Lactose having reproducible pH and a lowered ash level can be produced from lactose rich permeate resulting from the ultrafiltration of whey, by adding a small amount of a chelating agent such as a salt of ethylenediaminetetraacetic acid as, for instance, the disodium salt, the calcium disodium salt, or an alkali metal polyphosphate, as sodium hexametaphosphate to the lactose containing permeate prior to crystallization of the lactose.

A method of producing USP quality lactose which involves

Production of USP quality lactose

A method of producing hydrocarbonaceous liquids and gases from subterranean kerogen-containing oil shale formations comprising (a) penetrating the oil shale deposits with at least two well bores; (b) fracturing the oil shale deposits in a lower vertical portion thereof; (c) igniting the hydrocarbonaceous deposit; (d) introducing through the first well bore a free oxygen-containing gas to the ignited point of the oil shale deposit to effect thermal decomposition of the hydrocarbonaceous material therein and to propagate a combustion zone through the fractured communication area and the second well bore, thereby forming a region of combusted shale between the first well bore and the second well bore; (e) allowing the combustion to continue until a sufficient volume of combusted shale has been formed; (f) then jetting an aqueous liquid into and through the combusted shale zone to remove the mineral residue remaining after combustion; (g) positioning conventional explosives in the oil shale deposit in the vicinity of the washed-out cavity formed in step (g) above; (h) detonating the explosives, thereby causing the oil shale deposit to be fragmented and to collapse into the cavity, thus creating a rubblized zone of relatively high permeability and porosity; (i) then igniting the oil shale and introducing a free oxygen-containing gas at the top of the rubblized zone to combust and retort the rubblized hydrocarbonaceous deposit. Alternatively, a heated liquid may be introduced at a temperature of from around 700.degree. to 1000.degree. F. to effect production of hydrocarbonaceous liquids or gases from the rubblized oil shale.

Oil shale retorting from a high porosity cavern

A method for creating a zone of relatively high permeability within a subterranean carbonaceous deposit which includes gasifying a portion of the carbonaceous deposit to provide a cavity, placing at least one explosive device in the deposit in the vicinity of the cavity so that energy generated upon detonation of the explosive device extends into the cavity, and detonating the explosive device thereby causing a portion of the carbonaceous deposit to be fragmented and to collapse into the cavity.

Method for creating a permeable fragmented zone within a subterranean

A method for locating and identifying sand producing zones in friable, unconsolidated sandstone formations of a subterranean reservoir traversed by a well bore. The method comprises the following steps: A. introducing into said reservoir through said well bore, a radioactive material which is preferentially retained in the porous portions of the formation surrounding said well bore; B. passing a radioactivity detection means through the well bore and recording the measurement of radioactivity of said reservoir; C. returning the reservoir to production; and, D. passing a radioactivity detection means through said well bore and recording the measurement of radioactivity of said formation for a second time and correlating the measurements of radio activity of each measurement with measurement of depth to thus locate sand producing zones in said reservoir.

Method for detecting and locating sand producing zones in friable,

A method for locating water-producing zones and/or water thief zones in a subterranean formation penetrated by a well bore comprising the sequential steps of:
