Characteristics and Economic Analysis of Natural Gas Utilization in Northeast Petrochemical Enterprises
摘要
Abstract
Petrochemical enterprises in Northeast China mainly produced fuel hydrogen from natural gas;the gas units included crude distillation unit, reforming unit, hydro-treating unit, catalyst unit, ethylene unit, delayed coking unit, molecular sieve dewaxing unit, benzene and styrene unit.About (25~30)×104 m3 gas was consumed for one petrochemical enterprise processing ten million tons of crude oil per annum.The main factors that affected the total amount of natural gas consumption included alternative energy, seasonal variation, maintenance, market, emergencies, etc.The calculation of natural gas price bearing capacity with the surrogate worth trade off method showed the price of alternative energy such as naphtha and liquefied gas directly affected the economy of natural gas utilization.Clarifying the use regulation and economic characteristics of nature gas in petrochemical enterprises was conducive to optimizing the plan design of gas utilization, controlling cost and coordinating with the upstream gas suppliers.关键词
