Generation of Fines in a Delayed Coker (DCU)
This document describes a technical analysis of fines generation in the delayed coking process (Delayed Coking Unit). The focus is on identifying where in the process fine particles are formed, to what extent they are influenced by downstream equipment such as the ECHO system, and which operating and process parameters play a key role.
Based on a case study using real measurement data, it is demonstrated that the majority of fines are already generated within the coke drum process, while downstream equipment contributes only a minor or negligible additional amount.
Transportation of Petroleum Coke–Water Slurry Over Long Distances
This document describes the hydraulic design and feasibility assessment of a 4.5 km long slurry pipeline for transporting a petroleum coke–water mixture within an ECHO plant. The objective of the analysis is to demonstrate that reliable and efficient transport over this distance is technically feasible.
For this purpose, pressure losses, flow velocities, transport capacity, and energy requirements are evaluated in detail.
The results confirm that the required operating conditions are met, sedimentation is avoided, and reliable operation is ensured using the ECHO slurry pump technology.
