Abstract: A system and method for recovering high-quality biomethane (RNG) from biogas sources is provided. The gas stream is compressed and liquids are separated from the gas stream at elevated pressure and reduced temperature. The compressing is performed using a plurality of compressors operating in parallel with common control set points. The system and method improve upon conventional practices and yield a biomethane product which meets strict gas pipeline quality specifications. Additionally, the system and method are an improvement to the overall methane recovery efficiency for biogas processing facilities.

Abstract: Network marketing compensation systems and methods that have been modified to include compensation for those that are not initially in the network are described. In particular, this application describes compensation methods that include creating a network compensation system for sales of products, the system containing a unilevel distribution network with at least five levels of distributors, allowing an affiliate to recommend a product to a customer, allocating a position in the network to the affiliate, and distributing compensation under the system to the affiliate and the distributor in near real time upon purchase of the product by the customer. These compensation systems and associated methods have a great potential to increase involvement by customers (and others outside the network like an affiliate) that otherwise might not be attracted to it. Other embodiments are described.
