Most customers dread having to conduct a full cleanout of a TEG dehydrator. The cleanout sometimes implies shutdowns or drop in capacity. One of the ways CROFT designed the Passive Dehydration System (PDS) is to be utilized as a quick, easy, and a temporary way to bypass a TEG and continue to dehydrate the gas while your TEG is shut down and getting serviced/cleaned out.

The CIS 30 MM model. This system was designed to have different static mixers to create enough turbulence and increase contact time without creating too much of a pressure differential. It has a modified two-phase separator to act as a bubble tower for efficient use of the chemical while providing proper separation.

Absorption vs. Adsorption Dehydrating natural gas, or the removal of water vapor from natural gas can be done by either adsorption or absorption. Croft’s Passive Dehydration System uses adsorption, where water vapor is collected and condensed on the surface with the use of a solid desiccant. Solid desiccants have a high adsorption capacity, a low resistance to gas […]

CROFT Passive Dehydration Systems natural gas dehydration unit that utilizes a specially formulated solid desiccant called enviroDRI to adsorb water from the gas stream. Below are our clients’ most commonly asked questions about enviroDRI. What is enviroDRI? enviroDRI is a deliquescent desiccant pellet about the size of an almond designed to adsorb water from hydrocarbon […]

Oil storage tanks serve as a staging area to collect crude oil in several stages of production. These tanks are used in production fields and hold the oil until it is delivered to tankers or into a pipeline. Storage tanks are also used as a holding area for crude oil before the refining process and they also hold refined products after it is processed.

An oil and gas separator is used for removing and collecting liquids from natural gas. A properly designed separator will also provide the release of entrained gases from the accumulated hydrocarbon liquids. These separators can go by many names or different purposes like liquid separators, oil separators, water and oil separators, etc., but the most […]

A bullet tank is a storage container that houses natural gas liquids (NGLs). The tanks come in many different sizes and include accessories that best suit your operation. Bullet tanks range from 6,000 to 30,000 gallons, with an 18,000-gallon tank being the most common size. Tanks should be no more than 70-80% full in order for […]

This timelapse video shows the two day-long insulation process in just 30 seconds. Joule Thomson Systems (JT) are important systems in your surface processing operations, and if the piping and heat exchangers are poorly sealed or insulated they are likely contributing to lower efficiency gains and consistent cold separator temperatures. The Joule Thomson System simultaneously reduces the […]

Croft has just installed a Fuel-gas Conditioning System (FCS) for a new client in the Eagleford and is already showing excellent results. The unit, our FCS-500, takes the high pressure/high temperature gas from the discharge of the compressor and cools, separates, dehydrates, reduces the BTU, and reduces the pressure to the required fuel system PSI. The reduction […]
