Unloading of lng from lng tank

Номер: US20120017608A1

Disclosed is a liquefied natural gas storage apparatus. The apparatus includes a heat insulated tank and liquefied natural gas contained in the tank. The tank has heat insulation sufficient to maintain liquefied natural gas therein such that most of the liquefied natural gas stays in liquid. The contained liquefied natural gas has a vapor pressure from about 0.3 bar to about 2 bar. The apparatus further includes a safety valve configured to release a part of liquefied natural gas contained in the tank when a vapor pressure of liquefied natural gas within the tank becomes higher than a cut-off pressure. The cut-off pressure is from about 0.3 bar to about 2 bar.

Tank and manufacturing method thereof

Номер: US20120024745A1
Принадлежит: Toyota Motor Corp

There are disclosed a tank having a structure which achieves both a burst strength and a fatigue strength, and a manufacturing method of the tank. In order to realize this, in a tank comprising a liner, and an FRP layer including a hoop layer and a helical layer formed by winding fibers around the outer periphery of the liner, at least an innermost helical layer is formed as a smooth helical layer. When the smooth helical layer, i.e., a helical layer which does not have any unevenness or which has only little unevenness is formed, the unevenness can be prevented from being transferred to the hoop layer adjacent to the helical layer. When structural bends (undulations) of the fibers of the hoop layer are suppressed, a fatigue strength of the fibers themselves can be enhanced.

CONTROL CIRCUIT FOR STOPPING THE FLOW OF FLUID IN A PRIMARY CIRCUIT, AND RELATED METHODS AND DEVICES

Номер: US20190001282A1
Автор: Parks Richard E.
Принадлежит:

A control circuit for automatically stopping the flow of a gas in a primary circuit, includes a valve, a sensor and a controller. The valve is couplable with a primary pressure-regulator that controls the flow of another gas in a primary circuit. The valve has an inlet operable to receive a gas and an outlet operable to distribute the gas. When the valve is open the pressure of the gas at the valve's outlet equalizes with the pressure of the gas at the valve's inlet. When the valve is closed the pressure of the gas at the valve's outlet is prevented from equalizing with the pressure of the gas at the valve's inlet. The sensor is positionable in the primary circuit and operable to sense a parameter of the flow of the gas in the primary circuit and generate a signal that represents the sensed parameter. The controller is operable to receive the sensor's signal and, in response to the signal, direct the valve to close if the parameter of the flow of gas in the primary circuit lies outside of a predetermined range, to change the pressure of the gas at the valve's outlet. With the control circuit one can block the flow of gas/air toward an injector if the injector becomes stuck in the open position. If the injector becomes stuck in the open position, the primary circuit could consume much more gas/air than required, which could cause the system to consume excess energy and excessively mix the contents. 1.
