Laboratory study to improve the expansive soil by adding chemical Stabilizers

The purpose of this research is to study the improvement of soil properties by the addition of lime in certain percentages. The soil used in this study was obtained from the Baseet region, which is located by the Syrian coast. We have studied the effect of lime on the consistency, the swell characteristics and the shear strength of soil. The results of this study have shown a remarkable reduction of both liquid and shrinkage limits, and the plasticity index with the increase of lime percentage. As for plasticity limit, it increases in the beginning then decreases slightly with the rising of lime percentage. For the volumetric variation, the susceptibility of swelling and the shrinkage of improved soil with lime decrease, and the free swelling and the swelling pressure become almost negligible with 4% of lime. Based on the shear strength results, we can indicate a notable increase in the friction angle and cohesion of soil with increasing of lime percentage up to 8% of lime. After that, these two factors decrease.

Study of the natural gas condensate stabilization process by non-refluxed fractionation column using the computer

This research aims to study the process of natural gas condensate stabilization by fractionation tower without reflux, and study the effect of operating factors affecting the process such as the operating pressure and temperature feed.
