 The removal of phenol pollutant from water was studied using continuous adsorption process onto MS type 13X. This adsorbent was treated with urea and thiourea to enhance its adsorption ability towards phenol.The preparation step was made by mixing of saturated solution of urea or thiourea, with powder molecular sieve 13X and adding sodium silicat as binder to give homogenous mixture in approximate weight percent, 20 wt% urea or thiourea, 30 wt% binder, 50 wt% MS13X.

Prediction of the accurate values of molar volume of compressed liquids is very important in process design calculation and other industrial applications. Experimental measurements of molar volume V for compressed fluids are  very expensive , so in order to obtain accurate V values, attention has been turned to calculate it from equation of state   Alto and Kiskinen[1] equation for pure non polar component,  using correlations to Tait equation for polar component, and modification of Rackett equation are used for mixtures.

     The importance of corrosion is techno — economic ,i.e.reducing material losses resulting from corrosion of piping,tanks, metal components of machines, ships, bridges, marine structures, etc.
