Embodiment

[0094] Such as Figure 4 As shown, the gas shift system containing light water includes: 500-preheater; 100-shift furnace; 210-first waste pot; 220-second waste pot; 310-first condensate separator; 330-second condensate separator; 340-circulating water cooler 1; 350 third condensate separator; 410-first oil-water separator; 420-second oil-water separator; 700-circulating water cooler 2 ; 600 - stripper.

[0095] Processing steps: Pass 100,000 standard cubic meters per hour dry base crude gas (including light water gas) into the preheater-500, and exchange heat with the shift gas from the shift furnace-100, and the temperature rises to about 250°C , into the shift furnace for water-gas shift reaction. The temperature of the shift gas exiting the shift furnace-100 is lowered from 380°C to 350°C through the preheater 500. The shifted gas enters the first waste pot-210 and the second waste pot-220 successively, and the temperature drops to 160°C after using heat to by-produce 2...

Abstract

The invention discloses a transformation method and a transformation system of a water gas containing light oil. The transformation method comprises the following steps: (1) leading the water gas containing light oil into a transformation furnace in which a catalyst exists and performing an oxidation-reduction reaction on the water gas containing light oil so as to obtain a mixed gas containing carbon dioxide, hydrogen, water vapor and gaseous light oil; (2) performing first cooling treatment on the mixed gas so as to obtain a first gas-liquid mixture of water, the light oil, carbon dioxide, hydrogen, water vapor and the gaseous light oil; (3) performing first gas-liquid separation on the gas-liquid mixture so as to obtain a first liquid mixture containing the water and the gaseous light oil and a first gas containing carbon dioxide and hydrogen. The method used for treating the water gas containing light oil is capable of obviously reducing the consumption of superheated vapor, and is less in energy consumption and low in cost.

Description

technical field [0001] The invention relates to a water-gas shift process, in particular to a light oil-containing water-gas shift method and a light oil-containing water-gas shift system. Background technique [0002] Carbon monoxide shift is an important conversion process in the production processes of methane synthesis, ammonia synthesis, oxo synthesis and hydrogen production. In the carbon monoxide conversion process, the hydrogen-to-carbon ratio is adjusted by converting carbon monoxide into hydrogen, and then synthetic methane, ammonia, methanol, hydrogen and other chemical products are produced through different types of reaction processes. [0003] However, the existing water gas treatment methods still need to be further improved. Contents of the invention [0004] The present invention aims to solve one of the above-mentioned technical problems at least to a certain extent. Therefore, an object of the present invention is to propose a water-gas shift method an...
