    Abstract: This invention relates to an ecologically and environmentally friendly mud-gas containment system. Specifically, this invention relates to a mobile device that is capable of receiving waste gas and, in emergency situations, a volume of a mud-gas mixture from a drilling operation. The waste gas is communicated to a removable flare stack through a vent line. The mud-gas is received at a containment vessel. The impact of the mud-gas within the containment vessel separates the mud-gas into mud and waste gas. The mud is collected for recycling and/or environmentally sensitive disposal. The waste gas from the vessel is communicated to the flare stack. Separate removal ports and conduits are used to remove any residual mud or mud-gas from the vent line and/or containment vessel. Excess mud or mud-gas is communicated to an overflow catch tank for removal. The entire assembly is mounted on a mobile skid sized for highway transportation.

  • Patent number: 7766010
    Abstract: A method of providing concentrated oxygen product gas to a patient. The method comprises producing product gas by a vacuum swing adsorption (VSA) process with an oxygen concentrator comprising a plurality of separation columns connected to a vacuum source driven by a motor. Separated product gas is then pumped to a product reservoir. The pressure of the reservoir is monitored and used to adjust the speed of the motor based on the reservoir pressure. The separated gas is then delivered to the patient.

  • Publication number: 20090014368
    Abstract: A mechanical vessel may effectively and simultaneously displace a first undesired gas from within water with a second desired gas, and remove at least one alkaline species and oily matter from the water. The vessel raises the pH of the water and reduces the lime requirement for subsequent lime softening. The vessel receives the water containing the first gas and passes the water through a series of gasification chambers. Each gasification chamber may have a mechanism that ingests and mixes a second gas into the water thereby physically displacing at least a portion of the first gas into a vapor space at the top of each gasification chamber from which it is subsequently removed. There is an absence of communication between the vapor spaces of adjacent chambers. An acid is added to remove the alkaline species, where the first gas is an optional by-product that is also removed.
