lignosulfonate used in oil drilling

Lignosulfonates used in oil drilling

In oil drilling,If you drill in formations that have a lot of bentonite , you may need to use lignosulfonate mud (freshwater lignite mud). Bentonite in the formations are easily dispersed by water and bentonite will increase dispersion viscosity and rheology .

The lignite was added to the slurry water will control this problem and it is not expensive. Many people like to use this mud because it can be a weighting factor to nearly 19 PPG, but he still has very low value of low gravity solids .

You still have some drawbacks of this system. Lignosulfonate mud was not the stability of shale as other than low solids non-dispersed fluid mud PHPA, KCL base mud, and salt water system. In addition, certain additives such as carbonate can cause contamination in the mud and the mud properties deteriorate. You must be careful when using lignosulfonate mud with some chemical additives.

In the oil refining and oil industry for drilling oil and gas wells lignosulfonates are used as a reagent to control the basic parameters of drilling fluids. Also, they are a component of gelling systems, which are low-viscosity solutions with pH 2.5-3.0.

The formation of the gel leads to the redistribution of filtration flows and their better management, alignment profile pick-injection wells, restriction of water in the process, which in turn increases the recovery of oil. Using these systems lignosulfonates is possible by adsorbing properties of surface-active additives.

Just as in the mining industry, technical lignosulfonates are used to enhance various types of structures: mud pits, wells, etc.

Technical lignosulfonates are used:

  1. in chemical industry – as the stabilizer, dispersing agent for manufacture of briquetted means of plants protection; 
  2. in oil industry – as reagent for regulation of drilling agent;
  3. in foundry  – as a binding material for formation of casting  molds, an additive for  non-stick paints;
  4. in cement industry and manufacture of castables  – as cement softener and  binding material.

Technical requirements

Are developed according to TU 2455-028-00279580-2004. Technical lignosulfonates are produced in liquid and powder form.

1.Lignosulfonate helps create a desirable soil structure that facilitates water infiltration and helps hold water within the root zone.

2.Lignosulfonate and    stabilize or assists in the degradation of toxic substances such as: nicotine, aflatoxins, anti tics, shallots, and most organic pesticides.

3.Lignosulfonate have a very pronounced influence on the growth of plant roots. When Lignosulfonates and/or Lignosulfonates are applied to soil enhancement of root initiation and increased root growth.

4.Lignosulfonates are excellent foliar fertiliser carriers and activators. Their application in combination with trace elements and other plant nutrients, as foliar sprays, can improve the growth of plant foliage, roots, and fruits.

5.Regulate pH of soil and increase soil fertility.

The optimum pH range for most plants is between 5.5 and 7.0,Humus has direct function to balance the pH of soil,to make soil pH suitable for plants growth.
Humus could largely stabilized nitrogen storage and slow release,P is release from AL +in soil,also other microelement is in the form of easy-available by plants, meanwhile the beneficial fungi is active to produce different kind enzymes. to help to create a crumble structure of soil to increase macro elements and micro elements binding capacity and water holding capacity ,thus increase soil fertility.

6.Create good living environment for microbial mass.

  Lignosulfonate could directly improve soil structure thus to create good environment for microbial mas living environment,thus these microbial mas production will help to improve soil structure.

7.Promote the development of chlorophyll, sugars and amino acids in plants and aid in photosynthesis.

8.Stimulate seed germination in short time,Greatly increase harvest and fruits quality.

9.Greatly increase plants’ capability countering stress and disease.

Lignosulfonate can mobilize K absorption to regulate the stomata open and close on the leaves also promote metabolism, thus increase the plants’ ability under stressed conditions.

lignosulfonate works as binder

Lignosulfonate work as Binder

One of lignosulfonate famous property is binder is used in a wide range of applications. Lignosulfonates is a brown amorphous powder are the salts of lignosulfonic acid which is formed as a by-product when wood pulp is treated by the sulphite method during the manufacturing of paper.When such lignosulfonate become wet its binding capacity will exhibit.Meanwhile a lot of industries has some fines is different to cope with,lignosulfonate could bind them into larger part to take full use of them.

Coal Briquettes or refinery coke binder

In coal industry and refinery coke ,there always a lot of powder hard to handle,if put them directly into use lower heating energy ,Lignosulfonate could help to bind them into regular size  convert the powder into large easy to use.

Usually we mix some water and 3-5% of lignosulfonate of the total mixture the end product moisture is control less than 7%.

Dust suppressants(Dust control agent)and surface stabilizer

Lignosulfonate could work as effective dust control agent and surface stabilizer .As e all know lignin has strong ability to bind cellulose and fiber to increase tree firmness.So this feature could be much more environment-friendly and economic choice compared with other petroleum based products.

Lignosulfonate binds the road dust surface particle,when evaporate it will become the high-viscosity, naturally sticky material traps dust particles,then after sun heat will make a water resistant durable dust control surface.

Thus Lignosulfonate is naturally an adhesive, working as a binding agent  in pellets or compressed materials. Also could used in Plywood & particle board,Fertilizers , casting and so on.

Ceramics binder

Lignosulfonate has different compositions and molecular dimensions (because they are polymers that can be modified by the addition of organic or inorganic groups to the molecule). They are anionic derivatives of lignin, water soluble and surfactants. Lignosulfonates can increase mechanical green and dry strength in ceramic pieces. Also, they work as lubricants during extrusion or pressing . Additions of lignosulfonates to ceramic slips can vary from 0.1 to 2.0% and they are relatively inexpensive. For pressed tiles, 1% lignosulfonate can double mechanical strength (however often a black core appears). Lignosulfonates are often used to reduce shrinkage yet maintain after-forming mechanical strength (because reduced amounts of plastic clays are needed).

Animal feed pellets binder

Firstly could affect the animal growth digestion ,could supply natural soluble carbohydrate ,crucial for the metabolizable energy .

Carbon black

 Lignosulfonate can be applied as a binder for pyrolysis carbon black according to several patents. Lignosulfonate binders also give pellets their strength through solid type interactions (although to a less extent than starch) but also the interactions of the charged acid groups with the surface play a large role. These surface interactions could lead to stronger pellets but also might cause some problems if the surface morphology of the pyrolysis carbon black is not compatible. Nonetheless lignosulfonates present a cheap and promising option.

dust-suppression

Lignosulfonate used in dust control

Lignosulfonate could work as naturally binder as its original form of lignin to bind the cellulose and fiber,so it can be used binding agent in pellets or compressed materials,also could used as dust control agent,which will be much more environment friendly and lower cost compared with Chloride.

How lignosulfonate control the dust

Lignosulfonate binds the road dust surface particle,when evaporate it will become the high-viscosity, naturally sticky material traps dust particles,then after sun heat will make a water resistant durable dust control surface.
