UNIT FOR CONVERSION OF SYNTHESIS GAS INTO LIQUID HYDROCARBONS OF NATURAL GAS PROCESSING PLANT Russian patent published in 2017 - IPC C07C1/00 B01J19/00 

FIELD: oil and gas industry.

SUBSTANCE: main process unit in the unit for conversion of synthesis gas into liquid hydrocarbons is a catalytic reactor which consists of a vertical cylindrical body with axial inlet and outlet branches. Inside the body there is a catalyst, and a casing with upper and lower bases is coaxially mounted outside the body. The steam drum with a cover and bottom is placed above the upper base. The outlet pipeline is connected to the upper base and the cover, and the supply pipeline is connected to the lower base and the bottom, respectively. A heat exchanger-coil is installed in the inner cavity of the steam drum, which one end is hydraulically connected to the inlet branch of the body, and the other end is connected to the recuperative heat exchanger. The mixing unit is hydraulically connected to a pressure pipe union of the compressor with a pressure reducing valve and with a recuperative heat exchanger. The recuperative heat exchanger, a gas-liquid separator and a suction pipe union of the compressor are connected in series to the outlet branch pipe of the body. Hydraulic connection between the pump pressure branch pipe and the inner cavity of steam drum is provided by means of pressure pipeline which is connected to the cover together with shutoff-and-regulating valve and a manometer. A return valve is installed in the pressure pipe. The pump suction branch pipe is hydraulically connected to accumulating tank, and the pressure branch pipe is connected to pressure pipeline. The pump is started and stopped automatically by using a control unit with a fluid level sensor which is placed in the accumulating tank. The shutoff-and-regulating valve is connected to heat exchanger-cooler by means of a steam release line, and the latter is connected to accumulating tank. There are thermometers mounted on the casing, input and output tap which ensure temperature control of respective liquid heat carrier, incoming reaction gas and the outgoing reaction products.

EFFECT: reduced consumption of energy for production of liquid hydrocarbons and increased efficiency of reactor.
