Abstract: Systems, devices, and methods for recovering mixed refrigerant and/or nitrogen within liquefaction systems are provided. The systems, devices, and methods facilitate recovering mixed refrigerant (MR) and/or nitrogen vapor that can leak from a compressor, separating the MR from the nitrogen, and reusing the MR and/or the nitrogen within the liquefaction system. Recovering and reusing MR and/or nitrogen can minimize loss of MR and nitrogen which can lower the total operating cost of a liquefaction system. Additionally, recovering the MR, rather than burning it, can reduce environmental emissions by reducing the amount of MR that is burned.

Abstract: Safety valves (100) accurately control closure and opening of fluid passage through the valve. Valves include a barrier (150) that blocks the fluid until removal only by a high-energy projectile (140). Following removal and opening, the barrier (150) or the projectile (140) can flow through the valve (100), which remains open. Bullets, pneumatic pistons, shot, coilgun pellets and any other forceful projectile (140) may impact and remove the barrier (150). The projectile (140) is actuated with any type of chemical reaction, firing pin, spring release, accelerating circuit, ignition circuit (141). Catchers (160) in the valve envelop or otherwise retain the projectile (140) or barrier pieces and enter the fluid flow of the opened valve (100) without blocking it. Disruptable barriers (150) include strong but breakable glass plates (250), thin steel sheets (350), a rotatable door (450) and other barriers that can withstand potentially over 10,000 psi (69 MPa) of fluid pressure while closing the valve (100). Valves (100) can use circuits (151) to both monitor valve open/closed status and initiate firing the projectile.

Abstract: An insulated solution injector (100) may include an outer tube (102) and an inner tube (104) arranged within the outer tube. The outer tube (102) and the inner tube (104) may define an annular space (103) therebetween, and the inner tube (104) may define a solution space (105) within. The annular space (103) may be configured so as to insulate the solution within the solution space (103). As a result, the solution may be kept to a temperature below its decomposition temperature prior to injection. Accordingly, the decomposition of the solution and the resulting deposition of its constituents within the solution space (105) may be reduced or prevented, thereby decreasing or precluding the occurrence of a blockage.
