System and method for producing hydrocarbons from a well

A system for producing hydrocarbons from a well includes an unloading unit that receives fluids from a wellhead. The unloading unit separates the oil and gas, and the oil is pumped to a pipeline. Using the unloading unit and the pump helps to reduce the pressure at the wellhead which helps increase production. The gas separated by the unloading unit is compressed and re-injected into the well to create a gas lift which further helps increase production. Capturing and reinjecting the separated gas for gas lift operations reduces environmental damages associated with conventional unloading unit and pump assemblies. The unloading unit, compressor, and pump are modular for quicker installation and a smaller footprint. After increasing the productive life of a first reservoir, the system can be broken down and reassembled for use at another reservoir.

Method for Liquid Air Energy Storage with Semi-Closed CO2 Bottoming Cycle

A proposed method provides a highly efficient fueled power output augmentation of the liquid air energy storage (LAES) through its integration with the semi-closed CO2 bottoming cycle. It combines the production of liquid air in air liquefier during LAES charge using excessive power from the grid and an effective recovery of stored air for production of on-demand power in the fueled supercharged reciprocating internal combustion engine (ICE) and associated expanders of the power block during LAES discharge. A cold thermal energy of liquid air being re-gasified is recovered for cryogenic capturing most of CO2 emissions from the facility exhaust with following use of the captured CO2 in the semi-closed bottoming cycle, resulting in enhancement of total LAES facility discharge power output and suppressing the thermal NOx formation in the ICE.

Ffwn clean energy power plant

Gravity and hydrostatic pressure are natural forces that have considerable force generating capabilities which can make significant contributions during the operation of a FFWN 24 / 7 / 365, baseload, 100% clean energy power plant. When these natural forces are combined with compressed air in the upper part of an elevated storage tank containing a liquid and the partial vacuum created by powerful pumps to produce a targeted water flow rate velocity of about 31.3 m / s through the entire length of a coiled section of pipe containing one or more helical turbines in each coil that are connected to an external generator, the electricity produced during a power producing cycle by all the turbines / generators when combined will be considerably more than the power ultimately consumed by the pumps to return the highly pressurized water in a ground level tank back to the storage tank utilizing a return tank and simple water displacement.
