1988年2月美国石油炼制者协会(NPRA)问答会介绍了有关节能经验.现简述如下: 1.控制用能的操作方法联合太平洋资源公司(Vnion Pacific Resources Co.)认为有三条主要经验:1)监控工艺加热炉和锅炉每班操作的过剩O_2量和CO量.典型的过剩氧量目标为小于4%.2)烧火式锅炉发汽正好供蒸汽透平驱动,透平排出的低压蒸汽供蒸馏塔作重沸器使用.3)采用计算机控制,使之最大量回收产品和最少量使用能量.其它途径包括:每月、每季调查蒸汽疏水器;控制燃料气生产;尽量不作二次泵
The February NPRA Q & A Session presented the energy saving experience and is summarized as follows: 1. Operational Methods for Controlling Energy With Vnion Pacific Resources Co., there are three main experiences : 1) Monitor the excess O_2 and CO in each shift of process furnaces and boilers, with a typical excess oxygen target of less than 4% .2) Boil-off of a boil-fired boiler is for steam turbine-driven low pressure Steam distillation column for reboiler use .3) the use of computer control to maximize the recovery of products and the use of the least amount of energy.Other ways include: monthly, quarterly survey steam traps; control of fuel gas production; try not to make two Sub-pump
