Unfortunately their website links to the Olga program don't appear to be working yet. Maybe their phone number works.

For example if you will receive 1000 bbl slugs, say once every 4 or 5 days, and you can only schedule one 40,000 gal truck a week, you need to make a slug catcher with at least a 2000 bbl capacity + some volume for a safety factor for truck delays or a catching a little bigger slug than you planned on, so say a slug catcher of about 3000 bbls capacity should do.

We typically drop the fluids into a tank first. This way the the you only need to design a slug catcher for one slug, then dump it a rate fast enough to empty it before the next slug. Your storage tank will now be a low pressure vessel and adjustable in size easily to compensate for liquid removal.
Here's the difficult part todat. EPA and VRU economics. All those liquids will empty from a slug catcher and flash off money and EPA noncompliance. Now you have to size a VRU. The VRU is a function of the rate you dump liquids from the slug cather to the storage tank. Now you will have to find the equalibrium balance between the VRU, Slug catcher and storage tank.
Simply put, you could put in the MOASC and have a 2HP VRU that runs 24/7 or you could put in a 10 BBL slug catcher witha 8" dump valve and a 100 HP VRU that runs 5 seconds and shuts down until the next slug comes in.

Trucking is still pretty common in a lot of the worlds oil fields, but no matter, it was simply an example of some type of a scheduled downstream processing event. Substitute dumping it to a VRU if you like.
