摘要： The invention generally relates to the use of liquid nitrogen to displace air, or other water and/or oxygen containing atmospheres, from containers prior to filling with a highly sensitive product. The process in general has two steps: a) depositing a volume of liquid nitrogen into the cavity of an empty container and b) applying a vacuum to the cavity of the container. The vacuum will accelerate vaporization and thereby shorten the liquid nitrogen vaporization time frame. This procedure results in a highly effective one step de-oxygenation and/or de-humidification of the container cavity. Further, the evacuation ensures complete liquid nitrogen vaporization prior to product filling.

摘要： A fermentation process uses substantially pure oxygen. The oxygen is the only reactive gas which is injected into a fermentation vessel. The oxygen is moved through the vessel solely by its own pressure. The process can be used with both mechanically-agitated and air-lifted fermenters. The mechanically-agitated fermenter includes an analyzer for measuring oxygen concentration in the exhaust line, and adjusting the flow of fresh oxygen into the vessel accordingly. In the air-lifted fermenter, an analyzer measures the oxygen concentration in the head space of the vessel, and operates valves which either recycle the gas from the head space, or vent that gas to the outside, according to the measured concentration. A stream of nitrogen is periodically injected into the vessel to drive out carbon dioxide and other gases, to control the pH of the fermentation medium. The present invention substantially improves the efficiency of a commercial fermentation process.

摘要： An improved fermentation device and method uses a combination of substantially pure Oxygen as the Oxygenation gas and a separate air (or other Oxygen reducing gas) purge through the headspace of a fermentation device. The air injection and air purge vent line are configured to maintain a backpressure within the headspace. The air purge permits improved oxygen utilization and increases safety through dilution and removal of ammonia gas emitted during fermentation.

摘要： Dispositif et procédé d'élimination d'un sous-produit du biodiesel issu d'une étape de transestérification, ledit sous-produit étant ou bien un alcool, notamment méthanol ou éthanol, ou bien de l'eau, comprenant une colonne de strippage à pression atmosphérique reliée préférentiellement à un échangeur de type « piège cryogénique ». L'invention traite aussi d'un procédé de purification du biodiesel issu d'une étape de transestérification ainsi que d'une installation de production du biodiesel incluant ledit dispositif et permettant la mise en oeuvre desdits procédés.
