介绍了影响PAM效果的因素,针对PAM现有流程中存在的溶解浓度波动大、溶解时间短、混合不均匀、剪切力影响等问题,采取改变加量频次、通过增加高位槽来增加缓冲时间,改变PAM进入中心筒的方式来降低剪切力,根据负荷及时调整PAM用量等措施改善PAM助沉效果,流程改造后PAM发挥出了最大助沉作用,一次盐水浊度由150 ppm降至70～90ppm,进一步提升了一次澄清能力.
Recent research on deterministic methods for circulating cooling water systems optimization has been well developed.However,the actual operating conditions of the system are mostly variable,so the sys-tem obtained under deterministic conditions may not be
介绍风险分级管控工作中危险源辨识方法与风险评价方法,分析两者之间的关系与区别.风险分级管控的步骤是首先选择一种合理的危险源辨识的方法对分析目标进行全面的危险源辨识,其次选择一种正确的风险评价的方法对辨识出的每一个危险源进行风险评价即取值,最后根据风险值确定风险等级.
A more precise method to evaluate kinetic leakage of anion exchange resin used in condensate polishi
Sulfate mass transfer coefficient (MTC) is a sensitive parameter to evaluate the kinetic leakage of anion exchange resin used in condensate polishing system of thermal and nuclear power plant.However,a suf-ficiently precise determination method has not be
Coupling pinch analysis and rigorous process simulation for hydrogen networks with light hydrocarbon
In refineries,some hydrogen-rich streams contain considerable light hydrocarbons that are important raw materials for the chemical industry.Integrating hydrogen networks with light hydrocarbon recovery can enhance the reuse of both hydrogen and light hydr
Feasibility analysis and process simulation of CO2 dehydration using triethylene glycol for CO2 pipe
The operation of dehydration is very important in the process of gas transportation.This study aims to evaluate the application feasibility of CO2 dehydration using triethylene glycol,which is also called TEG for short.Aspen Plus software was used to simu
Corrosion inhibition of carbon steel in hydrochloric acid by cationic arylthiophenes as new eco-frie
This study describes the adsorption behavior of three arylthiophene derivatives namely:2-(4-amidino-3-fluorophenyl)-5-[4-methoxy phenyl]thiophene dihydrochloride salt (MA-1217),2-(4-amidinophenyl)-5-[4-chlorophenyl]thiophene dihydrochloride salt (MA-1316)
An efficient nano-adsorbent via surfactants/dual surfactants assisted ultrasonic co-precipitation me
To preserve the environment for civilization,we should remove the pollutants like toxic dyes by friendly and cost efficacious method.In this study,the effect of surfactants or mixed surfactants on physicochem-ical,optical and adsorption properties of tern
Introducing a proper hydrogen liquefaction concept for using wasted heat of thermal power plants-cas
A hydrogen liquefaction concept with an innovative configuration and a capacity of 4 kg·s-1 (345.6 t·d-1)is developed.The concept involves an ammonia absorption refrigeration system for the pre-cooling of hydrogen and MR streams from 25 ℃ to-30 ℃.The ammo
