A treatment system for performing a treatment on a patient may include a treatment fluid preparation device having a pump connected by a fluid channel to a reservoir of a source fluid, the pump conveying the source fluid from the reservoir, through a filter, and combining the source fluid with a concentrate by pumping the source fluid with the concentrate to form a treatment fluid in a batch container. The treatment fluid preparation device may have a controller that controls a heater, the pump, and a memory. The controller starts the heater to warm the treatment fluid in the batch container at a time that is responsive to the treatment time stored in the memory. The controller also detects a pressure property of the filter to determine its integrity and outputs an indication of a failed batch if the pressure property indicates the integrity of the filter is insufficient.

An air intake system for directing intake air to an internal combustion engine of a machine is disclosed. The air intake system may comprise an air compressor configured to increase a pressure of the intake air, and a membrane unit downstream of the air compressor and having a membrane with selectivity for siloxanes. The membrane may have a first side and a second side, and the first side may be exposed to a higher pressure than the second side when the air compressor is operating. The membrane may be configured to separate the intake air into a permeate that traverses the membrane from the first side to the second side, and a retenate that remains on the first side. The permeate may have a higher siloxane content than the retenate. The retenate may be directed to the internal combustion engine for combustion.

A process for recovering valuables from vent gas in polyolefin production is disclosed. The process includes a compression cooling separation step, a heavy hydrocarbon separation step, a light hydrocarbon separation step, a N.sub.2 purification step, and a turbo expansion step in sequence. The N.sub.2 purification step comprises a membrane separation procedure. The light hydrocarbon separation step comprises at least one gas-liquid separation procedure. A first gas, which is obtained by the gas-liquid separation procedure and is heated through heat exchange with multiple streams in the light hydrocarbon separation step, enters the heavy hydrocarbon separation step and is further heated; the heated first gas then enters the N.sub.2 purification step; a first generated gas, which is obtained by the membrane separation procedure of the N.sub.2 purification step, enters the heavy hydrocarbon separation step and the light hydrocarbon separation step in sequence, and is cooled through heat exchange with multiple streams in the heavy hydrocarbon separation step and the light hydrocarbon separation step; and then the cooled first generated gas enters the turbo expansion step. The energy consumption of a compressor can be greatly reduced. An external cooling medium with a temperature lower than an ambient temperature is not needed. The purity and recovery of N.sub.2 and hydrocarbons can be improved, which can facilitate reduction of energy consumption of a whole system, an investment, and a material consumption.
