Title: Process for removal of mercury from a liquid hydrocarbon
Inventor: FURUTA AKIO
IPC: C10G29/10
Filed: 1989-05-12
Granted: 1993-10-19
Abstract: ABSTRACT OF THE DISCLOSURE           A liquid hydrocarbon such as a natural gas liquid generally contains a small amount of mercury in a state of elemental mercury, ionized mercury, ionizable mercury compounds, which are requested to be removed thoroughly. Further, organic mercury compounds are contained in some natural gas liquid and other liquid hydrocarbons depending on their district of production, and its removal is also necessary. Already known adsorbents can adsorb elemental mercury and organic mercury compounds in a liquid hydrocarbon, but they hardly adsorb ionizable mercury compounds and ionized mercury derived from the ionizable mercury compounds. According to the present invention which comprises contacting the liquid hydrocarbon with a sulfur compound represented by a general formula MM'Sx, wherein M is selected from a group consisting of alkali metal and ammonium radical, M' is selected from a group consisting of alkali metal, ammonium radical and hydrogen and x is a number of at least 1, the sulfur compound and mercury in the liquid hydrocarbon reacts to form mercury sulfide which is insoluble in the liquid hydrocarbon to be separated therefrom. If the liquid hydrocarbon contains organic mercury compounds together with elemental mercury ionized mercury and ionizable mercury compounds, the above-mentioned process is to be combined with a process of contacting the liquid hydrocarbon with an adsorbent comprising heavy metal sulfide to adsorb the organic mercury compounds together with the mercury sulfide which is formed in the above-mentioned process.

Title: Mass transfer mixing system especially for gas dispersion in liquids, or liquid suspensions

Abstract: MASS TRANSFER MIXING SYSTEM ESPECIALLY FOR GAS DISPERSION IN LIQUIDS OR LIQUID SUSPENSIONS                        Abstract A mixing system for dispersing gas or other fluids in liquid which may have a solid suspension so as to improve mass transfer to the liquid or its solids suspension while maintaining a flow pattern which is substantially axial (up and down) in the tank containing the liquid thereby also facilitating mixing (blending) utilizes an (unshrouded) axial flow impeller which provides the desired single stage axial flow downwardly to the bottom of the tank and upwardly along the sidewalls of the tank with radial flow confined principally to the bottom region of the tank.  A sparge system which releases the gas or other fluid in the region at the bottom of tile tank where the flow is predominantly radial allows attainment of gas rates with complete dispersion of gas throughout the tank, which rates are much higher (about four times as great) as when conventional sparge systems are used with axial flow impellers.  The gas rate is maximum when the impeller has a plurality of blades which are located at an elevation of fifteen to twenty-five percent of the impeller diameter from the bottom of the tank and the outlet ports of the sparge which delivers the gas are located at a radius greater than the radius of the impeller and at about the same elevation from the bottom of the tank as the elevation of the lower edges of the impeller's blades.  The condition known as flooding where the escaping gas, rather than the impeller, controls the flow pattern in the tank (the escaping gas then not flowing with the liquid as it is pumped by the impeller but rather rising due to its own energy and geysering out of the liquid) does not occur, even though an axial flow pattern is maintained by an impeller of the axial flow type which pumps by virtue of the pressure differential across the impeller blades, rather than by direct impact with the liquid as in a radial flow impeller.
