A method according one embodiment includes at least one of bubbling dried air through a hydrogen peroxide solution in a container for producing a first hydrogen peroxide vapor, and passing dried air from the moisture trap into a headspace above the hydrogen peroxide solution in a container for producing a second hydrogen peroxide vapor. Additional systems and methods are also presented.

A device for grinding and reducing food waste to be disposed of in sewage systems. The device eliminates disagreeable odours by flooding the grinding chamber with water using a swivel plug that retains a gap of fresh water from the last use of the tap. The fresh water serves as a barrier to odors by creating a partition, isolating the dirty water in the grinding chamber. The matter to be grinded is segmented and torn up several times by a grinding apparatus made of cutting blades while it swirls in the water until it is reduced to particles small enough to pass through openings in a spherical grid. The device can be adapted to different uses: residential, commercial or industrial.

The present disclosure provides a gas-liquid flow separation system configured to separate a fluid stream containing both gas and liquid components into separate gas and liquid streams. The separation of the components permits the collection of data relating to the volume of each stream. In some embodiments, the separation system provides for the subsequent recombination of the streams in a homogeneous mixture for processing by downstream facilities. Also, the present disclosure provides a manifold system configured to receive fluid streams from a plurality of sources, combine the streams into a single blended stream containing both gas and liquid components. Subsequently, the system provides for separation of the gas from the liquid components and optional recombination of the same.

A method for multi-horizon forecasting of gas-liquid slug flow is provided. Field data for a well is obtained. The field data comprises a plurality of features. The plurality of features is correlated across a set of historic data to generate time series data for each of the plurality of features. The time series data is processed by a machine learning model to generate a multi-horizon forecast of a flow pattern for the well, and the output is presented.

An apparatus for the treatment and transformation of municipal wastewater sludge or any other organic putrescible matter into biogas and liquid fertilizer by methanation. Several consecutive floating cylindrical bioreactors almost totally immersed in water, are bathing longitudinally in a thermally insulated basin to maintain set temperatures, mixing their contents by revolving on themselves by the action of air ejected from a conduit underneath them, engaging all elements in a collective momentum, from a multiplied force, because of the constant free power of each air bubble lodged in exterior buckets and grouped as a lifting force. The gas produced by methanation of the organic waste furnishes a source of heat and its pressure is used for the functioning of the whole apparatus, including several types of pumps, valves, and a new model of steam engine. A network of hoses is provided to bring the fertilizer to the farmlands.

A method of operating a submersible pumping system includes the steps of placing the pumping system in a normal mode of operation and then detecting the possible presence of a gas slug in proximity to the pumping system by measuring a decrease in the load on the motor. Once the possibility of a gas slug has been detected, the method continues by placing the pumping system in a reduced speed cycle. The pumping system is kept in the reduced speed cycle until the absence of a gas slug in proximity to the pumping system is detected by evaluating two independent conditions within the pumping system.

A dispenser for dispensing liquid material while attenuating the liquid material and controlling the pattern of the liquid material with process air has a manifold with a plurality of process air passages for providing the process air to one or more liquid dispensing modules. The pressure of process air to one or more of the modules may be separately controlled to be different from the pressure provided to other modules on the dispenser. Accordingly, the air pressure provided to each module can be optimized to accommodate a particular dispensing die.

Methods and systems are provided for controlling operational parameters of a CO.sub.2 compression surface facility or pipeline in order to maintain a CO.sub.2 stream having impurities flowing in the pipeline in a liquid or supercritical phase. Sensors may be provided to sense whether the flow is single-phase or two-phase flow, and feedback provided to adjust the pressure and/or temperature at the pipeline inlet. The system is preferably optimized to limit power consumption and/or cost.

Multiphase flowmeters and related methods having asymmetrical flow therethrough are disclosed. An example method includes configuring an inlet manifold, a first flowline, and a second flowline to decrease a gas fraction in a first fluid flow through the first flowline and increase a gas fraction in a second fluid flow through the second flow line; flowing the first fluid flow through the first flowline and flowing the second fluid flow through the second flow line; and determining at least one of 1) a first water liquid ratio of the first fluid flow through the first flowline; 2) a first liquid flow rate of the first fluid flow through the first flow line; or 3) a first gas flow rate of the first fluid flow through the first flow line.

A system for dewatering a subsea gas pipeline includes a pig launcher at the pipeline's upper end, which may be at or near the sea surface, and a pig receiver at the pipeline's lower end, which may be at or near the sea floor. A multiphase pump unit is deployed at the pipeline lower end and is configured to provide sea water suction to aid in a pig train being forced downwards through pipeline. The multiphase pump is configured to handle some amount of gas leaking around the pig train. A choke system may allow sea water to enter the flowline, thereby lowering the gas volume fraction (GVF) and preventing the GVF from exceeding the ability of the multiphase pump. For deeper water applications, a second pump may be provided in series that may be a single pump if positioned downstream of the multiphase pump.
