who will guarantee the results.
