Environmental Tests Comparing Kress Indirect Dry Cooling with Conventional Coke Oven Pushing and Quenching

摘要

The paper describes the Kress Indirect Dry Cooling (KIDC) process and gives results of an evaluation through baseline and demonstration emission testing. The KIDC process offers a technology that has the potential to reduce emissions from coke pushing and quenching at existing coke oven batteries. In a 2-month demonstration on a 4-m battery, all 321 Kress pushes were successful. A box slightly larger than the coke charge was positioned flush against the coke oven and received the push. Then the box was sealed and transferred to the quenching station where the coke was indirectly quenched by running cooling water on the outside of the box. In the conventional process, the coke is exposed to air and water, often resulting in extensive particulate and volatile organic compound (VOC) emissions.
