Provided is a hollow fiber membrane module that exhibits excellent durability even when a chemical such as a radical polymerizable compound is used for a separation or mixing process. Also provided is a method for producing the hollow fiber membrane module in a highly productive manner. More specifically, there is provided a hollow fiber membrane module at least including a tubular body, a cap, a hollow fiber membrane, and an end seal portion, wherein at least a liquid contacting portion of the end seal portion is sealed with a cured product of a curable resin composition including an epoxy resin, and wherein the epoxy resin includes a polyglycidyl ether of a polycondensate of an aromatic compound containing a phenolic hydroxyl group and an aromatic compound containing a formyl group and a phenolic hydroxyl group, and there is provided a method for producing the module.

A system for filling multiple sterile containers includes a filter with an inlet port and multiple outlet ports, the outlet ports being pre-attached to sterile containers by respective filling lines of each container. Each container has an interior and each of the respective filling lines are connected to a respective container interior. The respective filling lines are sealed to the outlet ports and the containers such that the container interiors are isolated from an external environment except the inlet port, via the filter, forming a combined interior volume which is sterile. A container that is connectable to an outlet port the system has a bladder, a first tube and a second tube connected to the bladder, and a sterilizing filter. The container, the first tube and the second tube, and the sterilizing filter are sterile before water is flowed through the sterilizing filter into the bladder.

The invention generally relates to a process for purifying a hydrogen gas for use in a fuel cell. The process involves taking a hydrogen feed stream from a high-pressure tank and passing it through a purifier comprising an adsorbent to provide a purified hydrogen stream which is sent to a fuel cell. A particular adsorbent which can be used is a metal-organic framework composition. The adsorbent can be housed in a device such as a canister or cartridge having an inlet and outlet port.

A microfluidic assembly can include a first microchannel substrate defining one or more first microchannels, a second microchannel substrate defining one or more second microchannels. The assembly can further include a membrane positioned between the first and second microchannel substrates and comprising a first polymeric layer, a second polymeric layer, and one or more graphene layers disposed between the first and second polymeric layers. At least a portion of the first microchannels can overlap at least a portion of the second microchannels such that, when a first fluid is present in the first microchannels and a second fluid is present in the second microchannels, the first fluid and the second fluid contact opposite sides of the membrane.

A distillation station for separating components of a liquid mixture, comprising a vertical distillation column split into individual separation stages by fittings and which is further split by the liquid mixture feed into a stripping chamber and an enriching chamber, wherein in the stripping chamber the lower boiling fraction of vapor from the fluid mixture rising from a column sump comprising an evaporator is stripped, and in the enriching chamber the vapor is enriched with the lower-boiling fraction, which is withdrawn from a return fluid produced due to the vapor drawn from the column head being precipitated at least partially in a condenser and returned to the rectifier column, and the return liquid and the liquid mixture preferably fed between two separating stages being routed to the fittings vertically connected in sequence. In the process, each of the fittings comprise at least one liquid channel, which is separated at least partially from the vapor chamber of the distillation column by a two-sided vapor-permeable, liquid-tight membrane wall.

Embodiments provide a filter with a generally rectangular, non-cylindrical profile. The filter may have multiple pleat packs positioned between pleat covers that define regions and flow channels in a cavity of the filter body. The pleat covers have openings that allow a fluid to flow through the multiple pleat packs via parallel flows or series flows. End caps bonded to the body define flow passages for directing the fluid from an inlet to an outlet via the pleat packs for series or parallel filtration. The pleat packs may be made of the same or different materials and may be configured with the same or different heights based on flow requirements. A cage or a separator may be positioned between the pleat packs. The pleat packs may be made of a continuous pleated membrane with bridges defining a space between the pleat packs to accommodate the cage or separator.
