Comparison of prices and calorific values of LNG, LPG, and diesel 1. LNG: It is in liquid state at -146°C and at normal pressure. Standard volume: 1,240 cubic meters per ton (at 20°C). Calorific value: 11,291 kcal/m³ (C1: 85%, C2: 14%, C3: 1%). Calorific value on a weight basis: 14 million kcal/ton. 2. LPG: It is in a liquid state at 30°C and 1.3 MPa. Standard volume: 501 cubic meters per ton (at 20°C). Calorific value: 250,000 kcal/m³; calorific value on a weight basis: 12.53 million kcal/ton. 3. Diesel: Calorific value: 10,000 kcal/kg, 10 million kcal/ton. 4. Comparison: 1) LNG: Price is 3,500 yuan per ton; 14 million kcal per ton ÷ 3,500 yuan per ton = 0.400 million kcal per yuan. 2) LPG: Price is 6,000 yuan per ton; 12.53 million kcal per ton ÷ 6,000 yuan per ton = 0.208 million kcal per yuan. 3) Diesel: Price is 4,900 yuan per ton. 10 million kcal per ton ÷ 4,900 yuan per ton = 0.204 million kcal per yuan.
