Suppressing Barium Sulfate Crystallization with Hydroxycitrate: A Dual Nucleation and Growth Inhibitor

Designing (macro)molecules that can suppress crystallization is advantageous in natural, pathological, and commercial processes where mineralization has a detrimental impact. Control over this phase transformation is often one-dimensional, meaning that modifiers either block nucleation or impede crystal growth. Inhibitors of mineralization are predominantly composed of either phosphate or carboxylate moieties. It is less common to observe a modifier with only carboxylate functionality inhibit both nucleation and growth. Here, we explore a series of homologous poly(carboxylic acid)s as crystallization inhibitors of barium sulfate (barite), a pervasive and undesirable mineral scale in many industrial processes. Through bulk crystallization, time-resolved microscopy, and scattering measurements, we show that hydroxycitrate (a naturally derived small molecule) effectively inhibits barite nucleation. Moreover, combined microfluidics and atomic force microscopy measurements reveal that hydroxycitrate fully suppresses growth via the formation of a disordered layer on barite surfaces. The rate of barite growth prior to hydroxycitrate exposure could not be recovered over 12 h after removal of the modifier, indicating that growth was sustainably (and irreversibly) altered by exposure to hydroxycitrate. Thus, hydroxycitrate is a barite crystallization modifier capable of suppressing nucleation and irreversibly inhibiting surface growth.

“…Orubite et al investigated the performance of scale inhibition of extracts from leaves of Nypa fruticans plants on mild steel scale in HCl and compared them with the organic molecule 1,5-diphenylcarbazone. Nypa fruitcans showed an inhibition efficiency of 75.11%, while the inhibition efficiency of 1,5-diphenylcarbazone was found to be only 70.18% [125].…”

In the present time, more often, it has been seen that scaling has grown as widely and caused problems in the oilfield industry. Scaling is the deposition of various salts of inorganic/organic materials due to the supersaturation of salt-water mixtures. Many works have been proposed by researchers using different methods to solve the problem, of which scale inhibition is one of them. The scale inhibitors, particularly for antiscaling, have derived from natural and synthetic polymers. Among different polymers, inorganic and organic compounds (polyphosphates, carboxylic acid, ethylenediaminetetraacetic acid (EDTA), etc.) can effectively manage the oilfield scales of which many are toxic and expansive. Scale inhibitors of alkaline earth metal carbonate and sulfates and transition metal sulfide are commonly used in oilfield applications. Scale inhibition of metallic surfaces is an essential activity in technical, environmental, economic, and safety purposes. Scale inhibitors containing phosphorus appear to have significant achievements in the inhibition process despite its toxicity. However, phosphorus-based inhibitors can serve as supplements prompting eutrification difficulties. Besides these increasing environmental concerns, green scale inhibitors are renewable, biodegradable, and ecologically acceptable that has been used to prevent, control, and retard the formation of scale. Considering the facts, this review article summarized the concept of scale, various green scale inhibitors, types, mechanisms, comparative performance, significance, and future aspects of green scale inhibitors, which will shed light and be helpful for the professionals working in the oil and gas industries.

“…The hull extract inhibited scale growth better than the leaf extract, according to their findings. In another research, the inhibition efficiency of Nypafruitcans was 75.11 percent, while the inhibition efficiency of 1,5-diphenylcarbazone was only 70.18 percent [25]. Several other studies on creating green scale inhibitors have also been published in literature [26,27,28,29].…”

Scale deposits are a significant flow assurance issue in oil and gas operation with huge financial consequences. Not only does scaling drastically impair well performance, but it also has the potential to permanently destroy formation and equipment. Scale inhibitors are commonly used to prevent the accumulation of scales. A good scale inhibitor should be stable at the minimum effective inhibitor concentration under imposed operating conditions without interfering with or being affected by other chemical additives. However, most conventional scale inhibitors that possess these attributes, do not meet environmental restrictions which make them unfavorable for continuous application, prompting the industry to focus more on developing eco-friendly substitutes. This paper reviews the various types of scale inhibitors and general scale inhibition mechanism, summarizes scale concepts and ultimately, assesses the potential of flavonoids from natural plants as potential green scale inhibitors.
