Designing a distillation column with high liquid loading at high pressure system generally will encounter challenges due to
- High Liquid flowrate
- Low density difference
- Low Surface tension
- Low Separation efficiency
Downcomer design will be critical in High pressure - high liquid loading system. SULZER has presented special design considerations for above mentioned system in the AICHE annual meeting.
Except for a few odd services, high liquid rate applications are typically the domain of either trays or random packings. Aside from the distributors, random packing designs are rather straightforward with the designer choosing the proper size to accommodate the fluid flow rates and achieve the desired efficiency. Trays, on the other hand, have a large variety of adjustable parameters and can be especially complex, especially when designed for high liquid rate applications...
If you designing or operating a high pressure high liquid loading system, this paper may provides you some ideas.

Through some of the visitor, i found this site...This site have some interesting articles particular for Refinery engineer...
Triton Analytics Coporation (TAC) was founded in 1991 by Dan C. Villalanti, Ph.D. to serve the growing needs of the petroleum industry. TAC now services over 150 oil, gas and petroleum companies worldwide seeking high precision, reliable analytical results. Since the inception of the company, TAC has set industry standards for gas analysis, exact structure determination of hydrocarbons (NOISE), and High Temperature Simulated Distillation (HTSD). Sample matrices include crudes and feedstocks, distillates, motor oils and heavy residuals up to vacuum tower bottoms. Since that time, TAC capabilities have continued to expand to also include titrimetry with the highest precision available, detailed hydrocarbon analysis (DHA), and Vapor Pressure determination of petroleum mixtures.

Above efforts will reduce CO2 release into atmosphere. However, recycling CO2 will increase quantity of CO2 in oil and result serious corrosion problem. Hence it needs to be removed from the flashed gas (from unstabilised oil). CO2 removal technology using amine absorption has been used for many years. Recently i found a website (OGT) where the founders, Ralph Weiland and Jack Dingman are those experts in this technology.
Optimized Gas Treating, Inc. (OGT) was established in 1992 by Ralph Weiland and Jack Dingman for the single purpose of providing a commercial version of a Windows-based software package for simulating acid gas removal with aqueous alkanolamines that uses a fundamental mass and heat transfer rate approach to column modeling. ProTreat™ is the culmination of more than 30 years of research in gas treating supported by government and industry in both academic and commercial environments. ProTreat is our sole product. Consequently, it receives our undivided attention in maintaining and enhancing its capabilities so that it remains the premier software package for gas treating with amines. OGT’s principals are recognized world experts in most aspects of gas treating — they offer a total of nearly 60 years of relevant experience.
