A METHOD OF INCREASING THE EFFICIENCY OF A PIPELINE WHICH COMPRISES ESTABLISHING A GAS INLET TO AND A GAS OUTLET FROM THE PIPELINE AT A SUFFICIENT DISTANCE APART THAT WHEN GAS IS ADMITTED TO THE INLET, AT LEAST SEVERAL MINUTES ARE REQUIRED FOR GAS IN THE PIPELINE TO ACHIEVE STEADY STATE FLOW CONDITIONS WITH THE VELOCITY OF GAS IN THE PIPE ADJACENT TO THE INLET SUBSTANTIALLY LOWER THAN THAT OF GAS IN THE PIPE ADJACENT TO THE OUTLET AT SUCH CONDITIONS, PERIODICALLY ADMITTING GAS THROUGH SAID INLET AT RATES FLOW AND FOR INDIVIDUAL TIME INTERVALS OF SUCH LENGTH THAT THE GAS PRESSURE IN THE LINE ADJACENT TO THE INLET CONTINUOUSLY INCREASES TO A SUBSTANTIALLY HIGHER VALUE THAN THAT AT THE OUTLET AT THE END OF EACH INTERVAL; SPACING SAID INTERVALS APART SUFFICIENTLY THAT THE GAS PRESSURE IN THE PIPE ADJACENT TO THE INLET DECREASES TO A VALUE APPROACHING THAT OF GAS IN THE PIPE ADJACENT TO THE OUTLET BETWEEN SAID INTERVALS, AND SUSPENDING SAND IN SAID GAS AT THE INLET DURING AT LEAST THE INITIAL PORTION OF SAID INTERVALS WHEREBY THE PIPELINE ADJACENT THE INLET IS SUBJACTED TO THE ACTION OF SAID SAND WHILE TRAVELING AT RELATIVELY HIGH VELOCITIES DURING SAID INTERVAL PORTION.
