Title: Ju-Nam Chew: Innovator in Hydrocarbon Recovery and Coal Separation
Introduction
Ju-Nam Chew is a notable inventor based in Dallas, TX (US), recognized for his contributions to the field of hydrocarbon recovery and coal separation. With a total of 5 patents to his name, Chew has made significant advancements in methods that enhance the efficiency of resource extraction.
Latest Patents
One of Chew's latest patents is a heavy oil recovery process using intermittent steamflooding. This innovative method focuses on recovering viscous hydrocarbonaceous fluids from subterranean formations that contain vertically extensive, narrow, high permeability conduits. The process involves injecting steam into an injection well until the water-oil ratio at the production well becomes excessive. The production well is then shut in to allow the formation to pressurize, after which the production well is opened for production by pressure depletion. This cycle continues until oil recovery is no longer economical.
Another significant patent by Chew is a method for separating mixtures of bituminous coal and lower rank coal. This process involves contacting the coal mixture with an effective amount of an aqueous chemical comminuting solution for a sufficient time to selectively comminute a substantial portion of one of the ranks of coal. The comminuted and noncomminuted coal is then separated from the solution, allowing for efficient extraction of different coal ranks.
