LTX Unit as a Condensate Stabilizer

It should be clear from the description of LTX units that the lower pressure separator in an LTX unit is a simple form of cold-feed condensate stabilizer. In the cold, upper portion of the separator some of the intermediate hydrocarbon … Continue reading

Condensate Stabilizer as Gas Processing Plant

A gas-processing plant, is designed to recover ethane, propane, butane, and other natural gas liquids from the gas stream. A condensate stabilizer also recovers some portion of these liquids. The colder the temperature of the gas leaving the overhead condenser … Continue reading

Stripping Service

For stripping service, as in a glycol or amine contactor , bubble cap trays are the most common. In recent years, there has been a growing movement toward crimped sheet structured packing. Improved vapor and liquid distributor design in conjunction … Continue reading

Distillation Service

For distillation services, as in condensate stabilization, tray design is well understood, and many engineers are more comfortable with trays than with packing. In the past, bubble cap trays were the standard. However, they are not commonly used in this … Continue reading

Structured Packing

A bed of structured packing consists of a bed support upon which elements of structured packing are placed. Beds of structured packing typically have lower pressure drops than beds of random packing of comparable mass transfer efficiency. Structured packing elements … Continue reading

Random Packing

A bed of random packing typically consists of a bed support (typically a gas injection support plate) upon which pieces of packing material are randomly arranged (they are usually poured or dumped onto this support plate). Bed limiters, or hold-downs, … Continue reading

Tray Efficiency and Tower Height

In condensate stabilizers, trays generally have 70% equilibrium stage efficiency. That is, 1.4 actual trays are required to provide one theoretical stage. The spacing between trays is a function of the spray height and the downcomer backup (the height of … Continue reading

Bubble Cap Trays vs. Valve Trays

At low vapor rates, valve trays will weep. Bubble cap trays cannot weep (unless they are damaged). For this reason, it is generally assumed that bubble cap trays have nearly an infinite turndown ratio. This is true in absorption processes … Continue reading

Bubble Cap Trays

In bubble cap trays, vapor flowing up through the tower contacts the liquid by passing through bubble caps (Figure 6-7a). Each bubble cap assembly consists of a riser and a cap. The vapor rising through the column passes up through … Continue reading

Valve Trays

Valve trays are essentially modified sieve trays. Like sieve trays, holes are punched in the tray floor. However, these holes are much larger than those in sieve trays. Each of these holes is fitted with a device called a “valve.” … Continue reading
