Vapor recovery system utilizing compression-condensation processes and related methods

Номер: US20120042691A1

Автор: Carol Diane Krumbholz

Принадлежит: Individual

An off gas extraction system cleans common sources of off gas, such as storage tanks and polluted soils. Off gas is extracted, followed by compression and condensation. Compression and condensation produce an off gas that can be reintroduced as a treated gas into the off gas source. Alternatively, a regenerative absorber cleans the treated gas by adsorbing residual chemical vapor and concentrates the removed chemical vapors and reprocesses them. If the treated gas is not reintroduced into the off gas source, conventional scrubbers may used on the back end of the system to produce a final exhaust as prescribed by environmental regulation. Methods of accomplishing the same are similarly provided, including novel methods for degassing storage tanks and treating polluted soils to meet current environmental regulations, as well as green technology and sustainability initiatives.

In a method for adsorptively drying purified biogas and regenerating laden absorbents, foreign matter is not allowed to enter the purified biogas, the content of methane in the gas remains virtually unchanged and the effort involved in regenerating the laden adsorbent is reduced. Drying and regeneration are effected in a closed biogas cycle, wherein separate layers based on silica gel and molecular sieves are used as the adsorbent. The biogas to be dried first flows through the silica gel layer. The adsorbent is regenerated with exclusively heated, dried biomethane having a temperature of up to 150° C. which, after contact with adsorbent, is recirculated to the outflow of purified biogas. After regeneration, the bed is cooled by biomethane, which is subsequently recirculated to the outflow of purified biogas. Methane-containing water accumulating during drying and regeneration is recirculated to the biogas generation and/or purification.

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.
