A method for facilitating removal of mercury from a primary fluid stream of interest which is contaminated with organically-bound, elemental, and ionic mercury species. The stream is analyzed to establish the relative content of the organically-bound, elemental, and ionic mercury species present therein by forming a diverted side stream from the primary stream, and passing the side stream successively through three in series filter stages, the first captures organically bound mercury, the second captures elemental mercury, and the third captures ionic mercury. The side stream flow through the filter stages is continued for a predetermined period, and upon conclusion of the period the quantity of mercury collected at each of the filtration stages is determined. This data is then utilized to determine the capacity of the three different filtration stages required to reduce the mercury content in the mam stream to a desired level.

Номер: US20120222555A1
Автор: Daniel P. Leta, Harry W. Deckman, Ramesh Gupta
Принадлежит: ExxonMobil Research and Engineering Co

A gas separation process uses a structured particulate bed of adsorbent coated shapes/particles laid down in the bed in an ordered manner to simulate a monolith by providing longitudinally extensive gas passages by which the gas mixture to be separated can access the adsorbent material along the length of the particles. The particles can be laid down either directly in the bed or in locally structured packages/bundles which themselves are similarly oriented such that the bed particles behave similarly to a monolith but without at least some disadvantages. The adsorbent particles can be formed with a solid, non-porous core with the adsorbent formed as a thin, adherent coating on the exposed exterior surface. Particles may be formed as cylinders/hollow shapes to provide ready access to the adsorbent. The separation may be operated as a kinetic or equilibrium controlled process.

Catalytic adsorbents obtained from municipal sludges, industrial sludges, compost and tobacco waste and process for their production

Номер: US20130102456A1
Автор: Teresa J. Bandosz
Принадлежит: Research Foundation Of City University of New York

Industrial waste derived adsorbents were obtained by pyrolysis of sewage sludge, metal sludge, waste oil sludge and tobacco waste in some combination. The materials were used as media to remove hydrogen sulfide at room temperature in the presence of moisture. The initial and exhausted adsorbents after the breakthrough tests were characterized using sorption of nitrogen, thermal analysis, XRD, ICP, and surface pH measurements. Mixing tobacco and sludges result in a strong synergy enhancing the catalytic properties of adsorbents. During pyrolysis new mineral phases are formed as a result of solid state reaction between the components of the sludges. High temperature of pyrolysis is beneficial for the adsorbents due to the enhanced activation of carbonaceous phase and chemical stabilization of inorganic phase. Samples obtained at low temperature are sensitive to water, which deactivates their catalytic centers.

Flexible adsorbents for low pressure drop gas separations

Номер: US20180036673A1
Автор: Narasimhan Sundaram
Принадлежит: ExxonMobil Research and Engineering Co

In various aspects, apparatuses and methods are provided for low pressure drop gas separations. In PSA processes, where there are large swings in pressure and corresponding swings in fluid velocity through the adsorbent, mechanical stresses during pressure cycling are of considerable concern. When that pressure is relieved in a lower pressure portion of the cycle, the high velocity of gas moving through the adsorbent bed can erode, strip away, or otherwise damage the channels within the adsorbent. Provided herein are methods which utilize flexible boundaries between adsorbent beds that are operated out of phase with one another. The flexible boundaries permit an increase in void space through the adsorbent during high pressure stages of the cycle and a decrease in void space through the adsorbent during low pressure stages of the cycle.
