摘要: Methods and apparatus relate to treating fluid to at least reduce selenium content within the fluid, which may be an aqueous liquid and form a feed stream. The treating removes selenium that may be present in compounds, such as selenocyanate, from the feed stream based on adsorption from contact of the fluid with a sorbent. Flowing a gaseous hydrogen sulfide and sulfur dioxide containing stream over a support, such as activated carbon, may provide the sorbent impregnated with sulfur and utilized in the treating of the fluid.

摘要: Synthesis of a support material impregnated with silver sulfide provides a sorbent composition. Generating the silver sulfide relies on reaction of sulfur dioxide and one of hydrogen gas and hydrogen sulfide in presence of the support material following silver loading of the support material. Contacting a fluid stream with the sorbent composition removes heavy metal from the fluid stream.

摘要: Methods and apparatus relate to removing selenium from a fluid. The fluid includes non-selenium constituents that are insoluble at a pH in which the fluid is passed through a sorbent bed in order to remove the selenium. Fouling of the sorbent bed can thereby result due to accumulation of the non-selenium constituents, which are precipitated solid materials. Intermittent washing of the sorbent bed with a heated and alkaline wash dissolves and removes the non-selenium constituents to maintain efficient operation and sustain selenium removal performance.

摘要: A plurality of serial data streams are transmitted on a corresponding plurality of lines at a common frequency in equal groups of symbols. A framing signal composed of groups of symbols corresponding in number to groups of data symbols is transmitted on an additional control line. Each group of symbols in the framing signal includes a majority of symbols capable of representing a first plurality of code words and a second plurality, substantially less than the first plurality, of valid code words, and a minority of symbols which constitute parity check symbols. Each of the valid code words consists of a first sub-group of similar symbols and a second plurality of similar symbols. For some of the valid code words the symbols in the first sub-group are similar to the symbols in the second sub-group. For other valid code words the symbols in the first sub-group are different from the symbols in the second sub-group. The valid code words correspond to groups which represent (a) start of a data packet or block; (b) data/(c) a gap between groups of data; and (d) an idle state. The sequence of groups in the framing signal is monitored by means of a state machine.
