The disclosed invention relates to a method for restarting a synthesis gas conversion process which has stopped. The synthesis gas conversion process may be conducted in a conventional reactor or a microchannel reactor. The synthesis gas conversion process may comprise a process for converting synthesis gas to methane, methanol or dimethyl ether. The synthesis gas conversion process may be a Fischer-Tropsch process.

Synthesis gas conversion process

Method for stopping and restarting a Fischer-Tropsch process

A Fischer-Tropsch-based hydrocarbon conversion process involves compressing air in a compressor section of a gas turbine, delivering a portion of the compressed air to a combustor of the gas turbine, delivering a portion of the compressed air to a Fischer-Tropsch hydrocarbon conversion unit, extracting thermal energy from the combustor and delivering it to the Fischer-Tropsch hydrocarbon conversion unit, converting light hydrocarbons into heavier hydrocarbons in the Fischer-Tropsch hydrocarbon conversion unit, and delivering combustion gases from the combustor to an expansion section of the gas turbine. A heat recovery steam generator (HRSG) may also be used to harness waste heat from the expansion section. A conversion system for converting light hydrocarbons into heavier hydrocarbons includes a turbine from which heat energy is removed and used to assist in converting hydrocarbons and whereby greater throughput of the turbine is possible. Waste heat from the expander of the turbine may be recovered with a HRSG.

Hydrocarbon conversion system with enhanced combustor and method

A Fischer-Tropsch-based process and system for converting light hydrocarbons into heavier hydrocarbons uses a plurality of different synthesis gas generators. The process includes preparing a first synthesis gas having a H :CO ratio greater than 2:1; removing a portion of the hydrogen from the first synthesis gas; preparing a second synthesis gas with a CO recycle wherein the second synthesis gas has a H :CO ratio less than 2:1; adding the removed hydrogen to the second synthesis gas to increase the H :CO ratio of the second synthesis gas; and using a Fischer-Tropsch reaction to convert the first synthesis gas and the second synthesis gas to heavier hydrocarbons.

Hydrocarbon conversion process using a plurality of synthesis gas sources

A system for converting lighter hydrocarbons to heavier hydrocarbons has a synthesis gas subsystem for receiving air and light hydrocarbons and producing a synthesis gas; a synthesis subsystem for receiving synthesis gas from the synthesis gas subsystem and producing heavier hydrocarbons therefrom and an aqueous byproduct stream having contaminates; and a stripper subsystem for receiving the aqueous byproduct stream and removing contaminates therefrom, wherein the stripper subsystem includes a concentrator column for concentrating contaminates in an aqueous by product stream, and a stripper column for stripping contaminates from a concentrated aqueous byproduct stream. A method for producing heavier hydrocarbons from lighter hydrocarbons includes the steps of: reacting air and a light hydrocarbon feedstock to produce a synthesis gas; delivering the synthesis gas to a Fischer-Tropsch reactor; using a Fischer-Tropsch reaction in the Fischer-Tropsch reactor to convert the synthesis gas into heavier hydrocarbons; removing contaminates from an aqueous byproduct stream; and wherein the step of removing contaminates from the aqueous byproduct stream includes the steps of: concentrating the contaminates in a concentrator column, and using the light hydrocarbons in a stripper column remove the contaminates from the byproduct stream.

System and method for converting light hydrocarbons to heavier hydrocarbons with improved water disposal

The present invention provides for a crystalline form of trimetrexate either as a glucuronate, acetate, hydrochloride, methanosulfonate or lactate salt, which can be processed galenically as a stable, well-defined solid substance and processes for producing the crystalline forms. Such crystalline forms allow for prolonged stability in storage and for oral and intravenous administration of the drug.

The present invention relates to a sterile, stable vacuum dried crystalline amifostine composition and, optionally, pharmaceutically acceptable excipient(s). Typically, the crystalline compositions of the present invention exhibit enhanced stability at temperatures ranging from about 4.degree. C. to about ambient temperature for a period of at least 2 years relative to existing solid vacuum dried amorphous amifostine preparations. The reconstituted compositions of the present invention are suitable for administration to humans as a radio- or chemoprotecting agent.

A process for the recovery of hydrocarbon vapors from an air-hydrocarbon mixture wherein the inlet air-hydrocarbon mixture is passed to an absorber vessel in which is fed a vacuum flashed liquid hydrocarbon absorbent to produce an absorber overhead gas stream which is passed to a solid absorbent bed. Once saturated, the adsorbed hydrocarbon on the solid adsorbent bed is removed by liquid vacuum pump regeneration, separated from the pump liquid, and returned to the system for use. Hydrocarbon free air is vented from the solid adsorbent bed during the adsorption mode.

Vapor recovery system

A process for the recovery of hydrocarbon vapors from an air-hydrocarbon mixture expelled as a result of storage breathing or loading of a vented hydrocarbon vessel. An inlet air-hydrocarbon mixture is passed to a first absorber in which is fed a vacuum flashed liquid hydrocarbon absorbent to produce a first absorber overhead gas which is passed to a solid absorbent bed. Once saturated, the absorbed hydrocarbon on the solid absorbent is removed by vacuum regeneration, separated from liquid supplied by the liquid ring pump creating the vacuum, and passed to a second absorber vessel where fresh liquid hydrocarbon absorbent is contacted therewith to produce a second absorber overhead gas which is combined with the incoming inlet air-hydrocarbon mixture to pass therewith to the first absorber. Hydrocarbon free air is vented from the solid absorbent bed during the adsorption mode.
