Ensuring Accuracy
BLOWDOWN Technology Background
Developed by Dr. Graham Saville and Prof. Stephen Richardson of Imperial College
• BLOWDOWN Technology was not offered as software product, only a consulting service • Industry trusted and gold standard technology for depressurization, validated against actual plant data from nearly 30 years of research work – Considered state-of-the-art tool for blowdown studies – Predicted temperatures accurate within +/- 3 oC

Question & Answer Session © 2015 Aspen Technology, Inc. All rights reserved
Blowdown and Vessel Depressurization • What is a blowdown system? – System that reduces the internal pressure of a process segment – Regulated by API 521, NORSOK, ISO 4126, etc
• Why is it done? – Protect plant assets against the effects of high temperatures – De-inventory hazardous material during plant emergency
• Why simulate?
•
– Multiple complex fundamental phenomena makes analysis difficult – Risk assessment
35

Can the vessel relieve within safety standards? Where is the temperature too low? What are the relief loads leaving the vessel into the flare?
Overview of the Workflow Gather Data
Design the orifice
Isometrics Equipment datasheets Company/ Client guidelines for analysis
Find the smallest orifice diameter that satisfies the “acceptance criteria”
Verify system MDMTs Ensure that, for the given design, the selected system metallurgies are appropriate for all operating modes
