Abstract
A process for partially converting well gas to saleable products on site by disproportionation of the alkanes in the well gas into higher and lower molecular weight alkanes.
Claims42
A process for recovering saleable products from well gas, said process comprising the steps of separating the well gas into an alkane-containing gaseous fraction and a condensate product having a dew point above said gaseous fraction;
- contacting at least a portion of the gaseous fraction in a disproportionation zone with a disproportionation catalyst under conditions selected to convert a significant portion of the alkanes in said gaseous fraction by disproportionation into both higher and lower alkanes;
- and recovering the alkanes from the disproportionation zone as saleable products.
The process of claim 24 wherein the refractory support is selected from the group comprising alumina, zirconia, silica, boria, magnesia, and titania or mixtures thereof.
A process for recovering saleable product from the well gas produced from an oil and gas well which comprises separating the well gas into a crude oil product having a pre-selected vapor pressure and a gaseous fraction;
- contacting a portion of the gaseous fraction in a disproportionation zone with a disproportionation catalyst under conditions selected to convert a significant portion of the gaseous fraction to a syncrude product;
- separately recovering the syncrude product from the remaining light hydrocarbon waste gas;
- and disposing of the light hydrocarbon waste gas.
A process for converting LPG to sales gas and syncrude which comprises contacting the LPG in a disproportionation zone with a disproportionation catalyst under conditions selected to convert a significant portion of the LPG to sales gas product and syncrude product;
- recovering a mixture of syncrude product and sales gas product from the disproportionation zone;
- and separately recovering the sales gas product and syncrude product.
