|20130112080||System, Apparatus and Method for Degassing a Container - A variety of systems, apparatus and methods for degassing a container are described. A system comprises at least one input being configured to be coupled to a container to be degassed. A fluid output is configured to return fluid to the container. A degassing vessel comprises a top, a bottom, gas/fluid input being coupled to the at least one input, a degassed fluid output disposed proximate the bottom, and a gas output at the top. A pump system is coupled to the fluid output and the degassed fluid output. The pump system is configured to be operable for inducing a pressure differential between the degassing vessel and the container to induce a flow from the container to the degassing vessel and to return fluid to the container. A degas valve is coupled to the gas output for enabling entrained gas in the degassing vessel to be vented.||05-09-2013|
|20110272133||Systems and Methods for Delivering Gases through a Single Manifold for Remediation - Systems and methods for delivering gases through a single manifold for remediation techniques are described. A system comprises a plurality of gaseous sources and a manifold comprising a plurality of inputs being operable for receiving gases from the gaseous sources, and a plurality of outputs being configured to supply gases to a plurality of injection wells for soil and groundwater remediation. The manifold is further operable for being controlled to select a one of the plurality of inputs and to select a one of the plurality of outputs. A programmable controller is operable for controlling the manifold to select one or more combinations of the plurality of inputs and to select one or more combinations of the plurality of outputs during programmed time intervals.||11-10-2011|
