Troubleshooting FCC operations to improve performance
Dave Ferguson, Tracerco
Investigations of Fluid Catalytic Cracking Unit (FCCU) operations using radioisotope technology tools provide a better understanding of the equipment. This information aids operations staff to make operational corrections or mechanical repairs to reduce losses and improve performance.
How to develop the optimal cleaning strategy for crude pre-heat trains?
Shelby Hegy, Sunil Patil, AspenTech
This paper outlines how process simulation software and heat exchanger design & rating software can be used to monitor fouling in crude pre-heat train and industry examples of success using this approach.
Domains of flammability and thermal ignitability for organic dust – polyethylene
Manju Mittal, CSIR-CBRI
This paper reports experimental data for particle size dependence of minimum explosible concentration (MEC) determined using CSIRCBRI 20-L Sphere at ambient conditions and minimum ignition temperature (MIT) of dust-air cloud measured in Godbert-Greenwald furnace for an organic dust- polyethylene.
An engineer’s guide to the design of multi-purpose chemical plants
D V Saraiya, Mott MacDonald
Products become obsolete or get phased out as new options enter the market. Therefore, it is necessary that the investments made in production facilities for chemical plants have the flexibility to change from one product to another. The concept of a multipurpose plant (MPP) has evolved from this need. This article covers major critical aspects of MPP design.
