Use of a New Gas Ejector for a TEG/TREG Natural Gas Dehydration System

نویسندگان

چکیده

Glycol dehydration is the most common and economical water removal method from natural gas streams. However, of low-pressure requires use higher concentration TEG (Triethylene Glycol) or TREG (Tetraethylene Glycol). This article describes how ejector can be used to create a vacuum in glycol reboiler achieve L-TEG/L-TREG (Lean Triethylene Glycol/Lean Tetraethylene Process simulations regeneration units were carried out Chemcad software. Simulations performed for decreasing values working pressure TEG/TREG pressures. Dehydration unit efficiency was tested two flow rates. Ejector performance executed positions process line. The influence reduction on dewpoint has found significant. increase rate greater impact than TEG. Creating with an been shown attractive way improve dehydration. position at end vapor line, downstream condensed separator, allows significant motive consumption.

A Molecular Simulation of Natural Gas Dehydration by 3A Zeolite Nanostructure

The adsorption and separation properties of 3A zeolite are investigated by using Grand Canonical Monte Carlo (GCMC) simulation. To obtain the adsorption isotherms of water, methyl mercaptan, and methane on 3A zeolite, COMPASS Force Filed is used. The adsorption isotherms of the pure components and the ternary mixtures of water, methyl mercaptan, and methane on 3A zeolites are calculated. The Si...

A New Model for Designing Gas Distribution Networks

A new model for the design of the city gas distribution network has been presented. On the basis of mass flow rates and pressure balances a nonlinear system of equation is obtained. A method for solving the latter is outlined which gives accurate results. Also, this method, when compared to the other accessible ones, takes less computer time. Finally in this method the actual length of netw...
