The design or specified minimum temperature approach of a heat exchanger has a significant effect on the total heat transfer area required. As a result, the specified temperature approach (TA) should be carefully considered in the heat exchanger specification process as this is one of the primary factors in heat exchanger capital cost. Depending uponContinue Reading

This Tip of the Month shows how a Short Cut Method (SCM), after one Performance Test Run (PTR), may be used to estimate the life of a Type 4A molecular sieve dehydrating a water-saturated feed of natural gas. The May 2015 Tip of the Month [1] discussed the benefits of standby time. In that Tip (whichContinue Reading

Problems in meeting sales-gas dew point specifications are not unusual in plants. A facility engineer often suspects separator carryover when troubleshooting such a plant. Proper sizing of equipment for gas-liquid separation is essential to almost all processes. Many facility operating problems are related to improperly designed or under-sized gas-liquid separators. The following list presents items that canContinue Reading

Continuing the September 2018 tip of the month (TOTM) [1], the phase behavior of ethane and water binary system was studied. Like propane–water system [2], the ethane–water system is complicated for the following two reasons: 1. Very low mutual solubility in liquid phases. 2. At lower temperatures, ice or hydrates is formed. In this tip, we will evaluate theContinue Reading

In facilities operations, the understanding of where the process is on a phase diagram can often help the engineer and operator to avoid extremely embarrassing design and operating mistakes. A phase diagram is a function of only mixture compositions and components. Though it is expensive and time consuming, a phase envelope can be determined experimentally by measuringContinue Reading

►Watch Mick Crabtree’s Harnessing Coriolis Webinar It was not until Gaspard-Gustav de Coriolis published a paper in 1835 that the terms Coriolis Effect andCoriolis Force were actually coined [1]. Nonetheless, the effect had been described by the Italian scientist Giovanni Riccioli in 1651 who postulated that if, in the astronomical model of the solar system, the Earth rotated aroundContinue Reading
