Acid Effluent Treatment Project


Addison Project were approached by our client to complete an EFS (Engineering Feasibility Study) to ascertain the feasibility of increasing the crude brine supply to plant from one feed to three.  This was required to accommodate increased demand but also to achieve different qualities of brine.  It therefore involved a change in design philosophy, hence our involvement in process design.  Once the project was sanctioned Addison were engaged by our client as principal contractor to complete the works through to commissioning of the plant.
