INSTALLATION USED FOR PURIFICATION OF THE PETROLEUM FROM HYDROGEN SULFIDE AND MERCAPTANS (VERSIONS) Russian patent published in 2007 - IPC C10G27/06 B01D19/00 

FIELD: oil-producing industry; petrochemical industry; other industries; equipment for purification of the petroleum from hydrogen sulfide and mercaptans.

SUBSTANCE: the invention may be used for the field purification of the sulfur-bearing oils from hydrogen sulfide and the light methyl mercaptans and ethyl mercaptans. The prepared petroleum through the pipeline (1) is fed into the upper part of the blowing column (3) (Fig.1), and the hydrocarbon gas through the pipeline (2) is fed into the lower part of the blowing column. The partially purified petroleum from the vat of the column (3)is fed into the separator (4), which through the by-pass pipelines is connected to inlet pipelines of the sulfur-bearing oil and the hydrocarbon gas. Further the petroleum from the vat of the separator (4) and the reactant-neutralizing agent from the vat of the tank (5) by means of the mixer (10), in the capacity of which predominantly use the centrifugal pump, is fed into the tubular reactor (11), which is supplied with the quiescent mixer of the reaction mixture. The reaction mixture from the tubular reactor (11) comes in the buffering tank (13). In other version of the installation (Fig.2) the prepared petroleum goes through the pipeline (1) into the nozzle of the liquid-gas ejector (14), which gaseous fitting pipe is connected to the feeding pipeline (2), and the liquid fitting pipe is connected to the sulfur-bearing petroleum feeding pipeline. The gas-petroleum mixture from the liquid-gas ejector (14) comes into the separator (15), which upper part is connected to the suction fitting pipe of the liquid-gas ejector (16) of the pump -ejector installation. The invention allows to reduce the share of the total sulfur, the water, the light mercaptans and the products of the hydrogen sulfide neutralization by the reactant in the separator oil, to reduce the material inputs at operation of the installation.

EFFECT: the invention allows to reduce the share of the total sulfur, the water, the light mercaptans and the products of the hydrogen sulfide neutralization by the reactant in the separator oil, to reduce the material inputs at operation of the installation.
