为大庆油田研制的SH10油罐烃蒸气回收装置,填补了我国烃蒸气回收设备的空白。该装置的主要用途,是回收45℃左右5000m3大罐中石油挥发的气体——烃蒸气,是生产乙烯的贵重的化工原料。按每立方米0.15元计算,每年可回收2.464×105m3（7488m3/d）,计36.96万元。除去运行费用（人工、耗电、耗热、维修）折旧费用10.61万元外,净收入26.35万元。如投资（设备、安装费用）按28万元计算,则1.06年全部收回,对国家能源的回收将具有重大意义。
Developed for the Daqing Oilfield SH10 tank hydrocarbon vapor recovery unit to fill China’s hydrocarbon vapor recovery equipment blank. The main purpose of this device is to recover the vapor of hydrocarbon volatilized in the large tank of 5000m3 at about 45 ℃, which is a valuable chemical raw material for the production of ethylene. Calculated at 0.15 yuan per cubic meter, 2.464 × 105m3 (7488m3 / d) can be recovered annually with a total amount of 369,600 yuan. Remove the operating costs (labor, electricity, heat, maintenance) depreciation costs 106,100 yuan, the net income of 26.35 million yuan. If the investment (equipment, installation costs) calculated at 280,000 yuan, then the total recovery of 1.06, the recovery of national energy will be of great significance.
