High use periods of natural gas, espe cially during the winter months, place heavy peak load requirements upon suppliers. To solve this problem with out expanding their facilities, many natural gas suppliers are now utiliz ing peak shaving operations. Such an operation is the Lowell Gas Co.'s plant in Tewksbury, Massachusetts. Designed and built by Envirogenics Co., a division of Aerojet-General, this plant takes advantage of low de mand periods to compress and refrig erate natural gas into a liquid which can be stored in a smaller volume and then pumped and vaporized during high use periods to "shave" the "peak" load requirements. Davison Chemical worked with Envirogenics Co. to design a series adsorption system for the removal of water and CO2 from the gas. The high adsorptive capacity of Grade 03 silica gel removes large quan tities of dissolved water from the gas to meet the low dew point require ments necessary for liquefaction. After the gas enters the liquid phase, Davison 13X molecular sieves are used to remove the CO2 from the LNG prior to storage. Through this dual-bed system of Davison high capacity Grade 03 silica gel and 13X molecular sieves for moisture and CO2 removal, Lowell Gas utilizes the best properties of each adsorbent in an efficient removal of contaminants from natural gas.
