Abstract: An apparatus and method for controlling a well plunger system for the production of natural gas is described. The well plunger system includes a plunger tube positioned within a casing of a gas well, a tubing line connected to the plunger tube, a plunger moveable within the plunger tube, a plunger sensor for detecting the presence of the plunger, a valve connected to the tubing line and to the general gas distribution system including a sales line and a gas flow meter, a pressure sensor connected to the sales line, a motor for operating the valve, and a pressure sensor connected to the casing. The controller calculates the duration of an open interval when the valve is opened and a closed interval when the valve is closed based on a calculated average plunger velocity of the plunger after the valve is opened. The controller compensates for changes in sales line pressure by adjusting the calculated average plunger velocity by an amount equivalent to the changes in sales line pressure.

Abstract: A thermal process co-recycles tires with oils to produce gases, liquids and solids. The latter consisting of glass and steel fibers and a carbonous residue which are separately segregated and collected. By using selected additives gas formation and hydrogen sulfide contents are reduced, light product oil yields and quality are maximized and the level of chlorinated substances in the oils are reduced to trace amounts. The carbonous residue makes an excellent modifier for improving performance properties of bituminous binders and bituminous mixtures and for providing added benefits to properties of Portland concrete.
