Recently, Zhenghe Group’s oil and gas recovery project has smoothly come online, signifying that the company has completed the Shandong government’s requirements on oil and gas renovation ahead of schedule. It also means the company has realized the dual goal of environmental protection and benefits enhancement. 

The Shandong provincial government and Dongying municipal government signed a responsibility agreement to treat air pollution (Phase I) from 2013-2015. The agreement states clearly that by the end of 2014, work on oil and gas treatment for all gas stations, oil depots and oil tankers will be finished.

The project adopts the "condensing, membrane and adsorption" three-step process. It collects volatile oil and gas and sends them to recovery equipment, which begins working when the air compressor starts automatically. The oil and gas are then condensed into liquids and go into the membrane separation unit. The oil and gas molecules will be separated from air under differential pressure. Then, the low-density gas will be discharged after going through an adsorption unit for purification. The organic gas will be transported by vacuum pump to the compressor entrance for recovery. When the recycled liquids reach a certain pressure, they will automatically be sent back to the product tank zone. 

At present, the project is running steadily. The test result by Qingdao Pony Test showed that the average concentration of entering oil and gas stood at 485 grams per cubic meter. The outgoing oil and gas concentration was at 9.49 grams per cubic meter, fully meeting the oil depots atmospheric pollutant emission standard (GB20950-2007). A preliminary calculation showed that the project can recycle 551.3 liters of oil per day, with a density of 0.65 kg per cubic meter. If it goes by the market price of 7,000 yuan per ton, it can save 916,000 yuan ($149,534) for the company in oil and gas recovery.
