Various options for reducing the TMT of a vacuum heater, such as changing the transfer line size and adding extra surface area in the radiation and convection sections, are examined here. The best option generally depends on the limitations under which the heater operates with regard to the process requirements and the downstream equipment limitations and flexibility.
Several improvements are on the horizon, which will add powerful optimization capabilities into the process modeler’s simulation work space in areas like heat integration, column optimization and economics.
With the fluctuation of natural gas pricing, it is important to evaluate technically feasible solutions and choose the most economical alternative. Ultimately, this leads to a simpler and more cost-effective solution.
In the presented case study, an innovative design for an integrated CGC-DeC3 system introduces part of the heavier condensate from the early compression stages directly into the high-pressure (HP) depropanizer.
With the prospect of abundant low-cost ethane, several producers have announced intentions to build new ethylene capacity.

Engineers and designers are highly skilled individuals. Forcing them to enter design changes using tables, forms and spreadsheets is unproductive and uneconomical, and it increases the likelihood of human error—this is the way that most instrumentation software systems currently work. For too long, software vendors have denied engineers and designers the simple practicality of a graphical visual engineering interface with “drag and drop” capability and inbuilt intelligence, ensuring changes are automatically replicated into all the associated data and databases.

Will previously-planned downstream investments be cut back in 2015 due to lower global oil prices?
Depends how long current prices last
