Abstract:
Methods and apparatus for controlling a characteristic of a cement slurry at a cementing unit, including regulating a characteristic of the cement slurry employing a closed loop feedback arrangement in the cementing unit, and adjusting a gain of the closed loop feedback arrangement in response to sampling an error of the characteristic.
Apparatus and methods for vaporizing liquid nitrogen at sufficient pressure, temperature, and volume to enable a single mobile pumper to meet the needs of many industrial applications. The dual-mode nitrogen pumper of the present invention utilizes a reciprocating pump and heat from the engine coolant and exhaust stream of an internal combustion engine, as well as heat from hydraulic fluid used to load the engine, and transfers that heat to liquid nitrogen pumped through a first heat exchanger and a second, internally-fired heat exchanger is provided to transfer heat to liquid nitrogen pumped through a second heat exchanger. The temperature of the hydraulic fluid is maintained, and the temperature, pressure, and flow rate of the vaporized nitrogen is controlled, by balancing the engine load against the nitrogen pumping rate.

Abstract:
Apparatus and methods for vaporizing LNG while producing sufficient volume of compressed natural gas at sufficient pressure to meet the needs of internal combustion engines, gas turbines, or other high consumption devices operating on natural gas or on a mixture of diesel and natural gas. The LNG vaporizer of the present invention incorporates a reciprocating pump to provide vaporized LNG to an output at rates and pressures as required by the particular application. The heat rejected into the engine coolant and the exhaust stream from an artificially loaded internal combustion engine, as well as the hydraulic heat resulting from artificially loading the engine, is transferred to the LNG as the LNG passes through a heat exchanger. Exhaust heat is transferred to the engine coolant after the coolant passes through the heat exchanger.
