摘要： A process for reducing the energy consumption of a distillation column is disclosed. The process includes drawing off an intermediate vapor stream from the rectification section of the distillation column. The vapor stream is compressed and the heat in the vapor stream is exchanged with a portion of the liquid bottoms stream. The heat transfer condenses a portion of the vapor stream, while vaporizing the liquid bottoms stream.

摘要： A process is presented for the separation of a hydrocarbon mixture having less than 50% of the light component in the feedstream. The process provides an energy efficiency through drawing off a vapor stream from the rectifying section of a distillation column, and using recompression of the vapor to provide a portion of the heat for reboiling a portion of the bottoms stream exiting the stripping section of the distillation column.

摘要： Processes for controlling afterburn in a reheater and loss of entrained solid particles in reheater flue gas are provided. Carbonaceous biomass feedstock is pyrolyzed using a heat transfer medium forming pyrolysis products and a spent heat transfer medium comprising combustible solid particles. The spent heat transfer medium is introduced into a fluidizing dense bed. The combustible solid particles of the spent heat transfer medium are combusted forming combustion product flue gas in a dilute phase above the fluidizing dense bed. The combustion product flue gas comprises flue gas and solid particles entrained therein. The solid particles are separated from the combustion product flue gas to form separated solid particles. At least a portion of the separated solid particles are returned to the fluidizing dense bed.

摘要： A distillation column is disclosed. The column includes a plurality of rectification zones and corresponding stripping zones. Each rectification zone is linked to a heat pump or a stage of a heat pump. Overhead material from the top rectification zone is compressed and used to heat bottoms liquid from the bottom stripping zone. Similarly, overhead material from a lower rectification zone is compressed and used to heat liquid taken from the uppermost or top stripping zone. Optionally, overhead material from a middle rectification zone is compressed and used to heat liquid from a middle stripping zone. A single multiple stage heat pump compressor may be utilized as opposed to a plurality of heat pumps. Because the heat exchanger from each rectification-stripping zone pair has a lower duty, economical stab-in heat exchangers may be utilized.

摘要： An apparatus is presented for contacting a bed of particulate material with a cross flowing fluid, which maintains the bed of particulate material within a retention volume. The apparatus includes partitions for retaining particles, with openings disposed within the partitions. The openings are covered by louvers that extend above the edges of the openings to prevent solid particles from spilling through inlet openings, and the design prevents the loss of particles through the openings during cooldown of the apparatus.

摘要： The invention provides a process and system for regenerating a solvent used to remove carbon dioxide from feed gases, such as natural gas and synthesis gas. The invention employs one or more hydraulic turbochargers to transfer energy from a higher energy solvent stream to a lower energy solvent stream. This provides for a significant reduction in operating expenses.

摘要： Disclosed is a mixer-distributor-collector apparatus for use between beds of solid particles in a fluid-solid contacting vessel. The apparatus includes a solids retaining screen, fluid deflector, passageway, fluid distributor, and flow manipulator. The flow manipulator is a device such as a honeycomb, porous solid, perforated plate, screen, or grid having an open area greater than the open area of the fluid distributor and is located below and spaced apart from the fluid distributor. The apparatus improves the fluid flow characteristics by minimizing or eliminating fluid velocity jets and/or other turbulence which can disturb the downstream particle bed. In an exemplary application, the invention finds use in simulated moving bed (SMB) adsorptive separation processes.

摘要： An apparatus is presented for the mixing of a feed fluid with a process fluid between two adsorbent beds. The apparatus creates a space for mixing and redistributing a fluid mixture between the two adsorbent beds, where a process fluid is received from the upper adsorbent bed, and a distributor box passes the feed fluid to space between the adsorbent beds and mixes the feed fluid with the process fluid. The mixture is then redistributed and passed through to the lower adsorbent bed.
