摘要： Processes for separating a solid from a solids-liquids slurry under conditions that prevent ingress of molecular oxygen are advantageous where the presence of molecular oxygen would otherwise reduce efficiencies, contribute to limited product yields, and potentially compromise safe operation of the process or downstream unit operations. Among the various embodiments disclosed herein, is a process utilizing filter columns as solid-liquid separators in combination with crystallization and reslurry unit operations to recover a product component from an initial feed mixture of miscible components. Embodiments of the disclosed processes may include the separation and purification of a product component using a crystallizer in series with a filter column followed by a chemical reactor, using a reslurry drum in series with a filter column, and using a combination of crystallizers and/or reslurry drums in series with at least one filter column. The use of filter columns in such processes is particularly attractive because these columns, when operated under the conditions disclosed herein, limit the undesirable ingress of molecular oxygen into the various process streams, and further improve process efficiencies related to both product component recovery and operating costs.

摘要： Aspects of the subject matter described herein relate to symmetric routing to a private network. In aspects, a remote client may try to connect to an entity of a private network using a non-routable network address. Upon detecting that connectivity is not established or not possible via a given network address, the client may obtain network data associated with a gateway that provides access to the private network and create a virtual interface where the gateway is the next-hop router. After creating the virtual interface, the client may communicate with entities of the private network using the virtual interface of the client. By sending traffic through the virtual interface with a source address having a prefix associated with the gateway, the client may ensure that traffic sent to and from the private network traverses the gateway.

摘要： A process for separating solids from liquids in a filtration zone defined by a higher concentration zone and a lower concentration zone separated by a filter. The process includes the steps of directing a slurry feed comprising a liquid and solids into the higher concentration zone, directing a displacement fluid to the higher concentration zone and passing at least a portion of the liquid through a filter to the filtrate zone, producing a filtrate.

摘要： A pressure swing adsorption process to separate para-xylene and ethylbenzene from C8 aromatics which uses a para-selective, non-acidic, medium pore molecular sieve of the MFI structure type and is operated isothermally in the vapor phase at elevated temperatures and pressures is integrated with crystallization to produce para-xylene product. A fixed bed of adsorbent is saturated with pX and EB, which are preferentially adsorbed, the feed is stopped, and lowering the partial pressure desorbs the pX and EB. The process effluent, which is rich in pX and EB, is crystallized to obtain para-xylene product.
