Mud gas separator is a kick off equipment used to process large quantity entrained gas. Among the gas, there is H2S, natural gas, SO2, methane, and so on. What issues impact mud gas separator degassing capacity?

Mud gas separator degassing capacity affecting issues

There are many issues may affect the degassing capacity. Such as degasser vessel size, the inlet and out put pipe size, the vent line size, the mud flow rate, degasser design or configuration, and so on. Furthermore, the gas ppm value and pressure will affect degassing efficiency, too

For example, APMGS1000 mud gas separator, the maximum degassing volume is about 6125m³/h. The mud flow rate is up to 300m³/h. So the permitted gas content in drilling fluid entering poor boy should be not higher than 20.4 under the normal pressure

H2S elimination ability

The H2S elimination ability is the efficiency of the degasser. Usually we can't get a confirmed value. As the gas bubbles and the drilling condition at different site will be different.

The mud gas separator can get rid of entrained gas bubble sized over 3mm. The smaller ones will be hard to break and move out. However, we have vacuum degasser can handle about 95% gas out of drilling mud

So, if we wish get the H2S value is a certain value, we have to install the concentration meter and do the subsequent process

Mud gas separators types

The mud gas separator degassing capacity is impacted by degasser design or configuration. Such as the internal blades design, or if there is umbrella pattern nozzle instead of blades.

Mud leg or mud seal will affect final result, too. It will help to let gas flow upward till to the vent port and won't come back to the degassed mud.

There are degasser with 800mm diameter vessel, 1000mm, 1200mm. The pressure can be normal pressure, or high pressure. Such as 1.2Mpa, 6.4Mpa, 10Mpa, and so on. Different pressure requirements request different flange grade and the different thickness of material.

To resist high concentration H2S, we will use the Q345R material for more safe and durable operation. Please feel free to contact AIPU solids control if you have any other question

Oilfield poor boy degasser is also referred to mud gas separator or liquid gas separator. It is set ahead of shale shaker. Why we talk about it again?

Oilfield poor boy degasser information

Poor boy degasser is the nickname of drilling mud gas separator. It is used to get rid of retrained gas among drilling fluid. When we drill a well with sufficient gas, especially when we drill a gas well. The poor boy will help us to prevent blowout.

We know the invaded gas in drilling fluid will increase the air pressure. Then the well head will face danger of blowout under unbalanced pressure. At oilfield, the vertical poor boy can separate of large quantity toxic gas, the vent line is connected with flare ignition device

Oil drilling flare ignitor

Flare ignitor at oil drilling site is the equipment to burn harmful gas. The gas is separated out of drilling fluid via poor boy degasser. We know, for oilfield poor boy degasser, the vent line (gas discharge line) is requested at least 60 meter.

This vent line will be connected with flare ignition device. Thus we solve the problem of blow out also there is no toxic gas anymore after burning. Flare ignitor is the electrical one, controlled by remote panel and may use the liquified gas as burn source.

Aipu degassers and flare ignitor

Oilfield poor boy degasser and flare ignitor are hot products these days. Aipu has produced over 15 sets of such equipment for CNPC. They all requested APMGS1200 mud gas separator, with 60m vent line, also the flare ignition device

There are repeat orders from regular customers. Now there are 4 sets in our yard to be delivered. Maybe then, we'll get another order on 5 sets of degasser and ignitor.

Sincerely appreciate clients' trust and support. We will be committed to provide optimal solutions as appreciation. Please come to Aipu solids control for any demand or question on poor boy or ignitor. As well as other solids control items, of course
