The present invention is directed to improvements in storage and delivery systems that allow for rapid fill and delivery of gases reversibly stored in a nonvolatile liquid medium, improvements in delivery and purity of the delivered gas. The low pressure storage and delivery system for gas which comprises:a container having an interior portion containing a reactive Lewis basic or Lewis acidic reactive liquid medium that is reversibly reacted with a gas having opposing Lewis acidity or basicity;a system for transferring energy into or out of the reactive liquid medium; or,a product gas purifier (e.g. a gas / liquid separator); or both.

A gas sampling container (15) capable of obtaining, isolating and transporting samples of gas or other fluid under pressure form. The container (15) further exhibits a plurality of simple, reliable, inexpensive, self sealing, valves (2) which allow introduction, flow through and exit of the gas sample. The container (15) is suitable for taking discrete or serial samples from a gas or fluid flow source and is especially suited for use in automated sampling apparatus. These containers are acceptable for shipment of compressed flammable gases under the regulatory structures of many countries.

The present invention provides a gas generating material having high adhesiveness to a member to be bonded and having a large amount of gas generated per unit time even if it further contains a silane coupling agent. The gas generating material according to the present invention contains a binder resin, a gas generating agent which is an azo compound or an azide compound, and a silane coupling agent having an amino group.

The purpose of the present invention is to provide an injection apparatus and an injection method for a liquid sample for standard gas production, wherein the injection apparatus for injecting a liquid sample present in a liquid state at room temperature into a standard gas container has an improved structure that minimizes the area in which the liquid sample directly contacts the injection apparatus so as to prevent the problem in which the liquid sample is adsorbed into the injection apparatus. Furthermore, another purpose of the present invention is to provide an injection apparatus and an injection method for a liquid sample for standard gas production, in which a step of volatilizing the remaining liquid sample by heating is eliminated during the injection of the liquid sample, thereby preventing the apparatus from being damaged by heating to thereby improve the durability of the apparatus.

The method of storing nitrogen trifluoride includes storing nitrogen trifluoride in a chromium-molybdenum steel vessel manufactured through a deep drawing ironing process. Nitrogen trifluoride stored in this way according to the method of this invention does not deteriorate even after two years or more have passed.

The invention relates to a recovery device, in particular to a tail gas recovery device for liquid chemicals. The technical problem to be solved by the present invention is how to design a tail gas recovery device for liquid chemicals that can recycle the tail gas when using liquid chemicals for experiments or energy utilization. In order to solve the above technical problems, the present invention provides such a tail gas recovery device for liquid chemicals, comprising: a bottom plate, a mounting frame is connected to one side of the top of the bottom plate; a sliding plate, a sliding plate is slidably connected to the other side of the bottom plate; The trachea, the top side of the mounting frame is connected with a trachea; the joint, one side of the trachea is connected with a joint. The invention recovers the tail gas of the liquid chemical through the cooperation of the air bag, the lifting assembly and the extrusion assembly, so as to realize the effect of recovering the tail gas of the liquid chemical.

The invention discloses a gas-liquid pressure balance regulator and a water draining and gas collecting device with the same, and belongs to the field of gas measurement equipment based on a drainage method. The regulator includes a pressure balance regulator body used for cooperating with the bottom end of a gas collecting measuring cylinder in a sealed mode to conduct drainage and gas collection, the pressure balance regulator body is internally provided with a gas inlet channel used for introducing gas into the gas collecting measuring cylinder, the gas inlet channel contains a capillary tube section, and the gas inlet channel is internally connected with an external one-way valve; the pressure balance regulator body is further internally provided with a water storage cavity and a drainage channel used for draining water drained by the gas collecting measuring cylinder into the water storage cavity; one side of the water storage cavity is further provided with a water outlet nozzle. According to the gas-liquid pressure balance regulator and the water draining and gas collecting device with the same, a design concept of not adopting conduits is adopted, namely collection and measurement of gas on the basis of the drainage method are achieved without adopting conduits for connection; the high precision is ensured, and meanwhile, the portability and operability of the regulator are improved; moreover, by using water in the water storage cavity to cool high-temperature gas, interference caused by vapour on experimental precision is eliminated, and suck-back or siphonage phenomena resulted from unstable air pressure in a pipeline or excessively high gas flow rate can be avoided.

The present document describes a process for production of hydrogen gas (H2) from fermentation of crude glycerol with a hydrogen producing microorganism in a bioreactor. The process comprises the step of introducing a volume of crude glycerol in a fermentation mixture which comprises a fermentation medium comprised of crude glycerol and hydrogen producing microorganisms under a fermentative hydrogen production condition, and then removing a volume of the fermentation mixture equal to the second volume of the crude glycerol, to maintain constant the total volume of the fermentation mixture.
