An improved process for extracting hydrocarbons from a diatomite ore which comprises the combination of the steps of: a) Reducing the particle size of the ore to form a processed ore; b) Grinding the processed ore in an enclosed pin mixer to form pelletized ore; c) Feeding the pellets into each section of a ROTOCEL.RTM. extractor unit containing 5-8 sections or baskets to form columns of pelletized ore; d) Distributing a solvent from the top of each column of the ROTOCEL.RTM. extractor and allowing the solvent to permeate the pelletized ore column to form a hydrocarbon-rich solvent stream while leaving behind spent ore mixture; e) Separating extracting solvent from the hydrocarbon solvent stream to form a hydrocarbon product stream and an extracting solvent stream; f) Removing the spent ore mixture from the extracting zone; g) Recycling the extracting solvent; and h) Recovering the hydrocarbon product.

Process for extracting hydrocarbons from diatomite

A synthetic gas generator receiving oxygen and natural gas through separate pipes provides synthetic gas. The methane content of the synthetic gas is sensed and a corresponding methane signal is provided. Carbon monoxide and fuel hydrogen are removed from the synthetic gas and provided in different pipes. The pressure of the carbon monoxide is sensed and a corresponding pressure signal is provided. Control apparatus controls the oxygen and natural gas entering the synthetic gas generator in accordance with the methane signal and the pressure signal.

Control system and method for a synthesis gas process

Carbon content of vent and purge gases from hydrotreating is included as charge to synthesis gas generation with resulting efficiencies including decreased need for steam moderation and increased conversion of charge to desired product.

Integrated H-oil process including recovery and treatment of vent and

Coal or similar solid carbonaceous fuels are liquefied by catalytic hydrogenation of coal-liquid hydrocarbon oil slurries with a hydrogen-rich gas. Both the liquid hydrocarbon slurrying oil and the hydrogen-rich gas are derived in the process. Noxious hydrogen-containing purge and vent gases and optionally high ash-containing bottoms from a vacuum fractionator are used as feed to a partial oxidation gas generator to produce synthesis gas from which the hydrogen-rich gas is derived.
