Greenhouse gas emissions contribute immensely to global warming. One of the major constituents of greenhouse gas emissions is carbon dioxide (CO2). It is highly essential to reduce its emissions into the atmosphere. One of the ways to reduce its emissions is to capture and store it. Currently, monoethanolamine (MEA) is used to separate out CO2 from the flue gas. This process is expensive and it comes with a signifi Read More

Pour point depressant added in the process of waxy crude oil transmission can effectively improve the fluidity. This is one of the effective ways to achieve crude oil transmission at room temperature. This paper expound the development of pour point depressant, wax crystallization process, classification of pour point depressant, mechanism of the pour point depressant, conditions of limiting the effect of crude oil pour point Read More

This work briefly describes the composition of the lubricating oiland the types of flow improvers, pointing out the advantages of nano-hybrid pour point depressant and some common types of nano-hybrid pour point depressant. The author summarizes the experimental instruments and methods which were commonly used in the study of the mechanism of pour point, pointing out the factors that affect its effect on the lu Read More

Background and Objective: For the alkyl and aryl derivatives of five-membered nitrogen-containing heterocyclic compounds a good correlation has been found between the experimental values of the enthalpy of formation of these compounds in the condensed state and the values calculated using semi-empirical quantum-chemical method PM3. Conclusion: A comparison of the proposed method with that of additive deposits a Read More

Objective: Biodiesel production from microalgae is one of the most suitable and promising sources of clean energy. Various environmental factors affect the microalgae growth. Current study investigates two environmental factors namely temperature and light intensity which affect microalgae growth (by Response surface methodology), and suggests properties of the produced biodiesel through two different methods under opt Read More

Background: Solid suspension in liquids is an important unit operation generally encountered in the process industry. In the present work solid−liquid suspensions are explored in an agitated vessel with different liquids using two radial impellers namely Rushton turbine and straight blade; two axial impellers namely pitched blade turbine and A320. The critical impeller speed (Njs) at which all solid particles get suspen Read More

Background: Dynamic simulation has been finding extensive application in modeling and simulation of various chemical processes. With the availability of high speed computers it has become customary to use Dynamic simulation to analyze various operating scenarios which not only include steady state scenarios but also dynamic situations like startup, planned shutdown and emergency shutdown. In this present work Read More
